The changes affect doctors, 131,000 medical marijuana patients and 27,000 caregivers, who grow the drug for patients.
These new changes were passed during the state legislature's lame-duck session last year. A super majority in the legislature approved the changes that affect the Medical Marijuana Act voters approved in 2008.
Changes for patients
Patients will have to prove they live in Michigan. They can do that through state ID, driver’s license, or voter’s registration card. Their medical marijuana cards will be good for two years instead of one.
