The primary distinction between THCa and THC lies in their chemical structures and resultant effects on the body. THC is responsible for eliciting a high sensation, interacting with cannabinoid receptors in our brain and nervous system. On the other hand, THCa is non-euphoric, and does not produce a high when consumed in its raw form. However, it's crucial to note that upon being subjected to decarboxylation, THCa transforms into THC, releasing the psychoactive properties hidden within.
Decarboxylation is a heat-driven process that transforms THCa into THC, enabling its psychoactive properties. Methods used for the decarboxylation of THCa range from smoking, vaping, dabbing to cooking/baking, and even exposure to sunlight. The application of heat allows the cannabinoid to lose a carboxyl group and transition from its acid state (THCa) to its potent state (THC).
