Abstract

This study assessed declarative and procedural memory in ecstasy/MDMA users. Groups were: drug-naive controls (n = 24); recent ecstasy/MDMA users, who had taken ecstasy/MDMA 2–3 days before the first testing session (n = 25), and abstinent users, who had not taken ecstasy/MDMA for at least 8 days be...
