Key Facts

What is THCa?: THCa (tetrahydrocannabinolic acid) is the raw, non-psychoactive cannabinoid found in cannabis. When heated, it converts to Delta-9 THC via decarboxylation. Conversion formula: Total THC = (THCa × 0.877) + Delta-9 THC.
Is THCa Legal?: Hemp-derived THCa is federally legal under the 2018 Farm Bill when containing <0.3% Delta-9 THC by dry weight. State laws vary.
Price Difference: THCa products are typically 40–60% cheaper than dispensary THC due to no state cannabis tax, lower licensing costs, and a competitive online marketplace.
