About Psychedex
Psychedex is an open-access research platform and encyclopedia focused on altered states of consciousness. It documents psychoactive substances, practices, effects, and frameworks for understanding these experiences, with an emphasis on open science, harm reduction, and cognitive freedom. Its searchable indexes cover more than 295 substances, 82 practices, 255 effects, and 483 concepts.
Entries present information such as dosage, duration, effects, toxicity, pharmacology, interactions, and potential risks, supported by citations and evidence ratings. Psychedex also offers tools and resources including an interaction checker, reagent guide, emergency protocols, recovery information, and guidance for reading substance profiles. Content is reviewed by humans before publication; AI may assist with drafting and citations, while reviewers verify safety-critical information.
The platform includes community experience reports and a record of editorial changes, with opportunities to contribute. Psychedex describes its material as educational information, not a substitute for professional medical advice, diagnosis, or treatment. It is designed to help readers explore altered states with clearer, evidence-informed context and attention to safety
