OBJECTIVE Studies have demonstrated verbal memory deficits associated with past year ecstasy use, although specific underlying components of these deficits are less understood. Further, prior research suggests potential gender differences in ecstasy-induced serotonergic changes. Therefore, the current study investigated whether gender moderated the relationship between ecstasy exposure and comp...

There is important preclinical evidence of long lasting neurotoxic and selective effects of ecstasy MDMA on serotonin systems in non-human primates. In humans long-term recreational use of ecstasy has been mainly associated with learning and memory impairments. The aim of the present study was to investigate the neuropsychological profile associated with ecstasy use within recreational polydrug...

Previous investigations of the subjective effects of MDMA (material sold as ecstasy) have conducted interviews and surveys of various groups of ecstasy users within particular sub-populations. This study examined subjective drug effects reported by different sub-populations of ecstasy users and explored whether the function or purpose served by using ecstasy influenced the nature of the drug ex...

Previous research has shown drug-free Ecstasy users to demonstrate selective cognitive impairment. However, there seems to be a degree of individual variation in the occurrence of such deficits. The present study aimed to assess whether these cognitive deficits are related to an awareness of problematic Ecstasy use, or to past drug dosage. Twenty regular Ecstasy users who reported experiencing ...

CONTEXT Ecstasy (street name for [+/-]-3,4-methylenedioxymethamphetamine [MDMA]) use has been associated with cognitive deficits, especially in verbal memory. However, owing to the cross-sectional and retrospective nature of currently available studies, questions remain regarding the causal direction and clinical relevance of these findings. OBJECTIVE To examine the relationship between Ecsta...

AIM To explore the role of cannabis use for the availability of ecstasy as a potential pathway to subsequent first ecstasy use. METHODS Baseline and 4-year follow-up data from a prospective-longitudinal community study of originally 3021 adolescents and young adults aged 14-24 years at baseline were assessed using the standardized M-CIDI and DSM-IV criteria. RESULTS Baseline cannabis users ...

OBJECTIVE According to previous EEG reports of indicative disturbances in Alpha and Beta activities, a systematic search for distinct EEG abnormalities in a broader population of Ecstasy users may especially corroborate the presumed specific neurotoxicity of Ecstasy in humans. METHODS 105 poly-drug consumers with former Ecstasy use and 41 persons with comparable drug history without Ecstasy u...

This paper describes the objectives and methods of The Netherlands XTC Toxicity (NeXT) study focussing on the causality, course, and clinical relevance of ecstasy neurotoxicity. Previous studies suggest that ecstasy (3,4 methylene-dioxymethamphetamine, MDMA, XTC) is toxic toward brain serotonin axons, but most of these studies have serious methodological limitations. The current study is a comb...

OBJECTIVE Previous research suggests that ecstasy users are impaired in processing visuospatial information. However, for the most part, the deficits observed appear to involve the recall and recognition of complex visual and geometric patterns. The present research sought to determine whether ecstasy use was associated with deficits in serial spatial recall and visuospatial working memory (VSW...

PURPOSE To examine the prevalence and changing patterns of ecstasy use among college students, and to determine characteristics, associated behaviors, and interests of ecstasy users. METHODS The study analyzes data regarding ecstasy use and related behaviors from the 1997 and 1999 Harvard School of Public Health College Alcohol Study. This is a survey of a nationally representative sample of ...
