This model contains a biallelic disruption of the Faah gene encoding the fatty acid amide hydrolase. FAAH is a serine hydrolase responsible for the breakdown of endocannabinoids. This model is useful for the study of cannabinoid biology including nociception.

Cannabinoids perform a variety of functions including the regulation of nociception. FAAH KO rats lack the enzyme responsible for endocannabinoid degradation,and endocannabinod levels should be elevated in this model.
