Michigan legalized medical marijuana in November, 2008, becoming the 13th state in America to do so.


Under the Michigan Medical Marijuana Act, qualifying patients suffering from a state-approved debilitating condition are allowed to possess up to 2.5 ounces of usable marijuana and usable marijuana equivalents.

According to Michigan law, the following values are equivalent to one ounce of usable marijuana:

  • 16 ounces of marijuana-infused products in solid form

  • 7 grams of marijuana infused product in gaseous form

  • 36 fluid ounces of marijuana-infused product in liquid form

Additionally, qualifying patients are also allowed to possess up to 12 marijuana plants, so long as they are kept in an enclosed, locked facility.

If a qualifying patient specifies a primary caregiver upon registration into the program, then the specified caregiver would be allowed to possess 12 marijuana plants as well as 2.5 ounces of useable marijuana.

Incidental or minute amounts of stems, stalks, seeds and roots are not included in Michigan medical marijuana possession limits.

Purchasing Limits

Under Senate Bill 660 and the Michigan Medical Marijuana Act, patients are not permitted to obtain more than 2.5 ounces of pharmaceutical-grade cannabis. Dispensaries reserve the right to limit sales to a patient based on laws and regulations of the local jurisdiction where the dispensary is located.

Qualifying Patients

The Michigan Medical Marijuana Act specifies qualifying patients as “a person who has been diagnosed by a physician as having a ‘debilitating medical condition.’”

Debilitating medical conditions include:

  • Alzheimer’s Disease

  • Amyotrophic Lateral Sclerosis (ALS)

  • Cachexia/Wasting Syndrome

  • Cancer

  • Crohn’s Disease

  • Glaucoma

  • Hepatitis C


  • Nail Patella

  • Seizures

  • Severe & Chronic Pain

  • Severe & Persistent Muscle Spasms

  • Severe Nausea

  • Any other medical condition approved by the Department of Community Health

In order to be considered a qualified patient who is eligible for the medical marijuana program, a patient must receive written certification from a medical doctor or doctor of osteopathy. The physician must certify that a patient has a debilitating condition and that, in their professional opinion, the patient will receive therapeutic benefits from the medical use of marijuana to treat their symptom(s).


The consumption of medical marijuana by qualifying patients is permitted, so long as the patient follows the provisions set forth under the Michigan Medical Marijuana Act. The consumption of marijuana is only allowed on private property out of view from the public and cannot be consumed in any public place or property.

Driving Under the Influence

Driving under the influence of medical marijuana, or any marijuana for that matter, is strictly prohibited. Driving under the influence of cannabis is treated in similar light to a DUI with alcohol, and violators face steep fines and even jail time as punishment. Our advice? Don’t smoke and drive! There are plenty of ride-sharing options or public transportation choices that will keep you safe and on the right side of the law at all times.

Transporting Marijuana

Transporting medical marijuana in Michigan is legal for qualified patients and caregivers, as long as the marijuana or marijuana-infused products being transported are:

  • In a sealed and labeled package

  • In the trunk of the car

    • If there is no trunk, the marijuana must be in a location that is not readily accessible from the interior of the vehicle

If a patient or caregiver is found in violation of these stipulations, they face a civil fine of up to $250.

Exporting Marijuana

Exporting medical marijuana from Michigan to other states is strictly prohibited and illegal under the Michigan Medical Marijuana Act. Medical cannabis is only for the patient that it was purchased for and therefore cannot be sold, transferred or exported to anyone in or out of the state of Michigan.

Forms of exporting include, but are not limited to, mailing, driving, shipping, flying or boating cannabis across state lines.


Under the Michigan Medical Marijuana Act, it is permissible for qualified patients or caregivers to cultivate up to 12 marijuana plants as long as they are grown in locked, secure and enclosed facility that is not viewable to the public. In order to be fully compliant with the law, the patient or caregiver must possess bot a valid registry identification card and a valid government-issued ID with a photo image.
