The substance index
Four families.
Researched, not romanticized.
Each guide pairs effects, onset, and duration with honest difficulty ratings and harm-reduction context. Nothing here is a recommendation to use — it is information for people who will explore regardless, so they can do it more safely.
Choose a family
46 documented varieties across four families.
- 01 Psilocybin The most documented path, from gentle introductions to profound, ego-dissolving doses.
- 02 Ketamine Dissociative and clinically studied — where context, dose, and setting matter more than almost anything else.
- 03 Mescaline Peyote, San Pedro and Peruvian torch — long, deliberate, deeply ceremonial experiences measured in hours.
- 04 Ayahuasca A potent traditional brew with real medication-interaction risks — where preparation is the whole safety margin.
