Psychedelic Wiki
An encyclopedic guide to psychedelic substances, their history, and the science behind them.
This wiki is a harm-reduction and education resource. Psychedelics are powerful substances with long histories of human use — for healing, for ceremony, for exploration, and sometimes for recreation. Understanding them clearly is more useful than fearing them.
Note: This wiki is for educational purposes. Nothing here constitutes medical advice. Many of these substances are controlled in most jurisdictions.
