The endocannabinoid system or the endogenous cannabinoid system was named after cannabis because the plant led to the discovery of this crucial physiological system. The system is made of up endocannabinoids and cannabinoid receptors, which help regulate many of our most basic functions like sleep and appetite. Endocannabinoids are naturally produced in the body and cannabis consumption increases the amount of endocannabinoids present in the body. The function of endocannabinoids and their receptors is to maintain homeostasis from the organism to the cell level by reversing damage in whatever way possible.
What are cannabinoid receptors?
The CB receptors can be found throughout the body, and there are two main kinds: CB1 and CB2 receptors. CB1 receptors are mostly found in the brain with some present in the lung, kidney, liver, fat, heart, muscle, and bone. CB2 receptors are primarily found in the immune system, and blood cells but both can be found in the same tissues providing different functions. CB1 receptors are mostly responsible for the psychoactive and euphoric effects of THC. On the other hand, CB2 receptors mostly work in the immune system, but they are also present in the liver, gut, muscle, and bone.
Generally speaking the CB1 and CB2 receptors cause healing properties when activated within the areas of the body they are located. Receptors are similar to locks, and the cannabinoids are the keys.The activity of CB1 and two receptors usually reverses the damage done to the body, returning it to homeostasis. This also applies to mental health damage because endocannabinoids can aid in balancing mood and creating euphoria.
The balance between CB1 and CB2 inhibition and activation by cannabinoids is important. Heavy CB1 inhibition may lead to an increased risk of depression, mood disturbance, and immunosuppression. However, if CB1 over-activates there is an increased risk of psychoactivity, systemic inflammation, cardiovascular risk, diabetes, and obesity.
