Unlike THC, which binds directly with cannabinoid receptor sites in your body's endocannabinoid system (ECS), THCA needs to be converted into THC by decarboxylation before it can bind with those receptors. Decarboxylation is a chemical process that removes a carboxyl group from an organic molecule. This process occurs naturally over time as cannabis ages or when heated through smoking or vaporizing. Therefore, if you want to experience the full effects of THCA flower, you need to first expose it to heat or age it so that its compounds can activate fully.
