Current Hemp Law Status in South Dakota
South Dakota repealed its state industrial hemp program in March 2026 through Senate Bill 39, shifting hemp-cultivation regulation to the USDA rather than a state licensing program. The state agency is the Department of Agriculture and Natural Resources, or DANR; “South Dakota Department of Agriculture” and “SDDA” are stale names from before the 2021 agency merger. See South Dakota Public Broadcasting's report on the repeal and the DANR industrial hemp page.
South Dakota has not legalized adult-use cannabis. Voter-approved Amendment A was struck down by the South Dakota Supreme Court in 2021, and later legalization measures failed in 2022 and 2024. See the Marijuana Policy Project's South Dakota overview.
The state does have an active medical cannabis program through the Department of Health. It has operated since July 1, 2021, and had more than 18,000 registered patients as of April 2026. See the South Dakota Department of Health Medical Cannabis Program.
What's Changing in 2026
The major state-program change already occurred: South Dakota repealed its industrial hemp program in March 2026 and moved cultivation oversight to the USDA. The state's chemically modified hemp-cannabinoid ban is older. House Bill 1125 took effect on July 1, 2024 and prohibits chemically converting industrial hemp and selling or distributing chemically modified hemp products, including Delta-8, Delta-10, THC-O, HHC, and THC-P. Active enforcement began July 14, 2025.
Delta-8 Status
Delta-8 sale and distribution is already illegal in South Dakota under House Bill 1125. It is not lawfully “widely available,” and the November 2026 federal change is not the event that first makes Delta-8 sales illegal in the state. See the South Dakota Legislature's HB 1125 record.
CBD Rules
Federally compliant hemp-derived CBD is legal in South Dakota. Since the March 2026 repeal of the state industrial hemp program, growers register directly with the USDA rather than with a state hemp-grower registry. See the DANR industrial hemp page.
South Dakota's medical cannabis program is a separate state program administered by the Department of Health. It has operated since July 1, 2021. See the program page.
Vape and E-cig Status
Hemp-derived CBD vapes remain legal in South Dakota, but Delta-8 vaping products are illegal under House Bill 1125 because the statute bans chemically modified hemp cannabinoids regardless of delivery method. The law has been actively enforced since July 2025. See the HB 1125 record.
How the Scheduled Federal November 2026 Changes May Affect South Dakota Residents
Section 781 of the Continuing Appropriations and Extensions Act, 2026 (H.R. 5371), enacted as Public Law 119-37 on 2025-11-12, sets 2026-11-12 as the effective date for the federal hemp provisions. On that date, the federal standard applies a 0.3% total-THC test inclusive of THCA and delta-8, caps finished hemp products at 0.4 mg total THC per container, and excludes cannabinoids that are not naturally produced by the plant as well as naturally occurring cannabinoids synthesized outside the plant. On 2026-08-08, the Senate passed H.R. 6500 containing proposed one-month partial-delay language. That language was not enacted as part of P.L. 119-37. See Congress.gov's H.R. 5371 / Public Law 119-37 record.
The November 2026 federal change is a separate, additional restriction. Delta-8 sales are already illegal in South Dakota under House Bill 1125.
