What is Michigan Proposal 1?

Proposal 1 legalizes the possession and use of marijuana for recreational purposes for residents 21 years or older. The measure creates an excise sales tax of 10 percent, which is levied on marijuana sales at retailers and microbusinesses. Revenue from the tax is allocated to local governments, K-12 education, and road and bridge maintenance. Proposal 1 also legalizes the cultivation, processing, distribution, and sale of industrial hemp. Municipalities are allowed to ban or limit marijuana establishments within their boundaries. It was approved by Michigan voters on November 6, 2018 and went into effect on December 6, 2018.

This act does not authorize:

  • people to operate vehicles or other machinery under the influence of marijuana
  • butane extraction in residential property
  • possession in schools
  • consumption in a place prohibited by the property owner
  • consumption in public
  • marijuana edibles that can appeal to children
