"The role of the endocannabinoid system in the control of GI functions under physiological and pathological conditions has recently received increased interest. Within the last 5 years, more than half of all studies on the roles of the endocannabinoid system in the GI tract have been published. The current state of knowledge of the physiology and pharmacology of cannabinoids has largely increased, providing new potential tools for the treatment of several GI diseases. The symptoms of the most common GI disorders, IBS and inflammatory bowel disease, affect more than 20% of the population in Western countries and cause great discomforts [106]. Intestinal cramping, nausea, chronic diarrhoea and inflammation are all symptoms onto which the cannabinoids may be effective. Cannabis derivatives and other newly developed cannabinoids may represent promising tools for the treatment of different GI disorders because they can act at multiple sites, covering a wide spectrum of symptoms."
