Cannabis in Ohio

Cannabis in Ohio is legal for recreational use. Issue 2, a ballot measure to legalize recreational use, passed by a 57–43 margin on November 7, 2023. Possession and personal cultivation of cannabis became legal on December 7, 2023, with the first licensed sales yet to occur under the law. Prior to legalization, Ohio decriminalized possession of up 100 grams in 1975, with several of the state's major cities later enacting further reforms.

Medical use was legalized in 2016 through a bill passed by the state legislature. The first licensed sales of medical cannabis began on January 16, 2019.
