CBG stands for cannabigerol, which is a cannabinoid.
CBG is a pre-cursor to CBD and THC, which is why it is easily found in younger hemp plants. CBG can be compared to stem cells, which have the ability to develop into many different cell types and may work to repair damaged tissues. CBG has some ability to suppress the growth and development of bacteria.
Research is being conducted looking into the benefits and effects of CBG. As far as consumption is concerned, the smoke is less harsh and many benefits of CBD are still experienced, with even less of a change in perception.
