2020 | Forbes, D., Gibson, K., Varker, T., Watson, L.

This review (9 studies) investigated the therapeutic potential of MDMA, ketamine, LSD, and psilocybin as a therapeutic agent for PTSD.

The Potential Dangers of Using MDMA for Psychotherapy

2014| Parrott, A. C.

This review (2014) examines both the negative and positive aspects of using MDMA for psychotherapy, with specific regard to its neurohormonal profile, the effects of serotonergic depletion, and neurotoxicity of repeated usage. The most critical issues are related to the release of difficult feelings and memories and the lack of control thereof due to heightened environmental sensitivity, as well as the risk that negative mood states predominating the phase of neurochemical recovery amongst certain individuals.

2019| Barone, W., Beck, J., Mitsunaga-Whitten, M., Perl, P.

This long-term follow-up study (n=24) applied qualitative interviews, an interpretative phenomenological analysis, and quantitative questionnaires to assess the perceived benefits of MDMA-assisted psychotherapy, following a two-year period after the completion of a Phase II clinical trial. Participant depictions of their experience before, during, and in the year after the treatment provide a rich context that demonstrates how MDMA-assisted psychotherapy can impact important areas of functioning as well as the overall quality of life, regardless of changes to PTSD symptoms.

One month after two sessions, the higher doses of MDMA showed the largest reduction on a PTSD Scale. At the 12-month follow-up, PTSD symptoms remained lower than baseline with 75% of the participants not meeting PTSD criteria.
