Psilocybin law in Rhode Island

Illegal Checked 26 October 2026

Psilocybin is illegal in Rhode Island: it is a Schedule I controlled substance under R.I. Gen. Laws 21-28-2.08, and every bill to allow personal possession or home cultivation since 2023 has failed to become law.

Psilocybin is a controlled substance with no lawful route for retreats or personal use. Some of these states fund research or trials. A summary of published sources, not legal advice.

Source status: Prohibited. Psilocybin remains a Schedule I drug under US federal law.
