“I even saw four deer grazing”: online-offline entanglements in the psilocybin pluriverse

June 17, 2026 Michał Wanke, Paweł Matuszewski, Piotr Siuda

An analysis of approximately 3,000 posts from a Polish online drug forum (mid-2000s–2023) shows that after 2020, discussions about psilocybin mushrooms shifted from immersive, metaphysical narratives toward predictive, scientifically informed, and risk-managed practices. Forum users increasingly integrated digital tools like mapping and smartphone verification with environmental field observations, reflecting online-offline entanglements and more-than-human relations of foraging. The forum functions as an apparatus within a psychedelic pluriverse, where different versions of psilocybin coexist, negotiate legitimacy, and sustain themselves. The study demonstrates how digital platforms and embodied ecological practices jointly shape contemporary psychedelic practices, highlighting their relational, contingent, and ethically informed character.

The quality and scope of health information on online drug platforms: a topic modelling and expert evaluation study of a Polish-language forum

Harm Reduction Journal March 29, 2026 Piotr Siuda, Paweł Matuszewski

An analysis of the largest Polish drug forum, Hyperreal, found that health-related posts about psychoactive substances had moderate quality. Topic modeling of 159,145 posts revealed associations between specific drugs and health topics—such as ketamine with depression, marijuana with symptom relief, amphetamines with cardiovascular issues, and fentanyl with palliative care—that mirrored medical literature, indicating knowledge grounded in evidence rather than anecdote. However, expert evaluation using a custom questionnaire showed significant informational gaps. The mean quality score was 35.67 out of a possible range, with factual accuracy rated moderate and safety aspects—especially dosage guidance and encouragement to consult specialists—scoring lowest. The findings highlight the need to improve content quality on drug forums for harm reduction.
