Thirty psychedelic researchers identified critical gaps in knowledge about harms from psychedelic use, including how to define those harms, predict them, and treat them effectively. They recommend better online information, peer support groups, affordable therapy, and psychiatric consultation for people experiencing post-psychedelic difficulties. The researchers also call for improved funding for a psychedelic safety net, suggesting that psychedelic philanthropists, investors, and companies commit 1% of their investment to support safety measures such as research and support services. The article outlines practical steps to make the field of psychedelic medicine safer.

Socioeconomic status (SES) strongly affects mental health outcomes and treatment access, but its reporting in psychedelic-assisted therapy trials is inadequate. A systematic review of 98 articles (49 primary trials and 49 secondary analyses) from 2006 to 2024 found that only 12% of primary trials reported participant income data, and 31% reported educational attainment. In US-based trials, participants had markedly higher SES than the general population: 93% had some college education (versus 62% nationally), and median incomes in major trials substantially exceeded the national median for all workers. Non-US trials showed variable patterns. This underreporting and evidence of socioeconomic disparities highlights an urgent need for standardized SES reporting and strategies to improve socioeconomic diversity in psychedelic-assisted therapy research.

HIV-related shame predicts substance use and poor antiretroviral adherence among people with HIV, hindering national epidemic-ending goals. In a pilot clinical trial with 12 participants, psilocybin-assisted group therapy produced a large decrease in HIV-related shame, with a median reduction of 5.5 points on the HIV and Abuse Related Shame Inventory from baseline to 3-month follow-up. However, two participants experienced a paradoxical worsening of sexual abuse-related shame after psilocybin, raising concerns about its use in patients with trauma. These preliminary results suggest potential for addressing HIV-related shame but highlight cautions.

A novel approach combines psychedelic therapy with 12-step programs to improve engagement in community-based recovery from substance use disorders. The authors argue that psychedelics may enhance openness, spiritual experiences, and social bonding, which could increase participation in 12-step meetings and practices. This accessible strategy aims to leverage existing recovery communities, potentially broadening treatment options without requiring extensive clinical infrastructure. The paper presents a theoretical framework for integrating these modalities, suggesting that such augmentation could improve outcomes for individuals with substance use disorders, though empirical evidence is not provided.

Methamphetamine use disorder (MeUD) has no FDA-approved pharmacotherapies and is linked to poor neurological, psychiatric, and cardiovascular outcomes, especially among low-income populations, while also increasing risks for sexually transmitted infections. The Ketamine-Assisted Recovery (KARE) trial is an open-label pilot study enrolling 12 to 24 Medicaid- or Medicare-insured adults with moderate-to-severe MeUD and HIV risk factors. Participants will receive three intramuscular ketamine sessions (0.50-0.75 mg/kg) combined with seven motivational enhancement therapy sessions over five weeks. The study will assess feasibility, acceptability, tolerability, safety, and potential mechanisms such as psychological flexibility, laying groundwork for future randomized trials.
