Authorities say 17 people are facing charges following raids earlier in the week at two medical marijuana facilities in Oakland County where authorities say illegal drug sales were taking place.
Arraignments were held Friday at two area courts.
The raids were Wednesday at Clinical Relief in Ferndale and Everybody's Cafe in Waterford Township, and followed an undercover investigation. Police say private residences in Oakland and Macomb counties also were raided.
Michigan voters approved medical marijuana use in 2008.
Oakland County Sheriff Michael Bouchard says the cases illustrate abuses of Michigan's medical marijuana law. Defendants and their attorneys say those arrested were legally distributing medical marijuana.
