As a cannabis plant grows, it produces cannabigerolic acid (CBGA), the precursor to the three main cannabinoid lines: THCA, CBDA, and CBCA.
When heat energy is added to CBGA, it undergoes a chemical reaction called decarboxylation (you know… “decarbing”) which drops the A from CBGA, converting it from cannabigerolic acid to cannabigerol.
Over time, most of a plant’s CBGA ends up converted into other cannabinoids, primarily THC or CBD, leaving about 1% CBG in the plant.
CBG and CBD are often compared because they both act on the endocannabinoid system and both are non-psychoactive, so they won’t alter your state of mind in the way THC will. CBG is generally reported as having a calming effect and doesn’t have any notable side effects, but even though it was first identified in 1964, studies on it didn’t begin until recently. The good news is that everything scientists are finding out about the cannabinoid is promising.
