Abstract

Context Both hallucinogens and 3,4-methylenedioxymethamphetamine (MDMA or “ecstasy”) have direct agonistic effects on postsynaptic serotonin2A receptors, the key site for hallucinogenic actions. In addition, MDMA is a potent releaser and reuptake inhibitor of presynaptic serotonin.

Objective To assess the differential effects of MDMA and hallucinogen use on cerebral serotonin transporter (SERT) and serotonin2A receptor binding.

Design A positron emission tomography study of 24 young adult drug users and 21 nonusing control participants performed with carbon 11 (11C)–labeled 3-amino-4-[2-[(di(methyl)amino)methyl]phenyl]sulfanylbenzonitrile (DASB) and fluorine 18 (18F)–labeled altanserin, respectively. Scans were performed in the user group after a minimum drug abstinence period of 11 days, and the group was subdivided into hallucinogen-preferring users (n = 10) and MDMA-preferring users (n = 14).

Participants Twenty-four young adult users of MDMA and/or hallucinogenic drugs and 21 nonusing controls.
