What’s different in Michigan
Michigan voters made adult-use cannabis legal in November 2018 (Proposal 18-1). One state agency, the Cannabis Regulatory Agency (CRA), licenses adult-use businesses and medical marijuana facilities. It also runs the medical marijuana patient registry.
Cities and towns can ban licensed cannabis businesses or limit how many there are. Residents can also petition to put that question on the local ballot. Using cannabis in a public place is against state law, unless a city or town has allowed a designated area that people under 21 can't enter.
Delta-8 THC counts as marijuana in Michigan. Since October 11, 2021, businesses need a state marijuana license to sell it. CRA warns that most delta-8 is made from hemp CBD by a chemical process and may not be tested.
Licensed does not mean risk-free. Licensed products must pass lab tests before sale, and CRA posts recall notices when products are pulled.
