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.
Drugs that inhibit the transport of neurotransmitters into axon terminals or into storage vesicles within terminals. For many transmitters, uptake determines the time course of transmitter action so inhibiting uptake prolongs the activity of the transmitter. Blocking uptake may also deplete available transmitter stores. Many clinically important drugs are uptake inhibitors although the indirect reactions of the brain rather than the acute block of uptake itself is often responsible for the therapeutic effects.

Solid-phase microextraction for cannabinoids analysis in hair and its possible application to other drugs. (1/1361)

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)

Acquisition of nicotine discrimination and discriminative stimulus effects of nicotine in rats chronically exposed to caffeine. (2/1361)

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)

Age-related reductions in [3H]WIN 35,428 binding to the dopamine transporter in nigrostriatal and mesolimbic brain regions of the fischer 344 rat. (3/1361)

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)

Characterization of [125I]RTI-121 binding to dopamine transporter in vitro. (4/1361)

AIM: To characterize the binding of [125I]3 beta-(4-iodophenyl) tropane-2 beta-carboxylic acid isopropyl ester (RTI-121) to the dopamine transporter (DAT) under physiologically relevant conditions. METHODS: [125I]RTI-121 was used to label the DAT on fresh rat striatum synaptosomal membranes in artificial cerebrospinal fluid (ACSF) at 37 degrees C. RESULTS: [125I]RTI-121 binding reached equilibrium within 3 min and remained at its plateau value for at least 9 min. The data from kinetic, saturation, and competition studies supported a one-site model for the binding of [125I]RTI-121 to the DAT. Various DAT blockers (oocaine, GBR12935, and BTCP) and substrates (dopamine and d-amphetamine) competitively inhibited the binding of [125I]RTI-121. Compared with NaPhos-KCl-NaCl assay buffer, ACSF containing Ca2+ and Mg2+ markedly increased the IC50 of DAT blockers for inhibiting [125I]RTI-121 binding with less effect on that of substrates. Various D2 receptor ligands (pergolide, quinirole, sulpiride, and l-stepholidine) had no direct effect on the binding of [125I]RTI-121. CONCLUSION: [125I]RTI-121 binding under physiologically relevant conditions fulfills the basic criteria for DAT binding assay.  (+info)

ATP-sensitive potassium channels regulate in vivo dopamine release in rat striatum. (5/1361)

ATP-sensitive K+ channels (K(ATP)) are distributed in a variety of tissues including smooth muscle, cardiac and skeletal muscle, pancreatic beta-cells and neurons. Since K(ATP) channels are present in the nigrostriatal dopamine (DA) pathway, the effect of potassium-channel modulators on the release of DA in the striatum of conscious, freely-moving rats was investigated. The extracellular concentration of DA was significantly decreased by the K(ATP)-channel opener (-)-cromakalim but not by diazoxide. (-)-Cromakalim was effective at 100 and 1000 microM concentrations, and the maximum decrease was 54% below baseline. d-Amphetamine significantly increased extracellular DA levels at the doses of 0.75 and 1.5 mg/kg, s.c. with a 770% maximum increase. (-)-Cromakalim had no effect on d-amphetamine-induced DA release, while glyburide, a K(ATP) blocker, significantly potentiated the effects of a low dose of d-amphetamine. These data indicate that K+ channels present in the nigrostriatal dopaminergic terminals modulate basal release as well as evoked release of DA.  (+info)

Comparison of effects of haloperidol administration on amphetamine-stimulated dopamine release in the rat medial prefrontal cortex and dorsal striatum. (6/1361)

Research has shown that there are important neurochemical differences between the mesocortical and mesostriatal dopamine systems. The work reported in this paper has sought to compare the regulation of dopamine release in the medial prefrontal cortex and the anterior caudate-putamen. In vivo microdialysis was used to recover dialysate fluid for subsequent assay for dopamine concentrations. The responses to D2 antagonist (haloperidol) administration, which has been shown to increase impulse-dependent dopamine release, were compared. Results demonstrated a diminished effect of systemic haloperidol administration on dopamine efflux in the prefrontal cortex. The responses to systemic administration of a nonimpulse-dependent, transporter-mediated, dopamine releaser (d-amphetamine) were also contrasted. Results again demonstrated a diminished pharmacological effect in the cortex. The potential interaction of stimulation of these two types of dopamine release was examined by coadministration of these compounds. Haloperidol pretreatment dramatically potentiated the dopamine-releasing effect of amphetamine administration. This effect was observed in both the cortex and the striatum. Subsequent work demonstrated that this effect of haloperidol was mediated by D2-like receptors in the prefrontal cortex. These results are discussed in relation to other neurochemical and neuroanatomical studies demonstrating sparse densities of dopamine transporter sites and dopamine D2 receptors in the cortex compared with the striatum. They demonstrate a functional correlate to the recently reported, largely extrasynaptic localization of dopamine transporter sites in the prefrontal cortex. Furthermore, they demonstrate the existence of cortical D2-like autoreceptors that may normally be "silent" under basal conditions.  (+info)

Female gonadal hormones differentially modulate cocaine-induced behavioral sensitization in Fischer, Lewis, and Sprague-Dawley rats. (7/1361)

Evidence suggests the existence of genetic differences in cocaine sensitization in male rats. The present study was undertaken to investigate cocaine sensitization in female rats of genetically distinct inbred (Fischer 344 and Lewis) and outbred (Sprague-Dawley) strains. All female rats were bilaterally ovariectomized and randomly assigned to one of four experimental groups: 1) estradiol benzoate group, 2) progesterone group, 3) estradiol benzoate-plus-progesterone group, and 4) ovariectomized group. Additional controls included sham-operated female rats, female rats that received a single oil injection, and female rats that received repeated oil injections. To determine gender-related differences in the acute and chronic effects of cocaine, data obtained from female rats were compared with those from strain- and weight-matched male rats. Estradiol benzoate-plus-progesterone female rats showed greater locomotor effect in response to an acute dose of cocaine and had more robust sensitization in response to repeated cocaine than did male rats. The bilateral removal of ovaries abolished cocaine sensitization. In all strains of rats studied, progesterone alone did not alter the ovariectomy-induced attenuation of cocaine behavior, but estrogen alone restored cocaine-induced behavioral sensitization. There were significant strain effects on the degree of gonadal hormonal-induced modulation of cocaine sensitization in female rats. Female Lewis rats were extremely sensitive to repeated-cocaine effects, whereas the Fischer 344 female rats showed only marginal effects. The Sprague-Dawley rats ranked intermediate in their behavioral sensitivity. The present study strongly supports the hypothesis that female rats are more sensitive to both acute and chronic behavioral effects of cocaine than are male rats and that the effects are strain dependent. It also shows that estrogen plays an important role in the increased sensitivity of female rats to cocaine sensitization. Together, these data indicate significant interactions between ovarian steroid hormones and genetic factors in cocaine-induced behavioral effects.  (+info)

Behavioral and neurochemical effects of the dopamine transporter ligand 4-chlorobenztropine alone and in combination with cocaine in vivo. (8/1361)

The current studies evaluated the novel diphenylmethoxytropane analog 4-chlorobenztropine (4-Cl-BZT), cocaine, and combinations of the two drugs for their abilities to stimulate locomotor activity, produce cocaine-like discriminative stimulus effects, and elevate extracellular dopamine (DA) in the nucleus accumbens (NAc) as measured by in vivo microdialysis. Peripherally administered cocaine was approximately twice as efficacious as 4-Cl-BZT as a locomotor stimulant and was behaviorally active at a lower dose than was 4-Cl-BZT. Cocaine also was more efficacious than 4-Cl-BZT in producing discriminative-stimulus effects in rats trained to discriminate i.p. injections of 10 mg/kg cocaine from saline. The time course of behavioral activation differed markedly between the two drugs, with much shorter onset and duration of locomotor stimulant effects for cocaine relative to 4-Cl-BZT. Similarly, i.p. cocaine (10 and 40 mg/kg) induced a pronounced, rapid, and short-lived increase in DA in the NAc, whereas i.p. 4-Cl-BZT was effective only at the higher dose and produced a more gradual, modest, and sustained (>/=2 h) elevation in accumbens DA. In contrast to i.p. administration, local infusion of 4-Cl-BZT (1-100 microM) into the NAc through the microdialysis probe elevated extracellular DA to a much greater extent than did local cocaine (nearly 2000% of baseline maximally for 4-Cl-BZT versus 400% of baseline for cocaine) and displayed a much longer duration of action than cocaine. However, when microinjected bilaterally into the NAc at 30 or 300 nmol/side, cocaine remained a more efficacious locomotor stimulant than 4-Cl-BZT. Finally, pretreatment with i.p. 4-Cl-BZT dose dependently enhanced the locomotor stimulant, discriminative stimulus effects, and NAc DA response to a subsequent low-dose i.p. cocaine challenge. The diphenylmethoxytropane analog also facilitated the emergence of stereotyped behavior and convulsions induced by high-dose cocaine. The current results demonstrate that DA transporter ligands that do not share the neurochemical and behavioral profiles of cocaine nevertheless may enhance the effects of cocaine in vivo.  (+info)

norepinephrine and dopamine reuptake inhibitors (ndris) affect norepinephrine and a different chemical in the brain, dopamine. this class of drugs includes bupropion (wellbutrin).
The long held view is cocaines pharmacological effects are mediated by monoamine reuptake inhibition. However, drugs with rapid brain penetration like sibutramine, bupropion, mazindol and tesofensine, which are equal to or more potent than cocaine as dopamine reuptake inhibitors, produce no discern …

The only medication Ive taken comparable to Reboxetine in its specificity is desipramine and even that if I recall was as an augmentation for Prozac. But neither reboxetine by itself or desipramine plus Prozac in the long term helped much. Although I got by with plain old Prozac for several years.. If it is stimulation you are looking for I recommend Provigil. For a while there they didnt know how it worked but I was looking at the wiki for it today and I guess they have discovered it is a dopamine reuptake inhibitor. Its stimulating but not like Ritalin or Amphetamine, more mild, but good for attention and energy in general. Regarding ketamine, here in the US ketamine is being used more and more it seems. There are ketamine infusion clinics popping up like mushrooms. And most of the infusion clinics put their patients on ketamine spray for maintenance after their IV infusion(s).

The monoamine uptake inhibitor BTS 74 398 effectively reversed motor deficits in MPTP-treated primates (Hansard et al., 2004), but investigation into the contribution 5-HT and noradrenaline uptake inhibition made to this effect were confounding (Hansard et al., 2002a). BTS 74 398 was found to be highly potent, but a combination of GBR 12909 with 5-HT uptake inhibition negated all the benefits afforded by the dopamine uptake inhibitor alone. Neither had there been any investigation of the dopamine receptors involved in the response. Against this background, the relative involvement of dopamine, noradrenaline, and 5-HT in motor behavior was investigated in the 6-OHDA-lesioned rat.. The selective dopamine reuptake inhibitor GBR 12909 evoked ipsilateral circling in the 6-OHDA-lesioned rat, presumably by increasing dopamine levels in the intact striatum. As previously found, neither 5-HT nor noradrenaline reuptake inhibitors produced rotational behavior over that seen following vehicle administration ...

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 ...

The maximal effects achieved by the dopamine agonists alone were also not related to the lack of GABA enhancement. For example, when given alone across a wide range of doses, methamphetamine produced significant but minimal amounts of gnawing (maximal score ,100). Amfonelic acid, on the other hand, produced greater maximal increases in gnawing (∼400) (Tirelli and Witkin, 1995). Nevertheless, THIP enhanced gnawing of both methamphetamine and amfonelic acid. Of the compounds that were not enhanced by THIP, a range of maximal effects have been demonstrated under the present testing conditions. Maximal gnawing scores for WIN 35428, bupropion, GBR 12909 and cocaine were approximately 500, 150, 200 and 350, respectively (Tirelli and Witkin, 1995).. Pharmacological or structural differences among the dopamine uptake inhibitors also appear unrelated to the differential GABA augmentation observed. Thus, although some of the compounds nonselectively block uptake of monoamines (e.g., cocaine, mazindol), ...

Mesocarb (brand names Sidnocarb, Sydnocarb) is a drug that is currently being developed for Parkinsons disease.[1] The drug was originally developed in the USSR in the 1970s [2][3] for a variety of indications including asthenia, apathy, adynamia and some clinical aspects of depression and schizophrenia.[4][5] Mesocarb was used for counteracting the sedative effects of benzodiazepine drugs,[6] increasing workload capacity and cardiovascular function,[7] treatment of ADHD and hyperactivity in children,[8][9] as a nootropic,[10] and as a drug to enhance resistance to extremely cold temperatures.[11][12] It is also listed as having antidepressant and anticonvulsant properties. The drug has been found to act as a selective dopamine reuptake inhibitor by blocking the actions of the dopamine transporter (DAT),[13][14] and lacks the dopamine release characteristic of stimulants such as dextroamphetamine.[15][16][17] It was the most selective DAT inhibitor amongst an array of other DAT inhibitors to ...
While there has been a lack of consistency in the results from different studies on cocaine withdrawal, generally, symptoms of cocaine withdrawal include: Anxiety Erratic sleep Irritability Depression Sadness Cravings for cocaine Poor concentration Lethargy These may occur anywhere from a few hours to a few weeks after the suspension of cocaine use. The symptoms can be managed by most people while at home and do not require hospitalization for detox.
Ethylphenidate (EPH) is a psychostimulant and a close analog of methylphenidate. Ethylphenidate acts as both a dopamine reuptake inhibitor and norepinephrine reuptake inhibitor, meaning it effectively boosts the levels of the norepinephrine and dopamine neurotransmitters in the brain, by binding to, and partially blocking the transporter proteins that normally remove those monoamines from the synaptic cleft. However, considering the close similarities between ethylphenidate and methylphenidate and the fact that methylphenidate, like cocaine, actually does not primarily act as a classical reuptake inhibitor, but rather as an inverse agonist at the DAT (also called a negative allosteric modulator at the DAT), it is at least very likely that ethylphenidate also primarily acts as an inverse DAT agonist instead of (or at least only secondarily) as a classical reuptake inhibitor (which could be called a competitive antagonist at the DAT using a similar terminology as negative allosteric ...

6) Antidepressants with mixed neurotransmitter results like Desyrel (trade title Trazodone) may be helpful for panic disorders, anxiety and restlessness. They are thought to work by elevating these neurotransmitter levels. 5) Norepinephrine reuptake inhibitors (NRIs) like Edronax increase norepinephrine levels only and are thought to enhance focus and motivation. 3) Norepinephrine and dopamine reuptake inhibitors (NDRIs) improve norepinephrine and dopamine ranges. 4) Norepinephrine and specific serotonergic antidepressants (NASSAs) like Tolvon and Remeron are newer medication which increase norepinephrine and serotonin but may have fewer (though different) negative effects, like drowsiness, elevated appetite, and weight acquire. Antidepressant medications are primarily based on the speculation that low ranges of the brain neurotransmitters serotonin and norepinephrine trigger depression. Only pharmaceutical companies put inventory (both actually and financially) in the idea that prescriptions ...

We show that repeated cocaine exposure in vivo broadens the timing window markedly and reduces the induction threshold of t-LTP in the mouse mPFC, rendering synapses more susceptible for potentiation. Our study highlights a novel concept in addiction biology: drugs can hijack the reward circuits by disrupting Hebbian quantitative synaptic learning rules without altering synapse strength. Our study suggests an early cocaine withdrawal period when PFC circuits may be particularly vulnerable for experience-dependent remodeling.. Several forms of cocaine-evoked synaptic plasticity have been recognized. Exposure to cocaine alters the strength of glutamatergic synapses in the VTA (Ungless et al., 2001) and NAc (Thomas et al., 2001; Pascoli et al., 2011), as well as strength of GABAergic synapses in the VTA (Liu et al., 2005) and PFC (Lu et al., 2010). Cocaine also alters AMPAR composition at NAc and VTA excitatory synapses (Bellone and Lüscher, 2006; Conrad et al., 2008), characterized by the ...

This study investigated the role of prolonged cocaine withdrawal in the development of glutamatergic plasticity in the accumbens by performing behavioral, morphological, and electrophysiological analysis to the same set of animals to correlate functional with morphological changes. These parallel studies are important in light of previous studies that indicated that some parameters of the cocaine treatment would affect the outcome of behavioral and cellular studies, such as home cage versus novel cage injections or the presence of a challenge cocaine injection (Li et al., 2004; Boudreau et al., 2007; Kourrich et al., 2007). The results showed that functional and morphological changes can develop right after a long cocaine treatment without the need for withdrawal. These synaptic changes include increased frequency of AMPA-mediated mEPSC, enhanced AMPA/NMDA ratio of the evoked responses, higher density of dendritic spines, and larger spine heads in D1(+) MSNs of the NAc. Although these changes ...

Chronic cocaine - Cocaine-paired (conditioned place preference) vs. Control (saline or cocaine-non-paired) DNA microarray All genes on microarray presented After the pre-conditioning phase where animals were allowed access to either compartment for 15 minutes for 4 consecutive days, the conditioning phase for the cocaine-paired groups and cocaine non-paired groups began, consisting of eight subsequent daily sessions. For both groups, cocaine (10 mg / kg) or saline injections were administered on alternate days. For the cocaine-paired groups, rats were immediately placed in one of the two compartments for 30 min with the door in place restricting a z transformation followed by z test and anova followed by Student-Newman-Keuls post hoc test. Gene expression profile was assessed 24 h after the last conditioning session that corresponded to 48 h after last cocaine exposure, when drug has been eliminated from the body and transient transcriptional changes are likely to be minimal. Therefore, changes ...
Cocaine addiction has become a major problem and epidemic in this country. Thousands of individuals and families are negatively affected by the use and abuse of cocaine every year. Cocaine is expensive, but individuals who use the drug to enhance their nightlife experience or work longer hours certainly are not afraid of long term consequences and repercussions. But as the years went on, studies began to find that long-term cocaine users were at risk for heart disease, heart failure, liver problems and other serious concerns. In addition, the financial burden that cocaine puts on families often lead to broken homes and lost trust. It is apparent that the need for cocaine rehab is immediate and must be confronted and addressed as soon as possible. Cocaine rehab refers to the process of helping an individual overcome their physical and psychological addiction to cocaine. This is accomplished through detoxification, individual counseling and cognitive therapy. In addition, a recovering cocaine ...

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 ...
