MDMA-assisted psychotherapy reduces posttraumatic stress disorder symptoms more than a low dose, with effects lasting at least 12 months. In a double-blind trial, 28 people with chronic PTSD received either 100 mg, 125 mg, or 40 mg of MDMA during psychotherapy sessions. The active dose groups showed larger reductions in Clinician-Administered PTSD Scale scores one month after two sessions, with mean changes of -26.3 for 125 mg, -24.4 for 100 mg, and -11.5 for 40 mg. At 12-month follow-up, 76% no longer met PTSD criteria. No serious adverse events occurred, and the treatment was well-tolerated.
