Medical use of cannabis was legalized with the passage of Proposal 1, the Michigan Compassionate Care Initiative, on November 4, 2008.
[5] The measure legalized the possession of up to 2+1⁄2 ounces (71 g) of cannabis for patients with certain medical conditions and the approval of a physician.
[9] In February 2013, the Supreme Court of Michigan ruled that the 2008 initiative did not allow for the operation of medical cannabis dispensaries in the state.
[20] During fiscal year 2021, the state of Michigan collected $175 million from a 10% excise tax on recreational cannabis sales.
That money was given back to counties, towns, cities, and townships, each municipality receiving over $56,000 for every recreational retail location in its boundaries.
