THC-A is the shorter term for tetrahydrocannabinolic acid, THC's non-intoxicating precursor. While it won't get you high, THC-A is anti-inflammatory, anti-tumor, antispasmodic, and it boosts appetite and sleepiness. THC-A converts into THC when cannabis is dried and cured. You're more likely to find higher concentrations of THC-A in raw cannabis and isolates.
