The study investigators are conducting the first open label pilot trial of MDMA-assisted
therapy (MDMA-AT) with a comorbid sample of military veterans with a comorbid diagnosis of
Alcohol Use Disorder (AUD) and Post-Traumatic Stress Disorder (PTSD). This novel experimental
treatment package consists of two once-monthly Experimental Sessions of therapy combined with
a divided-dose of MDMA HCl, along with non-drug preparatory and integrative therapy. The
Primary Outcome measure, the Timeline Follow-back (TLFB), will evaluate changes in alcohol
use over time. Changes in PTSD symptoms will also be evaluated.
