Prior to the first session with MDMA and CBCT, participants will undergo an introductory psychotherapy session via telemedicine (videoconference) followed by a five-hour CBCT visit at the study site. After each MDMA+CBCT session, the pair will have integrative sessions that include an on-site integrative session on the day following MDMA+CBCT and further integrative and CBCT sessions conducted via videoconference.
