Adult-use stores continue to open; expungement bill awaits Senate action 

Last update: January 13, 2020


On December 1, a little over a year after voters approved Prop 1 to end marijuana prohibition, legal marijuana businesses initiated sales to adults 21 and older in Michigan. Reports indicate that consumers purchased more than $1.6 million worth of products in the first week. Regulators, however, received criticism for not ensuring an adequate supply of marijuana remains for medical patients.

In November last year, legislators in Michigan’s House of Representatives passed a package of bills designed to expand access to expungement, including for an estimated 235,000 residents with low-level marijuana convictions on their records. The Senate is expected to vote on the legislation soon. If approved, the proposals would go to Gov. Gretchen Whitmer, who has expressed strong support for clearing marijuana records in the past.  

If you live in Michigan, take action by contacting your state senator and urging them to support expungement for marijuana convictions. 

Previously in 2019, Gov. Whitmer issued an executive order establishing the Marijuana Regulatory Agency within the Michigan Department of Licensing and Regulatory Affairs. The new agency released regulations to steer the implementation of the 2018 voter-approved law that legalized marijuana for adults 21 and older. 

The rules include several forward-thinking provisions, including the creation of licenses for on-site cannabis consumption areas and temporary events, so long as they are permitted by the local town or city government. The guidelines also address how the agency will work to promote participation in the cannabis industry by communities that have been disproportionately harmed by marijuana prohibition.

Michigan becomes the 10th state to legalize marijuana for adults!


In November 2018, Proposal 1 prevailed with 55.9% of the vote, making Michigan the 10th state to legalize marijuana for adults and the first state to do so in the Midwest. In the face of a last minute spending blitz by the opposition, the Yes on 1 campaign overcame a barrage of dishonest attack ads to secure victory by a 12-point margin.

Marijuana Policy Project Deputy Director Matthew Schweich, who served as campaign director for the Yes on 1 campaign, expressed his thoughts on the significance of this win:

“The passage of Proposal 1 is a major milestone for marijuana policy reform in the U.S. Michigan will be the first state in the Midwest to end marijuana prohibition and replace it with a system in which marijuana is regulated for adult use. Adults will no longer be punished for consuming a substance less harmful than alcohol, and rather than having to resort to the illegal market, they will be able to access it safely and legally from licensed businesses. In addition to the public health and safety benefits associated with regulating marijuana, the state will have a significant new stream of tax revenue. Michigan is going to demonstrate that regulating marijuana works, and it will set a strong example for other states in the region and around the country.”

The Michigan Medical Marihuana Program


In 2008, 63% of voters approved a medical marijuana measure spearheaded by MPP. Like other medical marijuana laws that passed prior to Pres. Barack Obama’s election (which led to the federal government adopting a hands-off approach on well regulated medical marijuana programs), Michigan’s original law provided clear protections for patients and caregivers, but did not establish regulations for the businesses that made medical marijuana available to them.

As the population of patients in Michigan grew, the business community serving them also grew. Unfortunately, Michigan’s lack of regulations led to years of harm.

In 2016, lawmakers passed three bills that together overhauled the state’s medical marijuana program. While an improvement in many ways, it was not without its controversies, particularly for those businesses that were operating since voters approved MPP’s medical marijuana initiative in 2008.
