Randomized, triple-blind, crossover study (n=22) testing single oral MDMA 1.5 mg/kg versus placebo on affective touch responses across a range of autistic traits.
Randomized, triple-blind, crossover design with two laboratory sessions 72 hours apart comparing single oral MDMA 1.5 mg/kg to placebo in adults aged 21–40.
Primary aim is basic science: to assess effects of MDMA on responses to affective touch across individuals with varying autistic traits; outcomes include behavioural and neural/emotional process measures.
Participants receive placebo in first session and MDMA (1.5 mg/kg) 72 hours later (crossover).
