Delta-8 THC is illegal in South Dakota. HB 1125, signed by Governor Kristi Noem on March 18, 2024 and effective July 1, 2024, made it a crime to chemically convert hemp into delta-8, delta-9, delta-10, or any other THC isomer, analog, or derivative. Manufacturing, distribution, or sale of chemically converted delta-8 is a Class 2 misdemeanor, with each non-compliant product treated as a separate count.
The Department of Health and Department of Public Safety launched active retail enforcement on July 14, 2025, after a June 12, 2025 courtesy notice to licensed hemp businesses. Federal H.R. 5371 §781, effective November 12, 2026, will exclude synthetic cannabinoids from the federal hemp definition nationwide.

Delta-8 THC is illegal in South Dakota. Nearly every commercial delta-8 SKU is produced through acid-catalyzed isomerization of hemp-derived CBD, which is the exact process HB 1125 bans. The bill prohibits engaging in any process that converts CBD into delta-8 THC, delta-9 THC, delta-10 THC, or any other tetrahydrocannabinol isomer, analog, or derivative. Retailers stocking delta-8 gummies, vapes, or tinctures face Class 2 misdemeanor exposure for each product on the shelf.
SDCL Chapter 38-35 governs industrial hemp. HB 1125 amended the chapter to add a prohibition on chemical modification or conversion of hemp and on the sale or distribution of chemically modified or converted hemp products. Governor Kristi Noem signed the bill on March 18, 2024. The effective date was July 1, 2024. The penalty under HB 1125 §2 is a Class 2 misdemeanor: up to 30 days in jail and a fine of up to $500 per noncompliant product manipulated or sold.
On June 12, 2025, the Department of Health and Department of Public Safety issued a joint courtesy reminder to licensed hemp retailers that active enforcement would begin July 14, 2025. Pennington County and other jurisdictions began conducting announced and unannounced sweeps in July 2025. Attorney General Marty Jackley has publicly supported the crackdown and has framed delta-8 as outside the legitimate hemp market.
HB 1125 carves out cannabinoids produced by decarboxylation from a naturally occurring cannabinoid acid without the use of a chemical catalyst. Trace amounts of naturally occurring delta-8 in compliant hemp flower or extract are not the target of the statute. The category that is banned is commercially produced delta-8 made by acid-catalyzed isomerization of CBD, which describes the vast majority of products on the market.
Medical cannabis is legal under Measure 26 (2020), administered by the Department of Health. Adult-use cannabis remains illegal: Initiated Measure 29 failed at the November 5, 2024 election (about 55% no). Attorney General Marty Jackley has confirmed that any federal rescheduling of marijuana would not change state enforcement, and only voter approval of an adult-use measure would alter the underlying framework.
Federal H.R. 5371 §781, signed November 12, 2025, excludes synthetic cannabinoids from the federal hemp definition and caps total THC in hemp-derived consumer products at 0.4 milligrams per container. The effective date is November 12, 2026. Most commercial delta-8 will lose federal Farm Bill protection on that date, which aligns federal policy with the South Dakota chemical-conversion ban already in force.
Can I buy delta-8 in South Dakota?
No. Retail sale of chemically converted delta-8 is prohibited under HB 1125 and active enforcement has been ongoing since July 14, 2025.
What is the penalty for selling delta-8?
Class 2 misdemeanor under HB 1125: up to 30 days in jail and a fine of up to $500 per noncompliant product.
Does the law cover delta-8 vapes and edibles?
Yes. The statute covers any product containing chemically modified or converted hemp cannabinoids, regardless of dose form.
Can I order delta-8 online for personal use?
HB 1125 does not separately criminalize possession by an out-of-state buyer, but shipments are subject to seizure and the controlled-substances code still applies.
What changes on November 12, 2026?
Federal H.R. 5371 §781 excludes synthetic cannabinoids from the federal hemp definition and caps total THC at 0.4 milligrams per container.
