Michigan Drug Laws: Penalties, Charges & Treatment Options

Michigan regulates controlled substances under the Michigan Public Health Code (MCL 333.7101-333.7545), enacted as Act 368 of 1978. The state classifies drugs into five schedules based on their potential for abuse, accepted medical use, and likelihood of dependence. Michigan law distinguishes between simple possession (MCL 333.7403), use of a controlled substance (MCL 333.7404), and manufacture or delivery with intent to distribute (MCL 333.7401), with penalties escalating based on the schedule of the substance and the quantity involved.

Michigan has undergone significant drug policy reform in recent years. In 2018, voters approved Proposal 1, legalizing recreational marijuana for adults 21 and older under the Michigan Regulation and Taxation of Marihuana Act (MRTMA). The state also offers one of the nation's most well-known first-offense diversion programs — the 7411 deferral (MCL 333.7411) — which allows eligible first-time possession offenders to avoid a permanent conviction by completing probation. Michigan also maintains Good Samaritan protections, broad naloxone access, and an extensive drug court system to address substance use disorders through treatment rather than punishment.

For delivery and manufacturing offenses, Michigan imposes steep penalties that increase with the quantity of the substance. Delivery of 1,000 grams or more of a Schedule 1 or 2 narcotic carries a potential sentence of life imprisonment under MCL 333.7401. The state also enhances penalties for offenses committed near schools or involving minors.

Michigan's drug possession penalties are governed primarily by MCL 333.7403 (Unlawful Possession of a Controlled Substance) and MCL 333.7404 (Unlawful Use of a Controlled Substance). Penalties vary significantly based on the drug's schedule classification and the quantity possessed.

Schedule 1 and 2 Narcotics (MCL 333.7403(2)(a))

Possession of Schedule 1 or 2 narcotic drugs (such as heroin, cocaine, fentanyl, or oxycodone) is weight-dependent:

• Less than 25 grams: Felony, up to 4 years imprisonment and up to $25,000 fine.
• 25 to 49 grams: Felony, up to 4 years imprisonment and up to $25,000 fine.
• 50 to 449 grams: Felony, up to 20 years imprisonment and up to $250,000 fine.
• 450 to 999 grams: Felony, up to 30 years imprisonment and up to $500,000 fine.
• 1,000 grams or more: Felony, up to life imprisonment and up to $1,000,000 fine.

Other Controlled Substances (MCL 333.7403(2)(b))

Possession of ecstasy (MDMA) or methamphetamine is a felony punishable by up to 10 years imprisonment and a fine of up to $15,000 under MCL 333.7403(2)(b)(i). Possession of other Schedule 1, 2, 3, or 4 non-narcotic substances is a felony punishable by up to 2 years imprisonment and up to $2,000 fine under MCL 333.7403(2)(b)(ii).

Schedule 5 Substances (MCL 333.7403(2)(c))

Possession of a Schedule 5 substance is a misdemeanor punishable by up to 1 year in jail and up to $2,000 fine.

Use of a Controlled Substance (MCL 333.7404)

Using or being under the influence of a controlled substance (other than marijuana, for adults 21+) is a misdemeanor punishable by up to 1 year imprisonment and up to $2,000 fine.

7411 First-Offense Deferral (MCL 333.7411)

Michigan's landmark diversion program allows first-time drug possession offenders to avoid conviction entirely. Under 7411, the court defers judgment and places the defendant on probation with conditions including drug treatment, testing, and supervision. Upon successful completion, the charge is dismissed and no public conviction record is retained. A nonpublic record is maintained by the Michigan State Police. This is a once-in-a-lifetime benefit and does not require prosecutor consent.

Michigan prohibits operating a vehicle while intoxicated or impaired under MCL 257.625. Michigan uses the terms OWI (Operating While Intoxicated) and OWVI (Operating While Visibly Impaired) rather than DUI/DWI. These laws apply to impairment by alcohol, drugs, or any combination of both.

OWI — Operating While Intoxicated (MCL 257.625(1))

A person is guilty of OWI if they operate a motor vehicle with a blood alcohol content (BAC) of 0.08% or higher, or while under the influence of a controlled substance or a combination of alcohol and drugs. There is also a “Super Drunk” or High BAC provision for BAC of 0.17% or higher, which carries enhanced penalties.

OWVI — Operating While Visibly Impaired (MCL 257.625(3))

A lesser offense where the driver’s ability to operate a vehicle is visibly impaired due to alcohol, drugs, or both.

Penalties

• First OWI offense: Misdemeanor; up to 93 days in jail, $100-$500 fine, up to 360 hours of community service, 30-day license suspension followed by 150-day restriction, 6 points on driving record.
• First High BAC (0.17%+) offense: Misdemeanor; up to 180 days in jail, $200-$700 fine, up to 360 hours of community service, 1-year license suspension (may get restricted after 45 days with ignition interlock device).
• First OWVI offense: Misdemeanor; up to 93 days in jail, up to $300 fine, up to 360 hours of community service, 90-day restricted license, 4 points on driving record.
• Second offense (within 7 years): Misdemeanor; 5 days to 1 year in jail, 30-90 days community service, $200-$1,000 fine, minimum 1-year license revocation, vehicle immobilization, 6 points.
• Third offense (felony): A third OWI/OWVI conviction (lifetime) is a felony; 1-5 years in prison or probation with 30 days to 1 year in jail, $500-$5,000 fine, license revocation for minimum 1 year (may be 5 years), vehicle forfeiture, 6 points.

Drugged Driving

Michigan is a zero-tolerance state for Schedule 1 controlled substances while driving under MCL 257.625(8). Any presence of a Schedule 1 drug (not including lawfully used marijuana for medical patients) in the driver’s body can result in an OWI charge. For marijuana, impairment must be demonstrated; there is no specific per se THC nanogram limit.

Michigan has taken significant steps to expand access to naloxone (Narcan), the opioid overdose reversal medication, as part of its response to the opioid crisis.

Pharmacy Access Without a Prescription

Under a statewide standing order issued by the Michigan Department of Health and Human Services (MDHHS), pharmacists can dispense naloxone without an individual prescription. Michigan residents can walk into a participating pharmacy and obtain naloxone directly.

Insurance Coverage

Naloxone prescriptions are covered by Michigan Medicaid and many private insurance plans. For those without insurance, free naloxone is available through various community distribution programs.

Community Distribution

MDHHS supports naloxone distribution through multiple channels:

• Syringe service programs (harm reduction organizations);
• Local health departments across all 83 Michigan counties;
• Free naloxone vending machines in select locations;
• Community-based organizations and treatment centers; and
• First responder and law enforcement programs.

Immunity for Administration

Michigan law provides civil and criminal immunity to individuals who administer naloxone in good faith to a person believed to be experiencing an opioid overdose, as well as to prescribers and dispensers who provide naloxone in accordance with the standing order.

Michigan is a national leader in the drug treatment court movement, having been one of the early adopters of the problem-solving court model.

Scope and Scale

As of 2025, Michigan operates over 80 drug treatment courts across the state, including adult drug courts, juvenile drug courts, family dependency drug courts, DUI/sobriety courts, mental health courts, and veterans treatment courts. These courts are found in at least 40 counties, including Wayne, Oakland, Macomb, Kent, Washtenaw, Ingham, Jackson, Cass, Lenawee, Ottawa, Livingston, Eaton, and Barry counties.

How Drug Treatment Courts Work

Michigan drug treatment courts use a non-adversarial, team-based approach that brings together judges, prosecutors, defense attorneys, probation officers, and substance abuse treatment providers. Participants undergo:

• Intensive supervision and frequent court appearances;
• Regular and random drug and alcohol testing;
• Mandatory participation in substance abuse treatment programs;
• Graduated phases with increasing privileges and decreasing supervision; and
• Sanctions for non-compliance and incentives for progress.

Eligibility

Eligibility varies by county, but generally requires:

• A guilty plea to the underlying offense;
• A demonstrated link between the offense and substance use;
• No prior felony assault convictions; and
• No criminal sexual conduct convictions.

Outcomes

Successful completion of drug court typically results in reduced charges, dismissed charges, or a more lenient sentence. Drug court programs generally last 12 to 18 months and address not only addiction but also housing, employment, education, and life skills.

Michigan imposes mandatory minimum sentences for certain serious drug offenses, primarily targeting large-scale drug trafficking and delivery near protected locations.

Delivery / Manufacture of Schedule 1 or 2 Narcotics (MCL 333.7401)

Mandatory minimum sentences apply to delivery or manufacture of Schedule 1 or 2 narcotic drugs based on weight:

• 1,000 grams or more: Mandatory life imprisonment.
• 450 to 999 grams: Mandatory minimum of 20 years (up to 30 years).
• 50 to 449 grams: Mandatory minimum of 10 years (up to 20 years).

Drug-Free School Zones (MCL 333.7410)

Delivery or possession with intent to deliver a Schedule 1 or 2 controlled substance within 1,000 feet of a school or library carries a mandatory 2-year minimum sentence and a maximum of up to 40 years imprisonment.

Judicial Departure

Michigan courts may depart from mandatory minimum sentences if the court finds on the record that there are substantial and compelling reasons to do so. This departure authority provides judges with some flexibility in cases where strict application of the mandatory minimum would be disproportionate to the offense.

Reform Context

Michigan reformed its mandatory minimum drug sentencing laws in 1998 and 2002, reducing some of the harshest provisions that had been in place since the 1970s and 1980s. The reforms gave judges greater discretion in sentencing and shifted the focus toward treatment for lower-level offenders while maintaining strict penalties for major drug traffickers.

Michigan offers several treatment-based alternatives to incarceration for drug offenses, reflecting a growing emphasis on rehabilitation over punishment.

7411 Deferral Program (MCL 333.7411)

Michigan's most well-known diversion program allows first-time drug possession offenders to have their case deferred and ultimately dismissed upon successful completion of probation. The court does not enter a judgment of guilt; instead, the defendant is placed on probation with conditions that may include drug treatment, counseling, community service, and regular drug testing. Successful completion results in dismissal with no public record of conviction. This is available once in a lifetime and does not require the prosecutor's consent.

769.4a Deferral (Holmes Youthful Trainee Act Alternative)

Under MCL 769.4a, defendants who plead guilty or nolo contendere may be placed on probation with a deferred judgment. Upon successful completion, the conviction is set aside. While not specific to drug offenses, this provision is frequently used in drug cases, especially for offenders who have already used their one-time 7411 benefit.

Drug Treatment Courts

Michigan's 80+ drug treatment courts provide comprehensive, court-supervised treatment programs lasting 12 to 18 months. Participants receive substance abuse treatment, mental health services, housing assistance, employment training, and intensive supervision as alternatives to incarceration.

KPEP and Residential Programs

The Kalamazoo Probation Enhancement Program (KPEP) and similar residential programs across Michigan serve as alternatives to incarceration for probationers and parolees who need more structure than standard supervision. Programming may include substance use disorder workshops, life skills classes, GED preparation, cognitive behavioral therapy, 12-Step groups, and vocational training.

Probation with Mandatory Treatment

Courts may sentence defendants to probation with conditions including mandatory participation in residential or outpatient substance abuse treatment, medication-assisted treatment (MAT) for opioid use disorder, mental health counseling, and regular drug and alcohol testing.

Michigan has seen several significant drug policy developments in recent years:

Proposal 1 — Recreational Marijuana Legalization (2018)

In November 2018, Michigan voters approved Proposal 1 with approximately 56% of the vote, legalizing recreational marijuana for adults 21+ under the Michigan Regulation and Taxation of Marihuana Act (MRTMA). The law took effect December 6, 2018, and the first licensed retail sales began on December 1, 2019. The MRTMA imposes a 10% excise tax on retail sales and allows adults to possess up to 2.5 ounces and grow up to 12 plants at home.

Local Psychedelic Decriminalization (2020-2024)

Several Michigan cities have passed measures to decriminalize entheogenic plants and fungi (including psilocybin mushrooms, ayahuasca, ibogaine, and mescaline-containing cacti):

• Ann Arbor (September 2020): First Michigan city to decriminalize, making enforcement the lowest law enforcement priority.
• Detroit (November 2021): Voters approved Proposal E to decriminalize.
• Hazel Park (November 2022): City council approved decriminalization.
• Ferndale and other cities have followed with similar measures.

State-Level Psychedelic Legislation (2023-2024)

State legislators have introduced bills to decriminalize or legalize psilocybin at the state level. In 2024, HB 5980 proposed legalizing possession of up to 2 ounces of psilocybin for adults 18+ diagnosed with PTSD. While these bills have not yet passed, they reflect growing legislative interest in psychedelic-assisted therapy.

Good Samaritan Law Enactment (2016)

Michigan enacted its Good Samaritan law (MCL 333.7404a) in 2016, providing immunity from certain drug charges for people who seek emergency medical help during an overdose. This was a key component of the state's response to the opioid epidemic.

Naloxone Standing Order Expansion

The Michigan Department of Health and Human Services expanded its statewide naloxone standing order program, enabling pharmacies to dispense naloxone without a prescription and supporting community-based distribution through health departments, harm reduction organizations, and free vending machines.
