Groups in Michigan backing medical marijuana and pushing for broader legalization of the drug hope to send a message by spending $2 bills.
A three-week effort begins Wednesday to demonstrate their economic clout, and they're asking supporters to spend at least one of the typically less-used $2 bills for every cash purchase.
On Tuesday, 45-year-old Steven Greene of South Lyon picked up $200 in $2 bills from a credit union in the Detroit suburb of Southfield. Greene is a state-registered user of medical marijuana and a caregiver licensed by the state to grow medical marijuana for others.
Michigan voters approved marijuana for some chronic medical conditions in 2008, but the Supreme Court ruled in January that medical marijuana dispensaries aren't allowed.
