THC-A, tetrahydrocannabinolic acid is an inactive compound naturally found in the plant trichomes. Special refining processes isolate the compound from plant material reaching potencies of 95%+. What makes THCa isolates even more unique is the lack of other compounds from raw plant material. THCa products are able to achieve a white or nearly clear coloring, due to removing terpenes, flavonoids, and fats.
