In November 2008, Michigan voters passed the Michigan Medical Marijuana Act. The new state law supports the Ann Arbor City charter by offering protection from state law enforcement for qualifying patients and their assigned primary caregivers under the law that took effect on April 4, 2009. Under the law, a patient with a qualifying condition and a signed statement from an attending physician, can register for an identification card under the Michigan Department of Community Health managed program for legal medical marijuana use in Michigan. After registration, the patient and primary caregiver can legally be in possession of marijuana according to State law. The primary caregiver may provide assistance for using medical marijuana or even be assigned responsibility for cultivating the patient's legally protected maximum of 12 marijuana plants, for a fee.
Like many states, Michigan allows the legal use of medical marijuana. Michigan Initiated Law 1 of 2008—known as the Michigan Medical Marijuana Act—made it legal to grow and use marijuana for debilitating medical conditions. However, you should carry a state-issued medical marijuana registry identification card to notify law enforcement officials that you are authorized under the act to use medical marijuana because of your debilitating medical condition. If you do not have the identification card, you may be arrested for possession by the police and have to use your medical condition as a defense at trial.
