Researchers have discovered a new cannabinoid receptor, CB3, one that could open a new door of healing possibilities. Before we go into more detail, let’s go over some brief history: After the U.S. government belatedly allowed scientists to move forward in research of the possible medical uses of cannabis, whole dimensions of human biochemistry which formerly existed in the shadows suddenly shifted into the light. In the 1990s, the discovery of the endocannabinoid system came about—a vitally essential component of the central nervous system that plays a role in everything; from cognitive processes and pain sensation to appetite regulation and physical activity. It was the discovery of the decade. In a phenomenally narrow window, science has gained a deeper comprehension of how the mammalian body manages and regulates itself. Because the endocannabinoid system grasps various domains of the human experience, it is a gargantuanly productive ground for research. The biggest focus in the endocannabinoid system is two cannabinoid receptors most commonly referred to as CB1 and CB2. These receptors are where the magic happens. Like all biochemical receptors, CB1 and CB2 are protein molecules that receive chemical signals from outside the cell. Think of them like the area on your television that you point the remote control at. They sit dormant until they receive a signal, then they spring into action.
