Cannabis is a very complicated plant. Made up of hundreds of chemical compounds called cannabinoids – more than 100 of which have been identified and cause different effects – these cannabinoids bind to receptors already in the body, making up what is called the endocannabinoid system(ECS). Endocannabinoid receptors, called CB1 and CB2, are located all throughout the body, including the brain, nervous system, skeletal muscles, skin, immune system, heart, blood vessels, kidneys, and digestive tract. Different cannabinoids have shown a variety of beneficial effects, ranging from anti-anxiety to weight loss.
