Is CBD Legal in South Dakota? South Dakota Cannabis, Hemp, and CBD Laws (2026)

Cannabidiol (CBD) is legal in South Dakota when it is made from hemp and contains no more than 0.3% delta-9 THC by dry weight. CBD made from marijuana is treated as a controlled substance and is available only to patients enrolled in the state’s medical cannabis program. That basic split — hemp-derived CBD for the general public, marijuana-derived CBD for registered patients — has held since 2020, but the rules around hemp have tightened sharply since then, and in 2026 South Dakota repealed the state program that once licensed its hemp farmers.

This guide explains what is legal to buy, sell, and carry in South Dakota today, who can buy it, and how the state’s hemp and cannabis laws fit together. South Dakota is one of the states that allow CBD only under specific conditions, so the details are worth getting right before you shop.

Is CBD legal in South Dakota?

Hemp-derived CBD is legal in South Dakota; marijuana-derived CBD is not, unless you are a medical cannabis patient. State law follows the federal line between the two plants: hemp is cannabis that contains 0.3% or less delta-9 THC by dry weight, and marijuana is everything above that threshold. CBD oils, tinctures, gummies, capsules, topicals, and pet products that are extracted from compliant hemp can be bought and sold without a license or a prescription.

Two limits matter even for legal hemp CBD. First, the cannabinoids have to be naturally derived rather than chemically converted in a lab. Second, South Dakota prohibits hemp products intended for smoking or inhaling, so hemp flower and hemp vapes are off-limits even when the CBD itself is legal. Non-inhalable formats — oils, edibles, capsules, and topicals — are where compliant CBD lives.

How South Dakota legalized hemp and CBD

South Dakota legalized hemp and hemp-derived CBD in 2020 through House Bill 1008. Then-Governor Kristi Noem signed the bill into law on March 27, 2020, after vetoing an earlier hemp measure the year before. The law legalized the cultivation, processing, and sale of industrial hemp and its derivatives, provided they stay at or below 0.3% delta-9 THC, and placed those rules in Chapter 38-35 of the South Dakota Codified Laws.

For everyday consumers, the practical effect is simple: residents can buy, sell, and carry hemp-derived CBD without any license. The growing and processing side was the regulated part. The South Dakota Department of Agriculture & Natural Resources (DANR) ran the state’s hemp program, licensing growers and processors, running background checks, and inspecting and testing crops to confirm they met the THC limit. The same 2020 law carried the ban on smoking or inhaling hemp that still applies today.

South Dakota repealed its state hemp program in 2026

In 2026, South Dakota repealed the state-run industrial hemp program and handed oversight of hemp farming back to the federal government. Governor Larry Rhoden — who became governor in January 2025 after Kristi Noem resigned to serve as U.S. Secretary of Homeland Security — signed the repeal on March 17, 2026, though the change does not take effect until January 1, 2027. The measure, Senate Bill 39, was brought by DANR itself and shifts regulatory authority over hemp production to the U.S. Department of Agriculture, mirroring moves by Nebraska and other neighboring states.

The driver was cost, not a crackdown on the crop. DANR told lawmakers the state program was not financially sustainable: fees from hemp farmers covered only about 11% of its expenses, with the rest coming from general funds. Repealing it is expected to save roughly $200,000, and because the USDA does not charge growers a license fee or regulate processors, the change removes a layer of state oversight and cost for farmers.

This is the part that confuses people, so it is worth stating plainly: the repeal changes who licenses hemp farmers, not whether you can buy CBD. Hemp-derived CBD remains legal to purchase and use, and the state’s separate restrictions on intoxicating hemp products stay in place.

Delta-8 and other lab-converted cannabinoids are banned

Delta-8 THC and similar lab-made cannabinoids are illegal in South Dakota. The state banned them through House Bill 1125, which took effect on July 1, 2024. The law prohibits the chemical modification or conversion of hemp and the sale of any product made that way, and it names the cannabinoids it targets — delta-8 THC, delta-10 THC, THC-O acetate (THC-O), HHC, and THC-P — when they are produced by chemical conversion. Violating the ban is a criminal offense.

The distinction the law draws is between naturally occurring and “chemically derived” cannabinoids. Delta-8 and delta-10 exist in hemp only in trace amounts, so marketable products are usually made by chemically converting CBD into those compounds — exactly the process House Bill 1125 outlaws. Cannabinoids that are naturally extracted are not banned. That means hemp-derived delta-9 THC products are still permitted as long as they are made from naturally extracted cannabinoids, contain no more than 0.3% delta-9 THC by dry weight, and are not designed to be smoked or inhaled.

This was a sharp turn. As recently as 2022, South Dakota had chosen to regulate delta-8 by age rather than ban it. State and local authorities began actively enforcing the 2024 ban in 2025, pulling non-compliant products from store shelves, so retailers now lean on certificates of analysis to show their inventory is naturally derived and compliant.

Marijuana-derived CBD and the medical cannabis program

CBD made from marijuana is legal in South Dakota only for registered medical cannabis patients. Voters created that pathway in November 2020 by approving Initiated Measure 26 with about 70% support, and the program is run by the South Dakota Department of Health.

Under the medical cannabis program, a patient first gets a written certification from a healthcare practitioner — a physician, physician assistant, or advanced practice registered nurse licensed in South Dakota and registered with the program — then applies to the Department of Health for a registry card. Qualifying conditions are debilitating illnesses determined by that practitioner, and they include cancer, chronic or severe pain, epilepsy and seizures, multiple sclerosis, severe nausea, severe wasting (cachexia), persistent muscle spasms, and terminal illness. Registered patients can buy and possess medical cannabis — including marijuana-derived CBD and higher-THC products — from licensed dispensaries, with possession capped at three ounces. The program tracks products from seed to sale through licensed cultivators, manufacturers, testing facilities, and dispensaries.

Adults 18 and older can hold a card in their own name; minors can qualify, but a parent or guardian must consent and act as their caregiver. By 2026 the program had grown to roughly 19,000 registered patients. This is a meaningful change from South Dakota’s older, narrower approach to medical CBD, and it sits alongside the rest of South Dakota’s cannabis laws.

Is recreational marijuana legal in South Dakota?

No. Recreational marijuana is not legal in South Dakota, which remains a medical-only state. The path there has been unusually rocky. In 2020, voters approved Constitutional Amendment A to legalize adult-use cannabis by a margin of about 54% to 46%, but the South Dakota Supreme Court struck it down for violating the state constitution’s single-subject rule for ballot measures.

Voters have since rejected legalization twice more. Initiated Measure 27 failed in 2022, and Initiated Measure 29 failed on November 5, 2024, with about 55.5% voting no. Until that changes, possessing or selling marijuana outside the medical program carries criminal penalties.

Who can buy CBD in South Dakota, and how much?

Access to CBD in South Dakota depends on whether a product is intoxicating. South Dakota law does not set a statewide minimum age for buying non-intoxicating hemp CBD, though many retailers limit sales to customers 18 or older as a matter of store policy. Intoxicating hemp products that contain THC are treated differently: the state’s enforcement position, and standard retailer practice, restrict those to adults 21 and older.

For possession, South Dakota does not impose a limit on federally compliant hemp CBD products — they are treated as ordinary consumer goods. Medical cannabis is the exception: those products are limited to registered patients, who must carry their card and stay within the program’s three-ounce possession cap.

What federal law says about CBD

Federally, hemp-derived CBD is no longer a controlled substance, but it is also not approved as a supplement or food additive. The Agriculture Improvement Act of 2018 — the 2018 Farm Bill — removed hemp containing 0.3% or less delta-9 THC from the federal Controlled Substances Act, which is what makes compliant CBD legal to sell across state lines.

The catch is that the U.S. Food and Drug Administration kept its authority over these products. The FDA has approved only one CBD-based drug, Epidiolex, a prescription medication for certain seizure disorders, and it has concluded that CBD cannot legally be sold as a dietary supplement or added to food and beverages in interstate commerce. That gap between what is widely sold and what the FDA has formally cleared is why product quality varies, and why third-party lab testing matters when you buy.

That federal baseline is set to change. In a full-year agriculture spending law enacted on November 12, 2025, Congress rewrote the federal definition of hemp, replacing the delta-9-only threshold with a total-THC test — one that also counts THCA — and capping finished hemp-derived cannabinoid products at 0.4 milligrams of total THC per container. The new definition is scheduled to take effect on November 12, 2026. If it does, it would push many hemp cannabinoid products, including some full-spectrum CBD, outside the legal hemp definition, while CBD isolate with no THC and industrial hemp would be unaffected. Lawmakers from both parties have introduced bills to delay, repeal, or replace the provision, and the change is still being contested in Washington, with the Trump administration urging Congress to protect access to non-intoxicating, full-spectrum CBD. Until that date, the 2018 Farm Bill standard described above still governs what counts as legal hemp CBD.

Where to buy CBD in South Dakota

Compliant CBD is sold across South Dakota in CBD and vape shops, wellness centers, pharmacies, and grocery stores, as well as online with delivery to the state. Because the state bans hemp products meant to be smoked or inhaled, reputable shops stock non-inhalable formats — oils, tinctures, capsules, gummies, and topicals. Whether you buy in person or online, look for a current certificate of analysis confirming the product is hemp-derived, naturally extracted rather than chemically converted, and at or below 0.3% delta-9 THC.
