What Tennessee law says about THCA

Public Chapter 526 of 2025 lists THCA as a hemp-derived cannabinoid, but the Tennessee Alcoholic Beverage Commission (TABC) applies a total-THC standard to its licensees: total THC equals THCA multiplied by 0.877 plus delta-9 THC, and products above 0.3% are illegal¹. The statute also makes it a Class A misdemeanour to manufacture or sell hemp products containing more than 0.3% delta-9 THC². Because THCA flower typically contains far more than 0.3% THCA, it cannot meet the limit.

Retailers holding older Department of Agriculture licences were allowed to keep selling under the previous rules until 30 June 2026. The TABC finalised its rules in May 2026, and the THCA restriction took full effect on 1 July 2026¹³. Since then, flower, pre-rolls and vapes that exceed the total-THC limit have had to leave licensed shelves.

Tennessee has neither adult-use nor medical marijuana, so there is no licensed channel for high-THCA products³. Low-THC hemp products that pass the total-THC test may still be sold by TABC-licensed retailers to adults 21 and over, in person, with flower limited to half an ounce per package². The federal total-THC definition from 11 December 2026 matches Tennessee’s approach⁴.

How the federal hemp change affects Tennessee

Separate from Tennessee 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

• 1 July 2026: The THCA restriction took full effect as older Department of Agriculture licences expired.
• May 2026: The TABC finalised its hemp rules, including the total-THC formula.

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 Tennessee

Delta-8 is treated differently: in Tennessee it is Legal 21+, ABC-licensed stores as of September 2026. Read our guide to Delta-8 law in Tennessee, or compare the two compounds in THCA vs Delta-8.

Frequently asked questions

When did THCA become illegal in Tennessee?

The restriction took full effect on 1 July 2026. Public Chapter 526 moved hemp oversight to the TABC on 1 January 2026, but retailers with older Department of Agriculture licences could keep selling until 30 June 2026. TABC rules finalised in May 2026 count THCA toward the 0.3% total THC limit.

Can I still buy THCA flower in Tennessee?

Not legally if it exceeds 0.3% total THC, which covers nearly all THCA flower sold as hemp. Licensed retailers may only sell hemp flower that passes the total-THC test, in packages of no more than half an ounce, to adults 21 and over.

How does Tennessee calculate total THC?

The TABC uses the formula total THC = (THCA x 0.877) + delta-9 THC. The 0.877 factor reflects the weight THCA loses when it converts into delta-9 THC on heating. Products whose result exceeds 0.3% are illegal for TABC licensees to sell.
