The discovery of CB receptors (1988) and endogenous molecules which activate these receptors (1992) led to the discovery of the endocannabinoid system. Pharmacological modulation of the endogenous cannabinoid system offers new therapeutic possibilities of treatment of many illnesses and symptoms including the GIT disorders, including of nausea, vomiting, cachexia, IBS, Crohns disease and some other disorders. Cannabinoids are attractive due to their therapeutic potential – they affect a lot of symptoms with minimum side effects. Experience of patients with GIT disorders show that the use of cannabis is effective and helps in cases where the standard therapy fails.
