The first demonstration that CB2 receptors are highly up-regulated in the cirrhotic liver, and the antifibrogenic role of CB2 receptors play during chronic liver injury, was detailed in the study, Antifibrogenic role of the cannabinoid receptor CB2 in the liver. Antifibrogenic role of the cannabinoid receptor CB2 in the liver.

Most recently, it has been shown that, "a single ultralow dose THC can reduce the apoptotic, oxidative and inflammatory injury induced by hepatic I/R injury. THC may serve as a potential target for therapeutic intervention in hepatic I/R injury during liver transplantation, liver resection and trauma".
