THCa (tetrahydrocannabinolic acid) is the precursor to THC (tetrahydrocannabinol) and is found in raw, unheated cannabis plants. THCa flower refers to cannabis buds that have not undergone the decarboxylation process, meaning they haven't been exposed to heat to convert THCa into THC. As a result, THCa itself is non-psychoactive. When put under heat, THCa converts to THC.

Consuming THCa-rich flower, often in the form of raw cannabis or tinctures, is not known for producing the typical "high" associated with THC. Some users claim potential therapeutic benefits, including anti-inflammatory and neuroprotective properties. It's essential to note that research on THCa is still in its early stages, and individual responses may vary.
