THCA is a non-psychoactive chemical found in raw cannabis.
Contrary to popular belief, THC is not the most plentiful chemical in marijuana. In fact, marijuana flowers hardly contain any THC at all.
Instead, THC is mostly present in the cannabis plant as a different compound called tetrahydrocannabinolic acid (THCA).
Have you ever tried to eat raw cannabis? If you have, you’ll know that cannabis in its raw form can’t get you high. That’s because THCA is non-psychoactive and must be converted to THC to have any noticeable effect.
THCA becomes THC when you add heat, such as by smoking or vaporizing your cannabis, through a chemical process called decarboxylation.
