What is the endocannabinoid system?

The endocannabinoid system is a complex system composed of membrane receptors (CB1 and CB2), ligands, and enzymes found in mammals, including humans.

It plays a crucial role in regulating various physiological and homeostatic functions in the body.

The term “endocannabinoid” refers to compounds naturally produced by the body that activate this system. A dysfunctional endocannabinoid system can lead to or worsen certain diseases.

The endocannabinoid system


The 3 components of the ECS

The ECS is involved in regulating many biological functions, including sleep, appetite, the immune system, pain response, mood, and more. Endocannabinoids act as chemical messengers in this system, binding to receptors to signal changes in the cellular environment and help maintain the body’s internal balance, a process known as homeostasis.

#1• Endocannabinods receptors

The ECS includes CB1 and CB2 cannabinoid receptors found throughout the body. Their activation—by endocannabinoids (anandamide and 2-AG) or cannabinoids (CBD, CBG, CBN)—can be beneficial to health.


#2• Enzymes

These enzymes are responsible for breaking down endocannabinoids after they’ve been used. The two main enzymes are FAAH (fatty acid amide hydrolase) for anandamide and MAGL (monoacylglycerol lipase) for 2-AG.

#3• Endocannabinoids

These are lipid-based compounds naturally produced by the body. The two main endocannabinoids identified so far are anandamide and 2-arachidonoylglycerol (2-AG).

Clinical Endocannabinoid Deficiency

Clinical endocannabinoid deficiency can occur due to a lack of endocannabinoid production or a deficiency in CB1 or CB2 receptors. In both cases, this may trigger or worsen certain conditions.
