Sponsored by the Michigan Coalition for Compassionate Care, the Michigan Medical Marihuana Act would amend state law to allow authorized patients to use cannabis therapeutically under a doctor’s supervision. Backers of the plan gathered over 300,000 signatures from Michigan voters to place the measure on the upcoming ballot.

Under Michigan law, state lawmakers may preemptively enact the measure, but are unlikely to do so.

Since 2004, five Michigan cities – Ann Arbor, Detroit, Ferndale, Flint, and Traverse City – have each enacted municipal initiatives endorsing the medical use of marijuana.

If enacted by the voters, Michigan will become the thirteenth state since 1996 to authorize the legal use of medical cannabis, and the ninth state to do so by voter initiative.
