DETROIT (AP) -- The Michigan Supreme Court says users of medical marijuana can't buy it at pot shops.
The 4-1 decision Friday is the most significant court ruling since voters approved marijuana for certain illnesses in 2008. It means the state's 126,000 approved users must grow their own pot or have a state-licensed caregiver grow it for them.
The state appeals court declared dispensaries illegal in 2011, but enforcement has depended on the attitudes of local authorities. Some communities took a hands-off approach while waiting for the Supreme Court to make the ultimate decision.
The case involves a Mount Pleasant dispensary that allowed medical-marijuana users to sell pot to each other. Owners took as much as a 20 percent cut of each sale. Isabella County shut it down as a public nuisance.
