In 2002 Maurice Elphick of Queen Mary University in London presented his research at the annual meeting of the Society for Experimental Biology. Elphick had previously ​demonstrated that the cannabinoid system in mammals "is a fundamental signalling system in the central nervous system of vertebrates, where it plays a role in movement, pain, and learning and memory.” The 2002 presentation built on his previous work. He had discovered cannabinoid receptors outside of the nervous system among invertebrates, specifically sea squirts. This means that the receptor for cannabinoids existed much earlier in the evolutionary line than previously estimated. Cannabinoids have served a biological function in animals since invertebrates evolved (Genomeweb, 2002).

The Endocannabinoid System 

The endocannabinoid system is the largest neurotransmitter system in the brain. This system can be affected either by cannabinoids from outside of the body (exogenous), or those…
