Cocaine: An alkaloid ester extracted from the leaves of plants including coca. It is a local anesthetic and vasoconstrictor and is clinically used for that purpose, particularly in the eye, ear, nose, and throat. It also has powerful central nervous system effects similar to the amphetamines and is a drug of abuse. Cocaine, like amphetamines, acts by multiple mechanisms on brain catecholaminergic neurons; the mechanism of its reinforcing effects is thought to involve inhibition of dopamine uptake.Cocaine-Related Disorders: Disorders related or resulting from use of cocaine.Dopamine Uptake Inhibitors: Drugs that block the transport of DOPAMINE into axon terminals or into storage vesicles within terminals. Most of the ADRENERGIC UPTAKE INHIBITORS also inhibit dopamine uptake.Crack Cocaine: The purified, alkaloidal, extra-potent form of cocaine. It is smoked (free-based), injected intravenously, and orally ingested. Use of crack results in alterations in function of the cardiovascular system, the autonomic nervous system, the central nervous system, and the gastrointestinal system. The slang term "crack" was derived from the crackling sound made upon igniting of this form of cocaine for smoking.Self Administration: Administration of a drug or chemical by the individual under the direction of a physician. It includes administration clinically or experimentally, by human or animal.Conditioning, Operant: Learning situations in which the sequence responses of the subject are instrumental in producing reinforcement.

(Merck Index, 11th ed)Narcotics: Agents that induce NARCOSIS. Narcotics include agents that cause somnolence or induced sleep (STUPOR); natural or synthetic derivatives of OPIUM or MORPHINE or any substance that has such effects. They are potent inducers of ANALGESIA and OPIOID-RELATED DISORDERS.Benztropine: A centrally active muscarinic antagonist that has been used in the symptomatic treatment of PARKINSON DISEASE. Benztropine also inhibits the uptake of dopamine.Substance Withdrawal Syndrome: Physiological and psychological symptoms associated with withdrawal from the use of a drug after prolonged administration or habituation. The concept includes withdrawal from smoking or drinking, as well as withdrawal from an administered drug.Reward: An object or a situation that can serve to reinforce a response, to satisfy a motive, or to afford pleasure.Substance Abuse Detection: Detection of drugs that have been abused, overused, or misused, including legal and illegal drugs. Urine screening is the usual method of detection.Butyrylcholinesterase: An aspect of cholinesterase (EC 3.1.1.8).Street Drugs: Drugs obtained and often manufactured illegally for the subjective effects they are said to produce. They are often distributed in urban areas, but are also available in suburban and rural areas, and tend to be grossly impure and may cause unexpected toxicity.Dopamine Antagonists: Drugs that bind to but do not activate DOPAMINE RECEPTORS, thereby blocking the actions of dopamine or exogenous agonists. Many drugs used in the treatment of psychotic disorders (ANTIPSYCHOTIC AGENTS) are dopamine antagonists, although their therapeutic effects may be due to long-term adjustments of the brain rather than to the acute effects of blocking dopamine receptors. Dopamine antagonists have been used for several other clinical purposes including as ANTIEMETICS, in the treatment of Tourette syndrome, and for hiccup. Dopamine receptor blockade is associated with NEUROLEPTIC MALIGNANT SYNDROME.Substance-Related Disorders: Disorders related to substance abuse.Dopamine Agonists: Drugs that bind to and activate dopamine receptors.Heroin Dependence: Strong dependence, both physiological and emotional, upon heroin.Receptors, Dopamine D2: A subfamily of G-PROTEIN-COUPLED RECEPTORS that bind the neurotransmitter DOPAMINE and modulate its effects.

The mesocortical and mesolimbic dopaminergic systems originate here, including an important projection to the NUCLEUS ACCUMBENS. Overactivity of the cells in this area has been suspected to contribute to the positive symptoms of SCHIZOPHRENIA.Rats, Long-Evans: An outbred strain of rats developed in 1915 by crossing several Wistar Institute white females with a wild gray male. Inbred strains have been derived from this original outbred strain, including Long-Evans cinnamon rats (RATS, INBRED LEC) and Otsuka-Long-Evans-Tokushima Fatty rats (RATS, INBRED OLETF), which are models for Wilson's disease and non-insulin dependent diabetes mellitus, respectively.Corpus Striatum: Striped GRAY MATTER and WHITE MATTER consisting of the NEOSTRIATUM and paleostriatum (GLOBUS PALLIDUS). It is located in front of and lateral to the THALAMUS in each cerebral hemisphere. The gray substance is made up of the CAUDATE NUCLEUS and the lentiform nucleus (the latter consisting of the GLOBUS PALLIDUS and PUTAMEN). The WHITE MATTER is the INTERNAL CAPSULE.Conditioning (Psychology): A general term referring to the learning of some particular response.Saimiri: A genus of the family CEBIDAE consisting of four species: S. boliviensis, S. orstedii (red-backed squirrel monkey), S. sciureus (common squirrel monkey), and S. ustus.

The smokable form is a drug of abuse and is referred to as crank, crystal, crystal meth, ice, and speed.Opioid-Related Disorders: Disorders related or resulting from abuse or mis-use of opioids.Dextroamphetamine: The d-form of AMPHETAMINE. It is a central nervous system stimulant and a sympathomimetic. It has also been used in the treatment of narcolepsy and of attention deficit disorders and hyperactivity in children. Dextroamphetamine has multiple mechanisms of action including blocking uptake of adrenergics and dopamine, stimulating release of monamines, and inhibiting monoamine oxidase. It is also a drug of abuse and a psychotomimetic.Amphetamine: A powerful central nervous system stimulant and sympathomimetic.

It acts by inhibiting aldehyde dehydrogenase.

Solid-phase microextraction for cannabinoids analysis in hair and its possible application to other drugs. (1/3711)

This paper describes the application of solid-phase microextraction (SPME) to cannabis testing in hair. Fifty milligrams of hair was washed with petroleum ether, hydrolyzed with NaOH, neutralized, deuterated internal standard was added and directly submitted to SPME. The SPME was analyzed by GC-MS. The limit of detection was 0.1 ng/mg for cannabinol (CBN) and delta9-tetrahydrocannabinol (THC) and 0.2 ng/mg for cannabidiol (CBD). THC was detected in a range spanning from 0.1 to 0.7 ng/mg. CBD concentrations ranged from 0.7 to 14.1 ng/mg, and CBN concentrations ranged from 0.4 to 0.7 ng/mg. The effectiveness of different decontamination procedures was also studied on passively contaminated hair. The proposed method is also suitable for the analysis of methadone in hair; cocaine and cocaethylene can be detected in hair with SPME extraction after enzymatic hydrolysis.  (+info)

Cocaine metabolite kinetics in the newborn. (2/3711)

The study goal was to determine the half-life elimination of cocaine and benzoylecgonine (BZE) in the newborn. Three 0.3-mL blood samples were collected during the first day of life. Urine was collected once daily. Cocaine and BZE concentrations were determined by gas chromatography-mass spectrometry. An extraction method was developed for measuring low concentrations of cocaine and BZE in small (0.1 mL) blood samples. Cocaine had a half-life of 11.6 h in one subject. The half-life of BZE during the first day of life, based on blood data in 13 subjects, was 16 h (95% confidence interval [CI], 12.8 to 21.4 h). The half-life of BZE during the first week of life, based on urine data in 16 subjects, was 11.2 h (95% CI, 10.1 to 11.8 h). The novel extraction method for small blood sample volumes should be applicable to other basic drugs.  (+info)

Identification and quantification of cocaine N-oxide: a thermally labile metabolite of cocaine. (3/3711)

In this article, we report the identification and quantitation of cocaine N-oxide (CNO), a thermally labile oxidative metabolite, from both animal and human samples. The concentration of CNO is similar to the concentrations of cocaine in the samples analyzed. The technique used for the determination of CNO in this study is liquid chromatography-electrospray ionization mass spectrometry, which is necessary because CNO is converted to cocaine upon heating. This includes simple heating of aqueous solutions to temperatures in excess of 100 degrees C and analysis by gas chromatography-mass spectrometry (GC-MS), in which CNO is converted to cocaine in the injection port. The thermal conversion of CNO to cocaine is estimated to cause an over-reporting of cocaine levels by 10-20% when using GC-MS.  (+info)

Acquisition of nicotine discrimination and discriminative stimulus effects of nicotine in rats chronically exposed to caffeine. (4/3711)

Caffeine and nicotine are the main psychoactive ingredients of coffee and tobacco, with a high frequency of concurrent use in humans. This study examined the effects of chronic caffeine exposure on 1) rates of acquisition of a nicotine discrimination (0.1 or 0.4 mg/kg, s.c., training doses) and 2) the pharmacological characteristics of the established nicotine discrimination in male Sprague-Dawley rats. Once rats learned to lever-press reliably under a fixed ratio of 10 schedule for food pellets, they were randomly divided into two groups; 12 animals were maintained continuously on caffeine added to the drinking water (3 mg/ml) and another 12 control rats continued to drink tap water. In each group of water- and caffeine-drinking rats, there were six rats trained to discriminate 0.1 mg/kg of nicotine from saline and six rats trained to discriminate 0.4 mg/kg of nicotine from saline. Regardless of the training dose of nicotine, both water- and caffeine-drinking groups required a comparable number of training sessions to attain reliable stimulus control, although there was a trend for a slower acquisition in the caffeine-drinking group trained with 0.1 mg/kg of nicotine. Tests for generalization to different doses of nicotine revealed no significant differences in potency of nicotine between water- and caffeine-drinking groups. The nicotinic-receptor antagonist mecamylamine blocked the discriminative effects of 0.1 and 0.4 mg/kg nicotine with comparable potency and efficacy in water- and caffeine-drinking groups. There was a dose-related generalization to both the 0.1 and 0.4 mg/kg nicotine cue (maximum average of 51-83%) in water-drinking rats after i.p. treatment with d-amphetamine, cocaine, the selective dopamine uptake inhibitor GBR-12909, apomorphine, and the selective dopamine D1 receptor agonist SKF-82958, but not in caffeine-drinking rats (0-22%). There was no generalization to the nicotine cues after i.p. treatment with caffeine or the selective D2 (NPA) and D3 (PD 128,907) dopamine-receptor agonists in water- and caffeine-drinking rats. The dopamine-release inhibitor CGS 10746B reduced the discriminative effects of 0.4 mg/kg nicotine in water-drinking rats, but not in caffeine-drinking rats. There was no evidence of development of tolerance or sensitization to nicotine's effects throughout the study. In conclusion, chronic caffeine exposure (average, 135 mg/kg/day) did not affect the rate of acquisition of the nicotine discrimination, but it did reduce the dopaminergic component of the nicotine-discriminative cue. The reduction of the dopaminergic component of the nicotine cue was permanent, as this effect was still evident after the caffeine solution was replaced with water in caffeine-drinking rats. That nicotine could reliably serve as a discriminative stimulus in the absence of the dopaminergic component of its discriminative cue may differentiate nicotine from "classical dopaminergic" drugs of abuse such as cocaine and amphetamine.  (+info)

Effects of stimulants of abuse on extrapyramidal and limbic neuropeptide Y systems. (5/3711)

Neuropeptide Y (NPY), an apparent neuromodulating neuropeptide, has been linked to dopamine systems and dopamine-related psychotic disorders. Because of this association, we determined and compared the effects of psychotomimetic drugs on extrapyramidal and limbic NPY systems. We observed that phencyclidine, methamphetamine (METH), (+)methylenedioxymethamphetamine (MDMA), and cocaine, but not (-)MDMA, similarly reduced the striatal content of NPY-like immunoreactivity from 54% (phencyclidine) to 74% [(+) MDMA] of control. The effects of METH on NPY levels in the nucleus accumbens, caudate nucleus, globus pallidus, and substantia nigra were characterized in greater detail. We observed that METH decreased NPY levels in specific regions of the nucleus accumbens and the caudate, but had no effect on NPY in the globus pallidus or the substantia nigra. The dopamine D1 receptor antagonist SCH-23390 blocked these effects of METH, suggesting that NPY levels throughout the nucleus accumbens and the caudate are regulated through D1 pathways. The D2 receptor antagonist eticlopride did not appear to alter the METH effect, but this was difficult to determine because eticlopride decreased NPY levels by itself. A single dose of METH was sufficient to lower NPY levels, in some, but not all, regions examined. The effects on NPY levels after multiple METH administrations were substantially greater and persisted up to 48 h after treatment; this suggests that synthesis of this neuropeptide may be suppressed even after the drug is gone. These findings suggest that NPY systems may contribute to the D1 receptor-mediated effects of the psychostimulants.  (+info)

Age-related reductions in [3H]WIN 35,428 binding to the dopamine transporter in nigrostriatal and mesolimbic brain regions of the fischer 344 rat. (6/3711)

In the present study, we used the potent cocaine analog [3H]WIN 35, 428 to map and quantify binding to the dopamine transporter (DAT) within the dorsal striatum, nucleus accumbens, substantia nigra, and ventral tegmental area in young (6-month-old), middle-aged (12-month-old), and aged (18- and 24-month-old) Fischer 344 rats. Quantitative autoradiographic analysis of indirect [3H]WIN 35,428 saturation curves revealed two-site binding for all four brain regions in every age group. The percentage of binding to the high- or low-affinity sites did not differ with age or region and was approximately 50%. However, significant age-related decreases in the overall density (Bmax) of [3H]WIN 35,428-binding sites were observed in the striatum, nucleus accumbens, substantia nigra, and ventral tegmental area. The Bmax within all brain regions declined by more than 15% every 6 months, with the Bmax in the aged (24-month-old) group being approximately half that measured in the young adult (6-month-old) group. Competition experiments indicated that nomifensine also exhibited two-site binding to the DAT in Fischer 344 rats. No consistent age-related differences in binding affinities were noted with either [3H]WIN 35,428 or nomifensine. Taken together, these results support the hypothesis that functional DATs within the nigrostriatal and mesolimbic systems are down-regulated with age, without changing their affinity for ligands.  (+info)

A possible mode of cardiovascular actions of dopamine in dogs. (7/3711)

A possible mode of cardiovascular actions of dopamine was studied using ephedrine. In the dog pretreated with repeated administrations of ephedrine (total dose, 40 or 80 mg/kg, i.v.) or with combined administrations of ephedrine (total dose, 90 mg/kg, s.c. and i.v.) and reserpine (2 mg/kg, s.c., 24 hr previously), pressor responses to dopamine were eliminated and reversed to depressor responses whereas depressor responses to dopamine were potentiated. Positive chronotropic effects of dopamine were almost eliminated. Pressor and positive chronotropic effects of tyramine were almost abolished. Sympathomimetic effect of noradrenaline and adrenaline were potentiated while those of isoprenaline were inhibited. In the heart-lung preparation of ephedrine-treated dogs (total dose, 40 mg/kg, i.v.), cardiac stimulating effects of dopamine and tyramine were strongly depressed, and those of noradrenaline, adrenaline and isoprenaline were reduced to some extent. In the open-chest dogs, after pretreatment of cocaine (4 mg/kg, i.v.), pressor, positive inotropic and chronotropic effects of noradrenaline were potentiated, whilst those of tyramine were inhibited. Those of dopamine were not visibly altered, but depressor, negative chronotropic and inotropic effects of dopamine appeared at small doses. In the ephedrine-pretreated dogs, these sympathomimetic effects of dopamine and tyramine after cocaine were strongly depressed and those of noradrenaline were inhibited to a certain degree. The results obtained with ephedrine suggest that dopamine differs from other catecholamines and tyramine in the mode of cardiovascular actions.  (+info)

Pharmacodynamic actions of (S)-2-[4,5-dihydro-5-propyl-2-(3H)-furylidene]-1,3-cyclopentanedione (oudenone). (8/3711)

The pharmacodynamic actions of (S)-2-[4,5-dihydro-5-propyl-2(3H)-furylidene]-1,3-cyclopentanedione (oudenone) were studied in both anesthetized animals and isolated organs. Oudenone (10--40 mg/kg i.v.) induced an initial rise in blood pressure followed by a prolonged hypotension in the anesthetized rats. In unanesthetized spontaneously hypertensive rats (SHR), oudenone (5--200 mg/kg p.o.) caused a dose-related decrease in the systolic blood pressure. The initial pressor effect was diminished by pretreatments with phentolamine, guanethidine, hexamethonium and was abolished in the pithed rats. In addition, intracisternal administrations of oudenone (100--600 mug/kg) showed a marked increase in blood pressure in the anesthetized rats, suggesting that the pressor effect may be due to centrally mediated actions. Oudenone, given intra-arterially into the femoral artery (400--800 mug/kg), caused a long-lasting vasodilation in anesthetized dogs. At a relatively high dose (40 mg/kg i.v.), oudenone antagonized all pressor responses to autonomic agents and central vagus nerve stimulation in anesthetized rats and dogs, however, oudenone showed no anti-cholinergic,-histaminergic, beta-adrenergic and adrenergic neuron blocking properties.  (+info)

Cocaine abuse may contribute to the diverse forms of renal injury. We report a case of a pregnant woman who developed a large subcapsular renal haematoma after cocaine intoxication at 18-week gestation. She stabilized on conservative management and presented again at 29-week gestation with pre-eclampsia, acute renal failure and fetal demise. She required caesarean section delivery and intensive antihypertensive therapy to control severe pre-eclampsia associated with cocaine intoxication. This case is unique in that it is the first report of cocaine intoxication in pregnancy complicated by subcapsular haemorrhage. We discuss the possible mechanisms for the occurrence of this complication.. ...
Cannabinoid signaling via the type 1 cannabinoid (CB1) receptor modulates the effects of drugs of abuse and the response to exposure to stressors. In addition, exposure to stressors can alter the effects of drugs of abuse. This study examined the effects of exposure to chronic unpredictable stress (CUS) in CB1 receptor knockout (CB1 KO) mice and their wild-type (WT) littermates, using cocaine-conditioned place preference (CPP) to compare their response to cocaine. Mice were untreated or exposed to 2 weeks of CUS. After this period, the acquisition of a cocaine CPP was examined with one of three doses (3.2, 10.0, or 17.0 mg/kg) of cocaine. Untreated CB1 KO and WT mice both acquired the cocaine CPP; however, exposure to CUS enhanced the acquisition of the cocaine CPP in CB1 KO mice, but did not significantly alter the effects of cocaine in WT mice. Taken together, these findings support earlier evidence suggesting a role for the CB1 receptor in the response to stress as well as in the effects of cocaine.
Cocaine intoxication refers to the immediate and deleterious effects of cocaine on the body. Although cocaine intoxication and cocaine dependence can be present in the same individual, these syndromes present with different symptoms. Cocaine increases alertness, feelings of well-being, euphoria, energy, competence, sociability, and sexuality. Common side effects include anxiety, increased temperature, paranoia, restlessness, and teeth grinding. With prolonged use, the drug can cause insomnia, anorexia, tachycardia, hallucinations, and paranoid delusions. Possible lethal side effects include rapid heartbeat, abnormal heart rhythms, tremors, convulsions, markedly increased core temperature, renal failure, heart attack, stroke and heart failure. Depression with suicidal ideation may develop in heavy users. Finally, a loss of vesicular monoamine transporters, neurofilament proteins, and other morphological changes appear to indicate a long-term damage to dopamine neurons. Chronic intranasal usage ...
TY - JOUR. T1 - Self-administration of cocaine increases the release of acetylcholine to a greater extent than response-independent cocaine in the nucleus accumbens of rats. AU - Mark, Gregory. AU - Hajnal, Andras. AU - Kinney, Anthony E.. AU - Keys, Alan S.. PY - 1999. Y1 - 1999. N2 - Rationale: The neurochemical effects of psychostimulant exposure may depend on how these drugs are encountered. A useful method for examining this issue is to compare neurotransmitter release following response-dependent, or self-administered, drug exposure and response-independent exposure. Objectives: This experiment examined the effect of active and passive cocaine administration on acetylcholine (ACh) efflux in the shell region of the nucleus accumbens (NAc) in rats. Methods: One group of rats (CSA: cocaine self-administration) was trained to lever-press for intravenous infusions of cocaine (0.42 mg/kg per infusion) on a fixed-ratio-1 schedule of reinforcement. Cocaine infusions were accompanied by the onset ...
In the present study, we observed for the first time that the LV and coronary hemodynamic responses to a binge of cocaine were markedly and progressively attenuated in conscious, chronically instrumented dogs. In general, tolerance to cocaine was manifest on rechallenge after a single dose, although progressive decline in the hemodynamic and neurohumoral response to cocaine was observed with subsequent doses. Furthermore, the tolerance was not a function of the increase in baseline hemodynamic measurements before subsequent cocaine doses as the acute hemodynamic effects of cocaine were maintained when baseline hemodynamics were increased independent of cocaine. Finally, the mechanism of tolerance to the LV and systemic effects of repeated cocaine administration did not involve end-organ desensitization to the adrenergic effects of cocaine (Figs 4⇑ and 5⇑) but rather attenuated cocaine-induced catecholamine release as demonstrated by declines in plasma norepinephrine and epinephrine responses ...
On February 14, 2011, two Swiss psychologists published two years research on cocaine addiction. They found that addicts who gambled were less likely to use cocaine or to relapse on cocaine. They think gambling may refocus the brains "reward center" from cocaine to gambling. They said that psychotherapy should be used along with gambling. More research is being done on long-term relapse rates (the number of people who eventually start using cocaine again).[33][34][better source needed] However, a more recent study looked at prize-based contingency management: a treatment method that offers addicts chances to win prizes if they do not use cocaine. This study found that prize-based contingency management helped cocaine addicts stay off cocaine, whether or not they had gambled recently. This suggests that it is the chance of a reward, not the gambling itself, that helps cocaine addicts stay off of cocaine.[35] ...
We previously showed that maternal cocaine administration resulted in a decrease in fetal rat body weight [9]. The present study demonstrated that the maternal cocaine treatment caused a significant decrease in fetal brain weight, as compared with the saline control group. This finding is consistent with the previous report in pregnant C57BL/6 mice, in which maternal subcutaneous administration of cocaine from gestation days 12-18 produced significant decreases in fetal body and brain weight [27]. The pair-fed studies demonstrated that maternal undernutrition was not a likely mediator of the effects caused by cocaine [27, 28]. Moreover, our data indicate that cocaine decreases fetal brain/body weight ratio, suggesting that cocaine have higher affinity toxic effects on the fetal brain than the body. Dow-Edwards [29] reported that fetal brain had between 26-42% more concentration of cocaine than fetal plasma after 90 min following either 30 or 60 mg/kg cocaine given via intragastric intubation to ...
Cocaine has damaging effects on the brain, the heart and the mucous membrane of the nose. Significant symptoms of cocaine abuse are therefore paranoia, heart attacks and perforation of the nasal septum. The physical and mental effects of cocaine use are equally severe. The body and mind of a cocaine addict are both at risk.. Cocaine abuse and cocaine addiction cannot easily be distinguished because there may be no withdrawal symptoms. Similarly, users of crack cannot easily be distinguished from crack addicts. The boundary between drug use and drug abuse is not clear-cut and there may be no precise addiction symptoms.. The medical features and physical withdrawal characteristics of cocaine addiction are not as precise as they are in alcoholism or in addiction to some other drugs, such as heroin. Therefore the medical treatment of cocaine and crack abuse differs from that of other drugs.. Blood tests or urine tests would not distinguish between cocaine and crack but can show what other drugs have ...

A cocaine vaccine has the following potential advantages over existing drug treatments for cocaine dependence: it blocks cocaine from entering the brain; it may have fewer side effects than drugs that act on the brain, and it may produce better patient compliance and treatment outcome than existing oral drugs.. If a cocaine vaccine proves effective in human clinical trials, it will be ethically justifiable to use it to treat cocaine dependent patients who have given free and informed consent to its use. The major ethical issues are ensuring that the treatment is safe and effective and that patients give free and informed consent to treatment. Protection of patient privacy and confidentiality is not likely to be a major concern. The major uncertainties about its safety arise because it will not completely block the effects of smoked or injected cocaine. Patients who attempt to subvert its effects by increasing their cocaine dose or using other stimulant drugs may put themselves at risk of adverse ...
Cocaine can cause psychological dependence (a strong desire to continue using the medicine because of the "high" feeling it produces). This may lead to cocaine abuse (more frequent use and/or use of larger amounts of cocaine) and to an increased chance of serious side effects. Cocaine abuse has caused death from heart or breathing failure.. Use of cocaine as a local anesthetic for an examination or surgery is not likely to cause psychological dependence or other serious side effects. However, if cocaine is absorbed into the body too quickly, serious side effects can occur. Also, some people are especially sensitive to the effects of cocaine. Unwanted effects may occur in these people even with small amounts of the medicine. Before receiving cocaine as a local anesthetic, you should discuss its use with your doctor.. Cocaine is applied only by or under the immediate supervision of your doctor.. This product is available in the following dosage forms:. ...
... (Letter Report, 06/07/96, GAO/HEHS-96-80).. Pursuant to a congressional request, GAO reviewed the extent to which federally funded cocaine treatment therapies have proven successful and additional research initiatives that are needed to increase knowledge of cocaine treatment effectiveness.. GAO found that: (1) cocaine treatment research is still in its early stages; (2) preliminary study results have shown that relapse prevention, community reinforcement and contingency management, and neurobehavioral therapy may produce prolonged periods of abstinence among cocaine users; (3) relapse prevention programs have the highest abstinence rates, followed by community reinforcement and neurobehavioral programs; (4) community reinforcement programs have the highest retention rates, followed by relapse prevention and neurobehavioral programs; (5) pharmacological agents have not proven to be consistently effective in preventing cocaine use, and none ...
Cocaine addiction, a serious public health concern associated with significant medical, social, and economic consequences, is difficult to treat using traditional psychosocial and behavioral therapies. Despite testing of a number of different agents for cocaine dependency, there remains no proven pharmacologic treatment for cocaine addiction.. The addictive properties of cocaine have been associated with its actions on mesotelencephalic dopamine reward pathways in the central nervous system (CNS). Cocaine administration increases the levels of dopamine, a neurotransmitter associated with sensations of pleasure and reward. Therefore, blocking cocaine-induced increases in dopamine levels represents a valid pharmaceutical approach to the treatment of cocaine addiction.. Another neurotransmitter, gamma-aminobutyric acid (GABA), suppresses striatal dopamine release, and attenuates cocaine-induced increases in extracellular and synaptic dopamine levels in the striatum and nucleus accumbens in animal ...
A method for the determination of cocaine (COC), benzoylecgonine (BE), ecgonine methyl ester (EME), and ecgonine (ECG) in plasma by liquid chromatography-mass spectrometry (LC-MS-MS) was developed. The analytes were isolated from human plasma by subsequent solid-phase extraction and were separated on a Zorbax Eclipse XDB-C8 narrow-bore column using an ammonium acetate buffer/acetonitrile/methanol gradient. A Turbolonspray® source was used for ionization. The analytes were characterized by their particular molecular ion and several fragments. Multiple reaction monitoring (MRM) was used for isolation and quantitation. The assay was rapid, highly sensitive, and reliable. The method was applied to monitor the in vitro degradation of cocaine in plasma. Fresh unpreserved and preserved (0.25 % KF) plasma samples were spiked with 1000 ng cocaine/mL. Aliquots of both series were stored at 4°C and 20°C and were analyzed at selected storage times of up to 15 days. In all samples, degradation of cocaine ...
Cocaine abuse is a serious health problem in many areas of the world, yet there are no proven effective medications for the treatment of cocaine dependence.Preclinical studies suggest that the reinforcing effect of cocaine that promotes its abuse is mediated by blockade of the presynaptic dopamine transporter. This results in increased dopamine activity in the mesolimbic or meso-accumbens dopamine reward system of brain. Development of new medications to treat cocaine dependence has focused on manipulation of this dopamine system, either by direct action on dopamine binding sites (transporter or receptors) or indirectly by affecting other neurotransmitter systems that modulate the dopamine system. In principle, a medication could act via one of three mechanisms: (i) as a substitute for cocaine by producing similar dopamine effects; (ii) as a cocaine antagonist by blocking the binding of cocaine to the dopamine transporter; or (iii) as a modulator of cocaine effects by acting at other than the ...
Cocaine is a powerfully addictive stimulant drug. The powdered form of cocaine can be snorted or dissolved in water and then injected. "Crack" is the street name given to the form of cocaine that has been processed to make a rock crystal, which, when heated, produces vapors that are smoked. The term "crack" refers to the crackling sound produced by the rock as it is heated. The street names of cocaine are coke, snow, flake and blow.. Cocaine usually makes the user feel euphoric and energetic, but also increases body temperature, blood pressure, and heart rate. Users risk heart attacks, respiratory failure, strokes, seizures, abdominal pain, and nausea. In rare cases, sudden death can occur on the first use of cocaine or unexpectedly afterwards.. The National Survey on Drug Use and Health (NSDUH) estimates that in 2008 there were 1.9 million current (past-month) cocaine users, of which approximately 359,000 were current crack users. Adults aged 18 to 25 years have a higher rate of current cocaine ...
Wholesale crack traffickers purchase cocaine in kilogram or multikilogram allotments from traditional cocaine sources, including Colombian and Mexican organizations. They package the cocaine into ounce quantities or convert it into crack and then divide it into ounces for sale at the next level. Wholesalers usually are large groups responsible for most of the interstate transportation of crack and cocaine intended for crack conversion.. Retail distributors convert powdered cocaine into crack, usually in their own kitchens, using a safe and simple method of converting cocaine into cocaine base. Although it produces a product higher in purity than coca paste, the crack conversion process does not eliminate all of the impurities in the cocaine. Adulterants such as lidocaine, procaine, and benzocaine survive the crack conversion process and are inhaled by the user. Federal mandatory minimum sentences are higher for crack than for powdered cocaine, but crack cocaine provides a much higher profit ...
Criteria for Discontinuation Following Initiation:. Participants will be discharged if they have a positive breath test indicating use of alcohol or a urine test indicating illicit use of drugs while in the MED-VAMC, if they do not comply with study procedures, or if they do not tolerate the study drugs.. Subject Selection Criteria Rationale for Route of Administration:. Participants are required to have used cocaine by the IV or smoked route to avoid exposing participants to drugs by routes of administration that produce more intensive interoceptive effects than usually used by the participants. Prior experience with smoked cocaine is allowed (rather than restricting the population to those with experience with IV cocaine) because smoked cocaine reaches brain sites of action as rapidly as does intravenously administered cocaine and smoked cocaine produces effects that are comparable to IV cocaine. Speed of administration (and rate of delivery to brain) of stimulant drugs likely impacts ...
5-HT1B receptors (5-HT1BRs) modulate behavioral effects of cocaine. Here we examined the effects of the 5-HT1BR agonist CP94253 on spontaneous and cocaine-induced locomotion and on cocaine-primed reinstatement of conditioned place preference (CPP) in male mice given daily repeated injections of either saline or cocaine (15 mg/kg, IP) for 20 days. In the locomotor activity experiment, testing occurred both 1 and 20 days after the final injection. In the CPP experiment, mice underwent conditioning procedures while receiving the last of their daily injections, which were given either during or ≥2 h after CPP procedures. The CPP procedural timeline consisted of baseline preference testing (days 12-13 of the chronic regimen), conditioning (days 14-19, 2 daily 30-min sessions separated by 5 h), CPP test (day 21), extinction (days 22-34; no injections), CPP extinction test (day 35; no injections), and reinstatement test (day 36). Mice that had not extinguished received additional extinction sessions prior to
Cocaethylene (ethylbenzoylecgonine) is the ethyl ester of benzoylecgonine. It is structurally similar to cocaine, which is the methyl ester of benzoylecgonine. Cocaethylene is formed by the liver when cocaine and ethanol coexist in the blood. Cocaethylene is the byproduct of concurrent consumption of alcohol and cocaine as metabolized by the liver. Normally, metabolism of cocaine produces two primarily biologically inactive metabolites-benzoylecgonine and ecgonine methyl ester. The hepatic enzyme carboxylesterase is an important part of cocaines metabolism because it acts as a catalyst for the hydrolysis of cocaine in the liver, which produces these inactive metabolites. If ethanol is present during the metabolism of cocaine, a portion of the cocaine undergoes transesterification with ethanol, rather than undergoing hydrolysis with water, which results in the production of cocaethylene. cocaine + H2O → benzoylecgonine + methanol (with liver carboxylesterase 1) benzoylecgonine + ethanol → ...

Fig. 1 Prior alcohol use enhances persistence, motivation, and compulsivity for cocaine self-administration.. (A) Drug treatment paradigm to study alcohol and cocaine coadministration. Access to voluntary alcohol (10% alcohol, 2 hours per day) and voluntary cocaine (self-administration, 0.8 mg/kg per injection) was restricted to 3 p.m. to 5 p.m. and 11 a.m. to 2 p.m., respectively, to avoid metabolic interaction between the two drugs. (B) Alcohol self-administration. Animals in the alcohol-primed group began drinking alcohol on day 1 of the paradigm; animals in the alcohol-concurrent group began drinking on day 11. All groups start cocaine self-administration (0.8 mg/kg per infusion) on day 11. The average alcohol intake during the alcohol-priming period was 1 g/kg during the first 5 days, increasing to 1.2 g/kg during the second 5 days. Alcohol intake was similar in the alcohol-primed versus alcohol-concurrent groups from days 11 to 32 [two-way repeated-measures (RM) analysis of variance ...

N2 - Repeated cocaine intoxication can result in the development of behavioral sensitization in animals and psychosis in humans, phenomena that have been associated with alterations in dopamine (DA) function. Using electrophysiologic and autoradiographic techniques, modifications of central serotonin (5‐hydroxytryptamine; 5‐HT) systems were investigated in rats treated with a regimen of cocaine administration that produced behavioral sensitization. The inhibitory response of single 5‐HT neurons in the dorsal raphe (DR) to (−)‐cocaine, the 5‐HT uptake inhibitor fluoxetine or the 5‐HT1A agonist 8‐hydroxy‐2‐[di‐N‐propylamino]tetralin (8‐OHDPAT) was significantly enhanced in cocaine‐treated rats. Furthermore, several brain areas that contain either cell bodies (DR) or terminals ...

If people use cocaine, they may take too much and get sick or even die. This is called an "overdose". When people take cocaine, they get intoxicated as well. When a person is intoxicated, they may do dangerous things, such as having unsafe sex with a person they do not know, or getting into a violent fight with a person. If a person uses cocaine for a long time, they can start to get strange feelings, like there are bugs crawling under their skin, or they can get paranoia (a feeling that there are people that want to hurt them). Cocaine is a very addictive drug. It can lead to psychological and/or physical dependence. When a person is addicted to a drug, they might do bad or criminal acts in order to get money for more drugs, such as crimes (for example theft, robbery, fraud, or prostitution). If the person tries to stop using cocaine, they will go through cocaine withdrawal. Another danger from using cocaine is the risk of infection when using unsafe ways of taking cocaine (like using dirty ...
Problem statement: It has been well documented that drugs of abuse such as cocaine can cause enhanced progression of HIV-Associated Neuropathological Disorders (HAND), the underlying mechanisms mediating these effects remain poorly understood. Approach: In present study, we explored the impact of cocaine exposure (I and 10 μM) on the dendritic beading in rat primary hippocampal neurons. Using the approach of transfection with green fluorescent protein, we observed significant dendritic swelling in hippocampal neurons exposed to 10 μM but not 1 μM of cocaine when compared with the saline treated group. Results: Cocaine exposure also resulted in decreased expression of the synaptic plasticity gene, Arc as evidenced by Western blotting. Intriguingly, cocaine exposure of primary neurons in the presence of the neurotoxin-HIV envelope protein gp 120, resulted in increased enhancement of neuronal beading as compared with exposure of neurons to either agent alone. Conclusion: Taken together these
senior study author Dr. Eric Nestler of New York Citys Mount Sinai School of Medicine said in a statement.. Nestler and colleagues combined highly sensitive genetic isolation and screening techniques to study regulation of gene transcription in the brains of mice repeatedly receiving cocaine. The researchers also found a previously unrecognized family of genes -- called the sirtuins -- involved in cocaine addiction. Chronic cocaine administration was linked with an increase in sirtuin gene transcription while increased sirtuin activity was associated the rewarding effects of cocaine being augmented, while pharmacological inhibition of sirtuins reduced the rewarding effects of cocaine and the motivation to self-administer the drug.. ...

S.. PY - 1993/1/1. Y1 - 1993/1/1. N2 - The effects of cocaine on cyclic reproductive function in females remain largely unknown. In this study, we sought to define the range of doses of cocaine effective in disrupting estrous cyclicity and inhibiting ovulation. Estrous cyclicity was monitored daily by vaginal cytology. Group 1 consisted of rats receiving no treatment. Group 2 consisted of rats injected daily with saline s.c. Groups 3 to 6 consisted of rats injected with 1, 5, 10 and 20 mg/kg/day of cocaine HCl s.c., respectively. Group 7 consisted of rats that were food-restricted to allow weight gains comparable to those of group 6. Our results indicate a dose- dependent effect of cocaine on estrous cyclicity with an estimated IC50 of 8.5 mg/kg/day (i.e., the dose of cocaine required to inhibit the ...

The results of the present study demonstrate that cocaine self-administration alters dopamine transporter binding and that these changes follow a clear progression over time. In the initial stages of cocaine self-administration (5 d), DAT binding site levels were moderately reduced, whereas after more prolonged cocaine self-administration (3.3 months), large increases in the density of DAT sites were evident. These increases in DAT binding levels persisted even after protracted periods of self-administration (1.5 years). A key characteristic of the alterations in DAT binding was the dose-dependent nature of the effects. Chronic cocaine self-administration at the higher cocaine dose yielded more intense increases in the density of the DAT binding sites and encompassed a wider expanse of the caudal PCS than self-administration of the lower dose. Finally, the majority of significant changes in DAT binding density that occurred after chronic and long-term cocaine self-administration were focused in ...
Protein interacting with C-kinase 1 (PICK1) is a widely expressed scaffold protein known to interact via its PSD-95/discs-large/ZO-1 (PDZ)-domain with several membrane proteins including the dopamine (DA) transporter (DAT), the primary target for cocaines reinforcing actions. Here, we establish the importance of PICK1 for behavioral effects observed after both acute and repeated administration of cocaine. In PICK1 knock-out (KO) mice, the acute locomotor response to a single injection of cocaine was markedly attenuated. Moreover, in support of a role for PICK1 in neuroadaptive changes induced by cocaine, we observed diminished cocaine intake in a self-administration paradigm. Reduced behavioral effects of cocaine were not associated with decreased striatal DAT distribution and most likely not caused by the ∼30% reduction in synaptosomal DA uptake observed in PICK1 KO mice. The PICK1 KO mice demonstrated preserved behavioral responses to DA receptor agonists supporting intact downstream DA ...

Background Homologous cocaine self-administration procedures in laboratory animals and humans may facilitate translational research for medications development to treat cocaine dependence. This study, therefore, sought to establish choice between cocaine and an alternative reinforcer in rhesus monkeys responding under a procedure back-translated from previous human studies and homologous to a human laboratory procedure described in a companion paper. Methods Four rhesus monkeys with chronic indwelling intravenous catheters had access to cocaine injections (0, 0.043, 0.14, or 0.43 mg/kg/injection) and food (0, 1, 3, or 10 1 g banana-flavored food pellets). During daily 5 h sessions, a single cocaine dose and a single food-reinforcer magnitude were available in 10 30-min trials. During the initial
Cocaine abuse has become the most abused major stimulant in the USA and statistics show that emergency room visits for it are increasing. Cocaine abuse has been around for as long as anyone can remember.. Derived from the "innocent" cocoa plant, it is considered the "champagne" of drugs, one of its street names. There is an array of street names describing the different uses.. There are various ways that an addict will use this drug, amongst them being snorting, smoking one of the derivatives known as crack or rock. Historically, cocaine was known as the rich mans drug. This is changing rapidly as teenagers have found a new sensation in mixing it with marijuana.. The highly addictive nature of cocaine makes it an extremely dangerous drug and many a user will tell you that theyre not addicted. This is so far from the truth to be ridiculous. If cocaine abuse isnt a problem to the addict, how come they are still using it?. No-one would willingly remain addicted. The penalties are extreme. ...

Because DSM-IV cocaine dependence (CD) is heterogeneous, it is not an optimal phenotype to identify genetic variation contributing to risk for cocaine use and related behaviors (CRBs). We used a cluster analytic method to differentiate homogeneous, highly heritable subtypes of CRBs and to compare their utility with that of the DSM-IV CD as traits for genetic association analysis. Clinical features of CRBs and co-occurring disorders were obtained via a poly-diagnostic interview administered to 9,965 participants in genetic studies of substance dependence. A subsample of subjects (N = 3,443) were genotyped for 1,350 single nucleotide polymorphisms (SNPs) selected from 130 candidate genes related to addiction. Cluster analysis of clinical features of the sample yielded five subgroups, two of which were characterized by heavy cocaine use and high heritability: a heavy cocaine use, infrequent intravenous injection group and an early-onset, heavy cocaine use, high comorbidity group. The utility of ...

We investigated the interaction between ontogeny, stress and environment where the drug is administered on the behavioral sensitization to cocaine and related neuroadaptations. This study was divided in two parts. In the first one we evaluated the behavioral sensitization to cocaine and alterations of glutamate receptors and tyrosine hydroxylase enzyme following repeated cocaine administrations or stress exposure on adolescent rats. These alterations were evaluated from adolescence to adulthood. The results showed that cocaine administration during adolescence produced long-term behavioral sensitization to cocaine until adulthood and increased of GluR1 glutamate receptor subunit in the medial prefrontal cortex. The stress-induced behavioral sensitization was evident during adolescence but did not reach adulthood. In the second part, we evaluated the environmental modulation of behavioral sensitization to cocaine and alterations of CREB and upstream kinases activation in adult rats. The results ...

There is a chemical out and about in the world today called cocaine hydrochloride. We commonly refer to it as cocaine. Some cocaine users, in order to make the drug more potent, remove the hydrochloride, a process call "freebasing." The solid form of this freebased cocaine is called "crack", getting its name from the snapping and cracking sounds it makes when being heated and smoked. Once considered a rich mans drug, it is currently being sold at prices that even juveniles can afford-at least in the beginning. Once addicted, the crack habit increases along with the cost.

WILMINGTON - United States Attorney Thomas G. Walker announced that in federal court today Senior United States District Judge James C. Fox sentenced LARRY DONNELL TAYLOR, 40, of Dunn, North Carolina, to 240 months in prison followed by 5 years of supervised released for conspiracy to distribute and possess with intent to distribute 280 grams or more of cocaine base (crack) and 5 kilograms or more of cocaine and conspiracy to commit money laundering. TAYLOR previously pled guilty to these charges on January 2, 2013.. The investigation revealed that from at least 2000 to October 2012, TAYLOR was an upper-level drug trafficker who received large quantities of cocaine and crack cocaine from several suppliers. Upon receiving the drugs, TAYLOR utilized several individuals to distribute his drugs throughout the Eastern District of North Carolina. TAYLOR also converted substantial quantities of cocaine into crack cocaine for resale.. On October 3, 2012, investigators served a federal arrest warrant on ...
The purpose of this data collection was to investigate the possible increase in gang involvement within cocaine and rock cocaine trafficking. Investigators also examined the relationships among gangs, cocaine trafficking, and increasing levels of violence. They attempted to determine the effects of increased gang involvement in cocaine distribution in terms of the location of an incident, the demographic profiles of suspects, and the level of firearm use. They also looked at issues such as whether the connection between gangs and cocaine trafficking yielded more drug-related violence, how the connection between gangs and cocaine trafficking affected police investigative processes such as intra-organizational communication and the use of special enforcement technologies, what kinds of working relationships were established between narcotics units and gang control units, and what the characteristics were of the rock trafficking and rock house technologies of the dealers. Part 1 (Sales Arrest ...
Several risk factors for cocaine addiction have been identified. These include endogenous (presumably genetic) factors (such as trait impulsivity and novelty seeking), exogenous (environmental) factors (such as prior use and dependence on nicotine, alcohol, or marijuana), and psychiatric disorders (such as lifetime personality disorder or attention deficit hyperactive disorder). Controlling for multiple predictors, alcohol dependence, together with mood disorder, is second in importance-after cannabis dependence-as predictors of cocaine dependence (2). Although many rodent studies have tested cross-sensitization between different drug classes, the significance of these studies to drug addiction vulnerability is often confounded by behavioral models that focus on the early stages of drug experimentation rather than on addiction. Here, we have used a rodent model of compulsive cocaine use to test, on both a behavioral and molecular level, the epidemiological hypothesis that alcohol acts as a ...
Cocaine is a powerfully addictive stimulant that directly affects the brain.. Pure cocaine was first extracted from the leaf of the Erythroxylon coca bush in the mid-19th century. In the early 1900s it became the main stimulant drug used in most of the tonics and elixirs that were developed to treat a wide variety of illnesses. It quickly became popular as an ingredient in patented medicines (throat lozenges and tonics) and other products (such as Coca Cola, from which it was later removed).. Concern soon mounted due to instances of addiction, psychotic behavior, convulsion, and death. A series of steps, including passage of the Pure Food and Drug Act of 1906, were taken to combat health and behavioral problems associated with the use of cocaine. Finally, the Harrison Act of 1914 outlawed the use of cocaine in over-the-counter products and made it available only by prescription. Cocaine use soon dropped dramatically and remained at minimal levels for nearly half a century.. In the 1960s, illicit ...
Irrespective of ongoing analysis into the cure of cocaine abuse, efficient medications for acute toxicity or Long-term addiction are still lacking. Cocaine capabilities being a molecular blocker of dopamine transporters, and thus drug detoxification inside the CNS by using its displacement from transporter binding websites poses a fascinating conundrum. We hypothesized that an immunopharmacotherapeutic treatment method technique for cocaine-connected toxicity would endorse drug efflux in the CNS via binding cocaine from the periphery. Cocaine vaccines circumvent the prerequisite of the central mechanism to effect cocaine trafficking, a barrier which includes confirmed insurmountable to other pharmacotherapeutic strategies ...
People who are addicted to cocaine have less grey matter in the frontal parts of their brain and in their hippocampi. The frontal parts of the brain are important for paying attention and organising ones behaviour while the hippocampus is important in learning and memory. A team of researchers led by Nelly Alia-Klein at the U.S. Department of Energys Brookhaven National Laboratory have found that people with a certain genetic make up may be more vulnerable to the adverse effects of cocaine use than other people. The researchers studied 82 people. 40 of them were addicted to cocaine and 42 were healthy controls. The researchers took DNA samples and scanned the subjects brains. The cocaine addicts with a low MAOA (monoamine oxidase A) genotype had lower grey-matter density in the frontal parts of the brain than the other cocaine addicts. The genes are responsible for levels of MAOA, an enzyme which regulates neurotransmitters such as serotonin and dopamine that regulate mood ...

Substantial epidemiological studies suggest that not only, being one of the reasons for the transmission of the human immunodeficiency virus (HIV), but drug abuse also serves its role in determining the disease progression and severity among the HIV infected population. This article focuses on the drug cocaine, and its role in facilitating entry of HIV into the CNS and mechanisms of development of neurologic complications in infected individuals. Cocaine is a powerfully addictive central nervous system stimulating drug, which increases the level of neurotransmitter dopamine (DA) in the brain, by blocking the dopamine transporters (DAT) which is critical for DA homeostasis and neurocognitive function. Tat protein of HIV acts as an allosteric modulator of DAT, where as cocaine acts as reuptake inhibitor. When macrophages in the CNS are exposed to DA, their number increases. These macrophages release inflammatory mediators and neurotoxins, causing chronic neuroinflammation. Cocaine abuse during HIV
Exposure of fetal mouse brain cocultures to cocaine results selectively in the loss of neurites followed by neuronal death. By using enriched neuronal cultures, we here demonstrate that disappearance of neurons, when cultured with cocaine, is caused by apoptosis, based on (1) characteristic morphology of apoptotic nuclei at the level of neurons but not of glial cells by optic microscopy, and on total cell pellets by electron microscopy; (2) fragmentation of total DNA with a typical "ladder" pattern on agarose gels; (3) extensive in situ DNA fragmentation labeling (TUNEL method); and (4) prevention of cell loss by cycloheximide. The major metabolites of cocaine have no detectable effects on neurons, indicating that apoptosis is due to cocaine itself. Inappropriate neuronal apoptosis in cocaine-exposed fetal brain could perturb the neurodevelopmental program and contribute to the quantitative neuronal defects that are too frequently reported in the offspring of cocaine-abusing pregnant women. ...

Cocaine use is a common disorder of neuroplasticity that triggers cellular and molecular alterations in brain reward systems, mainly in the dorsal striatum. Compulsive cocaine use and cocaine relapse is due to drug-induced neuroadaptations in reward-related learning and memory processes, and these cause hypersensitivity to cocaine-associated cues, impulsive decision making and abnormal habit-like learned behaviors that are insensitive to adverse consequences [3]. Cocaine-induced neuroplasticity changes in the mesolimbic dopamine system mediate psychomotor sensitization and cocaine-seeking behaviors. Hollander et al. [4] demonstrated that cocaine-seeking behavior in rats is modulated by miR-212, which decreases the activity of a group of genes (CREB, TORC1, Raf1 and SPRED1), thus limiting the transition to an uncontrolled intake of cocaine in animals exposed to the drug over a long period of time. Interestingly, artificially increasing miR-212 expression leads to decreased cocaine intake under ...
A single cocaine injection in drug-experienced animals during an extended drug-free period triggers a synaptic depression whereas the same treatment in drug-naive animals does not. Thus, repeated cocaine dramatically alters an animals response to subsequent cocaine during extended withdrawal. This type of shift has been referred to as metaplasticity, a condition in which the history of activity in a given neuron or synapse alters the magnitude or direction of plasticity in response to subsequent stimulation (Abraham and Bear, 1996; Bear, 2003). A compelling example of metaplasticity comes from visual deprivation experiments. Reduction in activity of visual cortical neurons can shift the response of these neurons to a given evoked stimulus from long-term depression to long-term potentiation (LTP) (Kirkwood et al., 1996; Bear, 2003). As in other forms of metaplasticity, repeated cocaine experience appears to shift the threshold necessary for generating a plastic response, in this case, synaptic ...
Behavioral sensitization to cocaine reflects neuroadaptive changes that intensify drug effects. However, repeated cocaine administration does not induce behavioral sensitization in all male Sprague-Dawley rats. Because cocaine inhibits the dopamine (DA) transporter (DAT), we investigated whether altered DAT function contributes to these individual differences. Freely moving rats had electrochemical microelectrode/microcannulae assemblies chronically implanted in the nucleus accumbens so that exogenous DA clearance signals were recorded simultaneous with behavior. The peak DA signal amplitude (Amax) and efficiency of clearance (k) were used as indices of in vivo DAT function. Low and high cocaine responders (LCRs and HCRs, respectively) were identified based on their locomotor responsiveness to an initial injection of cocaine (10 mg/kg i.p.). Consistent with DAT inhibition, cocaine elevated Amax and reducedk in HCRs, but not in LCRs. The same dose of cocaine was administered for six additional ...
Drug addiction is a chronic, relapsing disorder in which compulsive drug-seeking and drug-taking behavior persists despite serious negative consequences.There is strong evidence that the dopaminergic system that projects from the ventral tegmental area (VTA) of the midbrain to the nucleus accumbens (NAc), and to other forebrain sites, is the major substrate of reward and reinforcement for both natural rewards and addictive drugs. Cocaine binds strongly to the dopamine-reuptake transporter, preventing the reuptake of dopamine into the nerve terminal. Because of this blocking effect, dopamine remains at high concentrations in the synapse and continues to affect adjacent neurons, producing the characteristic cocaine "high." Activated D1 receptor activates the PKA signaling pathway, and this pathway plays a critical role in mediating the behavioral responses to cocaine administration. Cocaine-induced neuroadaptations, including dopamine depletion, may underlie craving and hedonic dysregulation ...

Within Detroit, the primary emphasis continues to be placed on targeting major cocaine distribution and transportation organizations. The larger metropolitan areas of Detroit continue to experience high availability in cocaine trafficking and abuse. The availability of the drug is increasing the need for cocaine addiction treatment in the city.. A large majority of the cocaine transported to Detroit by these Mexican and African American organizations is transported in personal vehicles equipped with traps and/or concealed within the legitimate cargo on large semi tractor-trailers. As the venues for transportation and distribution expand the need for cocaine drug rehab, education and addiction treatment becomes a serious issue in the area. City officials believe that the key to addiction recovery lies within the concept of drug rehab Michigan..

Stress enhances the behavioral effects of cocaine, perhaps via hypothalamic-pituitary-adrenal (HPA) axis activity. Yet, compared to Fischer 344 (F344) rats, Lewis rats have hyporesponsive HPA axis function and more readily acquire cocaine self-administration. We hypothesized that stress would differentially affect cocaine behaviors in these strains. The effects of three stressors on the discriminative stimulus and response rate effects of cocaine were investigated. Rats of both strains were trained to discriminate cocaine (10 mg/kg) from saline using a two-lever, food-reinforced (FR10) procedure. Immediately prior to cumulative dose (1, 3, 10 mg/kg cocaine) test sessions, rats were restrained for 15-min, had 15-min of footshock in a distinct context, or were placed in the shock-paired context. Another set of F344 and Lewis rats were tested similarly except they received vehicle injections to test if stress substituted for cocaine. Most vehicle-tested rats failed to respond after stressor exposures.
According to the United Nations Office on Drugs and Crimes 2013 drug report, the United States consumes 36.8 percent of the global cocaine demand each year.

Client: National Institute of Justice, US Department of Justice. Authors/Consultants: Homer J. A system dynamics model reproduces a variety of national indicator data reflecting cocaine use and supply over a 15-year period and provides detailed estimates of actual underlying prevalence. Sensitivity testing clarifies the source of observed trends. Alternative scenarios with possible policy implications were simulated and projected. In one analysis, the model was applied to determine the potential impact of policies involving a relaxation of law enforcement. The model suggests that a policy that eliminates both drug seizures and retail-level arrests would reduce the criminal justice load, but could lead to a large increase in cocaine use and addiction..

Back. Brain and Cocaine. Techniques of positron emission tomography (PET) have shown in human cocaine abusers some of the ways by which cocaine produces its pleasurable effects as they are occurring. Researchers suggest that cocaine works in large part by occupying or blocking dopamine transporter (DAT) sites, thereby preventing reuptake of dopamine by the brain cells that release it, which then allows higher concentrations of dopamine to remain available in the brain longer than normal. It is this abnormally long presence of dopamine in the brain that is believed to cause the high and other effects associated with cocaine use.. Comparing the functioning of the dopamine system in the brains of chronic cocaine users with that in non-users, the researchers found that, compared to the non-users, the cocaine-dependent group showed reduced dopamine responses to the drug in the striatum, a region of the brain linked to motivation control and reward. At the same time, they found an abnormal increase in ...
The Quest Diagnostics Drug Testing Index showed that positivity for cocaine declined 20.7 percent among federally mandated, safety-sensitive workers, to 0.46 percent for the first six months of 2007, compared to 0.58 percent for all of 2006. Among the general workforce, positivity for cocaine declined 15.3 percent, falling to 0.61 percent for the period between January and June 2007 compared to 0.72 percent for 2006.. "Not only did the positivity rate fall to its lowest level since Quest Diagnostics began reporting on cocaine rates a decade ago, but also the decline was truly across the board, falling by double-digits in all but one of nine regions of the country," said Barry Sample, Ph.D., director of Science and Technology for the Employer Solutions division of Quest Diagnostics. "While it is too soon to point to a trend, the significant decline in positivity rates in different workforce categories and across regions may suggest that our nations workers are choosing not to use cocaine or that ...
Seattle police say a 73-year-old man was arrested after he tried to snort cocaine during a traffic stop. During the stop, Abts-Olsen checked the mans license and registration and says he startled the man when he returned to the vehicle, causing him to spill cocaine on his hands and the floor of the car. Police say the man initially tried to brush away the white powder, denied it was cocaine and said he had vitamins in his possession. Eventually, the man told police snorting cocaine in the middle of a traffic stop was perhaps a poor decision. Posted By Persist
Reversibility of Cocaines Cardiovascular Effects in Vivo. We have found that an efficient cocaine hydrolase will reduce hypertensive responses to cocaine in the rat and that such an enzyme can be beneficial even after responses to the drug have become established. It is particularly important that an injection of CocE restored baseline blood pressure in rats that received a near-LD50 dose of cocaine. This finding is directly relevant to the clinical utility of hydrolases for rescue from cocaine overdose.. The rapid restoration of normotension shows that cocaines binding to its sites of action is reversible in vivo on a time scale of seconds. Our data confirm previous indications that cocaines high affinity for its target, the catecholamine transporter, is compatible with ready reversibility. Such reversibility is expected. For example, even the potent muscarinic antagonist, N-methylscopolamine, with Kd of 0.2 nM, dissociates from its preferred receptor subtype with a rate constant of 0.027 ...

On October 30, President Clinton signed a bill that blocks the U.S. Sentencing Commission amendments to equalize the penalties for crack and powder cocaine from taking effect (see Congress Nixes Amendments to Sentencing Guidelines on Cocaine, Money Laundering, 58 CrL 1086, October 25, 1995).. In a statement Clinton said the U.S. is making strides in combatting crime and violence. We have to send a constant message to our children that drugs are illegal, drugs are dangerous, drugs may cost you your life -- and the penalties for dealing drugs are severe, he said. I am not going to let anyone who peddles drugs get the idea that the cost of doing business is going down.. Clinton also mentioned that he may support proposals that toughen powder cocaine sentences. When large-scale cocaine traffickers sell powder with the knowledge that it will be converted into crack, they should be punished as severely as those who distribute the crack itself.

Researchers at Yale University have been testing a vaccine against cocaine addiction. The vaccine works by binding onto cocaine in the bloodstream and preventing it from reaching the brain cells where it produces its pleasurable effect. A total of 115 cocaine- and opiate-dependent people took part in the study. The participants received five injections of either the vaccine or a placebo over a 12-week period. Those participants who finished the study with a high level of antibodies produced significantly more cocaine-free urine samples than those who had lower levels of the antibodies or who had received a placebo. The proportion of participants who reduced their cocaine use by half was 53% among those treated with the active vaccine compared to only 23% among those treated with a placebo ...
Cocaine is highly addictive, illegal, and deadly drug, which destroys virtually everyone misguided enough to try it. In many cases the only thing powerful enough to overcome the addiction is to turn ones life over to Jesus Christ. Cocaine was first used natives of South America who chewed the leaves of the coca plant, and then later isolated and purified for medical use as a local anesthetic. Cocaine is extracted from the leaves of the coca plant (Erythroxylum coca), which is indigenous to the Andean highlands of South America. Natives in this region chew or brew coca leaves into a tea for refreshment and to relieve fatigue, similar to the customs of chewing tobacco and drinking tea or coffee. Pure cocaine was first isolated in the 1880s. It was used as a local anesthetic in eye surgery. It was particularly useful in surgery of the nose and throat because of its ability to provide anesthesia, as well as to constrict blood vessels and limit bleeding. Many of the therapeutic applications of raw, ...

Cocaine-related emergency-room admissions, overdoses and requests for rehab have declined since the economy started its 2008 decline, according to data obtained by The Post. "It is sort of on a slight but steady downward trend," said Dr. Stephen Ross, director of NYUs Langone Center of Excellence on Addiction. "I treat patients in private practice. Many cocaine addicts tell me stories they dont have enough money to buy it anymore." There were 478 "accidental" deaths in which cocaine was a factor, typically overdoses, in New York City in 2006, according to the Office of the Chief Medical Examiner. That number plunged to just 274 in 2010. Powder-cocaine addicts typically shell out $60 to $80 a gram, so perhaps the high cost of blow is why also a smaller number of people - 7,693 - sought treatment for cocaine addiction in New York City last year, according to the New York State Office of Alcoholism and Substance Abuse Services. That number is a drop from 9,654 in 2008. ...

University at Buffalo researchers have identified a neural pathway that could hold a key to preventing relapse in individuals recovering from cocaine addiction. Their study focused on the activity of Activin receptors in the brain that are located in regions involved in pleasure and reward.. Published online June 1 in Nature Neuroscience, the study authored by Amy Gancarz, PhD, found that the Activin pathway controls the ability of cocaine to alter the connections between various neurons. By manipulating the activity of Activin receptors, researchers were able to change cocaine-taking behavior in animal models..
