Despite all the progress achieved in the treatment of chronic gastrointestinal diseases, in some patients the treatment does not reach long-term optimum effectiveness. Therefore a number of patients have turned to complementary and alternative medicine (CAM). Of the different types of CAM patients with GIT diseases tend to prefer in particular homeopathy, acupuncture and not least phytotherapy, where therapeutic use of cannabis may also be included. The pathophysiological basis of therapeutic effect of curative cannabis has not been fully clarified so far. Many scientists in many fields of medicine and pharmacology have been engaged in the study of effects of cannabinoids on the body since the beginning of the 20th century with the interest significantly increasing in the 1980s. 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.
