Businesses can’t sell pot, the Michigan Supreme Court said in a pivotal ruling that should close all medical marijuana dispensaries in the state.

In a 4-1 ruling released Friday, the high court upheld a 2011 state Court of Appeals ruling that said patient-to-patient sales of marijuana are illegal under the state’s medical marijuana law.

Enforcement since the appeals’ court decision has depended on the attitudes of local police and sheriff’s agencies.

Marijuana dispensaries can be considered a “public nuisance,” according to the Supreme Court’s opinion.

The 4-1 decision is the most significant court ruling since voters approved medical marijuana 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.
