Can MDMA Play a Role in the Treatment of Substance Abuse?

Abstract

A wider array of treatments are needed for people with substance abuse disorders. Some psychedelic compounds have been assessed as potential substance abuse treatments with promising results. MDMA may also help treat substance abuse based on shared features with psychedelic compounds and recent reports indicating that MDMA-assisted psychotherapy can reduce symptoms of PTSD. Narrative reports and data from early investigations found that some people reduced or eliminated their substance use after receiving MDMA, especially in a therapeutic setting. MDMA is a potent monoamine releaser with sympathomimetic effects that may indirectly activate 5-HT2A receptors. It increases interpersonal closeness and prosocial feelings, potentially through oxytocin release. Findings suggest that ecstasy, material represented as containing MDMA, is associated with deleterious long-term effects after heavy lifetime use, including fewer serotonin transporter sites and impaired verbal memory. Animal and human studies demonstrate moderate abuse liability for MDMA, and this effect may be of most concern to those treating substance abuse disorders. However, subjects who received MDMA-assisted psychotherapy in two recent clinical studies were not motivated to seek out ecstasy, and tested negative in random drug tests during follow-up in one study. MDMA could either directly treat neuropharmacological abnormalities associated with addiction, or it could indirectly assist with the therapeutic process or reduce symptoms of comorbid psychiatric conditions, providing a greater opportunity to address problematic substance use. Studies directly testing MDMA-assisted psychotherapy in people with active substance abuse disorder may be warranted.

Durability of improvement in posttraumatic stress disorder symptoms and absence of harmful effects or drug dependency after 3,4-methylenedioxymethamphetamine-assisted psychotherapy: a prospective long-term follow-up study

Abstract

We report follow-up data evaluating the long-term outcomes for the first completed trial of 3,4-methylenedioxymethamphetamine (MDMA)-assisted psychotherapy for chronic, treatment-resistant post-traumatic stress disorder (PTSD) (Mithoefer et al., 2011). All of the 19 subjects who received MDMA-assisted treatment in the original trial participated in the long-term follow-up (LTFU), with 16 out of 19 completing all of the long-term outcome measures, which were administered from 17 to 74 months after the original study’s final MDMA session (mean = 45.4; SD = 17.3). Our primary outcome measure used was the Clinician-Administered PTSD Scale (CAPS). Secondary outcome measures were the Impact of Events Scale-Revised (IES-R) and the Neuroticism Extroversion Oppenness Personality Inventory-Revised (NEO PI-R) Personality Inventory. We also collected a long-term follow-up questionnaire. Results for the 16 CAPS completers showed there were no statistical differences between mean CAPS score at LTFU (mean = 23.7; SD = 22.8) (t_matched = 0.1; df = 15, p = 0.91) and the mean CAPS score previously obtained at Study Exit (mean = 24.6, SD = 18.6). On average, subjects maintained statistically and clinically-significant gains in symptom relief, although two of these subjects did relapse. It was promising that we found the majority of these subjects with previously severe PTSD who were unresponsive to existing treatments had symptomatic relief provided by MDMA-assisted psychotherapy that persisted over time, with no subjects reporting harm from participation in the study.
