This review describes the history, pharmacology, safety, and clinical uses of MDMA. Most clinical research has focused on MDMA-assisted psychotherapy for PTSD, which is now in Phase 3 trials with a target for FDA and EMA licensing in 2021. The paper also covers other potential applications, including treating anxiety in autism and the authors' ongoing study on MDMA-assisted psychotherapy for alcohol use disorder. If efficacy criteria are met, MDMA would become a licensed medicine.

In a first study of its kind, 3,4-methylenedioxymethamphetamine (MDMA)-assisted psychotherapy was found to be safe and tolerable for patients with alcohol use disorder. The treatment did not raise serious safety concerns and was well tolerated by participants, suggesting that this combined approach warrants further investigation as a potential therapy for alcohol addiction.

An open-label study of 14 participants found that mood remained positive during the week after receiving MDMA in a clinical setting, contrary to the 'Blue Monday' crash reported by recreational users. Self-reported sleep quality improved at 3- and 6-month follow-ups compared to baseline. No participants used or desired to use illicit MDMA, and anecdotal reports were favorable. The findings suggest that negative after-effects previously associated with MDMA may stem from confounds such as illicit drug sourcing and recreational settings, rather than the drug itself.

In an open-label feasibility study, 14 adults with alcohol use disorder who had recently completed detoxification underwent an eight-week course of ten psychotherapy sessions, including two sessions with MDMA. Bayesian analysis estimated a 55%–63% probability of a two-level reduction in World Health Organization drinking risk three months after treatment. Preliminary findings also indicated reductions in alcohol craving and improvements in sleep and aspects of psychosocial functioning at the three-month follow-up compared to baseline. The results provide initial insights into MDMA-assisted psychotherapy's potential to improve quality of life and well-being beyond reducing drinking.
Psychedelics as Psychiatric Medications
March 1, 2023
Laurie Higbed, Ben Sessa
Psychedelic compounds present a distinct approach to mental health treatment, explored here as an alternative to standard maintenance medication. Used in controlled clinical settings as an adjunct to psychotherapy, the psychedelic experience allows individuals to access and examine the root causes of their difficulties. This approach emphasizes an individualized, formulation-driven understanding of mental distress rather than a reductionist diagnostic one, offering a holistic biopsychosocial intervention. The chapter details key therapeutic phases—preparation, psychedelic drug-assisted experiential sessions, and post-drug integration—to explain how psychedelics can benefit therapy for various mental health problems.
