Mystical experience—characterized by oceanic boundlessness, ego dissolution, and universal interconnectedness—may be a psychological mechanism influencing outcomes in psychedelic therapy. A review of 12 studies using psilocybin, ayahuasca, or ketamine found that 10 reported a significant association (correlation, mediation, or prediction) between mystical experience and symptom reduction across cancer-related distress, substance use disorder, and depressive disorders including treatment-resistant depression. However, most studies had small, non-diverse samples, and half were open-label, introducing potential bias. Future research needs larger, more diverse randomized designs and deeper exploration of mystical experience's nature and predictors to maximize therapeutic benefits while minimizing anxiety.

A network meta-analysis of 27 randomized trials found that NMDA-targeting medications (e.g., ketamine) are markedly more effective than placebo for augmenting treatment-resistant depression (effect size 0.91). Antipsychotics, mood stabilizers, and other pharmacological augmenters were also compared, but NMDA therapies had the highest probability of being effective. No psychological augmentation trials could be included due to the lack of a common comparator. The evidence is limited by few trials, heterogeneity, and inconsistent safety reporting.

People who use psychedelics and attend integration groups report that these groups provide essential community support and help process psychedelic experiences, but also face challenges such as managing group dynamics and ensuring facilitators are adequately trained. Three main themes emerged: reasons for attending, utility of the groups, and adverse factors affecting experience. While integration groups can reduce some risks of unregulated psychedelic use, research is needed to develop standardized protocols and facilitator training to improve their safety and effectiveness.

PTSD is a common and debilitating condition that current treatments only partially address. This review examines psilocybin, a classical psychedelic, as a potential therapeutic agent. It synthesizes recent literature on psychedelic therapies for trauma-related conditions, including treatment-resistant depression and end-of-life anxiety. The authors propose a conceptual framework viewing PTSD as a maladaptive interpretive framework that psilocybin may disrupt through its psychopharmacological properties and subjective effects. A clinical narrative illustrates this process. Recommendations emphasize rigorous, trauma-informed protocols for safe administration in medical research settings.

Among 873 people who reported trauma symptoms or a PTSD/CPTSD diagnosis, 94.8% had experienced psychological trauma and 73.4% had a formal diagnosis. Many had tried multiple medications and psychotherapies but were highly dissatisfied. Significant numbers used marijuana, psychedelics, or MDMA on their own to manage symptoms, with few physical or psychological complications. After learning about MDMA and psilocybin therapies, willingness to try them was high (0.81 and 0.83, respectively). Women and heterosexual individuals showed lower willingness, while younger and more educated respondents were more willing. The findings point to a need for further clinical research and public education about risks and harm reduction.
