The endocannabinoid system acts as a neuromodulator, interacting with other neuromodulators such as the opioids. It influences all vital body functions and sets the tone of every conscious thought and feeling. It operates largely below conscious levels but occasionally floats into consciousness where it is perceived as perfect bliss and pain-free calm.
