Introduction:

Although cannabinoids have been used for several years, only recently have their mechanisms of action and therapeutic targets been described. Alterations in the endocannabinoid system have been observed in various diseases and conditions such as pain, inflammation, autoimmune diseases and various specific disorders. Inflammatory bowel disease groups two chronic idiopathic conditions with uncertain pathogeneses in which deregulation of the immune system plays an important role. Alternative treatments need to be developed for these patients since only a minority of patients achieve disease remission. Our goal is to review recent evidence related to the use of cannabis to treat ulcerative colitis and Crohn’s disease.

Methods:

This is a focused narrative review based on searches of Pubmed and Embase. Relevant articles have been reviewed and summarized in narrative form.

Results:

The two main components of cannabis, CBD and THC, have been extensively studied, and their anti-inflammatory and antinociceptive effects have been tested. The effects of these components for control of the symptoms of ulcerative colitis and Crohn’s disease have been widely described. However, high quality studies are needed to continue evaluating the efficacy and safety of cannabis use in patients with inflammatory bowel disease.
