Quick answer: Probably not. Most sources say Mississippi treats hemp-derived THC products sold outside its medical cannabis program as illegal, based on state drug law and a 2025 Attorney General opinion. Some retailers still sell THCA flower, so the status is disputed. Federal law will count THCA from December 11, 2026.
Here is where THCA stands in Mississippi as of November 2026, including the federal change that takes effect on December 11, 2026.
Mississippi THCA Key Dates
- 2020: Mississippi passes its hemp program law.
- 2022: Mississippi creates its medical cannabis program.
- June 2025: An Attorney General opinion says most hemp products for human consumption are illegal outside approved channels.
- 2026 session: A bill to regulate hemp THC products (HB 1502) dies.
- December 11, 2026: Federal total-THC rule takes effect.
Mississippi THCA Law as of November 2026
Mississippi law keeps high-THC cannabis on its controlled substances schedule. A June 2025 Attorney General opinion said hemp-derived products for people to consume are generally illegal unless they come through the medical cannabis program or are FDA-approved.
Some stores still sell THCA flower, and some sources call it legal. Because of the AG opinion, THCA flower carries real legal risk in Mississippi.
Age Limit in Mississippi
Mississippi has no separate hemp age law that clearly covers THCA flower. HIGH THCA sells only to adults 21 and over.
Pending Changes in Mississippi
A 2026 bill to set up rules for hemp THC products did not pass. Watch 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 Mississippi
The weight of current guidance says THCA flower is not a legal retail product in Mississippi. Check with a Mississippi attorney before you buy.
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.
