Australia became the first country to establish a national regulatory pathway permitting authorised psychiatrists to prescribe 3,4-methylenedioxymethamphetamine (MDMA) for post-traumatic stress disorder (PTSD) and psilocybin for treatment-resistant depression (TRD) through the Therapeutic Goods Administration (TGA) Authorised Prescriber Scheme. Two and a half years after implementation,...

Abstract Chemsex involves the use of psychoactive substances to facilitate or enhance sexual activity, particularly among gay, bisexual, and other men who have sex with men (GBMSM). Common substances used include methamphetamine, gamma‐hydroxybutyric acid/gamma‐butyrolactone (GHB/GBL), mephedrone, ketamine, inhaled nitrites (‘poppers’), and cocaine, all of which are linked to various...

Psychoplastogen compounds such as ketamine and MDMA have shown therapeutic promise for mood and trauma-related disorders, yet the molecular mechanisms underlying their effects remain poorly understood. Here, we applied a Brain-Epigenome-Wide Association Study (BEWAS) targeting brain-relevant genes to examine DNA methylation changes following treatment. Pre- and post-treatment blood (ketamine, N...

This preliminary study explored the effects of MDMA-assisted therapy on trauma symptoms related to discrimination, as measured by the Trauma Symptoms of Discrimination Scale (TSDS). A total of five diverse participants, who experienced multiple types of discrimination (e.g., gender, racial/ethnic, social class, age, sexual orientation), were assessed before and after treatment. A paired-samples...

There is limited or indirect evidence suggesting that combined use of MDMA and SSRIs may increase the risk of serotonin syndrome. Healthcare providers should be vigilant in identifying symptoms and discourage such drug interactions.

Classic serotonergic psychedelics such as psilocybin act as agonists at cortical serotonin (5-HT) 2A receptors (5-HT 2A R), inducing psychedelic effects in humans and head-twitch responses (HTRs) in rodents. Another class of psychedelic drugs called entactogens, exemplified by MDMA, function primarily as monoamine releasers and typically evoke minimal HTR despite causing serotonin release. The...

MDMA therapy is not approved by most medical regulators. But underground use is popular despite a severe lack of adequate practical guidance. Thus, I provide comprehensive practical guidance for solo and guided MDMA therapy based on critical literature synthesis, personal experience, community reports, and a mechanistic framework. I primarily address the individual doing or seeking MDMA therapy...

Objetivo: Avaliar a eficácia e a segurança comparativas da psilocibina e do MDMA (3,4-metilenodioximetanfetamina) no tratamento de pacientes com transtorno de estresse pós-traumático (TEPT) e depressão resistente ao tratamento (DRT), com base na evidência disponível de ensaios clínicos randomizados e estudos controlados. Métodos: Revisão sistemática conduzida segundo as diretrizes PRISMA 2020....

Background Serotonergic psychedelics and MDMA may improve mental health through reductions in neuroticism and changes in personal values. While decreases in neuroticism following serotonergic psychedelics are sometimes observed, it is unclear which facets of neuroticism respond the most, and MDMA remains understudied. People also report value shifts after psychedelic experiences, but...

Background: 3,4-Methylenedioxymethamphetamine (MDMA)-assisted psychotherapy (MDMA-AP) has demonstrated considerable efficacy in treating post-traumatic stress disorder (PTSD). PTSD and complex PTSD (CPTSD) frequently co-occur with borderline personality disorder (BPD), a complex disorder marked by emotional dysregulation, interpersonal difficulties and abandonment fears - often accompanied by...

Based on its in vitro profile and preliminary evidence, 4-bromo-2,5-dimethoxyphenethylamine (2C-B) may have psychoactive properties that are similar to 3,4-methylenedioxymethamphetamine (MDMA) and psilocybin, which are investigated for the treatment of posttraumatic stress disorder and depressive disorders. We compared acute effects of 2C-B (10, 20, and 30 mg), 125 mg MDMA, and 25 mg psilocybin...

Interest in psychedelic drugs has increased rapidly because of their potential therapeutic role in psychiatric disorders. Impairments in the sociocognitive skills needed to build and maintain social relationships are prominent features of many psychiatric and neurodevelopmental disorders. Emerging evidence suggests that compounds such as 3,4-methylenedioxymethamphetamine (MDMA), lysergic acid...

INTRODUCTION: The treatment of comorbid post-traumatic stress disorder (PTSD) and alcohol use disorder (AUD) is significantly more challenging than the treatment of either disorder alone. While gold standard evidence-based treatments exist for this comorbidity, clinically significant improvements are only observed in approximately half of clinical trial participants. The use of adjunctive...
