Plain-language guide to Illinois’s psilocybin, MDMA, and psychedelic laws — what’s legal, what isn’t, and what may change.
Illinois has introduced multiple bills addressing psilocybin, including a CURE Act modeled on similar legislation elsewhere. None have passed as of 2026. Psilocybin mushrooms are Schedule I under the Illinois Controlled Substances Act and federal law. No city in Illinois has passed a deprioritization resolution specifically for psilocybin.
As of 2026, Illinois does not have a licensed psilocybin access program. Legal options for residents include:
No. Psilocybin is a Schedule I controlled substance under the Illinois Controlled Substances Act (720 ILCS 570/204). No state-level decriminalization or therapeutic access program has passed. No Illinois city — including Chicago — has passed a deprioritization resolution for psilocybin.
No. Chicago has not passed any city resolution on psilocybin mushrooms. Illinois state law classifies psilocybin as Schedule I, and that applies throughout Chicago.
The CURE Act (Compassionate Use and Research of Entheogens) — filed as SB 3695 and related companion bills — would create a licensed therapeutic access framework for psilocybin and related psychedelics in Illinois. It is modeled on Oregon's Measure 109. As of 2026 it has not passed.
