Is psilocybin legal in Indiana?

No, except through research. Psilocybin is illegal for the general public in Indiana, but the state funds or authorizes clinical studies — enrolling in one is the only lawful route.

As of 30 August 2026, psilocybin remains a Schedule I controlled substance under the federal Controlled Substances Act. It has not been approved by the FDA and has not been rescheduled by the DEA. A state program protects you under state law only.

What the law says in Indiana

Illegal for residents, but Indiana created a therapeutic psilocybin research fund and appropriated money for clinical trials. The only lawful route is enrolling in a funded study.

Key law: HB 1259 (2024); HB 1166 (2025 appropriation).

If you are looking for legal access

The nearest legal option to Indiana is Colorado

Colorado runs a licensed supervised-access program with no residency requirement, so people do travel for sessions. Expect roughly $1,000–$3,500 out of pocket — no insurer covers it.

You cannot lawfully bring psilocybin back to Indiana. Possession outside the licensed system is a crime in Colorado too, and carrying it across state lines is a federal offense.
