The lowering of serotonin for a period following MDMA use could account for the increases in both self-rated and objective measures of aggression previously found in ecstasy users several days after taking the drug. There is some evidence of gender differences in the acute, sub-acute and long-term effects of MDMA use, and given that gender differences have been found in aggression, it is...

All previous studies of the sub-acute effects of ecstasy have failed to adequately control for group differences in psychopathology and past and concurrent substance use. The present study was designed to avoid these limitations. At an initial pre-drug baseline, a sample of 38 regular ecstasy users provided full substance histories and completed measures of personality and self-reported...

This review of the literature aims to identify the acute effects of MDMA (ecstasy) in healthy volunteers. The wide range of relevant but methodologically diverse tests was .rst grouped into clusters to allow an evaluation of tests that would otherwise have been excluded due to their low frequency of utilization. The following three types of tests were evaluated: (1) functional tests quantifying...

The term "date rape drug" has traditionally been applied by the media to powerful sedatives, such as gamma hydroxybutyrate (GHB) and flunitrazepam (Rohypnol), which can render a person unconscious and hence unable to resist and/or recall an assault. However, some law enforcement agents and others have recently obtained convictions by arguing that the empathy-generating and sensual effects of...

Users of ecstasy (3,4-methylenedioxymethamphetamine; MDMA) may be at risk of developing MDMA-induced injury to the serotonin (5-HT) system. Previously, there were no methods available for directly evaluating the neurotoxic effects of MDMA in the living human brain. However, development of in vivoneuroimaging tools have begun to provide insights into the effects of ecstasy on the human brain....

Many recreational ecstasy/MDMA users display neuropsychobiological de.cits, whereas others remain problem free. This review will investigate some of the drug and non-drug factors which in.uence the occurrence of these de.cits. Acute and chronic MDMA usage are both important. Intensive use within a session is often associated with more problems. In term of lifetime usage, novice users generally...

Repeated ecstasy (MDMA) use is reported to impair cognition and cause increased feelings of depression and anxiety. Yet, many relevant studies have failed to control for use of drugs other than MDMA, especially marijuana (THC). To address these confounding effects we compared behavioural performance of 11 MDMA/THC users, 15 THC users and 15 non-drug users matched for age and intellect. We...

Although 3,4-methylenedioxymethamphetamine (MDMA, ecstasy) is a known serotonergic neurotoxin in different animal species, there is to date no conclusive evidence of its neurotoxicity in humans. MDMA use was associated with impairments of psychological well-being, verbal memory and altered serotonergic functioning in a number of crosssectional studies. Due to inherent methodological...

The popular dance drug ecstasy (3,4-methylenedioxymethamphetamine -- MDMA) is neurotoxic upon central serotonergic neurons in laboratory animals and possibly also in humans. In recent years, several studies reported alterations of serotonergic transmission and neuropsychiatric abnormalities in ecstasy users which might be related to MDMA-induced neurotoxic brain damage. To date, the most...

ABSTRACT Background The popular dance drug ecstasy (3,4‐methylenedioxymethamphetamine: MDMA and some analogues) causes selective and persistent neurotoxic damage of central serotonergic neurones in laboratory animals. Serotonin plays a role in numerous functional systems in the central nervous system (CNS). Consequently, various abnormalities including psychiatric, vegetative, neuroendocrine...
