Beyond Symptom Reduction: Interconnectedness and Self-Transcendent Emotions During MDMA Sessions Predict Flourishing, Not Symptom Change, in Social Anxiety Disorder Treatment

This secondary analysis of a randomized waitlist-controlled trial (N = 20) examined self-transcendent experiences during MDMA-assisted therapy for generalized social anxiety disorder. Connection-oriented experiences predicted greater post-treatment belonging, gratitude and purpose in life, but not reduced social anxiety. The authors describe the findings as groundwork for larger mechanistic trials.

Caution before canonisation: a clinical and implementation science perspective on psychedelics

A review examines psychedelic therapies through clinical, methodological, ethical and implementation science lenses. The authors argue that current trials mainly show proof-of-concept efficacy under controlled conditions rather than readiness for large-scale adoption. They call for stronger evidence on durability, safety monitoring, comparative effectiveness and real-world implementation.

Evaluation of the Effects of Different Doses of Ayahuasca on Intelligence and Verbal Memory in Healthy Volunteers: A Preliminary, Exploratory, Double-Blind, Randomized, Placebo-controlled Study

A double-blind, randomized, placebo-controlled pilot study tested the effect of a single ayahuasca dose on intelligence and verbal memory in 28 healthy volunteers. No persistent changes were found at 21 days; on delayed recall, the 0.5 mL/kg group performed worse than placebo at 4 hours. The authors describe the findings as preliminary and useful for planning larger trials.

Clinical Evidence on Psilocybin and Its Representation in Media Reporting: A Systematic Review

A systematic review compared 70 clinical trials of therapeutic psilocybin (2014 to 2024) with 172 media articles (up to April 2025). Media reports more often presented benefits as established, extended them to indications such as PTSD and anxiety with little trial evidence, and mentioned safety less often than academic publications.

Intravenous Ketamine for Depressed and Suicidal Adolescents in the Emergency Department: A Randomized Double-Blind Trial

In a randomized, double-blind placebo-controlled trial of 29 suicidal adolescents with treatment-resistant depression, one group received a single low dose of intravenous ketamine and the other saline. Ketamine did not produce greater reductions in depression or suicidality scores than placebo, and dissociation signs were more frequent with ketamine. The authors consider the emergency department a feasible setting for rapid antidepressant treatment and call for larger studies.

Dual benefit of esketamine-based opioid-free anesthesia on postoperative pain and mental health outcomes in patients undergoing bariatric surgery: a randomized controlled trial

A double-blind randomized trial of 84 patients undergoing sleeve gastrectomy compared esketamine-based opioid-free anesthesia with opioid-based anesthesia using remifentanil. The esketamine group had significantly lower postoperative pain within 24 hours and better mental health at three months, without more adverse events. The findings suggest possible benefits for pain and mental health, though the setting is anesthesia.

Investigation of the pharmacological and circuit basis for psychedelic drug effects on interval timing in mice.

An animal study in male C57BL/6J mice examined how psilocin, the active metabolite of psilocybin, affects timing performance in the temporal discrimination task. The effect was blocked by the 5-HT2A antagonist M100907 but not by the 5-HT1A antagonist WAY-100,635. Intra-prefrontal infusion of DOI mimicked systemic effects, suggesting the medial prefrontal cortex may mediate psychedelic effects on interval timing.

Low-Dose Buprenorphine Significantly Prolonging the Antisuicidal Effects of Ketamine Infusion in Major Depressive Disorder: Relationship Between Antidepressant and Antisuicidal Effects.

A paper in the American Journal of Psychiatry examines whether low-dose buprenorphine prolongs the antisuicidal effects of ketamine infusion in major depressive disorder. It also looks at the relationship between antidepressant and antisuicidal effects. Further details are only available from the headline.
