This Tuesday, Michiganders will go to the polls and decide whether to make their state the 10th in the nation to legalize the adult recreational use of marijuana. If passed, the new law would create a tightly-regulated system akin to the one already in place for alcohol, creating six categories of licensed marijuana businesses in the process: cultivators, processors, testing facilities, secure transporters, retailers, and microbusinesses.

Individual adults aged 21 and over would be allowed to possess up to 2.5 ounces of marijuana and grow up to 12 plants for their own, personal use.

The measure would also legalize the cultivation of industrial hemp, which can be used for the production of food, paper, plastics, and biofuels.

Michigan already has a working medical marijuana law in place, which voters approved in 2008 and expanded in 2016. Although support for more sensible marijuana laws has traditionally been strong in the Wolverine State, pollsters predict the vote on Tuesday to be a close one.
