Hi!

It is a fact that the human body produces endocannabinoids. The 2 most studied are called anandamide and 2-Arachidonoylglycerol although there are others.

Many things can trigger the production of endocannabinoids which is, by the way, "on demand". The endocannabinoid system is mostly thought of as having a protective role, so stress signals can increase the levels of endocannabinoids.

The endocannabinoid system regulates all other systems in the body, from nervous system, to digestive, reproductive, immune ... I don't think there is a system in our bodies that does not involve regulation by endocannabinoids.
