One of the most significant legal issues since voters approved medical marijuana is on the docket at the Michigan Supreme Court.
Justices are hearing arguments Thursday about shops known as dispensaries, where people with medical marijuana cards sell homegrown pot to people who don't grow their own.
The state appeals court last year said there's nothing in the 2008 law that allows it. A decision by the Supreme Court could settle one of the biggest challenges for people approved for medical marijuana: How do they get their drugs?
The case involves a Mount Pleasant shop that allowed members to sell marijuana to each other, with the owners taking a 20 percent cut. The appeals court said the shops are illegal, but some communities have ignored them.
