THCA (Tetrahydrocannabinolic Acid)

The non-psychoactive precursor to THC found in raw, unheated cannabis. THCA is the most abundant cannabinoid in fresh flower. It is not intoxicating on its own but converts to psychoactive delta-9 THC when heated (smoked, vaped, or cooked) through a process called decarboxylation. Under the 2018 Farm Bill, THCA hemp flower is federally legal if the plant's delta-9 THC content is ≤0.3% by dry weight.
