Methamphetamine abuse is a significant public health concern. Although widely studied in laboratory animals, little is known about the abuse-related behavioral effects of methamphetamine relative to other abused stimulants in controlled laboratory settings in humans. The aim of this study was to examine the discriminative stimulus, subject-rated, performance, and cardiovascular effects of metha...

conclusions the findings of the study showed that, compared with the opiate users, methamphetamine users are younger, more likely to be single, and less likely to have received treatment. we recommend that policymakers should not only design preventive programs for improving the level of knowledge about stimulant use, but also prepare treatment plans and facilities for this newly emerged substa...

In both humans and laboratory animals, the reports of cognitive effects following acute amphetamine (Amph) administration are mixed and depend, for example, on the timing of administration (e.g. before or after task acquisition) and/or on the memory model used. Besides its cognitive effects, Amph produces other important behavioural effects, including alterations in anxiety and general activity...

Abuse of monoamine oxidase inhibitors is not common but there are a few cases of addiction in the literature. Most of these patients had an additional diagnosis, either history of past drug abuse or personality disorder and MAOI withdrawal symptoms have been reported. We encountered three patients who received MAOI under psychiatric care. They were all self medicated by increasing the doses on ...

introduction:amphetamines are central nervous system (cns) stimulant substances and amphetamine abuse is considered a growing problem in our country. previous studies revealed destructive effects of amphetamines on metabolism, perfusion and structure of brain. the aim of current study was evaluating regional cerebral blood flow (rcbf) disturbances in methamphetamine (ma) abusers using brain per...

The methylenedioxy-derivatives of amphetamine and methamphetamine represent the largest group of designer drugs. The most frequently used compounds are 3,4-methylenedioxy-methamphetamine (MDMA-ecstasy) and 3,4-methylenedioxy-amphetamine (MDA), first synthesised in 1910 (MDA) and 1914 (MDMA), respectively, to be used as an appetite suppressant. At the end of the 1960s, non-medical (recreational)...

Undergraduate students were recruited to participate in an online survey to report their use of amphetamine stimulants and other drugs. Significant differences were found between students reporting (n=79; 4.0%) and not reporting (n=1,897; 96%) amphetamine-stimulant use in the past month - in terms of race/ethnicity, class standing, residence, health symptoms, self-health report - in addition to...

Methand other amphetamines currently present major drug-abuse concerns. However, the demonstration and study of abuse-related behaviors expressed in animal models is expensive and time-consuming. We previously reported a novel model of conditioned place preference (CPP), which is a standard tool in abuse research, in invertebrates (planarians). In the present study, planarians were tested for l...
