Cannabis in liver disorders: a friend or a foe?

The recent legalization of recreational marijuana use in some parts of the world, the discovery of new indications for the clinical application of cannabis, and the acceptance of the use of cannabis in practice has been paralleled by extensive research on the active components of cannabis and the endocannabinoid system within the human body. All in all, the recent trends in research, clinical experiences, as well as the legislature, has opened up new avenues towards the widespread clinical application of cannabis and its derivatives as well as modifiers of the components of the endocannabinoid system. More research is required to fully exploit these new evidences.

Review article: the endocannabinoid system in liver disease, a potential therapeutic target

Endocannabinoids are a family of potent lipid-soluble molecules, acting on the cannabinoid (CB) receptors that mediate the effects of marijuana. The CB receptors, endocannabinoids and the enzymes involved in their synthesis and degradation are located in the brain and peripheral tissues, including the liver. The endocannabinoid system plays an important role in the pathophysiology of liver disease and its associated conditions. While some drugs targeting the endocannabinoid system have deleterious neurological adverse events, there is promise for a newer generation of therapies that do not cross the blood-brain barrier.
