Is THCA legal in South Dakota?
South Dakota's hemp law and its drug law use different words for the same 0.3 percent line. That one word, 'total,' is where THCA flower's status turns.
The short answer: Contested. South Dakota’s hemp chapter defines hemp by “total delta-9” THC, a phrase that can count THCA, while its drug code exempts plants with 0.3 percent “delta-9.” Regulators have not resolved how high-THCA flower fits, so we treat the hemp lane as closed. Registered medical patients can buy from licensed dispensaries. Status as of Oct. 3, 2026.

Two statutes, two phrasings
Here is the problem in the state’s own words.
| Statute | Phrase used | Source |
|---|---|---|
| SDCL 38-35-1(5), hemp | “a total delta-9 tetrahydrocannabinol concentration of not more than three-tenths of one percent on a dry weight basis” | SDCL 38-35-1 |
| SDCL 38-35-1(7), hemp products | Finished products “with a total delta-9 tetrahydrocannabinol concentration of not more than three-tenths of one percent” | same |
| SDCL 22-42-1(7), marijuana | Excludes the plant “with a delta-9 tetrahydrocannabinol concentration of not more than three-tenths of one percent” | SDCL 22-42-1 |
“Total delta-9” is the phrase federal testing rules use for delta-9 after THCA has been converted. On that reading, a high-THCA bud is not an industrial hemp product. The criminal code’s exemption omits “total,” which is the reading THCA sellers rely on. Courts have not reconciled the two as far as we could find.
There is a second wrinkle. The hemp chapter’s ban on “chemically derived cannabinoids” expressly does not cover “cannabinoids produced by decarboxylation from a naturally occurring” cannabinoid. So smoking or heating THCA, which converts it to delta-9, is not itself treated as chemical conversion.
Conflict flag: state-by-state guides split on South Dakota, from “open” to “banned.” The primary text supports “contested.” Following our rule of taking the stricter reading when sources conflict, we list the hemp lane as closed for high-THCA flower.
What is settled
Converted products are out. HB 1125, signed in March 2024, banned chemically synthesized cannabinoids such as delta-8 made from CBD, effective July 1, 2024. A federal judge, Eric Schulte, denied a preliminary injunction on June 29, 2024, writing that the Legislature acted “squarely within the police powers traditionally reserved to states” (Marijuana Moment).
The medical lane
Voters approved medical cannabis in 2020, and the Department of Health licenses dispensaries that sell flower to registered patients. Adult-use cannabis has not been enacted. Adults without a card have no licensed outlet in the state.
Dec. 11, 2026 removes the ambiguity
The two-statute argument has an expiration date. Once THCA counts under federal law on Dec. 11, 2026 (federal change), high-THCA flower is federal marijuana in South Dakota whichever state definition one prefers.
For South Dakota buyers
- Ask for a certificate of analysis that reports total THC; under the hemp chapter’s own wording, that is arguably the number that counts now, and federally it is the number from Dec. 11.
- Patients should use licensed dispensaries.

South Dakota THCA questions
Is THCA flower legal in South Dakota?
It is contested as of Oct. 3, 2026. SDCL 38-35-1 defines hemp by 'total delta-9' THC, which can be read to count THCA after decarboxylation, while the drug code's marijuana definition in SDCL 22-42-1 exempts plants with delta-9 THC of 0.3 percent or less. We take the stricter reading and treat the hemp lane as closed for high-THCA flower.
Are delta-8 and other converted cannabinoids legal in South Dakota?
No. HB 1125 (2024) banned chemically derived cannabinoids, and a federal judge declined to block it on June 29, 2024, before it took effect July 1, 2024.
Can South Dakota medical patients buy flower?
Yes. South Dakota's voter-approved medical cannabis program lets registered patients buy from licensed dispensaries. The state has no adult-use market.
