A bill for an act relating to the controlled substance crystalline polymorph psilocybin.

This bill removes the pharmaceutical form of psilocybin (specifically COMP 360, a crystalline polymorph) from Iowa's Schedule I list of controlled substances once approved by the U.S. Food and Drug Administration (FDA). It would make it legal to prescribe, distribute, and market this FDA-approved pharmaceutical version, but only after federal rescheduling under the Controlled Substances Act. The bill does not affect natural psilocybin or other forms of the substance, which remain illegal under current law. It directly impacts medical providers and pharmaceutical companies seeking to offer this specific FDA-approved treatment.
