Psychometric validation of the French version of the five-dimensional altered states of consciousness questionnaire (5D-ASC) and associated 11 OAV subscales.

Progress in neuro-psychopharmacology & biological psychiatry June 20, 2026 Ewen Kervadec, Pauline Mathieu, Baptiste Fauvel et al.

The renewal of psychedelic medicine has garnered significant scientific interest, with large efforts dedicated to the understanding of the complex subjective experiences induced by these substances. The Altered States of Consciousness (ASC) questionnaire represents the most comprehensive instrument for measuring such experiences yet lacks a validated French translation despite its centrality to...

Protocol for a qualitative mechanistic study of MDMA with a sample of psychoanalytic psychotherapists: A phenomenological investigation

PLoS One June 18, 2026 Elisa Liberati, Hv Curran, Peter Fonagy et al.

INTRODUCTION: Methylenedioxymethamphetamine (MDMA)-assisted psychotherapy (MDMA-AP) is a potentially transformative intervention for post-traumatic stress disorder (PTSD). Despite encouraging Phase III trial results, the psychological mechanisms underpinning MDMA's therapeutic effects remain insufficiently understood. Existing research on MDMA has emphasised neurobiological processes but has...

MDMA-induced CYP2D6 inhibition: concentration-dependent variability using dextromethorphan as a probe

Drug Metabolism and Personalized Therapy June 16, 2026 Faezeh Ahmadi, Hoda Lavasani, Mohammadhosein Keshvadi et al.

OBJECTIVES: Ecstasy is commonly abused due to entactogenic effects. Although our previous studies on isolated perfused rat model confirmed inhibition of CYP2D6 by MDMA, the time for enzyme recovery was different when mirtazapine and tramadol were used as substrates. Therefore, present study intended to investigate CYP2D6 inhibition by MDMA using dextromethorphan as a well-known probe. Two...

Shifting Patterns in Ecstasy Use: Increasing Detection of MDA in Forensic Seizures and Toxicological Cases in Southern Brazil

Journal of Psychoactive Drugs June 10, 2026 Bruno Pereira Dos Santos, Vítor Camargo Pôrto, Letícia Birk et al.

Ecstasy-type drugs are the most frequently seized synthetic drugs in Brazil, usually containing a mixture of MDMA and its analog MDA. In recent years, an increasing number of samples have been found to contain only MDA, possibly reflecting shifts in the synthetic routes of ecstasy-type substances during the COVID-19 pandemic. However, the exclusive use of MDA remains poorly characterized, and...

Semi-Quantitative Estimation of MDMA Tablet Dosage and Cocaine/Ketamine Purity Using a Simple to Operate Field-Portable Device

ChemRxiv June 9, 2026 Matthew Gardner, Alexander Power, Anca Frinculescu et al.

High-dose MDMA tablets and variable-purity cocaine and ketamine samples are commonly encountered by drug checking services and police forces in the United Kingdom and Europe. At the time of writing, there are few simpleto-operate field-portable technologies that provide semi-quantitative information on MDMA tablet dosage or cocaine and ketamine purity at the point of sampling. We previously...

Psychedelic-Assisted Psychotherapy for the Treatment of PTSD: A Systematic Review and Meta-Analysis

Psychoactives June 8, 2026 Fizza Mitter, Anton Sheptooha, Janni Leung et al.

Post-traumatic stress disorder (PTSD) remains inadequately treated by existing pharmacological and psychological interventions, prompting growing interest in psychedelic-assisted psychotherapy. Although randomised controlled trials have evaluated several psychedelic agents for PTSD, to our knowledge, no prior PTSD-specific synthesis has quantitatively examined multiple agent classes within a...

Understanding How Trait Negative Emotionality (NEM) Influences Social Connectedness and Responses to ± 3,4-Methylenedioxymethamphetamine (MDMA)

University of Chicago June 6, 2026 Ruiyan Hu

Negative Emotionality (NEM) is a trait measure that reflects a tendency toward experiencing intense negative emotions and heightened reactivity to perceived threats or stressors, contributing to challenges with social integration and interpersonal relationships. This secondary analysis in healthy volunteers (N = 30) employed a within-subject, double-blind, placebo-controlled design to...

The Role of the Basolateral and Central Amygdala During Heroin Withdrawal and 3,4-Methylenedioxymethamphetamine Administration

UNC Libraries June 5, 2026 Charlotte Rubin

Opioid use disorder (OUD) is characterized by dependence, withdrawal, and high relapse risk, yet the neuroimmune mechanisms underlying withdrawal in the amygdala remain poorly understood. This study investigated whether 3,4-methylenedioxymethamphetamine (MDMA) modulates heroin withdrawal–induced neuroinflammation in the central amygdala (CeA) and basolateral amygdala (BLA). Adult male...

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. Aims: Develop a preliminary estimate of clinical response and safety for MDMA-AT versus waitlist in adults with SAD. Secondary aims included refinement of a standardized psychotherapy...

Comparison of acute effects of 3,4-methylenedioxymethamphetamine (MDMA) with and without a supplemental booster dose in healthy participants: a double-blind, randomized, placebo-controlled, crossover study

Translational Psychiatry June 4, 2026 Mélusine Humbert‐droz, Anna M Becker, Jan Valenta et al.

3,4-Methylenedioxymethamphetamine (MDMA)-assisted psychotherapy (MDMA-AT) is being investigated as a treatment for several psychiatric disorders, particularly posttraumatic stress disorder. Phase 2 and 3 trials typically administered a first dose of MDMA followed by a second "booster" dose 1.5-2.5 h later, to extend the acute effect duration. However, the risks and benefits of the booster dose...

Exploring Attitudes Toward MDMA-Assisted Therapy in Mental Health Care

European Psychiatry June 1, 2026 Agnieszka Mechlińska, Damian Swieczkowski, Aleksander Kwaśny et al.

Introduction MDMA (3,4-methylenedioxymethamphetamine)–assisted therapy has gained growing scientific attention as a potential treatment for post-traumatic stress disorder and other mental health conditions.

Synthetic Drugs and Behavioural Addictions: LSD, MDMA and Digital Toxicity

June 1, 2026 Sharda More-Pol

The emergence of contemporary psychological stressors, synthetic psychoactive substance abuse, and non-substance behavioral dependency networks presents critical investigative challenges within public healthcare and classical toxicology (Agadatantra), traditionally analyzed through the concepts of Madya (intoxicants), Mada (intoxication), and severe cognitive perversion (Prajñāparādha). This...

Monday mood decline after weekend ecstasy use: A retrospective analysis of daily diary reports.

Drug and Alcohol Dependence Reports June 1, 2026 Christopher Medina-Kirchner, Scott E Lukas

Ecstasy is commonly used on weekends and linked to post-use mood declines. Laboratory studies with pure MDMA rarely detect residual effects, whereas naturalistic studies more often report mood reductions. The timing and contextual drivers of these effects remain unclear. Data from seventeen participants reporting weekend ecstasy use (10 male, 7 female; 19-38 years) were drawn from a previously...

(2026)'s recent State of the Science article on 3,4-methylenedioxymethamphetamine (MDMA)-assisted psychotherapy for posttraumatic stress disorder (PTSD), we aim to emphasize both MDMA's therapeutic promise and its unresolved scientific challenges. Although recent trials on MDMA-assisted interventions have reported encouraging reductions in PTSD symptoms, the...
