CBD (short for Cannabidiol) is one of the most studied cannabinoids, second only to THC. Being non-psychoactive, CBD provides numerous benefits without THC's intoxicating effects. CBD promotes a good night's rest, aids in relief, balances mood, enhances relaxation, promotes recovery, supports the immune system and more. Cannabidiol (CBD for short) naturally occurs within the tiny hair like structures known as trichomes that grow on hemp and cannabis. The first cannabinoid molecule to be discovered in 1940, researchers have been studying CBD's numerous benefits ever since. Cannabidiol exists in two states, CBD and CBD-a.
