Content analysis of Reddit posts about coadministration of selective serotonin reuptake inhibitors and psilocybin mushrooms.

RATIONALE: Treatments with the serotonergic psychedelic psilocybin are being investigated for multiple neuropsychiatric disorders. Because many patients with these disorders use selective serotonin reuptake inhibitors (SSRIs), understanding interactions between psilocybin and SSRIs is critical for evaluating the safety, efficacy, and scalability of psilocybin-based treatments. Current knowledge about these interactions is limited, as most clinical psilocybin research has prohibited concomittant SSRI use. OBJECTIVES: We aimed to explore potential interactions between psilocybin and SSRIs by characterizing peoples' real-world experiences using psilocybin mushrooms and SSRIs together. METHODS: We conducted a systematic search of Reddit for posts describing psilocybin mushroom and SSRI coadministration. We identified 443 eligible posts and applied qualitative content analysis to each. RESULTS: 8% of posts reported negative physical or psychological effects resulting from coadministration. These included 13 reports that may reflect serotonin toxicity, and 1 concerning for a psychotic/manic episode. 54% of posts described reduced intensity of the acute psilocybin experience, but 39% reported unchanged intensity with SSRI coadministration. CONCLUSIONS: Psilocybin's interactions with SSRIs are likely complex and may depend on multiple factors. Prospective studies are needed to evaluate whether psilocybin treatments are reliably safe and effective in the setting of SSRI use.

Reducing the Harms of Nonclinical Psychedelics Use Through a Peer-Support Telephone Helpline.

Introduction: A resurgence of interest in the use of psychedelics for mental health and wellness has stimulated greater experimentation with psychedelics in society. Although clinical psychedelic trials protect research participants by offering a safe setting, thorough preparation, and containment during and after ingestion of psychedelic medicines, many try these substances without the benefit of these safeguards. Materials and Methods: We analyzed data gathered from 884 callers to a psychedelic helpline to determine whether a helpline model could reduce the risks associated with nonclinical psychedelics use. Results: In total, 65.9% of callers indicated that the helpline de-escalated them from psychological distress. If not for their conversation with the helpline, 29.3% of callers indicated they may have been harmed; 12.5% indicated that they may have called 911; and 10.8% indicated they may have gone to the emergency room. Conclusion: The data suggest that access to a psychedelic helpline surrounding psychedelic experiences may avert harmful outcomes and offset the burden on emergency and medical services.
