But experts believe that cannabis can actually help. Cannabinoid receptors CB1 and CB2 are found in every single human body. They are also found in the central nervous system and the brain, and they have been studied for the role they play in our overall health, irritability, pain, and other conditions. What’s interesting is that studies discovered, in obese people, CB1 receptors are more common particularly in fatty tissue. This has led researchers to believe that there is an association between obesity and CB1 receptor activation.
