Ohio legalized adult-use cannabis in 2023, then rewrote parts of the law in 2026. Here’s what’s different, and what’s still ahead.
What changed in March
Senate Bill 56 took effect on March 20, 2026. It merged the medical and adult-use programs under one regulator, the Division of Cannabis Control, and capped dispensaries at 400 statewide. Adults 21 and older can still buy, possess, and grow cannabis within the legal limits.
Rules worth knowing
- Buy local. Cannabis must come from an Ohio dispensary or a legal home grow. Bringing it home from another state is now a crime, even if it was legal where you bought it.
- No public use. Smoking or using cannabis in public spaces is banned.
- Open containers. In a vehicle, cannabis is treated much like open alcohol.
- Hemp moved indoors. Intoxicating hemp products, including delta-8 and many THC drinks, can only be sold through licensed dispensaries.
What about December?
Ohio’s own hemp rules already started in March. The big December date is federal: a new national limit on hemp THC is now set for December 11. Ohio’s governor also vetoed a plan that would have let 5 mg THC drinks stay on shelves through the end of 2026, so that grace period never took effect.
Rules are changing quickly, so check the Ohio Division of Cannabis Control for the latest. This is general information, not legal advice.
