A chain of medical marijuana dispensaries filed a lawsuit in Wayne County Circuit Court Wednesday challenging Detroit’s new recreational marijuana ordinance.

A provision in the ordinance, which was approved last month by the Detroit City Council, doesn’t allow medical marijuana establishments to be eligible to obtain a recreational license for five years. The lawsuit brought by four House of Dank dispensaries — each operating under a unique name — said that wording violates the state’s 2018 recreational marijuana law.

The ordinance, which went into effect April 20, reads: “Commencing on January 1, 2027, any licensees which are holders of one or more licenses to operate a medical marijuana provisioning center in accordance with this article and which have been the holder of such licenses since prior to the effective date of this ordinance, may apply for an adult use retailer license.”

The city’s law department said it had not had a chance to review the complaint and declined to comment Wednesday.

House of Dank, which opened a medical dispensary on Eight Mile in 2015, now has four medical dispensaries in Detroit and four recreational dispensaries elsewhere in Michigan. [Read more at The Detroit News]
