Decarboxylation is a crucial process in marijuana production where heat is applied to activate cannabinoids like THC. This chemical transformation converts non-psychoactive tetrahydrocannabinolic acid (THCA) into psychoactive THC, significantly enhancing the potency and enabling the product to induce desired effects when consumed. Proper decarboxylation ensures that the cannabinoids are in their active form, maximizing the therapeutic potential of marijuana-infused products.
