Pot use becomes legal in Michigan today

LANSING — Marijuana will become legal for adult recreational use in Michigan today when Proposal 1 officially takes effect. The initiative was approved by 56 percent of voters in the November midterm election.

Proposal 1 allows adults 21 and older to possess and transport up to 2.5 ounces of marijuana, including up to 15 grams in the form of marijuana concentrate. It also allows them to grow up to 12 marijuana plants and possess up to 10 ounces of marijuana in their residence, as well as any marijuana that was grown on the premises. State officials are in the process of establishing a regulated system of commercial marijuana cultivation and sales, which is expected to commence in 2020.

Michigan will be the 10th state in which marijuana possession is legal for adults 21 and older. It is the ninth state to authorize a system for regulating commercial marijuana cultivation and sales for adult use. Marijuana possession is also legal for adults in the District of Columbia, and the U.S. territory of the Northern Mariana Islands enacted a law in September to legalize and regulate marijuana for adult use.
