The Psychedelic Library is published and created by advocates for legal psychedelic medicine. We believe people deserve clear, honest information about what the research does and doesn't show.
Editorial policy
- Evidence over hype. We report what studies found, including null results, limitations and risks.
- Every claim is sourced. Each study summary links to the original paper.
- Evidence is graded. We tell you how strong a finding is, not just what it was.
- Human review. Summaries may be drafted with software assistance, but nothing is published without human review.
- No promotion. We don't sell treatments or endorse any clinic, product or provider.
- Not medical advice. This site is educational. Talk to a qualified health professional about your own situation.
How we rate evidence
Every study, condition and substance on the site uses the same four-level scale, modelled on GRADE, the system medical guideline panels use to rate evidence. A rating describes how confident we can be in a finding, not whether a treatment is good or bad.
- High
- Multiple large, well-controlled trials agree.
- Moderate
- At least one good randomised trial, or several smaller consistent ones.
- Low
- Small, open-label or short trials. Promising but uncertain.
- Very low
- Case reports, surveys, animal or early data. Treat as a hypothesis.
