Cannabis in South Dakota: Laws, Legal Status, Recreational & Medical Use

South Dakota maintains a unique and often complex relationship with cannabis, characterized by a robust, voter-approved medical program and a repeated rejection of recreational legalization. While voters initially approved both medical and recreational cannabis in 2020, the recreational measure (Amendment A) was subsequently overturned by the State Supreme Court. Most recently, in November 2024, voters defeated Initiated Measure 29, which would have legalized adult-use cannabis for those 21 and older. Today, the South Dakota Department of Health (DOH) oversees a strictly regulated medical market, while the state legislature continues to debate the boundaries of hemp-derived cannabinoids and patient protections in early 2026.

Cannabis Legal Status in South Dakota

South Dakota allows medical cannabis use for registered patients with a valid state-issued card. However, recreational use remains a criminal offense. Notably, South Dakota is the only state in the U.S. with a “possession by ingestion” law, meaning that testing positive for cannabis can be prosecuted as a criminal offense even if no physical product is found on the individual.

Recreational Cannabis Laws in South Dakota

Legal Age Requirements

There is no legal age for recreational cannabis as it remains prohibited. For the medical program, patients must be 18 or older, while minors require a parent or legal guardian to serve as a designated caregiver.

Possession Limits

• 2 ounces (56 g) or less: Class 1 misdemeanor (Up to 1 year in jail and a fine of up to $2,000).
• 2 ounces to 0.5 pounds: Class 6 felony (Up to 2 years in prison and a fine of up to $4,000).
• Ingestion: Having THC metabolites in your system is considered “unauthorized ingestion,” a Class 1 misdemeanor.

Where Cannabis Can Be Purchased

Recreational cannabis cannot be legally purchased in South Dakota. Any retail sale outside of a licensed medical dispensary is a criminal offense.

Public Consumption Laws

Public consumption is strictly prohibited. Use is restricted to private property. Even for medical patients, consumption is limited to private residences or private locations where the owner has permitted it.

Home Cultivation

Home cultivation is illegal for recreational use. However, registered medical patients may be authorized to grow up to two mature plants and two immature plants at their residence, provided they are kept in a secure, locked facility out of public view.

Medical Cannabis in South Dakota

Medical Cannabis Program

The South Dakota Medical Cannabis Program was established by Initiated Measure 26. As of March 2026, the program serves over 18,000 patients and allows access to a variety of lab-tested products through state-licensed dispensaries.

Qualifying Conditions

Qualifying debilitating medical conditions include cancer, glaucoma, HIV/AIDS, ALS, multiple sclerosis, Crohn’s disease, PTSD, and any chronic condition producing severe pain, severe nausea, seizures, or persistent muscle spasms.

Patient Registration

Patients must obtain a written certification from a licensed physician, physician assistant, or nurse practitioner with whom they have a bona fide relationship. The application fee for a patient card is $100.

Medical vs Recreational Differences

• Purchase Limits: Patients may purchase up to 3 ounces of cannabis flower every 14 days.
• Legal Protection: Registered cardholders are protected from arrest and prosecution for possessing allowable amounts.
• Access to Potency: Medical patients have access to concentrated extracts and edibles that are otherwise restricted for general possession.

Summary of Cannabis Laws in South Dakota

South Dakota remains a state of contrasts in the cannabis landscape. While it offers a successful medical program for patients with debilitating conditions, it also maintains some of the nation’s harshest “ingestion” and “zero-tolerance” driving laws. Patients benefit from a robust selection of lab-tested products and the right to limited home cultivation, but the general public faces significant criminal risks for even minor possession. As the state legislature continues to professionalize the medical market and crack down on unregulated hemp products, South Dakota remains a key example of a state prioritizing clinical access over broad adult-use legalization.
