Effects of MDMA on Emotional and Social Memories

Between-subjects, randomized, triple-blind, placebo-controlled parallel design (N=84) with three groups: MDMA at encoding, MDMA at retrieval, and placebo at both sessions.

Participants attend two sessions 48 hours apart; MDMA (1 mg/kg, oral) is administered either before encoding or before retrieval, and memory tested via surprise verbal recall and picture recognition alongside mood questionnaires.
