Michigan voters have passed an initiative to legalize marijuana.

Voters this evening passed Proposal 18-1 into law, making Michigan the 10th state to legalize marijuana. The initiative allows for the possession of up to 2.5 ounces, or up to 10 ounces at a private residence, for those 21 and older. The measure also legalizes the personal cultivation of up to 12 marijuana plants.

The initiative establishes a licensed and regulated system of marijuana retail outlets, which will be supplied by licensed cultivation centers. Marijuana will receive a 10% excise tax in addition to the standard 6% sales tax.

Michigan now joins nine other states that have legalized marijuana for all uses: Washington, Colorado, California, Oregon, Alaska, Massachusetts, Maine, Nevada and Vermont. The latter is the only state that does not authorize marijuana stores.

Below is the official ballot summary of Proposition 18-1 that voters approved:

This proposal would:

Allow individuals 21 and older to; purchase, possess and use marijuana and marijuana-infused edibles, and grow up to 12 marijuana plants for personal consumption.

Impose a 10-ounce limit for marijuana kept at residences and require amounts over 2.5 ounces be secured in locked containers.

Create a state licensing system for marijuana businesses and allow municipalities to ban or restrict them.

Permit retail sales of marijuana and edibles subject to a 10% tax, dedicated to implementation costs, clinical trials, schools, roads, and municipalities where marijuana businesses are located.

Change several current violations from crimes to civil infractions.
