The endocannabinoid system is a biochemical communicative network that is found within all major systems in the human body. Endocannabinoid systems are actually found within all mammals, fish, reptiles, amphibians, and birds. This complex system of lipid-based retrograde neurotransmitters is responsible for regulating vital functions throughout our physiology. The recent discovery of the endocannabinoid system has changed our understanding of brain chemistry as well as healing properties among human biology.
Mechoulam, the scientist who discovered the endocannabinoid system, has stated that his cannabis research is solely responsible for finding this new physiological system that has immense importance. By studying how and why our physiology reacts to cannabis, we were able to discover cannabinoid receptors as well as endocannabinoids.
