About
TripSit is an online harm reduction organization providing real-time peer support for people having difficult psychedelic experiences, a comprehensive drug interaction checker, and detailed drug information factsheets. The organization operates primarily through its website and online chat channels (IRC and Discord), where trained peer support volunteers are available around the clock.
The TripSit drug combination safety guide is one of the most widely cited free drug harm reduction tools on the internet, mapping the safety of combining different substances and alerting users to dangerous interactions. This tool is routinely referenced by harm reduction organizations, emergency medicine providers, and researchers.
For psilocybin specifically, TripSit provides both factsheet information (onset times, duration, dosage ranges, effects) and real-time chat support for people in difficult experiences — a critical resource for the vast majority of psilocybin users who do not have access to Zendo Project volunteers or clinical sitters.
TripSit's online model allows it to reach users globally, including in jurisdictions where in-person harm reduction services are unavailable or culturally stigmatized.
Why It Matters
TripSit reaches the largest harm reduction audience of any psychedelic organization in the world — serving users who self-select for safety information and peer support outside of any institutional or clinical setting. Its drug interaction checker is the most practically useful harm reduction tool accessible to the average psilocybin user.
