What is the endocannabinoid system?
The active constituents of cannabis, the cannabinoids, control receptors in the human body. These receptors then stimulate cells to perform certain functions. Up to now, two receptors that respond to cannabis have been identified: CB-1 and CB-2. The CB-1 receptors are found mainly in the central nervous system (brain and spinal cord). CB-2 receptors are found mainly in cells of the immune system.
The human body also produces its own substances that can bind to the CB-1 and CB-2 receptors. The interaction between these substances and the receptors is also referred to as the endocannabinoid system. The endocannabinoid system was not discovered until the nineteen-nineties.
