Dietary linoleic acid elevates endogenous 2-AG and
anandamide and induces obesity.
Effects of
anandamide on potassium channels in rat ventricular myocytes: a suppression of 1(to) and augmentation of K(ATP) channels.
Formation and inactivation of endogenous cannabinoid
anandamide in central neurons.
One of the primary cannabinoids is
anandamide, derived from the Sanskrit word meaning bliss.
Another similarity with the opioid system is the existence of endogenous cannabinoid receptor agonists, the most studied of which is
anandamide (Pertwee 2002).
Cannabinoids, like
anandamide, were tried successfully to reduce testicular IR injury (11).

9]-tetrahydrocannabinol and
anandamide antinociception in nonarthritic and arthritic rats.
Chronic ethanol increases the cannabinoid receptor agonist
anandamide and its precursor N-arachidonoylphos-phatidylethanolamine in SK-N-SH cells.
In contrast,
anandamide binds strongly to CB 1 (as strongly as THC from cannabis), whereas the Echinacea alkylamides only have a weak affinity for CB1 receptors (but perhaps sufficient to promote the sense of well-being that many patients report after taking Echinacea consistently).
Previous studies in other tissues have shown that
anandamide, an endogenous agonist of TRPV1, can induce vasodilation [Davis et al.
He describes chocolate as "an addicting drug, targeting the same spot in your brain as opiate drugs" and points out it contains caffeine, theobromine, phenylethylamine and
anandamide.
