THCa vs THC: what is the difference?

THCa (tetrahydrocannabinolic acid) is the acid precursor of THC (tetrahydrocannabinol). Heat turns THCa into THC: the reaction is called decarboxylation, and it happens slowly as flower dries and quickly when it is smoked or cooked.

Freezo sells THCa flower online at shopfreezo.com: 20 uncoated strains and 10 diamond coated strains. Updated October 1, 2026. Stock and prices change; the product pages are the current record.
