The human body utilizes a complex regulating system called the endocannabinoid system. CBD effects the system by blocking enzymes that usually break down the cannabinoids that the body produces; CBD also stimulates the opioid center in the brain that controls pain and serotonin release, which is a large part of mood regulation. The CB2 receptors that are mainly affected are located in areas like the: Gut, Kidney, Pancreous, Skeletal system, Muscles, Immune System, Reproductive System, Eyes, Liver, Respiratory System, Skin, Central Nervous System and the Heart. The three main methods of absorbing CBD are through consumables, topicals and smokables.
