Using a MDMA- and LSD-Group Therapy Model in Clinical Practice in Switzerland and Highlighting the Treatment of Trauma-Related Disorders
Using 50 case-by-case licences under Swiss law, the authors developed an MDMA- and LSD-assisted group therapy model for predominantly complex PTSD and other trauma-related disorders, reporting clinical improvement in most participants and no serious adverse events. In their protocol MDMA was used early to strengthen motivation, the therapeutic alliance and emotional regulation, with LSD introduced later to deepen trauma processing, and they note c-PTSD typically requires more psychedelic sessions than single-incident PTSD and that these findings can inform future PAP research.
Abstract
The Swiss Federal Act on Narcotics allows for the restricted medical use of scheduled psychotropic drugs in cases of resistance to standard treatment, and preliminary evidence of efficacy of the scheduled drug for the particular condition. Since 2014, the authors have obtained 50 licenses on a case-by-case basis and developed a psychedelic-assisted group therapy model utilizing MDMA and LSD. The majority of the patients taking part in the psychedelic group therapy suffered from chronic complex post-traumatic stress disorder (c-PTSD), dissociative, and other post-traumatic disorders. Treatment modalities, typical developments and problems encountered during and after the psychedelic experiences are described. Recurrent depression poses a frequent problem, and requires special attention. Symptoms of c-PTSD predominantly addressed by the psychedelic experiences are the regulation of emotions and impulses, negative self-perception, alterations in relationships to others, as well as meaning, recall, and processing of traumatic memories. C-PTSD needs a larger number of psychedelic experiences in contrast to PTSD resulting from single trauma. In this model MDMA was most often used in the first phase to enhance motivation to change, strengthen the therapeutic alliance, allowing it to become more resilient, stress-relieved and less ambivalent. When emotional self-regulation, negative self-perception and structural dissociation had also begun to improve and trauma exposure was better tolerated, LSD was introduced to intensify and deepen the therapeutic process. The majority of participants improved by clinical judgement, and no serious adverse events occurred. A short case vignette describes a typical process. The experiences with this model can serve to further develop the method of psychedelic-assisted psychotherapy (PAP) and to give directions for future research.
Research Summary of 'Using a MDMA- and LSD-Group Therapy Model in Clinical Practice in Switzerland and Highlighting the Treatment of Trauma-Related Disorders'
Introduction
Psychedelics such as LSD, psilocybin and MDMA have a long history of experimental use as adjuncts to psychotherapy, but most early studies lacked modern methodological rigour and research halted after regulatory bans in the 1970s. Clinical research has resumed in recent decades with small Phase II and, more recently, Phase III trials that have generally used individual treatment settings; MDMA in particular has shown promising results for treatment-resistant post-traumatic stress disorder (PTSD). Group-based applications of psychedelics have been reported rarely, with a few historic exceptions in Switzerland and a recent feasibility study of psilocybin in long-term AIDS survivors, but the dominant model in contemporary trials remains individual therapy with one or two therapists per patient. This article describes a clinical, practice-based group model developed in Switzerland from 2014 to 2020 for administering MDMA and LSD as adjuncts to psychotherapy in patients who had not responded to standard treatments. Oehen and colleagues aim to document the practical procedures, dosing rationale, patient selection, typical therapeutic trajectories—particularly for complex PTSD (c-PTSD)—and safety/feasibility observations from 50 licensed, case-by-case treatments. Because these interventions took place under the Swiss “restricted medical use” framework rather than as a prospective research trial, the report is a descriptive clinical account rather than a controlled efficacy study, and standard psychometric measures were not applied routinely.
