Currently there are no medications approved for the treatment of methamphetamine addiction. Bupropion is an antidepressant that is approved by the Food and Drug Administration (FDA) for the treatment of depression and for cigarette smoking cessation but is not approved by the FDA for the treatment of methamphetamine addiction. Preliminary research studies suggest that bupropion may help people receiving treatment for methamphetamine addiction to reduce or to stop their methamphetamine use. But results of these studies also suggest that bupropion may help certain groups of patients more than others, such as men versus women and light versus heavy methamphetamine users, although the reasons for this difference are not known. One possibility is that a persons genetic make up may influence whether or not they respond to treatment with bupropion for methamphetamine addiction.. The purpose of the study is to determine if bupropion is can help people reduce or stop their methamphetamine use and to ...
Methamphetamine is a drug that causes excess amounts of the neurotransmitters dopamine and norepinephrine to be released into the brain. This overload produces unusual alertness and feelings of elation. When the body undergoes methamphetamine withdrawal, it experiences a reduction in dopamine and norepinephrine. Bupropion is an antidepressant used for the treatment of depression and smoking cessation. Because it functions by increasing the release of dopamine and norepinephrine in the brain, bupropion is likely to decrease the negative effects of methamphetamine withdrawal. The purpose of this study is to evaluate the efficacy of bupropion combined with contingency management (CM) and cognitive behavioral counseling (CBT) as a means of treating methamphetamine dependence.. An initial 2-week screening process will involve participants providing urine samples and completing physical and psychological assessments. If deemed eligible for the remainder of this double-blind study, participants will be ...

Memory is a complex of systems by which an organism registers, stores and retrieves exposure to an event or experience. Literature purports that methamphetamine users and dependents have been found to exhibits signs of memory impairment. The aim of the research was to establish the possible existence of significant differences in memory in current methamphetamine users, recovering methamphetamine users, and a matched drug naïve control group. Cognitive functioning was assessed via a neurocognitive test battery that examined the memory of 14 current methamphetamine users, 17 recovering methamphetamine addicts, and 18 drug naïve control participants who were matched according to the demographic variables of age, gender and educational status. The results indicated that recovering methamphetamine users experienced the greatest impairment in memory in comparison to both the control group and current users of methamphetamine. The current users of methamphetamine also experienced some impairment in memory

Many people that struggle with Methamphetamine Abuse care for nothing but their high, so their unaware of the deadly Methamphetamine Abuse Symptoms.
Methamphetamine use has increased substantially in the United States since the 1990s. Few studies have examined the healthcare service needs of women who use methamphetamine. This study describes unmet medical needs in a community-based sample of women who use methamphetamine in San Francisco, CA. Women who use methamphetamine were recruited in San Francisco and participated in a computer-assisted survey (N = 298 HIV-negative women).
The rise in methamphetamine use among gay and bisexual men in urban centers over the past 10 years has resulted in a greater understanding of the biologic, psychologic, and cultural dimensions of the problem, as well as the development of specific treatments for this patient population. Culturally informed individual counseling and group psychotherapy, based on the principles of motivational interviewing and organized around the Matrix Model, appear to be most effective in the outpatient management of this difficult illness. Pharmacotherapy is limited to the treatment of co-occurring psychiatric disorders.. ...
This ease in the manufacture of methamphetamine has led to the mushrooming of clandestine laboratories for the manufacture of methamphetamine. Estimates in 2006 put the number of such clandestine laboratories manufacturing illegal methamphetamine in the United States of America was more than 6,435, based on the number of laboratory incidents. Most of these laboratories are located in California or in Mexico (OVERVIEW OF METH).According to the National Institute of Drug Abuse (NIDA), in the recent past, there has been an increase in methamphetamine abuse and the problems associated with it in the United States of America. This is reflected in the four-fold increase in the number of people seeking treatment for methamphetamine abuse over the last decade, and the fifty percent increase in emergency calls owing to methamphetamine abuse, over a seven-year period from 1995 to 2002 (Volkow, 2006).Addiction to drugs is a disease of the brain that involves genetic, psychological and social factors.

Last decade, positive drug tests among U.S. workers for methamphetamine had started to drop. That trend may be reversing, with positive rates dramatically higher in some states compared to others. The new statistics come from Quest Diagnostics annual report on U.S. worker drug use, based on more than six million urine tests collected from January-December 2010.. Positives for methamphetamine use in the U.S. general workforce dropped dramatically from 0.18% in 2006 to 0.11% in 2008. However, the rate remained the same in 2009 and 2010 at 0.10%.. Dr. Steven Shoptaw, a researcher who studies therapies for methamphetamine dependence, says, Ive worked with patients who, paralyzed by the recession and juggling multiple jobs and family responsibilities, started using methamphetamine for its functional stimulant benefit.. Shoptaw notes that, even when its used as a stimulant by people who work more than one job, meth can wreak havoc on their judgment.. For these sort of people, we now provide ...
In the study published in Addiction Biology, researchers from three Taiwanese institutions explored the potential role of declining levels of a protein called BDNF in promoting the brain damage found in chronic methamphetamine abusers and addicts. Under normal circumstances, BDNF provides the brain with critical protection by helping nerve cells grow, reach maturity and stay in good working order. In addition, the protein plays an essential role in basic brain functionality by supporting the chemical and physical adaptations required for learning new information and storing that information in memory.. For their study, the researchers recruited 59 people diagnosed with methamphetamine abuse, as well as a second group of 59 generally healthy individuals who did not use the drug. The methamphetamine abusers had stopped actively taking the drug and were in the early stages of withdrawal. Over a period of three weeks, the researchers used blood tests to measure the levels of BDNF in both groups of ...
Why people with attention-deficit/hyperactivity disorder (ADHD) are at greater risk of substance dependence, particularly methamphetamine dependence, and have greater difficulty overcoming their addiction is the subject of a new study by researchers at the UC Davis MIND Institute.
Objective: To investigate whether methamphetamine use is associated with sexual risk behavior among adolescents. Method: A cross-sectional survey of 1,561 male and female high school students in Cape Town (mean age 14.9 years) was conducted using items from the Problem Oriented Screening Instrument for Teenagers (POSIT) HIV Risk Scale. Results: Nine percent of the students had tried methamphetamine and 30% of male and 17% of female students reported sexual debut. Multinomial logistic regression analyses showed that methamphetamine use in the past year was significantly associated with being in a higher HIV/STI risk category (RRR = 2.1, 95% CI: 1.10-4.03, p & 0.05). Conclusions: Methamphetamine use, coupled with a high HIV prevalence in South Africa, raises serious cause for concern about the potential for methamphetamine to further exacerbate the prevalence and spread of HIV in Cape Town. © 2012 Taylor and Francis Group, LLC.. ...

Methamphetamine (METH) use, especially in females, has become a growing public health concern in China. In this study, we aimed to characterize the factors that contributed to drug craving in female METH users under isolated compulsory detoxification. We characterized factors contributing to craving such as duration of detoxification, history of drug use and self-reported mood state. Subjects (N=113) undergoing a 1- to 3-year METH detoxification program were recruited from the Zhejiang Compulsory Detoxification Center for Women. The Questionnaire of METH-use Urge (QMU) was used to evaluate the level of craving for METH. The Abbreviate Profile of Mood States (A-POMS) was applied as an assessment for the negative mood disturbances. The participants were at a mean age of 25.2, primarily lowly educated and unemployed, and single. Smoking was the only route of METH administration at an average dose of 0.5 g/day, and 4 times/week. The reported craving level was positively correlated with the negative mood

TY - JOUR. T1 - SB 206553, a putative 5-HT2C inverse agonist, attenuates methamphetamine-seeking in rats. AU - Graves, Steven M.. AU - Napier, T. C.. PY - 2012/6/14. Y1 - 2012/6/14. N2 - Background: Methamphetamine (meth) dependence presents a substantial socioeconomic burden. Despite the need, there is no FDA-approved pharmacotherapy for psychostimulant dependence. We consider 5-HT2C receptors as viable therapeutic targets. We recently revealed that the atypical antidepressant, mirtazapine, attenuates meth-seeking in a rodent model of human substance abuse. Mirtazapine historically has been considered to be an antagonist at 5-HT2C receptors, but more recently shown to exhibit inverse agonism at constitutively active 5-HT2C receptors. To help distinguish the roles for antagonism vs. inverse agonism, here we explored the ability of a more selective 5-HT2C inverse agonist, SB 206553 to attenuate meth-seeking behavior, and compared its effects to those obtained with 5-HT2C antagonists, SDZ Ser 082 ...

People who abused methamphetamine or other amphetamine-like stimulants were more likely to develop Parkinsons disease than those who did not, in a new study from the Centre for Addiction and Mental Health (CAMH).. The researchers examined almost 300,000 hospital records from California covering 16 years. Patients admitted to hospital for methamphetamine or amphetamine-use disorders had a 76 per cent higher risk of developing Parkinsons disease compared to those with no disorder.. Globally, methamphetamine and similar stimulants are the second most commonly used class of illicit drugs.. This study provides evidence of this association for the first time, even though it has been suspected for 30 years, said lead researcher Dr. Russell Callaghan, a scientist with CAMH. Parkinsons disease is caused by a deficiency in the brains ability to produce a chemical called dopamine. Because animal studies have shown that methamphetamine damages dopamine-producing areas in the brain, scientists have ...

RGS9-2 is highly expressed in the striatum and plays a role in modulating dopaminergic receptor-mediated signaling cascades. Previous studies suggested that the RGS9 gene might contribute to the susceptibility to psychotic diseases. Therefore, we investigated the association between the RGS9 gene and two related dopamine psychoses, schizophrenia and methamphetamine use disorders. The subjects comprised 487 patients of schizophrenia and 464 age- and sex-matched healthy controls and 220 patients of methamphetamine use disorder and 289 controls. ...
A new study funded by the National Institute on Drug Abuse (NIDA) documents the high rates and unique patterns of dental decay and gum disease in people who use the illicit drug methamphetamine. The large study of 571 methamphetamine users found that 96 percent had experienced dental cavities and 58 percent had untreated tooth decay. Only 23 percent retained all of their natural teeth, compared to a tooth retention rate of 48 percent among the U.S. general population. The study was conducted by investigators at the University of California, Los Angeles (UCLA).. The study found that adults reporting moderate or heavy methamphetamine use were twice as likely to have untreated dental cavities than were light users (less than 10 days of use over the past month). Older subjects (ages 30+), women, and current cigarette smokers were disproportionately affected by dental and periodontal disease. In addition, a significant percentage of participants (40 percent) indicated they were often self-conscious ...
Methamphetamine is a stimulant commonly abused in many parts of the United States. Most methamphetamine users are white men 18 to 25 years of age, but the highest usage rates have been found in native Hawaiians, persons of more than one race, Native Americans, and men who have sex with men. Methamphetamine use produces a rapid, pleasurable rush followed by euphoria, heightened attention, and increased energy. Possible adverse effects include myocardial infarction, stroke, seizures, rhabdomyolysis, cardiomyopathy, psychosis, and death. Chronic methamphetamine use is associated with neurologic and psychiatric symptoms and changes in physical appearance. High-risk sexual activity and transmission of human immunodeficiency virus are also associated with methamphetamine use. Use of methamphetamine in women who are pregnant can cause placental abruption, intrauterine growth retardation, and preterm birth, and there can be adverse consequences in children exposed to the drug.

Prenatal methamphetamine exposure (PME) is the exposure of a fetus to methamphetamine when a woman uses the drug during her pregnancy. Methamphetamine (MA) has shown increasing popularity in the past two decades among women of childbearing age. Methamphetamine is second only to cannabis as the most widely used illegal drug, which may be because it is relatively cheap and easy to manufacture. Yet, to this date, the effects of PME on the developing fetus have not been well characterized and even less is known regarding the effects on development in childhood. Although few studies have established a pattern of MA use in pregnant users, it is important that researchers seek to determine this pattern to examine a possible dose-response relationship between MA use and neonatal outcomes. The recent increase in MA use in the United States, particularly in the South and Midwest, highlights the need for a better understanding of the short-term and long-term effects of MA use during pregnancy upon newborns ...
Importance Methamphetamine use is increasingly prevalent and associated with HIV transmission. A previous phase 2a study of mirtazapine demonstrated reductions in methamphetamine use and sexual risk behaviors among men who have sex with men.. Objective To determine the efficacy of mirtazapine for treatment of methamphetamine use disorder and reduction in HIV risk behaviors.. Design, Setting, and Participants This double-blind randomized clinical trial of mirtazapine vs placebo took place from August 2013 to September 2017 in an outpatient research clinic in San Francisco, California. Participants were community-recruited adults who were sexually active; cisgender men, transgender men, and transgender women who (1) had sex with men, (2) had methamphetamine use disorder, and (3) were actively using methamphetamine were eligible. Participants were randomized to receive the study drug or placebo for 24 weeks, with 12 more weeks of follow-up. Data analysis took place from February to June ...
Methamphetamine can increase the release and even block the reuptake of the brain chemical dopamine. This leads to higher levels of dopamine in the brain which is common for drug abusers. Dopamine is responsible for reward, experience of pleasure, motivation and motor function. Since methamphetamine has the ability to release dopamine quickly in the brain, the reward sections of the brain experience an intense euphoria or a rush once the drug has been smoked, snorted, or injected into the body.. Using methamphetamine for a long period of time can significantly change how the brain is able to function. These functions can include reduced motor skills and impaired verbal learning. In other studies conducted, it also shows that chronic methamphetamine abusers have severe structural and even functional changes in the brain; in the memory and emotion areas. This is why many of the abusers of the drug have problems with emotional and cognitive situations.. Using methamphetamine for an extended period ...

A few studies have also examined the persistent neurochemical impact of METH self-administration in rats, but with variable results. These latter studies are important because: 1) they have relevance to the study of METH abuse; and 2) the effects of noncontingent METH treatment do not necessarily predict effects of ...
Methamphetamine is often a white or light brown crystalline powder. It can also be in liquid form. If you find it in your home, then that has to be the most obvious sign that someone is abusing it. Still, most adults will try to hide their use of illicit drugs, so getting this evidence might not be so easy.. If you fear that someone you love is abusing the drug-or is already addicted to it-there are a couple of signs you can look out for. If you find small pieces of crumpled aluminum foil lying around your house, thats another indication of drug abuse.. But meth abusers often do not sleep for long periods of time. They take meth until they run out, or until they are unable to maintain consciousness. They will rapidly and drastically lose their weight, becoming and appearing malnourished. This is an effect of methamphetamine abuse, wherein the user loses their appetite.. The drug is a stimulant, so the user will appear euphoric or active. They may also be more nervous or anxious for no ...

They enrolled 412 mother and infant pairs at four sites and identified participants as ...
Alcohol and meth have different functions. Alcohol is a sedative - a downer - and works as a central nervous system depressant, also called a CNS depressant. Its effects include nausea, impaired thinking, and slowed cardiovascular functioning. When consumed in large quantities, alcohol can cause dramatic mood swings, slurred speech, loss of motor skills coordination, and alcohol poisoning.. Methamphetamine, or meth, is a stimulant - an upper - and considered one of the most potent of its kind. It stimulates the central nervous system, leading to the occurrence of high blood pressure, increased energy, amplified heart rate, and euphoria. Medically, methamphetamine is an FDA-approved medication for treating ADHD and exogenous obesity in both children and adults.. Being addicted to methamphetamine and alcohol can increase the risk for alcohol poisoning. According to the New Research on Methamphetamine Abuse, ethanol or alcohol attenuates the effects of methamphetamine and slows down the metabolism ...

Case report. Mr A, a 38-year-old single man, was admitted to the emergency setting of Iran Educational and Therapeutic Center of Psychiatry because of his suicide attempt in February 2009. He reported hearing voices who ordered him to kill himself. The patient started methamphetamine use in March 2008 at 1 pack/d (a pack is equal to one-tenth of a gram) and gradually increased his dose up to 2.5 packs before his admission. Four months after beginning to use the drug, he began to experience auditory hallucination and persecutory delusion. Initially, the hallucinations comprised voices of 1 or 2 people commanding or insulting him. Gradually, the number and frequency of voices increased, and the voices did not leave the patient even for a moment. He tried to self-medicate by increasing the dose of methamphetamine, which would bring him a temporary relief for 1 or 2 hours; after which, the voices would return more vigorously. Therefore, he might use the drug up to 4 or 5 times a day.. A ...

WEDNESDAY, Aug. 21, 2019 (American Heart Association News) -- Although frequently overshadowed by the opioid epidemic, surging methamphetamine use nationally and around the world has fueled a chilling crisis of its own, according to a new report.. The result is a significant increase in meth-related deaths from unique cardiovascular consequences that researchers are trying to understand.. Methamphetamines can cause blood vessels to constrict and spasm, dangerous spikes in blood pressure, and the rewiring of the hearts electrical system, among other potentially fatal heart-related problems.. Cardiovascular disease represents the second-leading cause of death among methamphetamine abusers following only accidental overdose, according to the report published Wednesday in the American Heart Associations journal Arteriosclerosis, Thrombosis, and Vascular Biology.. The report reviews current research on methamphetamine and the drugs effect on heart disease and stroke. It discusses potential ...
Methamphetamine (Meth) abuse has reached epidemic proportions in many countries and can induce psychotic episodes mimicking the clinical profile of schizophrenia. Brain-derived neurotrophic factor (BDNF) is implicated in both Meth effects and schizophrenia. We therefore studied the long-term effects of chronic Meth exposure in transgenic mice engineered to harbor the human BDNFVal66Met polymorphism expressed via endogenous mouse promoters. These mice were chronically treated with an escalating Meth regime during late adolescence. At least 4 weeks later, all hBDNFVal66Met Meth-treated mice exhibited sensitization confirming persistent behavioral effects of Meth. We used high-resolution quantitative mass spectrometry-based proteomics to biochemically map the long-term effects of Meth within the brain, resulting in the unbiased detection of 4808 proteins across the mesocorticolimbic circuitry. Meth differentially altered dopamine signaling markers (e.g., Dat, Comt, and Th) between hBDNFVal/Val and hBDNFMet
KOKOMO, Ind. - A teenager who died in a pursuit and crash last month in Kokomo was high on methamphetamine, investigators say. The Howard County Coroner
Wasp spray is becoming an increasingly popular alternative to methamphetamine, posing a whole new set of health risks, law enforcement officials say. The problem has become particularly bad in West Virginia, according to TV station KIRO. The wasp spray is inhaled or injected, providing a rush similar to the one methamphetamine users experience. Sometimes it is used alone, while other times it is used alongside methamphetamine to intensify effects. At least three overdoses have been reported so
Recent studies and research shows that People who use methamphetamine are almost five times more likely to have a stroke caused by a bleed in the brain, many of which are fatal. We can add stroke to the list of terrible and devastating things that methamphetamine does, says Damian Zuloaga, of the University at Albany, New York.. Beyond the signature tooth decay known as meth mouth, methamphetamine also increases heart rate and blood pressure, and can trigger heart attacks. The drug can lead to psychosis, and has been linked to anxiety disorders, depression, and problems with movement similar to those seen in Parkinsons disease.. A handful of studies have also linked methamphetamine use to strokes. To explore further, Julia Lappin and her colleagues at the Australian National Drug and Alcohol Research Centre in Sydney sifted through published research on the topic.. The team specifically looked for research into people under the age of 45 - a group less likely to be affected by age-related ...
The problem of methamphetamine use in todays society is an ever growing problem. Women of childbearing age are among this group, leading to an increasing number of children with prenatal methamphetamine exposure.. Christine Cloak, Ph.D., of the University of Hawaii, and colleagues findings are reported online in Neurology. The researchers did MRI scans on 29 methamphetamine-exposed children 3 to 4 years old, recruited from local hospitals, drug rehabilitation centers, and the community. Using detailed interviews of the mothers, the cumulative gestational methamphetamine exposure reported averaged 58 g over 2.5 trimesters, but varied widely.. Methamphetamine has been shown to cross the placenta and impact overall fetal growth. The drug is known to act on dopamine receptors that regulate corticogenesis and are present in the brain as early as the first trimester. It also affects other catecholamine systems involved in brain development.. Cloak and colleagues found that prenatal exposure to meth ...

Mexican criminal groups have replaced traditional Asian criminal groups as the primary transporters of methamphetamine. Mexican criminal groups are the primary transporters of Mexico-produced methamphetamine as well as methamphetamine produced in California. Law enforcement officials report that Mexican criminal groups transport methamphetamine into Hawaii from the West Coast, primarily California. Mexican criminal groups transport both powdered and crystal methamphetamine. Some powdered methamphetamine is converted to crystal methamphetamine in Mexico and on the West Coast for transportation to Hawaii.. Traditional Asian transporters of crystal methamphetamine--primarily Korean, Japanese, Filipino, and Vietnamese criminal groups--also transport the drug into Hawaii, but to a lesser extent than during the mid-1980s to early 1990s. In the early 1990s law enforcement authorities in Hawaii dismantled several large Asian, primarily Korean, criminal groups that dominated the transportation of crystal ...

Eighteen rats were implanted with intravenous (IV) catheters and bilateral AcbSh electrodes and subsequently underwent daily sessions in 2-lever (active/methamphetamine and inactive/no reward) operant chambers to establish IV methamphetamine self-administration. After stable responding was achieved, 3 hours of DBS or sham treatment was administered (sham: 0 µA, n = 8; active: 200 µA, n = 10) in a separate nondrug environment prior to the daily operant sessions for 5 consecutive days. Immediately following each DBS/sham treatment, rats were placed in the operant chambers to examine the effects of remote stimulation on methamphetamine intake. After the 5 days of therapy were finished, rats reestablished a posttreatment baseline, followed by extinction training, abstinence, and 1 day of relapse testing to assess methamphetamine-seeking behavior. ...
Methamphetamine exists as two enantiomers. The S(+) form, which is also called d methamphetamine, is an ingredient in a few legitimate pharmaceutical products available only by prescription, and can be illicitly synthesized from (-) ephedrine or (+) pseudoephedrine. The S(+) or d form of methamphetamine is generally considered a drug of abuse. On the other hand, the R(-) form, which is also called l-desoxyephedrine or l methamphetamine, is the active ingredient in Vicks inhalers, is a metabolite of the anti-Parkinson drug Selegiline, and is not a drug of abuse. When a specimen gives a confirmed positive result for methamphetamine, this test can be ordered. This test separates the enantiomers and will provide percentage-based information to help determine the source of methamphetamine in the specimen. Note that this test does not provide quantitations; it only provides the percentage(s) of each methamphetamine found in the urine. The urine should be previously tested for methamphetamine and ...
Methamphetamine, generally described as meth, is a highly-addictive neurotoxic energizer that is commonly described as one of the most hazardous medication on earth, due to the broad schedule, simplicity of usage, and also capacity to produce the medicine from normal home products. Most often, methamphetamine comes in two forms, Crystal Meth and also powdered meth, both generate comparable impacts on the customer.. Meth generates a false sense of well-being and joy. It gives the user a thrill, and an increase in feelings of power, confidence, and also wakefulness. These results generally last six to eight hrs, however can be sustained for upwards of twelve hrs.. Methamphetamine is merely and also cheaply made using different family products in about two days- start to complete. The key component in methamphetamine is pseudoephedrine or ephedrine, both of which are discovered in a wide variety of over the counter chilly treatments.. ...

N2 - In Parkinsons disease, depletion of dopamine in the striatum leads to various symptoms such as tremor, rigidity and akinesia. Methamphetamine use has significantly increased in USA and around the world and there are several reports showing that its long-term use increases the risk for dopamine depletion. However, the toxic mechanisms of methamphetamine are not well understood. This study was undertaken to gain greater mechanistic understanding of the toxicity induced by methamphetamine. We evaluated the effect of methamphetamine on the generation of reactive oxygen species, mitochondrial ...
The negative impacts of the illicit drug trade touch every society in the world. The World Drug Report for 2005 estimates that 200 million people, or 5% of the global population age 15-64, have consumed illicit drugs at least once in the last 12 months. The UN Office on Drugs and Crime (UNODC) estimates its worldwide retail value to be $321bn. It impacts almost every level of human security from individual health, to safety and social welfare. Its consequences are especially devastating for countries with limited resources available to fight against it.. The World Drug Report 2007 places the UK in joint first place with Denmark (out of 30 European countries) for amphetamine use and in fifth place for ecstasy use. The report states that although still tiny compared to amphetamine, the amount of methamphetamine seized in Europe rose more than four-fold between 2000 and 2005.. Chemical Dependency. Chemical dependency has many faces and takes many forms, including the use of depressants, stimulants, ...
