(+/-)-3,4-methylenedioxymethamphetamine (MDMA, ecstasy) is often taken recreationally with ethanol (EtOH). In rats, EtOH may potentiate MDMA-induced hyperactivity, but attenuate hyperthermia. Experiment 1 compared the interactions between EtOH (1.5 g/kg) and MDMA (6.6 mg/kg) with EtOH + cocaine (COCA; 10 mg/kg) and EtOH + amphetamine (AMPH; 1 mg/kg) on locomotor activity and thermoregulation....
3,4‐Methylenedioxymethamphetamine (MDMA) is an amphetamine derivative with increasingly widespread abuse. MDMA has been difficult to classify as a stimulant or hallucinogen because it shares effects with both drug classes. Furthermore, racemic MDMA is composed of two isomers that vary in terms of behavioral effects rather than simple potency differences. Specifically, the R(−) isomer of MDMA...
Previously it has been shown that MDMA causes memory impairment during daytime testing. However, MDMA is usually taken in the evening or during the night. In addition, it is known that sleep deprivation also causes memory impairment. The present study aimed to assess whether evening doses of MDMA added to, or interacted with the memory impairment due to sleep deprivation. Fourteen healthy...
Co-administration of MDMA and ethanol did not exacerbate the effects of either drug alone. Although the impairment of performance by all drug conditions was relatively moderate, all induced significant impairment of cognitive function.
Background: Ecstasy use has increasingly become popular among young adults, many of whom view it as a safe drug with no or limited negative social and health consequences. In this paper, we explore the perceptions of ecstasy users about its recreational use as well as regarding the normalisation of use. Methods: The study participants were recruited using targeted and theoretical sampling. To...

The mechanism of MDMA (3,4-methylenedioxymethamphetamine)-induced toxicity is believed to be, in part, due to enhanced oxidative stress. As MDMA is eliminated via the kidney, the aim of this study was to investigate whether MDMA created conditions of oxidative stress within rat kidney. Adult male Wistar rats were divided into three groups, control treatment (water), acute MDMA administration...
Ecstasy (3,4 methylenedioxymethamphetamine, or MDMA) is a recreational drug widely used among young people in discos or rave parties (1,2). MDMA is taken because it gives a feeling of euphoria, enhances energy and sociability, and heightens sensations and sexual arousal. However, several side effects have been described: headache, nausea, anorexia, xerostomia, insomnia, myalgia, trismus, and...
The chiral nature of the MDMA molecule gives rise to two enantiomers, each of which is biologically active. This review attempts to cover the author's research into the in vivo effects of MDMA and its enantiomers, as well as other relevant publications which pertain to this topic. No particular differences between the capacities of racemic MDMA and its enantiomers to maintain behavior were...
3,4-methylenedioxymethamphetamine (MDMA), more commonly known as 'ecstasy' or XTC, is frequently used by young adults in the major cities. Therefore, it is likely that dentists might be confronted with individuals who use ecstasy. This review describes systemic and oral effects of ecstasy. Life-threatening complications include hyperthermia, hyponatraemia and liver failure. In addition,...
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...
