Quick answer: It is unclear. South Carolina’s hemp law only measures delta-9 THC, so on paper THCA flower under 0.3% delta-9 THC fits the hemp definition. But the Attorney General and SLED (the state police) have said they disagree with that reading, and they have seized hemp products. Federal law will count THCA from December 11, 2026.
Here is where THCA stands in South Carolina as of November 2026, including the federal change that takes effect on December 11, 2026.
South Carolina THCA Key Dates
- 2019: South Carolina passes its Hemp Farming Act, using the 0.3% delta-9 THC standard.
- July 2019: An Attorney General opinion on raw hemp flower leaves its legal status to law enforcement.
- December 2025: The Attorney General and SLED announce a statewide THC enforcement operation, with indictments and seizures.
- 2026 session: The Senate passes hemp beverage and edible rules; no hemp bill becomes law as of May 2026.
- December 11, 2026: Federal total-THC rule takes effect.
South Carolina THCA Law as of November 2026
South Carolina defines hemp as cannabis with no more than 0.3% delta-9 THC by dry weight. The law does not mention THCA, and the state has not passed a total-THC test or a ban on smokable hemp.
That would make compliant THCA flower hemp on paper. But Attorney General Alan Wilson and SLED have publicly opposed that reading. In December 2025 they announced a state grand jury investigation that led to indictments and large seizures of hemp products.
Because of that conflict, THCA flower is a legal gray area in South Carolina.
Age Limit in South Carolina
South Carolina has no clear statewide minimum age for hemp flower as of November 2026. HIGH THCA sells only to adults 21 and over.
Pending Changes in South Carolina
The 2026 session saw bills to regulate hemp THC drinks and edibles, including age limits and sales through licensed stores. None passed both chambers as of May 2026. Watch for new bills in the 2027 session.
Federal Change
Separately, federal law changes on December 11, 2026. From that date, federal law counts THCA toward the 0.3% THC limit and caps finished products at 0.4 mg of total THC per container. Most THCA flower will no longer count as hemp under federal law. Read The 2026 Hemp Ban for details.
What This Means for Buying THCA Flower in South Carolina
South Carolina adults face real legal risk with THCA flower, even though the hemp statute only measures delta-9 THC. State officials treat it as marijuana in practice.
If you are in South Carolina, read the current law and recent guidance from the Attorney General’s office before buying.
How to Check a COA
A Certificate of Analysis (COA) is the lab report for a product batch. It shows how much of each cannabinoid is in the product.
- Delta-9 THC: the percentage of delta-9 THC by dry weight.
- THCA: the percentage of THCA.
- Total THC: usually delta-9 THC + (0.877 x THCA).
- Batch number: should match the product you buy.
Every HIGH THCA product is lab tested and has a COA. See them on our Certificate of Analysis page.
Does HIGH THCA Ship to South Carolina?
No. Our checkout does not accept South Carolina addresses for THCA flower, pre-rolls or concentrates. See our shipping policy for details.
