THCA
THCA (tetrahydrocannabinolic acid) is a natural compound found in raw cannabis plants. It does not cause a high unless it is heated.
Example: Fresh cannabis leaves contain THCA.
THC
THC (tetrahydrocannabinol) is the active compound formed when THCA is heated. It affects the brain and produces psychoactive effects.
Example: Smoking cannabis converts THCA into THC.
