South Dakota

South Dakota made history in 2020 as the first state where voters simultaneously approved both medical cannabis and adult-use legalization on the same ballot.
Governor Kristi Noem orchestrated a legal challenge that resulted in the South Dakota Supreme Court striking down the adult-use Amendment A on single-subject rule grounds.
Subsequent adult-use ballot measures in 2022 (Initiated Measure 27) and 2024 (Initiated Measure 29) both failed, suggesting hardening opposition or ballot fatigue.
The state medical program has vastly exceeded initial enrollment projections, reaching 18,306 approved patient cards as of March 2026 against an original 2024 projection of 6,000.
The Flandreau Santee Sioux Tribe opened the state's first dispensary on tribal sovereign land on July 1, 2021, operating independently of state law and regulation.

The trajectory of cannabis policy in South Dakota represents one of the most uniquely contested legal and political battles in the modern American legalization movement. In 2020, South Dakota made unprecedented electoral history by becoming the first state in the nation where voters simultaneously approved ballot measures for both a medical cannabis program and comprehensive adult-use legalization. However, this dual mandate was swiftly fractured. While the medical program survived and subsequently launched, the adult-use measure (Amendment A) was subjected to immediate judicial challenge orchestrated by the state's executive branch. Governor Kristi Noem actively spearheaded the legal effort to strike down the adult-use amendment, resulting in the South Dakota Supreme Court invalidating the measure on the grounds that it violated the state constitution's single-subject rule. The prevailing narrative in South Dakota is defined by this clash: the voters approved adult-use cannabis, but the governor and the state's highest court dismantled it. Subsequent attempts to restore adult-use legalization through the ballot box — Initiated Measure 27 in 2022 and Initiated Measure 29 in 2024 — were defeated by the electorate, suggesting a shift in voter sentiment, organized opposition success, or ballot fatigue. Today, South Dakota operates exclusively as a medical cannabis market regulated by the Department of Health. The medical program has grown robustly, vastly exceeding initial patient enrollment projections, while parallel developments in Native American tribal sovereignty — specifically by the Flandreau Santee Sioux Tribe — have created distinct micro-economies of cannabis access within the state's geographic borders. Despite the operational medical program, criminal justice disparities persist severely for non-patients. Arrest rates for cannabis possession remain high, and racial disparities in enforcement indicate that Black and Native American populations in South Dakota are subjected to disproportionately high rates of criminalization compared to their white counterparts. Navigating South Dakota's cannabis landscape requires understanding this complex dichotomy: a functioning, state-sanctioned medical framework operating amid a deeply entrenched prohibitionist political apparatus that actively suppresses broader adult-use reforms.

Medical

Medical Program

Medical Status: Legal for qualifying patients registered with the South Dakota Medical Cannabis Program (SDMCP), administered by the Department of Health (DOH).^[14]
Medical Sales: NOT_AVAILABLE^[20]
Dispensaries: 78 dispensaries (as of late 2023)^[9]

South Dakota's medical cannabis market operates with significant data opacity — the state does not publicly report gross retail sales, product pricing, or program-level tax revenue derived from point-of-sale transactions. What is known: the program generated $2,293,915 in total administrative revenue in FY2025 ($1,358,680 from patient card fees and $935,235 from establishment fees), against expenditures of $1,426,599, rendering the administrative infrastructure self-sustaining. As of late 2023, 138 total business licenses had been issued, including 78 dispensaries, 41 cultivators, 17 manufacturers, and 2 testing labs. Patient enrollment reached 18,306 approved cards as of March 2026, far exceeding the state's original 2024 projection of 6,000. The METRC seed-to-sale tracking system is in use but its aggregated outputs are not published. A notable parallel market operates on Flandreau Santee Sioux Tribe sovereign land: Native Nations Dispensary, which opened July 1, 2021, reportedly generated up to $2 million monthly in early operations and expanded its cultivation facilities after only 10 months. This tribal economy operates entirely outside state regulation and taxation.

Despite operating a medical cannabis program, general prohibition enforcement remains highly active in South Dakota. In 2024, the state recorded 2,134 cannabis arrests — 35% of all drug-related arrests in the state, with 2,075 (97%) being simple possession charges. This represents a decline from the 2018 peak of 4,223 arrests (52% of all drug arrests), but enforcement remains substantial. Racial disparities are severe: Black and Native American residents are each approximately 5 times more likely than white residents to be arrested for cannabis possession. Pennington County (Rapid City) has been specifically flagged by researchers as having some of the most egregious racial enforcement disparities nationwide. The expungement framework is notoriously restrictive — petitions are judicial and case-by-case, automatic clearance does not exist, and since adult-use possession remains a crime, the 'no longer a crime' exemption cannot be used to clear past cannabis convictions.

What South Dakota Is Leaving on the Table

If South Dakota had adult-use cannabis sales at the level of operational states:

Benchmark	Per Capita	Rank	Estimated SD Market
Connecticut (#20)	$60.73	Lowest	$55M
New Jersey (#15)	$126.23	Mid-pack	$115M
Colorado (#9)	$196.26	Mature	$178M

Borders

Border Dynamics

Neighbor	Legal Status	Notes
North Dakota	Medical only. Adult-use legalization failed at the ballot (Measure 5) in 2024.	—
Minnesota	Adult-use legal (legalized 2023).	Minnesota permits out-of-state medical patients attending the Mayo Clinic to retain their legally acquired medical cannabis during visits.
Iowa	Highly restrictive CBD-only medical program.	—
Nebraska	Medical cannabis approved by voters in 2024; adult-use remains heavily restricted.	—
Wyoming	Strictly illegal.	—
Montana	Adult-use legal.	—

South Dakota is flanked by two adult-use states (Minnesota to the east and Montana to the northwest) and several prohibition or medical-only states. The adult-use markets in Minnesota and Montana create potential cross-border pressure, particularly on South Dakota residents near those borders who may access legal products in neighboring states and return home. No state agency publishes quantitative data on these flows or border interdiction activity. South Dakota does permit out-of-state medical patients to use its dispensaries under a reciprocity provision. The tribal market operated by the Flandreau Santee Sioux Tribe adds an additional dimension: tribal land within South Dakota offers adult-use-adjacent access that operates beyond state law.

Economic

Economic Opportunity

Fiscal Note: Because Initiated Measure 29 (2024) did not establish a commercial marketplace — proposing only private possession and home cultivation — state legislative staff did not generate a fiscal impact statement regarding new tax revenue, noting it levied no fees or commercial taxes. Any economic projections for adult-use are stalled indefinitely following the electorate's rejection. The Flandreau Santee Sioux Tribe reported early revenues of up to $2 million monthly from their tribal dispensary operation, generating economic benefits distributed to tribal members.^[33]
Neighbor Revenue: South Dakota borders two adult-use legal states (Minnesota and Montana) whose markets generate significant tax revenue — neither of which South Dakota can capture under current prohibition. Revenue and purchase flows from South Dakota residents to neighboring legal markets are unquantified.^[2]

South Dakota's economic opportunity in cannabis is substantially constrained by the failed adult-use trajectory and the opacity of the medical market's financial data. The state does not publish gross retail sales, so no market size estimate can be built from official sources. The tribal economy run by the Flandreau Santee Sioux Tribe represents a distinct and productive economic enterprise — early tribal reports cited revenues of up to $2 million monthly from the Native Nations Dispensary, with employment exceeding 50 people, the majority Native American. Future adult-use legalization scenarios that could generate state tax revenue remain effectively off the table after back-to-back ballot failures. The 2025 annual report confirms the medical program's administrative apparatus is self-sustaining but reveals no broader economic footprint.

Political

Political Trajectory

Active Bills: HB 1055 (2025 Session): 'An Act to modify medical cannabis certification requirements,' introduced by Representative Novstrup, targeting definitions and limits surrounding allowable cannabis and responsibilities of recommending medical practitioners. Earlier sessions (2023–2024) included multiple restrictive bills targeting 'pop-up clinics' issuing medical cards, introduced by Rep. Fred Deutsch.^[32]
Polling Support: 45% support, 50% opposed (October 2024, Emerson College/KELOLAND survey, ahead of Measure 29 vote).^[34]
Ballot Initiative: No active adult-use ballot initiative identified for 2026. Back-to-back failures in 2022 and 2024 have stalled momentum. Any future effort would face the same deeply hostile executive and legislative environment.^[4]

South Dakota's political landscape for cannabis is defined by the governor's successful assault on a voter-approved adult-use measure and the subsequent failure of two additional ballot initiatives. The 2020 Amendment A outcome — voters approved it, the Supreme Court struck it down at the governor's direction — is the central event in modern South Dakota cannabis politics. Initiated Measure 27 (2022) and Initiated Measure 29 (2024) both failed, with the 2024 result of 55.54% opposed representing the worst performance for legalization advocates across the three-attempt cycle. The opposition is institutionally entrenched at the highest levels of state government. Legislative activity in the medical program leans restrictive — 2023–2024 sessions saw bills targeting medical card issuance practices. South Dakota is firmly classified as Medical Only with no credible near-term path to adult-use legalization.
