Recreational MDMA use in Sydney: a profile of ‘Ecstasy’ users and their experiences with the drug

British Journal of Addiction August 1, 1992 Nadia Solowij, Wayne Hall, Nicole Lee 417 citations

Abstract ‘Ecstasy’ (3,4‐methylenedioxymethampketamine or MDMA) is a recreational drug that is gaining popularity world wide. There is a paucity of research regarding the ways in which Ecstasy is used and the nature of its effects. A ‘snowball’ peer network technique was used to recruit 100 users who completed anonymous questionnaires. The research revealed that Ecstasy is primarily used by...

Phenomenology and Sequelae of 3,4-Methylenedioxymethamphetamine Use

The Journal of Nervous and Mental Disease June 1, 1992 Mitchell B. Liester, Charles S. Grob, Gary Bravo et al. 130 citations

3,4-Methylenedioxymethamphetamine (MDMA) has been at the center of a debate over its potential benefits as an adjunct to psychotherapy versus its capability for neurotoxic effects and is currently classified as a Schedule 1 drug by the Drug Enforcement Administration (DEA). However, as yet, there is very little methodological data on the subjective experience of the MDMA-induced state or its...

Effects of 3,4-dihydroxymethamphetamine and 2,4,5-trihydroxymethamphetamine, two metabolites of 3,4-methylenedioxymethamphetamine, on central serotonergic and dopaminergic systems.

Journal of Pharmacology and Experimental Therapeutics May 1, 1992 Michel Johnson, I. Elayan, Glen R. Hanson et al.

The effects of 3,4-dihydroxymethamphetamine (DHM) and 2,4,5-trihydroxymethamphetamine (THM) on central serotonergic and dopaminergic systems were investigated to determine if these metabolites share the neurochemical properties of 3,4-methylenedioxymethamphetamine. THM (50-200 micrograms) or DHM (135 micrograms) was administered i.c.v. to rats; 5 days later, cortical, striatal and hippocampal...

Lasting effects of (+-)-3,4-methylenedioxymethamphetamine (MDMA) on central serotonergic neurons in nonhuman primates: neurochemical observations.

Journal of Pharmacology and Experimental Therapeutics May 1, 1992 George A. Ricaurte, A L Martello, J L Katz et al.

The purpose of this study was to assess the duration of (+-)-3,4-methylenedioxymethamphetamine's (MDMA's) effects on serotonin containing neurons in nonhuman primates. Fifteen squirrel monkeys were used: three served as controls, 12 received MDMA s.c. at a dose of 5 mg/kg twice daily for 4 consecutive days. Two weeks, 10 weeks, 8 months and 18 months after drug treatment, groups (n = 3) of...

The substituted amphetamines 3,4-methylenedioxymethamphetamine, methamphetamine, p-chloroamphetamine and fenfluramine induce 5-hydroxytryptamine release via a common mechanism blocked by fluoxetine and cocaine

European Journal of Pharmacology May 1, 1992 Urs V. Berger, Xi Gu, Efrain C. Azmitia 210 citations

The abilities of the substituted amphetamines 3,4-methylenedioxymethamphetamine (MDMA), methamphetamine, p-chloroamphetamine (PCA) and fenfluramine to induce synaptosomal [3H]serotonin (5-HT) release were compared using a novel microassay system. The rank order of release potencies was found to be (+/-)PCA congruent to (+)-fenfluramine greater than (+)-MDMA much greater than...

Stimulant effects of 3,4-methylenedioxymethamphetamine in the nucleus accumbens of rat.

European Journal of Pharmacology April 7, 1992 C W Callaway, Mark A. Geyer 35 citations

This study examined the behavioral effects in rats of intracerebral administration of S(+)-3,4-methylenedioxymethamphetamine (S-MDMA) using an automated holeboard and open-field apparatus. Administration of S-MDMA into the nucleus accumbens septi produced locomotor hyperactivity. Although the stimulant effects of S-MDMA administered systemically are antagonized by fluoxetine pretreatment, the...

The molecular mechanism of "ecstasy" [3,4-methylenedioxy-methamphetamine (MDMA)]: serotonin transporters are targets for MDMA-induced serotonin release.

Proceedings of the National Academy of Sciences March 1, 1992 Gary Rudnick, S C Wall 533 citations

MDMA ("ecstasy") has been widely reported as a drug of abuse and as a neurotoxin. This report describes the mechanism of MDMA action at serotonin transporters from plasma membranes and secretory vesicles. MDMA stimulates serotonin efflux from both types of membrane vesicle. In plasma membrane vesicles isolated from human platelets, MDMA inhibits serotonin transport and [3H]imipramine binding by...

Effects of the serotonin releasers 3,4-methylenedioxymethamphetamine (MDMA), 4-chloroamphetamine (PCA) and fenfluramine on acoustic and tactile startle reflexes in rats.

Journal of Pharmacology and Experimental Therapeutics 1992 J H Kehne, T C McCloskey, Vicki L. Taylor et al.

The substituted amphetamines 4-chloroamphetamine (PCA), 3,4-methylenedioxymethamphetamine (MDMA) and fenfluramine (FEN) share the common neurochemical action of acutely releasing central serotonin (5-HT), and yet their behavioral effects are quite different. The present study evaluated the effects of these compounds on acoustic and tactile startle reflexes. PCA and MDMA were qualitatively...

Chronic 3,4-Methylenedioxymethamphetamine (MDMA) Use: Effects on Mood and Neuropsychological Function?

The American Journal of Drug and Alcohol Abuse 1992 John H. Krystal, Lawrence H. Price, Charles Opsahl et al. 171 citations

3,4-Methylenedioxymethamphetamine (MDMA; "ecstasy") is a selective serotonin (5-HT) neurotoxin in animals. There is now preliminary evidence in humans of 5-HT deficits associated with extensive use of MDMA. In order to begin to describe the cognitive and mood effects of chronic MDMA use, nine individuals with extensive MDMA use histories were studied. Despite the absence of memory deficits on...
