Proposal 1 was approved by 63% of voters on November 4, 2008. Effective December 4, 2008, Proposal 1 protects patients' use, possession, and cultivation of cannabis. Qualifying conditions include cancer, HIV/AIDS, hepatitis C, Crohn's disease, ALS, Nail Patella Syndrome, glaucoma, alzheimer's, severe and chronic pain, cachexia, severe nausea, seizures, or severe and persistent muscle spasms. Michigan's Health Department may approve additional conditions. Physicians can recommend cannabis via a written recommendation.
Under Proposal 1, patients or caregivers are allowed to cultivate up to 12 plants in an enclosed, locked facility and may have up to 2 ½ ounces at any time. A confidential state run patient registry has been established, which issues cards to qualifying patients and caregivers. Caregivers must be 21 years old or older and never have been convicted of a felony. Patients may have one caregiver at a time but a caregiver may assist up to five patients at a time.
Michigan allows for reciprocity to any patient who has a state registered ID card or its equivalent from other medical cannabis states.
