Partially. South Dakota allows medical cannabis for registered patients with qualifying conditions, but recreational marijuana is illegal. While voters approved recreational legalization in 2020, the South Dakota Supreme Court later overturned the measure, and no replacement law has taken effect. The state also enforces some of the country’s strictest penalties for certain cannabis products. If you’re planning to use, buy, or invest in cannabis in South Dakota, it’s important to understand what state law allows and what it doesn’t.
Key Takeaways

- Hemp-derived CBD is generally legal if it contains no more than 0.3% THC and complies with state and federal law.
Historical Overview of Cannabis Regulation in South Dakota
South Dakota has prohibited cannabis since 1931, and it has remained one of the strictest states on marijuana enforcement for decades. The state briefly decriminalized cannabis in 1977, but lawmakers quickly repealed the change, restoring criminal penalties.
The biggest shift came in 2020, when voters approved two separate ballot measures. Initiated Measure 26 legalized medical cannabis with nearly 70% support, while Constitutional Amendment A legalized recreational cannabis for adults. If both measures had taken effect, South Dakota would’ve become the first state to legalize medical and adult-use cannabis in the same election.
That changed in 2021, when the South Dakota Supreme Court ruled Amendment A unconstitutional because it violated the state’s single-subject rule for constitutional amendments. As a result, recreational cannabis remained illegal. Medical cannabis, however, launched on July 1, 2021, creating a regulated program for registered patients with qualifying medical conditions.
Supporters continued to push for adult-use legalization. Voters rejected Initiated Measure 27 in 2022, followed by Measure 29 in 2024, leaving South Dakota without a recreational cannabis market.
Public opinion has become more supportive of medical cannabis than recreational use, and that distinction continues to shape state policy. At the same time, South Dakota has embraced industrial hemp. Following the 2018 federal Farm Bill, the state legalized licensed hemp cultivation and production under a regulated program, allowing farmers to grow hemp while keeping marijuana subject to separate, stricter laws.
Medical Cannabis in South Dakota: Legal Provisions and Accessibility
Medical cannabis has been legal in South Dakota since July 1, 2021, under the South Dakota Medical Cannabis Program. The program allows registered patients with qualifying medical conditions to purchase, possess, and use medical cannabis from state-licensed dispensaries.
To qualify, a patient must have a debilitating medical condition certified by a registered healthcare practitioner. Eligible conditions include cancer, chronic pain, epilepsy, multiple sclerosis, terminal illness, severe nausea, seizures, and persistent muscle spasms, among others allowed under state law.
After receiving a certification, patients must apply online through the South Dakota Department of Health. The application requires medical documentation, a completed form, and the applicable fee. Once approved, patients receive a medical cannabis card, which they must present when purchasing products from licensed dispensaries.
South Dakota tightly regulates the medical cannabis supply chain. Licensed cultivators, manufacturers, testing facilities, and dispensaries operate under state oversight, and every product moves through a mandatory seed-to-sale tracking system to ensure compliance and product safety.
Registered patients may also designate a caregiver to obtain medical cannabis on their behalf if they meet the program’s requirements. State law also permits limited home cultivation in specific circumstances, such as when a patient lives a qualifying distance from the nearest dispensary or receives authorization under program rules.
Current Legal Status of Recreational Marijuana in South Dakota
Recreational marijuana is illegal in South Dakota. Adults can’t legally buy, possess, use, or grow cannabis for non-medical purposes, and the state hasn’t decriminalized personal possession. Although voters approved recreational legalization in 2020, the South Dakota Supreme Court overturned the measure in 2021, and later ballot initiatives failed to pass.
South Dakota imposes some of the toughest cannabis penalties in the United States. Possessing 2 ounces or less of marijuana is a Class 1 misdemeanor, punishable by up to one year in jail and a fine of up to $2,000. Penalties increase with larger amounts, becoming felony offenses based on the quantity involved. State law also treats cannabis concentrates, hash, and THC edibles much more harshly than cannabis flower. Possessing these products without authorization can result in felony charges.
CBD and hemp products follow different rules. South Dakota allows hemp products that comply with federal and state hemp laws, including products derived from hemp containing less than 0.3% THC. However, the state has taken a stricter approach to intoxicating hemp-derived cannabinoids, including products containing compounds such as delta-8 THC. Laws adopted in recent years restrict the manufacture and sale of these intoxicating hemp products outside the state’s regulated medical cannabis program. Non-intoxicating hemp-derived CBD products that meet legal THC limits remain lawful.
Possession, Cultivation, and Consumption: What’s Allowed in South Dakota?
South Dakota draws a clear line between medical cannabis and recreational marijuana. Recreational users can’t legally possess, grow, or purchase cannabis. Possessing 2 ounces or less is a Class 1 misdemeanor punishable by up to one year in jail and a $2,000 fine. Larger quantities carry felony penalties that increase based on the amount involved. Cannabis concentrates, including hash and many THC extracts, are treated even more strictly and may result in felony charges.
Registered medical cannabis patients may purchase cannabis only from state-licensed dispensaries. Recreational dispensaries don’t exist because adult-use cannabis remains illegal.
Medical patients may possess cannabis within the limits established by the South Dakota Medical Cannabis Program. They may also cultivate cannabis at home only in limited circumstances, such as when they live far enough from a licensed dispensary and meet the program’s eligibility requirements. Recreational home cultivation isn’t allowed.
State law prohibits consuming cannabis in public places. Medical patients should use cannabis only in locations permitted under state law and must avoid driving while impaired. Transporting cannabis across state lines is illegal under federal law, even when traveling between states with legal cannabis programs.
Hemp-derived CBD products containing no more than 0.3% THC are legal if they comply with state and federal hemp laws. However, intoxicating hemp-derived THC products face additional restrictions and aren’t treated the same as non-intoxicating CBD products.
What Future for Cannabis Legislation in South Dakota?
South Dakota’s cannabis laws could continue to change, but recreational legalization faces significant political hurdles. Voters approved adult-use cannabis in 2020, yet the courts overturned that measure, and subsequent legalization initiatives failed in 2022 and 2024. Since then, lawmakers have focused more on adjusting the existing medical cannabis program than expanding recreational access.
Medical cannabis is expected to remain legal, although legislators periodically introduce bills that would modify how the program operates or who can participate.
For now, South Dakota continues to allow medical cannabis while prohibiting recreational use. Anyone interested in cannabis should watch future legislative sessions and ballot initiatives, as they remain the most likely paths for any major changes to state cannabis laws.
To Sum Up
Is marijuana legal in South Dakota? Partially. Medical cannabis is legal for registered patients who qualify under the state’s medical cannabis program, but recreational marijuana remains illegal. South Dakota also enforces strict penalties for unauthorized possession, cultivation, and distribution, particularly for cannabis concentrates and other high-THC products.
Cannabis laws can change through legislation, court decisions, or ballot initiatives. Before buying, possessing, or using any cannabis product in South Dakota, make sure you understand the latest rules and follow updates from the South Dakota Department of Health and state lawmakers.
