Cannabis includes a material called cannabidiol (CBD). THC, the psychotropic element of marijuana, is missing from CBD. However, CBD as well as the endocannabinoid system connect. The endocannabinoid system regulates immunological reactions, mood, cravings, sleep, as well as pain. According to studies, CBD may be able to reduce chronic pain. Certainly, many studies recommend that CBD could even displace opiates as a painkiller.
