CBD is fairly new to the market, and has become very popular in a short period of time. CBD stands for cannabidiol, which is a type of cannabinoid – one of approximately 100 that have been identified by scientists. Some other cannabinoids that may be found in CBD products are THC, or tetrahydrocannabinol, CBN, or cannabinol, CBG or cannabigerol, and CBC, or cannabichromene.
