When talking about Michigan marijuana laws, the incident at Ann Arbor is sure to come up. Many believe that a marijuana-related arrest in this college town back in the ’70s prompted a change in its municipal possession laws. This in turn may have influenced marijuana law reforms in other municipalities and even the whole state. 

Today, recreational marijuana is legal in the Great Lake State. Since 2018, Michigans have been able to enjoy pot whether from the dispensary or their own plants. The state also has some of the most generous home growing laws of all weed states. However, this seems to be posing a problem for commercial sales as Michigan has reportedly seen declining sales in the last six months. It is suspected that this is because home growers may be taking sales away from dispensaries.

So, just how generous are Michigan’s home cultivation laws? Can it give pot lovers a good enough reason to move? Let’s find out.

Overview of Cannabis Growing Laws in Michigan

Colorado and California frequently get mentioned when talking about marijuana in the US but Michigan may very well have the best weed laws in the land. 

  • All Michigan residents aged 21 years and older may cultivate in their homes up to 12 plants for personal use.
  • The cultivation limit for medical marijuana is the same but a caregiver can grow for up to 5 patients.
  • Growers should tend their cannabis plants in a secured area away from public view.

This was last updated in June 2020. We will be updating this guide with new developments that may come out.

12 plants are a lot, even compared to other pioneering weed states. Also, the law does not specify how many of these plants can be mature at a given time. In addition to this, carrying up to 2.5 oz and/or keeping up to 10 oz at home carries no penalties. It gets even better…

Punishments for Violating Michigan Home Grow Laws

There’s really no good reason to exceed the 12 plant limit. However, the punishment for doing so is not much of a deterrent:

  • Growing more than 12 up to 24 plants for personal use is a civil infraction punishable by a maximum fine of $500 and forfeiture of the marijuana, but no jail time. 
  • Second and third offenses get a maximum fine of $1000 and $2000, respectively, as well as forfeiture of the marijuana, but still no jail time.

Unbelievably enough, it’s possible to avoid jail time for growing 25 or more plants if it cannot be proven that the violation was was “habitual, willful and for a commercial purpose”. However, if the intent to distribute or sell can be proven, anything over 12 up to 20 plants will be considered a felony. This is punishable with imprisonment for a maximum of 4 years and/or a fine of up to $20,000.00. 

History of marijuana in Michigan

Michigan’s journey towards legalization may have started in the ’60s when activist John Sinclair got arrested for possessing two joints. Sinclair was then given an unreasonably harsh sentence of 10 years which received international attention. Thousands of people protested Sinclair’s sentence, including John Lennon, and this led the city to enact some of the most lenient possession laws in the US. 

While it took a few more decades for a number of cities to decriminalize marijuana prior to statewide legalization, the incident at Ann Arbor was definitely instrumental in pointing Michigan’s marijuana policies in the right direction.

It was in 2008 when the Michigan Compassionate Care Initiative was approved allowed registered cardholders to grow up to 12 plants, which is twice the limit in other pro-cannabis states. Oddly enough, it wasn’t until 2016 that a bill allowing medical marijuana dispensaries was signed.

The move towards legalization of recreational marijuana began in 2017 when proponents submitted 365,000 signatures for the 2018 ballot. On November 6, 2018, Proposal 1 got approved by a 56–44 margin, making Michigan the first Midwest state to allow the use of recreational marijuana.

Growing medical and recreational marijuana in Michigan

In a nutshell, all Michigan residents aged 21 and older may grow up to 12 cannabis plants at home. This limit is both for medical or recreational purposes. 

Why then would patients want to bother getting a medical marijuana card? Well for one, it allows minors with debilitating conditions to use marijuana. Patients and caregivers also get to enjoy higher possession and purchasing limits, but lower taxes under Michigan marijuana laws.

Like most other weed states, a patient must have a debilitating medical condition to be eligible. After securing the necessary documents listed below, you may proceed to apply either online or by mailing your application. 

  • Completed application form for Registry Identification Card. (if submitting by mail)
  • A copy of the designated caregiver’s ID. This can be a state-issued driver’s license or personal ID card.
  • Copy of proof of Michigan residency. This can be a Michigan driver’s license, personal ID card, or signed voters registration. 
  • Physician certification form. 

Minor applications will require the following:

  • Completed minor application form. (if submitting by mail)
  • A copy of the parent or legal guardian’s Proof of Michigan Residency. 
  • A copy of proof of parentage or legal guardianship. This can be a birth certificate, court order, etc.

The registration fee is only $40. You can pay via credit card, checks, or money orders. Patients who wish to add a caregiver may do so online or by mailing a completed Add or Change Caregiver Amendment form. Those who want to apply as a caregiver must not have a felony conviction involving illegal drugs, a violent felony, or any felony within the past ten years.
