South Dakota Drug Laws: Penalties, Charges & Treatment Options

South Dakota's drug laws are primarily governed by two statutory chapters: SDCL Title 22, Chapter 42 (Controlled Substances and Marijuana), which establishes criminal offenses and penalties, and SDCL Title 34, Chapter 20B (Drugs and Substances Control), which defines controlled substance schedules and regulatory frameworks. The state uses a four-schedule classification system (Schedules I through IV), unlike the federal five-schedule system. South Dakota is notable for having some of the most stringent drug laws in the nation. It is the only state with a standalone felony ingestion statute (SDCL § 22-42-5.1), which criminalizes merely having a controlled substance in one's body without a valid prescription. A 2023 legislative effort to soften this provision (SB 201) narrowly failed on an 18-17 vote in the Senate. The state's marijuana laws have been shaped by a tumultuous political and legal history. In November 2020, voters passed both Amendment A (recreational marijuana legalization, 54% approval) and Initiated Measure 26 (medical marijuana, 70% approval). Governor Kristi Noem challenged Amendment A in court, and the South Dakota Supreme Court struck it down in November 2021 in a 4-1 ruling (Thom v. Barnett), finding it violated the state constitution's single-subject requirement. A subsequent ballot measure, Initiated Measure 27, was defeated by voters in November 2022 with 52.8% opposing. Medical marijuana under Measure 26 survived and became operational on July 1, 2021, codified as SDCL Chapter 34-20G. In recent years, South Dakota has focused on enhanced penalties for fentanyl-related offenses, adding specific mandatory minimums tied to fentanyl quantities under SDCL § 22-42-2. The state also maintains a 24/7 sobriety program and operates drug court and DUI court programs as alternatives to incarceration for qualifying offenders.

South Dakota imposes penalties for drug possession under SDCL § 22-42-5 and has a unique felony ingestion statute under SDCL § 22-42-5.1. South Dakota is the only state in the nation that criminalizes the mere ingestion of a controlled substance as a standalone felony offense. Schedule I or II Possession (SDCL § 22-42-5): Unauthorized possession of a Schedule I or II controlled substance (cocaine, heroin, methamphetamine, fentanyl, etc.) is a Class 5 felony, punishable by up to 5 years in the state penitentiary and a $10,000 fine. Schedule III or IV Possession (SDCL § 22-42-5): Unauthorized possession of a Schedule III or IV controlled substance is a Class 6 felony, punishable by up to 2 years in the state penitentiary and a $4,000 fine. Felony Ingestion (SDCL § 22-42-5.1): It is a felony to knowingly ingest a controlled substance or have a controlled substance present in one's body without a valid prescription. This statute has been widely criticized by criminal justice reform advocates. A violation involving a Schedule I or II substance is a Class 5 felony; a violation involving a Schedule III or IV substance is a Class 6 felony. In 2023, Senate Bill 201 attempted to reduce the ingestion penalty so that prison time would only apply on a third offense, but it failed on an 18-17 Senate vote. Marijuana Possession (SDCL § 22-42-6): Marijuana possession penalties are tiered by amount:

• 2 ounces or less: Class 1 misdemeanor — up to 1 year in county jail and a $2,000 fine.
• More than 2 oz but less than 8 oz: Class 6 felony — up to 2 years and $4,000 fine.
• 8 oz or more but less than 1 lb: Class 5 felony — up to 5 years and $10,000 fine.
• 1 lb to 10 lbs: Class 4 felony — up to 10 years and $20,000 fine.
• More than 10 lbs: Class 3 felony — up to 15 years and $30,000 fine.

Drug-Free Zone Enhancements (SDCL § 22-42-19): Distribution or possession with intent to distribute within 1,000 feet of a school, playground, or within 500 feet of a youth center, public swimming pool, or video arcade is a Class 4 felony with a mandatory minimum of 5 years consecutive imprisonment. The sentence may not be suspended, and it is not a defense that the defendant did not know the distance involved or that school was not in session.

South Dakota prosecutes impaired driving under SDCL Chapter 32-23. The legal BAC limit is 0.08% for adults and 0.02% for persons under age 21. South Dakota's DUI law covers impairment from alcohol, marijuana, non-prescribed drugs, and intoxicating inhalants. First Offense DUI (SDCL § 32-23-2): Class 1 misdemeanor. Up to 1 year in jail and a fine of up to $2,000. Driver's license revocation for 30 days. Substance abuse evaluation may be required. Second Offense DUI (SDCL § 32-23-4): Class 1 misdemeanor. Up to 1 year in jail and a fine of up to $2,000. Driver's license revocation for 180 days. The court may order ignition interlock device installation and mandatory substance abuse treatment. Third or Subsequent Offense DUI (SDCL § 32-23-4.6): If a person is convicted of DUI three or more times within a 10-year period, it is a Class 6 felony, punishable by up to 2 years in the state penitentiary and a $4,000 fine. Driver's license revocation for 1 year. High BAC Enhancement: A DUI involving a BAC of 0.17% or greater triggers mandatory alcohol and drug evaluation and may require completion of a chemical dependency program. Under-21 Zero Tolerance: Drivers under age 21 may not operate a motor vehicle after consuming marijuana or any controlled substance for as long as physical evidence of consumption remains in the body, or with a BAC of 0.02% or higher. Implied Consent (SDCL § 32-23-10): South Dakota's implied consent law requires drivers to submit to chemical testing when lawfully requested. Refusal results in automatic license revocation. 24/7 Sobriety Program: South Dakota pioneered the 24/7 Sobriety Program, which requires DUI offenders to submit to twice-daily alcohol breath testing (or continuous alcohol monitoring) as a condition of bond or probation. The program has been nationally recognized and replicated by multiple other states.

South Dakota has enacted naloxone access provisions under SDCL §§ 34-20A-104 through 34-20A-108 to expand availability of the opioid overdose reversal medication. Prescriber Authority (SDCL § 34-20A-104): A licensed healthcare professional may, directly or by standing order, prescribe an opioid antagonist (naloxone) to a person at risk of experiencing an opioid-related overdose, or to a family member, friend, or other person reasonably believed to be in a position to assist someone at risk of overdose. Statewide Standing Order: South Dakota has a statewide standing order for naloxone issued by the Department of Health, allowing pharmacists to dispense naloxone without a patient-specific prescription. All pharmacists who dispense naloxone under the standing order must complete at least 1 hour of training related to naloxone dispensing and administration. Pharmacy Requirements: Pharmacies dispensing naloxone must complete a short eligibility assessment form for every individual who receives the medication. Good Faith Administration: Individuals who administer naloxone in good faith to a person experiencing a suspected opioid overdose are protected from civil liability. Distribution Programs: The South Dakota Department of Health and community organizations distribute naloxone through harm reduction programs. The state's 'Let's Be Clear SD' initiative works to increase naloxone availability at pharmacies statewide. Over-the-Counter Availability: Following the FDA's 2023 approval of over-the-counter naloxone (Narcan nasal spray), naloxone is also available without a prescription at pharmacies throughout South Dakota.

South Dakota operates treatment courts under the supervision of the South Dakota Unified Judicial System (UJS). These include Drug Courts, DUI Courts, Veterans Courts, and Mental Health Courts. Program Overview: South Dakota currently has ten drug courts, including two with a DUI track. Treatment courts are the state's primary intervention for individuals with substance use and mental health disorders transitioning from the criminal justice system into recovery. Program Structure: Drug court programs typically last 18 to 24 months and include multiple phases. Requirements generally include maintaining sobriety, attending group therapy, maintaining employment, and completing parenting classes where applicable. Treatment providers develop personalized, evidence-based plans for each participant, while probation officers provide community supervision. Eligibility: Drug courts handle persons with substance abuse problems who have been charged with drug-related offenses. Felony DUI offenders may also qualify for drug court placement. Violent offenders are generally excluded. Outcomes: Participants who complete the 18- to 24-month program without violations — meeting sobriety, therapy, employment, and other requirements — can avoid prison. Successful completion may result in reduced charges or dismissal. DUI Courts: South Dakota DUI courts are specialized courts convened for persons charged with driving under the influence. A 2024 legislative change creating mandatory minimum sentences for repeat DUI offenders was expected to increase referrals to DUI courts as judges and prosecutors seek treatment-based alternatives. Funding: Treatment courts receive funding through state appropriations, federal grants, and participant contributions.

South Dakota imposes mandatory minimum sentences for several categories of drug offenses, primarily under SDCL § 22-42-2 and related statutes. Manufacturing or Distribution — Schedule I or II Substances (SDCL § 22-42-2):

• Basic offense: Class 4 felony (up to 10 years). A first conviction carries a mandatory minimum sentence of at least 1 year in a state correctional facility, which may not be suspended.

Fentanyl-Specific Mandatory Minimums (SDCL § 22-42-2):

• 4 mg to less than 14 mg of fentanyl: Class 2 felony (up to 25 years). Mandatory minimum of 3 years in a state correctional facility.
• 14 mg or more of fentanyl: Class 2 felony (up to 25 years). Mandatory minimum of 10 years in a state correctional facility.

Distribution to Minors (SDCL § 22-42-2):

• First offense: Class 2 felony. Mandatory minimum of 1 year in a state correctional facility, non-suspendable.
• Second or subsequent offense: Mandatory minimum of 15 years in a state correctional facility, non-suspendable.

Drug-Free Zone Violations (SDCL § 22-42-19):

• Mandatory minimum of 5 years imprisonment in a state correctional facility. The sentence must be consecutive to any sentence for the underlying felony and may not be suspended. The court may depart from the mandatory sentence only upon finding mitigating circumstances.

Habitual Offender Enhancement: South Dakota's habitual offender statutes may further increase mandatory minimums for individuals with prior felony drug convictions. Impact: South Dakota's mandatory minimums for drug offenses are among the most severe in the region, particularly regarding fentanyl. The combination of felony ingestion laws, mandatory minimums for distribution, and drug-free zone enhancements creates a strict sentencing framework that has drawn attention from criminal justice reform advocates.

South Dakota offers several treatment-based alternatives to incarceration for individuals charged with drug offenses: Drug Court Programs: South Dakota's ten drug courts provide supervised treatment programs lasting 18 to 24 months for qualifying substance abuse offenders. Participants must maintain sobriety, attend therapy, hold employment, and comply with all program requirements. Successful completion can result in avoiding prison time. Pretrial Diversion Programs: A state's attorney may agree to suspend prosecution of drug possession charges and place the defendant in a diversion program. Under a diversion contract, the prosecutor agrees not to pursue charges so long as the defendant remains law-abiding, participates in treatment or counseling, and complies with all terms. Successful completion results in case dismissal. Suspended Imposition of Sentence: South Dakota courts may suspend the imposition of sentence for certain drug offenses, placing the defendant on probation with conditions that may include substance abuse treatment, drug testing, and community service. 24/7 Sobriety Program: South Dakota's nationally recognized 24/7 Sobriety Program can be used as a condition of a suspended sentence or probation in drug and DUI cases. Participants must submit to twice-daily breath testing or wear continuous alcohol monitoring devices. The program emphasizes accountability and has been shown to reduce recidivism. Substance Abuse Evaluation and Treatment: Courts may order substance abuse evaluations and mandate completion of treatment programs — including outpatient counseling, intensive outpatient programs, or residential treatment — as a condition of probation or a suspended sentence. DUI Court Programs: Specialized DUI courts provide treatment-focused alternatives for repeat DUI offenders, incorporating elements similar to drug court programs with additional focus on impaired driving behavior. Tribal Court Programs: Several South Dakota tribal nations, including the Oglala Sioux Tribe and Rosebud Sioux Tribe, operate their own tribal healing-to-wellness courts that address substance abuse through culturally informed treatment approaches.

2020 — Amendment A and Initiated Measure 26: In November 2020, South Dakota voters approved both Amendment A (recreational marijuana legalization, 54% in favor) and Initiated Measure 26 (medical marijuana, 70% in favor). Amendment A would have legalized recreational marijuana for adults 21 and older, along with provisions for medical marijuana and hemp. Measure 26 established a standalone medical cannabis program. 2021 — Amendment A Struck Down: Governor Kristi Noem backed a legal challenge to Amendment A, with Highway Patrol Superintendent Col. Rick Miller filing suit. On February 8, 2021, Circuit Court Judge Christina Klinger ruled Amendment A unconstitutional for violating the single-subject rule. On November 24, 2021, the South Dakota Supreme Court upheld the ruling in a 4-1 decision (Thom v. Barnett), with Chief Justice Steven Jensen writing that the amendment contained 'provisions embracing at least three separate subjects.' Medical marijuana under Measure 26 became operational on July 1, 2021. 2022 — Initiated Measure 27 Defeated: A follow-up statutory initiative, Initiated Measure 27, sought to legalize possession of up to one ounce of recreational marijuana for adults 21 and older. Unlike Amendment A, it did not address licensing, taxation, or hemp. Voters rejected IM-27 on November 8, 2022, with 52.8% voting against. 2023 — Ingestion Statute Reform Fails: Senate Bill 201, which would have reduced penalties under the felony ingestion statute (SDCL § 22-42-5.1) so that prison time would apply only on a third offense, failed on an 18-17 vote in the South Dakota Senate. 2023-2024 — Enhanced Fentanyl Penalties: The legislature strengthened penalties for fentanyl-related offenses under SDCL § 22-42-2, establishing specific mandatory minimums of 3 years (4-14 mg) and 10 years (14+ mg) for distribution involving fentanyl. These provisions reflect the state's response to the national fentanyl crisis. 2024 — DUI Mandatory Minimums: Legislative changes creating mandatory minimum sentences for repeat DUI offenders prompted increased preparation among DUI courts statewide, as judges and prosecutors anticipated more referrals to treatment-based alternatives. Medical Cannabis Program Expansion: Since its launch in 2021, the medical cannabis program has continued to grow, with additional dispensaries receiving licenses and the patient registry expanding. Administrative rules under ARSD 44:90 continue to be refined.
