About THCA & the Farm Bill
The 2018 Agriculture Improvement Act (Farm Bill) legalized hemp federally, defining it as cannabis containing no more than 0.3% Δ9-THC on a dry weight basis. THCA (tetrahydrocannabinolic acid) is a non-psychoactive precursor to THC found in raw hemp; when heated (smoked, vaped, or dabbed) it converts to THC via decarboxylation, which is why a delta-9-only test let high-THCA flower qualify as hemp. That definition narrows to a total-THC standard on November 12, 2026.
Some states interpret their laws to include THCA in total THC calculations or treat high-THCA flower as equivalent to marijuana. Always check the most current state law before purchasing.
