Tetrahydrocannabinolic acid (THCA) is not really your typical THC. It's the cannabinoid precursor to THC. When it is subjected to mild or heat, it undergoes a system termed decarboxylation, which ends up in it shedding its carboxyl group and turning it into THC. With out THCA, there wouldn't be THC. https://hugox233dyt8.sunderwiki.com/user
