Cannabigerolic acid, or CBGA, is one of many cannabinoids produced by the cannabis plant and is considered the granddaddy of all cannabinoids. CBGA is a foundational cannabinoid compound that is at the very top of cascade reactions that occur when producing three of the major cannabinoid lines, including THCA, CBDA, and CBCA, which all eventually turn into THC, CBD, and CBC respectively. CBGA can also convert into CBG, although for most major strains, it typically converts into either THC or CBD.
