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

South Dakota permits medical cannabis through its Department of Health program, while recreational possession and sales remain prohibited. Patients must follow registration, product and location rules. Hemp has a separate legal framework, including restrictions on chemically converted cannabinoids and a coming change to state production oversight.

Cannabis Legal Status in South Dakota

Medical authorization is conditional: it does not permit impaired driving or unlimited possession. Unauthorized ingestion is a separate legal issue from possessing a physical product.

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

SDCL 22-42-6 classifies unauthorized possession of two ounces or less as a Class 1 misdemeanor. More than two ounces but less than half a pound is a Class 6 felony; exactly half a pound enters the Class 5 felony category. Larger quantities carry higher classifications. These criminal thresholds are separate from the medical allowance.

Unauthorized ingestion for intoxication can be prosecuted under SDCL 22-42-15. Its terms include intent and exceptions; a positive test should not be described as automatically proving every element of an offense.

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

SDCL 34-20G-18 prohibits medical smoking or vaping on public transportation, in public places or places open to the public, and by anyone under 21. Medical authorization also does not override property restrictions. A patient card is not permission to consume anywhere or to drive under the influence.

Home Cultivation

Recreational home growing is prohibited. Medical patients must specifically obtain cultivation authorization; a patient card alone is insufficient. The home-cultivation endorsement permits no more than two flowering and two nonflowering plants. Follow secure-location requirements and any landlord restrictions.

Medical Cannabis in South Dakota

Medical Cannabis Program

The South Dakota Medical Cannabis Program administers patient registration and establishment certification. Its current dashboard provides dated patient counts; those counts should not be treated as a fixed measure of eligibility or dispensary availability.

Qualifying Conditions

Eligibility is defined by SDCL 34-20G-1. The list includes HIV/AIDS, ALS, multiple sclerosis, Crohn’s disease, epilepsy or seizures, PTSD, and cancer with specified associated symptoms. Chronic or debilitating conditions producing severe debilitating pain, wasting, severe nausea (excluding pregnancy-related nausea), seizures or severe persistent muscle spasms can also qualify. Certification requires a bona fide practitioner-patient relationship.

Patient Registration

The Department of Health lists a $75 standard card fee, a $20 qualifying low-income card, and an additional $20 for cultivation authorization. Authorized certifiers include physicians, physician assistants and advanced practice registered nurses with the required prescribing authority. Certification begins the application process; it is not itself a completed card application.

Medical vs Recreational Differences

The purchase allowance is three ounces in a rolling 14-day period, tracked when medicine is dispensed. Product-equivalent weights count toward the allowance; changing product type does not reset it.

The ordinary possession allowance is three ounces, with product equivalents established by rule. Authorized cultivators have a separate allowance for products from their permitted plants kept at the cultivation property. None of these quantities is a recommended medical dose.

Is CBD Legal in South Dakota?

Hemp-derived CBD may qualify under state hemp law, but the exact product and manufacturing process matter. The 0.3% threshold does not authorize every item labeled hemp.

Hemp-Derived CBD

SDCL 34-20B-118 already prohibits specified chemical conversion of hemp or CBD and selling or distributing hemp products containing chemically derived cannabinoids. This restriction dates to 2024; it was not waiting for SB 61 to become law. The state hemp definition uses total delta-9 THC, accounting for potential THC from THCA, rather than only the measured delta-9 THC before conversion.

Cannabis-Derived CBD

CBD products derived from cannabis or containing more than 0.3% THC are restricted to licensed medical dispensaries.

CBD Food and Beverage Laws

Do not equate a hemp-compliant concentration with food approval. The FDA states that CBD cannot lawfully be added to foods or dietary supplements. Retail availability and a laboratory report do not override that rule.

Buying CBD in South Dakota

Check the exact product, cannabinoid composition and manufacturing method before ordering, including whether it contains prohibited chemically converted cannabinoids. Products offered elsewhere may not qualify for sale or shipment to South Dakota. A brand listing does not establish legal approval for its full catalog.

Where to Buy Cannabis in South Dakota

Licensed Cannabis Dispensaries

Only registered medical patients can purchase from licensed dispensaries. Available products include:

• Cannabis flower and pre-rolls
• Concentrates, resins, and vapes
• Edibles and lozenges
• Topicals and tinctures

Online Ordering and Pickup

Check current menus and pickup arrangements directly with a permitted dispensary. Patients and caregivers must follow program identification and dispensing requirements. An online order is not authorization for unrestricted delivery or for purchasing outside the regulated medical system.

Cannabis Taxes

Medical cannabis purchases are subject to sales tax. The current state rate is 4.2%, with general municipal tax of up to 2% where applicable. The Department of Revenue’s medical cannabis guidance confirms municipal tax can apply; its older state-rate figure has since changed.

Cannabis Penalties and Restrictions

South Dakota’s DUI law prohibits driving under the influence of marijuana. Medical-program protection does not excuse impaired driving.

Unauthorized possession, ingestion, distribution and paraphernalia involve different statutory offenses and exceptions. The criminal cannabis statutes also separately restrict smoking or consuming marijuana in an operating vehicle. A medical card does not eliminate all criminal exposure.

Future Cannabis Legislation in South Dakota

SB 61 did not pass in 2026: the January 22 motion to place it on the Senate calendar failed, 14–19. Its proposed broader hemp-intoxicant ban should not be presented as current law.

SB 39 was signed in March 2026. It ends the state industrial-hemp production program effective January 1, 2027, with the revised law recognizing USDA and tribal producer licensing. This is a production-oversight change, not recreational marijuana legalization or blanket approval of retail CBD products.
