Tetrahydrocannabinolic acid (THCA) is a non-psychoactive cannabinoid found in raw cannabis plants. It is the precursor to tetrahydrocannabinol (THC), the psychoactive component of cannabis. It has non-psychoactive properties, until converted to THC through decarboxylation (heating). Some of the benefits of THCA may include helping with inflammation, aid in nausea relief and appetite stimulation. It does not cause the mind altering effects that can be a concern for substance abuse.
