Cannabis in Michigan is legal for both medical and adult use.

Michigan legalized cannabis for medical use in 2008 through the Michigan Compassionate Care Initiative. The state later legalized the adult use of cannabis in 2018 through the Regulation and Taxation of Marijuana Act.

Within Michigan’s adult use framework adults 21+ may possess up to 2.5 ounces of cannabis flower, or 15 grams of cannabis concentrate. Adults may possess up to 10 ounces of cannabis flower within their home and may grow up to 12 plants within their home. Within the medical framework patients may possess up to 2.5 ounces and up to 12 plants kept in a locked facility.
