Explanation of your Endocannabinoid System

In a study in 1988 at the St. Louis University School of Medicine Dr. Allyn Howlett and Dr. William Devane determined that the mammalian brain has receptor sites that respond to compounds found in cannabis (CB1 to be specific). These receptors, named cannabinoid receptors turned out to be the most abundant type of neurotransmitter receptor in the brain. The discovery of these receptors resulted in the uncovering of naturally occurring neurotransmitters called endocannabinoids.
