Michigan Marijuana Laws: Possession Limits, Home Growing and Legal Sales in 2026

Marijuana is legal in Michigan for adults 21 and older, including possession, purchases from licensed retailers, home cultivation and marijuana delivery. Michigan also operates a separate medical marijuana program for registered qualifying patients.

Adults may possess up to 2.5 ounces of marijuana outside their home, including no more than 15 grams of marijuana concentrate. At home, adults may possess up to 10 ounces, plus marijuana produced by plants legally grown on the property.

Michigan also has one of the country’s more generous recreational home cultivation laws, allowing up to 12 marijuana plants at a residence for personal use.

Michigan voters approved recreational marijuana legalization through Proposal 1 in November 2018, and licensed adult-use sales began in December 2019.

Michigan Marijuana Laws at a Glance

Is Recreational Marijuana Legal in Michigan?

Yes. Recreational marijuana is legal in Michigan for adults 21 and older.

Michigan voters approved the Michigan Regulation and Taxation of Marihuana Act in November 2018. The law took effect December 6, 2018, legalizing adult possession and home cultivation.

Licensed recreational marijuana sales began in December 2019.

Adults do not need a medical marijuana card to purchase marijuana from a licensed adult-use retailer.

How Much Marijuana Can You Possess in Michigan?

An adult 21 or older may possess up to 2.5 ounces of marijuana outside their residence.

Of that amount, no more than 15 grams may consist of marijuana concentrate.

At a person’s residence, Michigan law allows possession of:

• Up to 10 ounces of marijuana
• Marijuana produced by plants legally cultivated on the premises
• Up to 12 marijuana plants

Marijuana exceeding 2.5 ounces inside the residence must generally be stored in a container or area equipped with locks or another functioning security device.

Marijuana produced by legally grown plants at the residence is not subject to the ordinary 10-ounce home possession cap.

How Much Marijuana Can You Buy in Michigan?

An adult 21 or older may purchase up to 2.5 ounces of marijuana in a single transaction from a licensed adult-use retailer.

No more than 15 grams may be marijuana concentrate.

Michigan retailers may also sell up to three immature marijuana plants to a customer in a single transaction.

The amount purchased still counts toward the individual’s legal possession limits after leaving the store.

Can Tourists Buy Marijuana in Michigan?

Yes.

Michigan does not require recreational customers to be state residents. Any adult 21 or older may purchase marijuana from a licensed adult-use retailer with acceptable proof of age.

Visitors are subject to the same 2.5-ounce possession limit that applies to Michigan residents.

However, marijuana purchased in Michigan cannot legally be transported across state lines, even when traveling to another state where recreational marijuana is legal.

Can You Grow Marijuana at Home in Michigan?

Yes.

Adults 21 and older may cultivate up to 12 marijuana plants at their residence for personal use.

Importantly, the limit is 12 plants per residence, not 12 plants per adult. A house with multiple adults 21 or older is still limited to 12 recreational plants on the premises at one time.

Plants must:

• Be grown for personal use
• Not be visible from a public place without the use of binoculars, aircraft or other optical aids
• Be kept within an enclosed area equipped with locks or other functioning security devices

Michigan therefore allows substantially more recreational plants than many other legal-marijuana states.

Property owners may prohibit marijuana cultivation on property they own or control.

How Much Home-Grown Marijuana Can You Keep in Michigan?

Adults may keep marijuana produced by plants they legally cultivated at their residence even when the amount exceeds Michigan’s ordinary 10-ounce residential possession limit.

The law specifically protects possession of marijuana produced by plants cultivated on the premises.

Marijuana exceeding 2.5 ounces in the residence must generally be secured in a locked container or area.

Home-grown marijuana is for personal use. Selling it without the required state license is not protected by Michigan’s home cultivation law.

Is Medical Marijuana Legal in Michigan?

Yes.

Michigan voters approved the Michigan Medical Marihuana Act in 2008, making Michigan one of the earlier states to establish a comprehensive medical marijuana program.

The program remains in effect alongside recreational legalization.

Registered qualifying patients may possess marijuana, purchase from licensed medical provisioning centers and either cultivate marijuana themselves or designate a registered primary caregiver to grow on their behalf.

Patients must obtain certification from an authorized Michigan physician and register through the Michigan Medical Marijuana Program.

What Conditions Qualify for Medical Marijuana in Michigan?

Michigan recognizes numerous qualifying conditions, including:

• Cancer
• Glaucoma
• HIV
• AIDS
• Hepatitis C
• Amyotrophic lateral sclerosis
• Crohn’s disease
• Agitation of Alzheimer’s disease
• Nail-patella syndrome
• Post-traumatic stress disorder
• Obsessive-compulsive disorder
• Arthritis
• Rheumatoid arthritis
• Spinal cord injury
• Colitis
• Inflammatory bowel disease
• Ulcerative colitis
• Parkinson’s disease
• Tourette syndrome
• Autism
• Chronic pain
• Cerebral palsy

A patient may also qualify when a chronic or debilitating disease or its treatment causes:

• Cachexia or wasting syndrome
• Severe and chronic pain
• Severe nausea
• Seizures, including those associated with epilepsy
• Severe and persistent muscle spasms, including those associated with multiple sclerosis

Michigan periodically allows petitions seeking the addition of other qualifying conditions.

How Much Medical Marijuana Can a Patient Possess in Michigan?

A registered qualifying patient may generally possess up to 2.5 ounces of usable marijuana.

A patient who is authorized to cultivate marijuana may also possess up to 12 marijuana plants kept in an enclosed, locked facility.

If the patient has designated a registered primary caregiver to cultivate on the patient’s behalf, the caregiver rather than the patient is generally responsible for those plants.

Michigan’s medical protections operate separately from the adult-use law.

How Much Medical Marijuana Can Patients Buy?

Licensed medical marijuana provisioning centers may sell a registered qualifying patient up to 2.5 ounces of marijuana or its equivalent per day.

A patient is also subject to a monthly purchasing limit of 10 ounces during a 30-day period, whether purchases are made directly by the patient or through the patient’s registered primary caregiver.

Retailers use Michigan’s statewide marijuana tracking system to verify medical purchasing limits.

Can Medical Marijuana Patients Grow at Home in Michigan?

Yes.

A registered qualifying patient may cultivate up to 12 marijuana plants for medical use.

Alternatively, the patient may designate a registered primary caregiver to cultivate up to 12 plants on the patient’s behalf.

Medical marijuana plants must be kept in an enclosed, locked facility as required by the Michigan Medical Marihuana Act.

Michigan’s patient and caregiver cultivation system remains in effect despite the legalization of recreational marijuana.

What Are the Benefits of a Michigan Medical Marijuana Card?

Michigan’s medical program still provides several advantages even though recreational marijuana is legal.

Registered patients receive:

• Access to the state’s medical marijuana system
• Medical marijuana protections beginning at age 18, with younger qualifying patients able to participate through a parent or guardian
• Up to 12 medical marijuana plants
• Access to registered primary caregivers
• A medical purchase allowance of up to 2.5 ounces per day and 10 ounces per 30 days
• Exemption from Michigan’s 10% adult-use marijuana excise tax

Medical marijuana purchased from a licensed provisioning center remains subject to Michigan’s 6% sales tax but is not subject to the 10% retail marijuana excise tax imposed on recreational purchases.

The new 24% wholesale marijuana tax that took effect in 2026 is also directed at adult-use marijuana rather than ordinary medical marijuana wholesale transactions.

Does Michigan Accept Out-of-State Medical Marijuana Cards?

Yes.

Michigan provides medical marijuana reciprocity for qualifying visitors with valid medical marijuana credentials issued by another U.S. state, district, territory, commonwealth or insular possession.

A licensed Michigan medical provisioning center may sell marijuana to a visiting qualifying patient when the retailer:

• Verifies the patient’s valid, unexpired medical marijuana card or equivalent credential
• Verifies the patient’s government-issued photo identification
• Ensures the purchase does not exceed Michigan’s medical purchasing limits

This means qualifying visitors can potentially purchase through Michigan’s medical marijuana system rather than being limited to recreational purchases.

Where Can You Use Marijuana in Michigan?

Marijuana generally may be consumed on private property where the property owner allows it.

Public consumption is not legal.

Michigan law specifically does not authorize marijuana consumption in a public place or smoking marijuana on property where the owner, occupant or manager has prohibited it.

Marijuana is also prohibited in certain locations including:

• K-12 school grounds
• School buses
• Correctional facilities
• Federal property

Michigan does allow licensed designated marijuana consumption establishments and temporary marijuana events where on-site use may occur under state and local regulations.

Can You Smoke Marijuana in a Car in Michigan?

No.

Michigan law prohibits consuming marijuana while operating or being in physical control of a motor vehicle.

Smoking marijuana within the passenger area of a vehicle on a public road is also prohibited.

Driving while under the influence of marijuana remains illegal regardless of whether the marijuana was legally purchased or the driver is a registered medical marijuana patient.

Recreational legalization does not provide protection for impaired driving.

Can You Give Marijuana to Another Adult in Michigan?

Yes.

An adult 21 or older may give another adult up to 2.5 ounces of marijuana without receiving payment.

No more than 15 grams of the transferred amount may consist of marijuana concentrate.

The transfer must be genuinely noncommercial. Selling marijuana without a license or disguising a sale as a gift is not protected.

Michigan law therefore allows adults to share marijuana but does not authorize an unlicensed retail market.

Is Marijuana Delivery Legal in Michigan?

Yes.

Licensed marijuana retailers may provide home delivery when authorized to do so under state regulations.

Michigan also allows licensed medical provisioning centers to offer delivery to registered patients.

Importantly, marijuana delivery may occur in municipalities that have opted out of allowing marijuana establishments. State law prevents municipalities from restricting the transportation of marijuana through their jurisdictions.

Consumers should purchase only from businesses licensed through the Michigan Cannabis Regulatory Agency.

Can Local Governments Ban Marijuana Stores in Michigan?

Yes.

Cities, villages and townships may prohibit or limit marijuana establishments within their boundaries.

A municipality may also regulate marijuana businesses through local ordinances governing matters such as zoning and the number of establishments allowed.

Local governments cannot make personal possession or home cultivation illegal when those activities are protected by statewide law.

A municipality also cannot prohibit the transportation of marijuana through the municipality, including lawful delivery.

How Is Recreational Marijuana Taxed in Michigan?

Adult-use marijuana purchased from a Michigan retailer is subject to:

• A 10% marijuana excise tax
• Michigan’s 6% sales tax

Medical marijuana sold by licensed provisioning centers is subject to the 6% sales tax but not the 10% adult-use marijuana excise tax.

Michigan added another major tax to the adult-use industry in 2026.

Beginning January 1, 2026, the state imposed a 24% wholesale marijuana tax on certain first sales or transfers of adult-use marijuana from wholesalers to retail licensees.

The 24% tax is imposed at the wholesale level rather than directly on consumers at checkout. The business responsible for the tax may pass its cost through to the retailer.

The wholesale tax applies in addition to the existing retail taxes.

What Are the Penalties for Possessing Too Much Marijuana in Michigan?

Michigan’s legalization law establishes graduated penalties for possession beyond the legal amount.

For an adult 21 or older, the ordinary legal possession limit outside the home is 2.5 ounces, including no more than 15 grams of concentrate.

A person who possesses no more than twice the amount allowed by the adult-use law generally faces:

• First violation: Civil infraction and a fine of up to $500, plus forfeiture
• Second violation: Civil infraction and a fine of up to $1,000, plus forfeiture
• Third or subsequent violation: Misdemeanor and a fine of up to $2,000, plus forfeiture

Possessing more than twice the amount allowed under the law is a misdemeanor.

However, Michigan’s legalization statute provides that imprisonment generally cannot be imposed for that offense unless the violation was habitual, willful and for a commercial purpose or involved violence.

Different rules apply inside a residence, where an adult may possess up to 10 ounces plus marijuana harvested from plants legally grown on the premises.

What Are the Penalties for Breaking Home-Grow Rules?

Michigan adults may grow up to 12 marijuana plants at a residence.

Cultivating more than the legal amount can trigger the graduated penalties contained in the Michigan Regulation and Taxation of Marihuana Act.

Growing no more than twice the legal plant limit generally results in:

• First violation: Civil infraction, fine of up to $500 and forfeiture
• Second violation: Civil infraction, fine of up to $1,000 and forfeiture
• Third or subsequent violation: Misdemeanor, fine of up to $2,000 and forfeiture

Growing more than twice the authorized amount is a misdemeanor, with imprisonment generally restricted to habitual, willful commercial violations or cases involving violence.

Separate penalties may apply when marijuana cultivation is connected to unauthorized commercial activity.

What Is the Penalty for Public Marijuana Use in Michigan?

Public marijuana consumption is prohibited.

A person who possesses or uses marijuana in a manner not authorized by the adult-use law, while remaining within the law’s quantity limits, may generally face a civil infraction carrying a fine of up to $100 and forfeiture of the marijuana.

Michigan does permit consumption at specifically licensed designated consumption establishments and temporary marijuana events.

What Changed With Michigan Marijuana Laws in 2026?

The most significant statewide marijuana change in Michigan in 2026 was the introduction of a new wholesale tax on adult-use marijuana.

24% Wholesale Marijuana Tax

Michigan’s Comprehensive Road Funding Tax Act took effect January 1, 2026.

The law imposes a 24% excise tax on the wholesale price of certain adult-use marijuana transactions, generally including the first sale or transfer from a marijuana grower or processor to a retail licensee.

The tax is separate from Michigan’s existing 10% adult-use retail excise tax and 6% sales tax.

The wholesale tax is imposed on businesses rather than directly on consumers at the register, although wholesalers may pass the cost through to retailers.

Ordinary medical marijuana wholesale transactions are not subject to the new adult-use wholesale tax.

Marijuana Rule Changes Remain Under Development

Michigan’s Cannabis Regulatory Agency has also been working on a broad revision of the state’s marijuana administrative rules.

After receiving more than 700 suggested changes during an earlier public-comment process, the agency announced in May 2026 that it had made more than 120 changes to its proposed rules and would conduct another public-comment period and hearing.

Those proposals should not be treated as final law until the rulemaking process is completed.

Are THCA, Delta-8 and Hemp-Derived THC Legal in Michigan?

Michigan allows hemp products, but intoxicating cannabinoids are regulated much like marijuana. Delta-8 THC is specifically regulated by the Cannabis Regulatory Agency and cannot legally be sold by businesses that are not properly licensed. (michigan.gov)

Michigan also counts THCA as THC when determining whether cannabis is marijuana. As a result, high-THCA flower that exceeds the state’s 0.3% THC threshold is treated as marijuana rather than ordinary hemp and must be sold through the regulated marijuana market. Adults 21 and older may legally purchase marijuana flower and other approved THC products from licensed retailers.
