Is THCA Legal? Understanding Hemp Laws & THC Testing
The legality of THCA depends on how hemp products are tested and classified under federal law. THCA itself is not explicitly listed as a controlled substance.
Federal Hemp Law
Under the 2018 Farm Bill, hemp products are federally legal if they contain no more than 0.3% Delta-9 THC by dry weight. This definition does not directly reference THCA.
Why Testing Matters
Most compliance testing measures Delta-9 THC before heat is applied. Because THCA has not yet converted, products may test compliant despite having high potential THC levels.
State-Level Considerations
Some states apply additional rules or total THC calculations. Consumers should always stay informed about local regulations.
