What is THCa?
THCa is what actually exists in living cannabis plants—THC only forms when THCa is heated (decarboxylated). This means raw cannabis doesn't get you high. THCa has its own therapeutic properties distinct from THC: anti-inflammatory, neuroprotective, and anti-emetic effects without any intoxication. This has sparked interest in raw cannabis consumption (juicing) and THCa products. However, THCa is unstable and will slowly convert to THC even at room temperature, and rapidly when heated. This creates legal complications since THCa can easily become THC.
How It Works
THCa doesn't effectively bind to CB1 receptors due to its 3D shape (the carboxylic acid group prevents it), which is why it's non-psychoactive. It works through other pathways: COX-1/COX-2 inhibition (like ibuprofen), PPARγ receptor activation, and possibly GPR55 modulation.
