ProhibitedSchedule I federally
Psilocybin is illegal in Oklahoma: it is a Schedule I controlled substance under 63 O.S. 2-204, and the House-passed psilocybin research bills of 2022 and 2023 never became law.

- Oklahoma's 2026 Oklahoma Breakthrough Therapy Act (HB 3834) directs the State Department of Health, subject to available funds, to contract with a drug developer to support multistate clinical trials seeking FDA approval of ibogaine; it does not cover psilocybin and takes effect 1 November 2026.
