Psychedelic Readiness Index
About the Index
Last reviewed 11 November 2026
A Note from Tony Greenberg
“Here is what I want you to know before you go one click further. Most of these medicines I have never touched. Some of them I probably never will. What I have done is spent the better part of three decades watching this field from the inside... the researchers, the healers, the disasters, the quiet miracles that never made the news. This index is a synthesis of all of that. It exists because I have seen what happens when someone walks into a ceremony with no map and no container and no one who actually knows what they are doing. This is the map. Where you go from here is completely and entirely up to you.”
— Tony Greenberg, Impact Futurist & Investor in Consciousness Medicine
Not a Doctor. Not a Dealer. Not Reddit.
The Psychedelic Readiness Index is built from decades of research, clinical literature, harm reduction work, and conversations with people who have actually been in the room. It is not medical advice, not a prescription, and not a substitute for a real conversation with a real healthcare professional who knows your history.
What This Is ... And What It Is Not
- Not a doctor. Not a therapist. Not a shaman. We are none of those things and we are not pretending to be.
- The database brings together clinical literature, harm reduction resources and practitioner accounts. The quality and completeness of the evidence vary by entry.
- Not a recommendation. Nothing in here says you should do anything. It says here is what is known, here is what the research shows, here is what experienced practitioners report.
- A synthesis. Built from clinical literature, DanceSafe, Zendo Project, MAPS, ethnobotanical research, and the kind of conversations that happen when people stop performing and start being honest.
- A starting point. Not a finish line. Use this to have better conversations with qualified professionals, not to skip them.
What the score can tell you
The index compares your answers with profiles in a curated database. These profiles can bring a question into focus. A score cannot establish safety, predict benefit or harm, diagnose a condition, or tell you which substance or dose to take.
Talk to your psychedelic council, the people you trust for support and perspective. Bring medical questions, your health history and your full medication list to a licensed clinician familiar with psychedelics. Discuss any medication change with your prescriber first.
Profiles and research can be incomplete. The same score can describe people with very different risks. The index offers neither medical clearance nor a diagnosis.
