An Iowa House committee has unanimously approved a Republican-led proposal to create a state-regulated therapeutic psilocybin program for adults with PTSD.
The bill, HF 620, from Rep. John Wills (R), passed the House Ways and Means Committee on a 23–0 vote at a hearing Thursday.
If enacted into law, it would allow up to 5,000 patients in the state to legally access psilocybin produced in-state by licensed entities. Administration sessions would need to be supervised by registered facilitators—mostly medical professionals—who would need to complete state-specified psilocybin education.
Psilocybin providers would need to be doctors, advanced nurse practitioners, advanced practice nurses, psychologists or social workers who complete psilocybin continuing education requirements, register with the state and pay a registration fee.
Administration sessions themselves would need to be at registered clinical locations and would need to be video recorded. Those records would need to be available for inspection by state officials upon request.
The psilocybin itself would be produced by state-licensed establishments. Local governments could not outright ban those facilities, nor could they deny them appropriate licenses based merely on the fact that psilocybin violates federal law.
Notably, a licensed psilocybin production facility could be co-located with one of the state’s few licensed medical cannabis producers—known in Iowa as medical cannabidiol producers—and the bill says regulators may grant psilocybin licensing preferences to those existing cannabis producers. Facilities couldn’t be located within 1,000 feet of a community location or 500 feet of a residential area.
Only people 21 and older and without “a misdemeanor for drug distribution or any felony” could work at psilocybin producers, and licensees themselves would face background checks.
Up to four independent testing labs could be licensed under the bill, and the state could also establish its own lab.
License applications would be accepted beginning July 1, 2026.
To oversee the system, the legislation would create a state Psilocybin Production Establishment Licensing Board under the Iowa Department of Health and Human Services (HHS).
Appointed by the director of that department, the board would include a member of the public with knowledge of psilocybin, a member with knowledge and experience in the pharmaceutical or nutraceutical manufacturing industry, a law enforcement member, a university chemist or researcher with experience in manufacturing, a member who has a background in fungus or mushroom cultivation and processing.
