MDMA-Assisted Therapy
Core Mechanism
MDMA reduces the fear response and increases trust and empathy, making it possible to stay with trauma material inside the therapeutic relationship
Ontology
PTSD maintained by overwhelming fear that prevents therapeutic engagement; MDMA lowers this barrier pharmacologically
Therapeutic Voice
"You're safe here. If something difficult comes up, you can move toward it. You don't have to do this alone."
View of the Person
A traumatized being whose fear barriers to therapeutic engagement can be pharmacologically lowered to enable processing

Controversies & Ethical Concerns
FDA declined approval Aug 2024 (methodological concerns, unblinding, data integrity). Regulatory future uncertain. Separately, a former trial participant alleged inappropriate touch by two trial therapists during MDMA sessions; one of the therapists subsequently surrendered his license
The FDA declined to approve MDMA-assisted therapy for PTSD, citing trial design concerns, potential for bias, and safety risks. An advisory committee voted 9-2 against approval. Concerns included misconduct allegations during trials and blinding integrity questions.
MAPS expressed disappointment and stated it would work with FDA on a path forward. Supporters argue the FDA applied unusually stringent standards compared to other psychiatric medications.
Former trial participant Meaghan Buisson alleged inappropriate touch by therapists Richard Yensen and Donna Dryer during MDMA sessions. Allegations featured in the podcast Cover Story: Power Trip. Yensen’s license was subsequently surrendered.
MAPS acknowledged the allegations and published a Code of Ethics. Critics noted the Code’s promise to ‘never abandon a participant’ contradicted reported experiences of complainants.
