Tetrahydrocannabinolic acid (THCA, 2-COOH-THC; conjugate base tetrahydrocannabinolate) is a precursor of tetrahydrocannabinol (THC), an active component of cannabis. [1]THCA is found in variable quantities in fresh, undried cannabis, but is progressively decarboxylated to THC with drying, and especially under intense heating such as when cannabis is smoked or cooked into cannabis edibles.
THC acetate ester (THC-O or THCOA) can be synthesized from THC, [2] [3] or from THCA. The acetylation of THC does not change the properties of the compound to the same extent as with other acetate esters, as the parent compound (THC) is already highly lipophilic, but potency is nonetheless increased to some extent.
Tetrahydrocannabinolic acid (THCA) synthase (full name Δ 1-tetrahydrocannabinolic acid synthase) is an enzyme responsible for catalyzing the formation of THCA from cannabigerolic acid (CBGA). THCA is the direct precursor of tetrahydrocannabinol (THC) , the principal psychoactive component of cannabis , which is produced from various strains of ...

There is no evidence for enzymatic conversion of CBDA or CBD to THCA or THC. For the propyl homologues (THCVA, CBDVA and CBCVA), there is an analogous pathway that is based on CBGVA from divarinolic acid instead of olivetolic acid.
CBD heated to 175, [13] or 250–300 °C may partially be converted into THC. [14] Even at room temperature, trace amounts of THC can be formed as a contaminant in CBD stored for long periods in the presence of moisture and carbon dioxide in the air, with storage under inert gas required to maintain analytically pure CBD.
Many different ways to consume cannabis involve heat to decarboxylate THCA into THC; [33] [34] common modes include: Smoking , involves burning and inhaling cannabinoids ("smoke") from small pipes , bongs (portable versions of hookahs with a water chamber), paper-wrapped joints , tobacco-leaf-wrapped blunts , or the like.
11-Hydroxy-Δ 9-tetrahydrocannabinol (11-OH-Δ 9-THC, alternatively numbered as 7-OH-Δ 1-THC), usually referred to as 11-hydroxy-THC is the main active metabolite of tetrahydrocannabinol (THC), which is formed in the body after Δ 9-THC is consumed.
