Anxiety Disorders

Anxiety disorders, affecting around 300 million people globally, are among the most prevalent mental health conditions. Emerging clinical research suggests that various psychedelics, including psilocybin, MDMA, and LSD, hold potential for alleviating anxiety symptoms through innovative therapeutic approaches.

Efficacy and Safety of the Neuroplastogen TSND-201 for the Treatment of PTSD A Randomized Clinical Trial

In a multicentre, double‑blind, placebo‑controlled phase 2 trial of 65 adults with chronic PTSD, once‑weekly oral TSND‑201 produced significantly greater reductions in clinician‑rated PTSD severity (CAPS‑5; LS mean difference 9.64, P = .01) and improvements in self‑reported symptoms, functioning and depression versus placebo. TSND‑201 was generally well tolerated — common adverse events included headache, decreased appetite, nausea, dizziness and transient blood‑pressure increases — supporting its potential as a rapid‑acting, durable treatment for PTSD.

Naturalistic psychedelic use and changes in depressive symptoms

This longitudinal observational study (n=12,345) of U.S. residents found that naturalistic psychedelic use (n=505, 4.1% of participants) was associated with modest increases in depressive symptoms, particularly when occurring in 'risk contexts' characterised by negative mindset and lack of psychological support, with challenging psychedelic experiences mediating this relationship and suggesting that unsupervised psychedelic use may not be generally therapeutic and could worsen depression under certain circumstances.

DMT and harmala alkaloids: an exploratory study of oral Acacia based formulations in healthy volunteers

In this open-label exploratory crossover study of nine experienced ayahuasca users, three Acacia‑derived oral formulations delivering DMT plus harmala alkaloids were well tolerated, produced no clinically significant physiological changes, and elicited psychedelic effects rated comparable to (and for ACL‑010 sometimes more beneficial than) traditional ayahuasca. These findings suggest Acacia‑based DMT/harmala formulations are a feasible alternative for future clinical trials, although generalisability is limited by the small sample size and open‑label design.

Safety, tolerability and subjective effects of vaporized N,N-Dimethyltryptamine: A randomized double-blind clinical trial

This first RCT (n=25) of vaporised DMT (60mg) demonstrated that DMT significantly increased subjective experience measures while causing only transient, safe physiological changes and predominantly mild adverse events. This suggests that inhaled DMT is safe, well-tolerated, and effective at inducing profound altered states of consciousness. Significant correlations were observed between physiological responses and subjective experiences.

Rapid and sustained antidepressant effects of vaporized N,N-dimethyltryptamine: a phase 2a clinical trial in treatment-resistant depression

This open-label fixed-order dose-escalation trial (n=14) evaluated inhaled DMT (15mg & 60mg) for treatment-resistant depression (TRD) for the first time. Results showed rapid and sustained antidepressant effects with a 21-point reduction on the Montgomery-Asberg Depression Rating Scale by day 7 (p<0.001), an 86% response rate, and a 57% remission rate lasting up to 3 months, with significant decreases in suicidal ideation (SI).

Insights on Psychedelics: A Systematic Review of Therapeutic Effects

This systematic review (s=98) examining psychedelic-catalysed insight found that 86% of studies showed insight was linked to therapeutic improvement, with insight being dose-dependent and significantly higher than placebo in 93% of comparative studies, suggesting insight may be a key mechanism in psychedelic therapy.
