Licensed storefronts are now eligible to engage in retail cannabis sales to adults. The first adult-use sales began on Sunday, December 1.

Michigan voters last year approved a statewide initiative authorizing state officials to regulate the plant’s production, use, and sale.

In October, state regulators began accepting applications from medical cannabis dispensaries wishing to also engage in adult-use marijuana sales. As of this week, six storefronts — including four retailers in Ann Arbor — are licensed to sell cannabis to adults. Several other businesses have applications pending. Nonetheless, a statewide rollout of marijuana-related business is anticipated to be slow because many communities have passed local ordinances prohibiting adult-use establishments.

On January 1, Illinois will become the eleventh state to permit adult marijuana use.
