Agony and ecstasy: a review of MDMA effects and toxicity.
BACKGROUND
Ecstasy is a recreational drug with an anecdotal reputation for safety. However, reports of adverse effects and fatalities have increased in the medical and popular press.


METHODS
Literature search and review.


RESULTS
Acute Ecstasy toxicity does not appear to be due to overdose and cannot be solely attributed to the nature of the usual ambient environment. Adverse effects include hyperthermia, seizures, cardiac arrhythmias, hepatotoxicity, hyponatraemia and many psychiatric disorders. Ecstasy causes serotonergic neurotoxicity in the brains of animals at doses close to those used by humans, but its long-term effect on the human brain is unknown.


CONCLUSIONS
Ecstasy toxicity should be considered in the differential diagnosis of a variety of medical and psychiatric conditions. Given its popularity, both the acute and the potential long-term effects are a cause for concern.
