Cannabinoid system as a potential target for drug development in the treatment of cardiovascular disease.

Although cannabinoids have been recreationally employed for thousands of years, it was not until the discovery of their specific receptors, in the early nineties, that the molecular basis of cannabinoid activity have began to be understood. Growing research in this field has demonstrated not only that the action of cannabinoids in mammals is mainly receptor-mediated, but also that endogenous cannabinoids, such as anandamide, are produced, metabolized, and taken up across the cell membrane through a facilitated uptake process. The exogenous administration of cannabinoids, as well as the manipulation of their endogenous levels have been related to a variety of effects, such as analgesia, impairment of cognition and learning, appetite enhancement and peripheral vasodilation.
