PSI has developed a knowledge base of information related to psychedelic psychedelic safety, harm reduction, and public health. A field can only align if it has shared knowledge and language. PSI synthesizes insights from peer-reviewed research, clinical trials, case reports, government datasets, harm reduction field reports, and practitioner guidance — making the best available evidence accessible and actionable across the psychedelic ecosystem.

PSI has conducted systematic field research across legal, therapeutic, underground, and campus contexts to understand real-world needs, challenges, and safety priorities in the psychedelic space. This collection represents a comprehensive effort to map the psychedelic landscape through direct engagement with stakeholders across legal, therapeutic, underground, and campus contexts.
These resources document what we learned by going directly to the field — not just published literature, but lived experience from those working at the frontlines of psychedelic access, harm reduction, and policy reform. We share these resources publicly to benefit the entire field and support evidence-based advocacy, harm reduction programming, policy development, and further research.

Evidence-Based Guidance
for Safer Psychedelic Experiences
Psychedelic use is happening across diverse contexts — from clinical trials and regulated frameworks to underground ceremonies and personal exploration. To support safety across this spectrum, we've developed comprehensive educational guides that synthesize research, case reports, and field expertise into practical, evidence-based resources.
Each guide is designed for a specific audience but shares a common foundation: preparing thoughtfully, recognizing risks early, responding compassionately, and supporting meaningful integration.
