Compared to THC, CBD has very different properties. It weakly binds to both CB1 and CB2 receptors in the brain and body, gently stimulating and blocking them at the same time. This not only mildly activates the receptors, but is also thought to trigger the body to create more CB1 and CB2 receptors, a process known as upregulation. It also results in increased natural levels of anandamide.
