Minnesota Drug Laws: Penalties, Charges & Treatment Options

Under Minnesota law, drug possession offenses are classified across five degrees (Minn. Stat. §§ 152.021–152.025). The severity depends on the type of substance, quantity, and the defendant's criminal history. First-degree possession of 25 grams or more of cocaine, heroin, or methamphetamine carries up to 30 years and $1,000,000 in fines. Second-degree possession (6+ grams) carries up to 25 years and $500,000. Third-degree possession (3+ grams of narcotics) carries up to 20 years and $250,000. Fourth-degree possession of small amounts is generally a felony with up to 5 years and $10,000, though first-time offenders possessing less than 0.25 grams face a gross misdemeanor. Fifth-degree possession (simple possession of any controlled substance) can be a felony or gross misdemeanor depending on amount and prior history. Recent reforms have reduced penalties for small-amount, first-time possession and eliminated mandatory minimums for third- through fifth-degree offenses.

Driving While Impaired (DWI) — Minn. Stat. Chapter 169A

Minnesota prosecutes drug-impaired driving under Chapter 169A of the Minnesota Statutes. It is illegal to drive, operate, or be in physical control of a motor vehicle while under the influence of a controlled substance, a hazardous substance, or any combination of alcohol and drugs. Under Minn. Stat. § 169A.20, it is also illegal to drive while having any amount of a Schedule I or Schedule II controlled substance (other than marijuana, following legalization) in the body. Minnesota classifies DWI offenses into four degrees based on aggravating factors such as prior offenses, BAC of 0.16 or higher, or a child under 16 in the vehicle.

• Fourth-degree DWI (first offense, no aggravating factors) — Notes: May qualify for diversion or reduced penalties
  Classification: Misdemeanor
• Third-degree DWI (one aggravating factor) — Notes: Aggravating factors include BAC of 0.16+, prior DWI within 10 years, child under 16 in vehicle
  Classification: Gross Misdemeanor
• Second-degree DWI (two or more aggravating factors) — Notes: Ignition interlock may be required
  Classification: Gross Misdemeanor
• First-degree DWI (4+ offenses in 10 years or prior felony DWI) — Notes: Mandatory minimum sentence under sentencing guidelines
  Classification: Felony
• Criminal vehicular homicide or injury (DWI-related) — Notes: Under Minn. Stat. § 609.21
  Classification: Felony

Minnesota has an implied consent law (Minn. Stat. § 169A.51). Refusal to submit to chemical testing results in automatic license revocation for a minimum of 1 year. Refusal with aggravating factors can result in criminal charges.

Following marijuana legalization, driving under the influence of cannabis remains illegal. Officers use field sobriety tests and drug recognition expert evaluations. Minnesota does not currently have a per se THC impairment threshold.

Minnesota has comprehensive naloxone access provisions under Minn. Stat. § 604A.04 (Good Samaritan Overdose Prevention). Any licensed health care professional may directly or by standing order prescribe, dispense, distribute, or administer naloxone (an opioid antagonist) without being subject to civil liability or criminal prosecution. Non-healthcare professionals may possess and administer naloxone prescribed or dispensed by a licensed professional. Anyone who administers naloxone in good faith to a person believed to be suffering an overdose is immune from criminal prosecution and civil liability. Minnesota maintains a statewide naloxone standing order through the Minnesota Department of Health, allowing pharmacies to dispense naloxone without an individual prescription. The 2023 legislature mandated that first responders carry naloxone.

Minnesota operates an extensive network of treatment courts as alternatives to traditional criminal proceedings for substance-involved offenders. The state has approximately 26 adult drug courts, 14 DWI courts, and 8 hybrid courts combining different treatment court models. Treatment courts provide court-supervised substance abuse treatment, regular drug testing, judicial monitoring, and graduated sanctions and incentives. Participants work with judges, prosecutors, public defenders, probation officers, and social workers to develop individualized recovery plans. The Minnesota Judicial Branch oversees these programs, with the Department of Human Services providing additional treatment court support and funding.

Available statewide across multiple judicial districts; approximately 48 treatment courts total including adult drug courts, DWI courts, juvenile drug courts, family dependency courts, mental health courts, and veterans courts.

• Adult Drug Courts (26)
• DWI Courts (14)
• Hybrid Courts (8)
• Family Dependency Treatment Courts
• Juvenile Drug Courts
• Mental Health Courts
• Veterans Treatment Courts

Generally limited to nonviolent drug offenders; specific eligibility criteria determined by each judicial district. Participants typically face 12-24 months of court-supervised treatment.

Minnesota has significantly reformed its mandatory minimum sentencing for drug offenses in recent years. Mandatory minimums now apply primarily to first- and second-degree controlled substance crimes with aggravating factors. For a conviction of a first- or second-degree controlled substance crime within ten years after completing a sentence for a previous first- or second-degree drug felony, the court must impose a mandatory minimum of 48 months (first-degree) or 36 months (second-degree). An aggravated first-degree offense involving 100+ grams or 500+ dosage units with a firearm or two or more aggravating factors carries a mandatory minimum of 86 months (approximately 7 years). Importantly, recent reforms have eliminated mandatory minimums for third-, fourth-, and fifth-degree drug offenses.

Aggravated First Degree: 86 months mandatory minimum (100+ grams with firearm or 2+ aggravating factors)

First Degree Repeat: 48 months mandatory minimum (prior 1st/2nd degree conviction within 10 years)

Second Degree Repeat: 36 months mandatory minimum (prior 1st/2nd degree conviction within 10 years)

Mandatory minimums eliminated for 3rd, 4th, and 5th degree drug offenses. Weight thresholds raised from 10g to 17g for first-degree cocaine/meth crimes and from 3g to 10g for second-degree.

Minnesota provides multiple treatment alternatives to incarceration for drug offenders. The state's treatment court network is one of the most extensive in the nation, and diversion programs are available in many counties. Pretrial and pre-charge diversion programs allow first-time or low-level offenders to avoid a criminal record by completing treatment requirements over 12-24 months. Minnesota's sentencing guidelines also allow for downward departures from presumptive sentences when treatment is warranted, and the state's Stay of Adjudication provisions enable courts to defer judgment pending completion of treatment conditions.

• Treatment Courts (Drug Courts, DWI Courts)
  Description: Court-supervised treatment programs with graduated sanctions and incentives, regular drug testing, judicial monitoring, and collaborative case management. Approximately 48 treatment courts operate statewide.
• Pretrial Diversion Programs
  Description: County-level diversion programs that allow first-time or low-level drug offenders to complete treatment, community service, and supervision requirements in exchange for case dismissal. Available in many Minnesota counties.
• Stay of Adjudication
  Description: Courts may stay adjudication of a guilty plea, allowing the defendant to complete probation and treatment. Upon successful completion, charges may be dismissed and the record may be eligible for expungement.
• Certified Chemical Dependency Treatment
  Description: Court-ordered chemical dependency treatment through the Minnesota Department of Human Services, including inpatient, outpatient, and extended care programs covered by state funding for eligible individuals.
