What South Carolina law says about THCA

South Carolina’s Hemp Farming Act defines hemp as cannabis with “the federally defined THC level for hemp”, and the state’s hemp testing uses post-decarboxylation or similarly reliable methods². The Attorney General’s 16 September 2024 opinion recalls a 2019 opinion finding that material with more than 0.3% delta-9 THC measured by those methods would likely be deemed marijuana¹. Because THCA converts to delta-9 THC when heated, most THCA flower, pre-rolls and concentrates fail that test.

The 2024 opinion confirmed that hemp products with 0.3% delta-9 THC or less on a dry weight basis are legal, but stressed that legality must be decided product by product through laboratory testing¹. In Operation Ganjapreneur the State Grand Jury charged distributors with marijuana trafficking and possession with intent to distribute, and the Attorney General said 261 of 270 brands tested so far “came back hot”³⁴.

South Carolina has no adult-use or comprehensive medical cannabis programme, so there is no licensed channel for THCA flower. H 3924, a bill to regulate hemp-derived consumables, failed in June 2026⁵. The federal total-THC definition from 11 December 2026 will reinforce the state’s position.

Pending changes to watch

No hemp regulation bill was enacted in the 2025-2026 session.

How the federal hemp change affects South Carolina

Separate from South Carolina law, the federal definition of hemp is changing. Under the federal hemp redefinition passed in the FY2026 appropriations law, from 11 December 2026 hemp is measured by total THC, which counts THCA as well as delta-9 THC, and finished products are capped at 0.4 mg of total THC per container. High-THCA flower sold as hemp today will not meet that definition, so from that date it is treated as marijuana under federal law, whatever state law says.

Bills to delay or repeal the change are in congressional committees, but none had advanced as of September 2026. Our explainer on the federal hemp THC limit covers the detail, and THCA vs delta-9 THC explains why heat turns THCA into delta-9.

Timeline of recent changes

• 12 December 2025: Operation Ganjapreneur seizures of marijuana, pre-rolls and THC products were announced.

THCA in neighbouring states

• Georgia: Flower over 0.3% total THC illegal

Carrying products across state lines can break the law of the state you enter, and federal law also applies. Check the destination state’s rules first.

Delta-8 in South Carolina

Delta-8 is treated differently: in South Carolina it is Illegal per Attorney General as of September 2026. Read our guide to Delta-8 law in South Carolina, or compare the two compounds in THCA vs Delta-8.

Frequently asked questions

Is THCA flower legal in South Carolina?

Not in practice. Officials test hemp after decarboxylation, which converts THCA into delta-9 THC, and flower above 0.3% on that basis is treated as marijuana. South Carolina has no legal marijuana market, so buying or selling high-THCA flower carries a real risk of drug charges.

Are hemp THC drinks legal in South Carolina?

The Attorney General’s September 2024 opinion said drinks with no more than 0.3% delta-9 THC on a dry weight basis are legal under the literal wording of state and federal law, but only laboratory testing can confirm a particular product. There is still no licensing, age or potency law for these drinks.

Does buying THCA online make it legal in South Carolina?

No. Where a product was bought does not change how South Carolina law treats it, and officials regard high-THCA flower as marijuana. Federal rules from 11 December 2026 will also count THCA toward the hemp limit nationally, removing high-THCA flower from the legal hemp market.
