Marijuana is the No. 1 illicit drug of choice in Michigan, and by a variety of measures, marijuana use is increasing.
Consider:
- In 2014-15, 15% of Michiganders used marijuana at least once in the previous year, up from 12% in 2008-09, according to the federal Substance Abuse and Mental Health Services Administration.
- About 10% of Michiganders used marijuana in the previous month in 2014-15, comapred to 7.5% in 2008-09, based on SAMSA estimates.
- Almost 220,000 Michigan patients had a medical marijuana card in 2016, a 76% increase from 2012.
- About 9.3% of all 2015 arrests in Michigan involved marijuana, up from 7% in 2008.
Michigan voters approved use of medical marijuana in 2008. There currently is a petition drive under way to put a proposal on the November 2018 ballot to legalize use of recreational marijuana in Michigan.
Below is a look at the available data about marijuana use in Michigan.
That data shows there are 218,556 patients with a medical marijuana card as of Sept. 30, 2016, plus 38,057 caretakers with a card so they can obtain marijuana for a designated patient. The number of patient cardholders has increased 76 percent since 2012, the data shows.
The big caveat about the above chart: The decline in 2014 reflects the initiation of a two-year registry program, meaning the 2014 numbers show only some cardholders because previous registrants did not have to re-register during that time period.
Montmorency County in the northeast Lower Peninsula has the highest rate of residents with a medical marijuana card and Ottawa County has the lowest. You can click on a county in this interactive map to see the underlying data.
New applications for medical marijuana cards increased 70% between 2012-13 and 2015-16. About 86% of the applications were approved, and it took about 12 days on average to process an application.

About 80% of Michigan medical marijuana cards are granted to treat “severe and chronic pain.” The above chart shows the 9 most common qualifying conditions for medical marijuana cards. The percentages add up to more than 100 because some patients have more than one condition.
In fiscal 2016, a total of 1,759 physicians wrote medical marijuana prescriptions, up 23% from the previous year.
