If you don’t think medical marijuana means some serious coin, just ask the Michigan state government.

Medicinal weed is turning into a real windfall for Michigan, with nearly $10 million in revenue collected — nearly double the cost of the program, according to a new report, which covers the state’s last budget year, ending September 30, 2012, reports The Associated Press.

Medical marijuana applications cost $100 in Michigan. Caregivers who grow cannabis for others must also pay a fee.

The number of state-registered marijuana patients seems to be increasing across the board, with results ranging from Kent and Ottawa counties, up at least 20 percent, all the way to Cass County in the southwestern corner of the state, up 56 percent.

Michigan voters approved the state’s medical marijuana law with an overwhelming 62 percent majority in 2008. Every single county in the state voted yes on legalizing medical marijuana.

Many cops, reluctant to accept marijuana‘s new legal status, claim the law is “poorly written” as an excuse to keep busting patients who are trying their damnedest to comply with it. It got so bad, in fact, that the American Civil Liberties Union (ACLU) broke out a team of lawyers to sue several Michigan cities over their anti-marijuana policies.

Enforcement varies widely across the state, with some locales such as Oakland County seeing a strict interpretation of the law, thanks to notoriously anti-pot Sheriff Michael Bouchard.

“This is Michigan, not some Cheech and Chong movie,” Bouchard infamously said in 2010.
