MDMA-Assisted Therapy

MAPS / Mithoefer · 2021
Key text: MAPS publications
Psychedelic Focus: Experiential + Processing Short (3 sessions) Individual (co-therapist)

Core Mechanism

MDMA reduces fear response and increases trust/empathy, enabling deeper trauma processing within 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


Evidence

FDA declined approval (2024) citing methodology; not currently approved

Phase 3 trials (Mitchell et al., 2021, 2023)

Phase 3 data analyzed

Phase 3 showed large effects. FDA advisory committee voted against approval Aug 2024 — functional unblinding and data concerns. Regulatory status unresolved.

Controversies & Ethical Concerns

FDA declined approval Aug 2024 (methodological concerns, unblinding, data integrity). Regulatory future uncertain

2024 legal

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.

2022 org

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.
