Cannabigerol (CBG) is non-psychoactive but still contributes to the overall effects of cannabis. Cannabigerol is sometimes called the “mother of all cannabinoids”. This is because other cannabinoids are derived from cannabigerolic acid (CBGA), an acidic form of CBG. The most common cannabinoids that are found in cannabis plants include cannabidiol (CBD) and tetrahydrocannabinol (THC).
