Bridging veteran psychedelic peer expertise with research and clinical care: Peer Readiness and Education for Psychedelic Practice (PREPP) workshop

Psychedelics August 13, 2026 Stephanie R. Rodriguez, PSS Daniel Friedrich, Kim Hoffman et al.

Psychedelics have been researched for decades, yet clinical investigations represent only a small fraction of their use.

Journal of Psychoactive Drugs August 5, 2026 Catherine S. Hwang, David C. Cameron, Allison O’Neill et al.

3,4-methylenedioxymethamphetamine (MDMA)-assisted therapy has emerged as a potential strategy to treat posttraumatic stress disorder (PTSD). We conducted a national serial cross-sectional study of U.S. Veterans with PTSD from January 1, 2018, to December 31, 2023, to quantify the prevalence of potential contraindications, risk factors, and drug-drug interactions relevant to MDMA-assisted...

OPTICS: Opinions and Preferences for Treatments In Community Samples

Open MIND July 14, 2026 Christina Chwyl, Jason B. Luoma, Stephanie R. Rodriguez et al.

PTSD is a prevalent and debilitating condition, for which many individuals do not seek or complete treatment. As new PTSD treatments are being evaluated, such as psychedelic-assisted therapies, it’s important to understand the preferences of individuals for whom these treatments are being developed. To date, no research has directly compared preferences for psychedelic-assisted therapies...

MDMA-Assisted Therapy for Social Anxiety Disorder: A Randomized, Open-label, Wait-list Controlled Trial

June 4, 2026 Jason B. Luoma, M. Kati Lear, Brian Pilecki et al. preprint

Background: ±3,4-methylenedioxymethamphetamine (MDMA) has positive effects on socio-emotional processing and MDMA-Assisted Therapy (MDMA-AT) showed promise for treating SAD in a previous placebo-controlled trial.

Inflammatory biomarker outcomes associated with MDMA-assisted therapy: an open-label exploratory study.

Frontiers in Neuroscience 2026 Jenna E Kachmarik, Jennifer M Loftis, Christopher S. Stauffer

Posttraumatic stress disorder (PTSD) is associated with elevated inflammation and risk for chronic illness, yet few studies have examined inflammatory biomarker outcomes of PTSD interventions. Rapid PTSD symptom reduction has been observed following 3,4-methylenedioxymethamphetamine (MDMA)-assisted therapy, which leverages MDMA as a prosocial adjunct to psychotherapy. No studies have evaluated...

Exploring psychedelic experiences among people who regularly use methamphetamine: Findings from an international survey.

Drug and Alcohol Dependence July 1, 2025 Dilara Bahceci, Krista J. Siefried, Maureen Steele et al.

Methamphetamine use disorder, associated with significant morbidity and mortality, has limited effective treatments. Psychedelic-assisted psychotherapy shows promise, but data on its safety and efficacy in this population are limited. This exploratory study describes the demographic, substance use, and mental health characteristics of people who used methamphetamine and psychedelics and the...

Bringing MDMA-assisted therapy for PTSD to traditional healthcare systems: tending to set and setting.

Frontiers in Psychiatry 2025 Dimitri Perivoliotis, Kayla Knopp, Shannon Remick et al. 2 citations

Although effective evidence-based trauma-focused psychotherapies for posttraumatic stress disorder (PTSD) are available, a significant proportion of patients show a suboptimal response or do not complete them. MDMA-assisted therapy (MDMA-AT) for PTSD is a promising intervention currently being evaluated in numerous studies worldwide, including investigation for potential Food and Drug...

Developing the Open Psychedelic Evaluation Nexus consensus measures for assessment of supervised psilocybin services: An e-Delphi study

Journal of Psychopharmacology June 18, 2024 Kim Hoffman, Alissa Bazinet, Kellie Pertl et al. 14 citations

Background: Voter initiatives in Oregon and Colorado authorize legal frameworks for supervised psilocybin services, but no measures monitor safety or outcomes. Aims: To develop core measures of best practices. Methods: A three-phase e-Delphi process recruited 36 experts with 5 or more years’ experience facilitating psilocybin experiences in various contexts (e.g., ceremonial settings,...

Getting in Touch with Touch: The Importance of Studying Touch in MDMA-Assisted Therapy and the Development of a New Self-Report Measure.

Psychedelic medicine (New Rochelle, N.Y.) March 1, 2024 Jason B. Luoma, Luke R Allen, Veronika Gold et al. 14 citations

MDMA-assisted therapy (MDMA-AT) is an emerging treatment modality, with recent phase 3 trials indicating its potential for regulatory approval. Central to this therapy is the role of touch, yet its empirical evaluation in MDMA-AT, and psychotherapy in general, remains limited. The use of touch in combination with MDMA raises concerns about power imbalances and ethical boundaries. This article...

Frontiers in Psychiatry December 6, 2023 Elliot Marseille, Manish Agrawal, Paul Thambi et al. 40 citations

Objective To compare group and individual psychedelic-assisted therapy in terms of clinician time, costs and patient access. Methods Using 2023 data from two group therapy trial sites, one using 3,4-Methylenedioxymethamphetamine (MDMA) to treat posttraumatic stress disorder (PTSD), and one using psilocybin to treat major depressive disorder (MDD), we compared overall variable costs, clinician...

Peer support and psychedelics.

Journal of military, veteran and family health December 1, 2023 Zachary Skiles, James R Dixon, Dan Friedrich et al.

The field of psychedelic-assisted psychotherapy and state-run psychedelic services will need to adequately train and certify facilitators to meet the anticipated demand for access.

Frontiers in Psychiatry March 14, 2023 Jonathan Brett, Elizabeth Knock, Paul Liknaitzky et al. 16 citations

Methamphetamine use disorder is a chronic relapsing condition associated with substantial mental, physical, and social harms and increasing rates of mortality.

ACS Pharmacology & Translational Science December 9, 2020 Christopher S. Stauffer, B. Anderson, Kile Ortigo et al. 65 citations

Attachment insecurity is determined early in life, is a risk factor for psychopathology, and can be measured on two separate continuous dimensions: attachment anxiety and attachment avoidance. Therapeutic changes toward more secure attachment correlate with reduction in psychiatric symptoms. Psilocybin-assisted psychotherapy has demonstrated promise in the treatment of psychopathology, such as...

Journal of Psychoactive Drugs March 15, 2019 Alexander Trope, B. Anderson, Andrew R. Hooker et al. 113 citations

Contemporary research with classic psychedelic drugs (e.g., lysergic acid diethylamide (LSD) and psilocybin) is indebted to the twentieth-century researchers and clinicians who generated valuable clinical knowledge of these substances through experimentation. Several recent reviews that highlight the contributions of this early literature have focused on psychedelic-assisted individual...
