In a fascinating deep dive into human physiology, Dr. Rowan Thompson, resident doctor and Vice Chair of the Medical Cannabis Clinicians Society (MCCS), explores the Endocannabinoid System (ECS)—a complex biological network that remains largely untaught in medical schools despite its pivotal role in maintaining internal balance, or homeostasis.
What is the endocannabinoid system?
The ECS is a wide-ranging signaling system involved in regulating everything from mood and appetite to inflammation and memory. It consists of three primary components:
-
Endocannabinoids: Lipids produced on demand by our bodies, the most famous being Anandamide (AEA) and 2-AG.
-
Receptors: Proteins found throughout the body, specifically CB1 (concentrated in the brain and central nervous system) and CB2 (found primarily in the immune system).
-
Enzymes: Molecules like FAAH and MAGL that break down endocannabinoids once they have fulfilled their signaling function.
You are what you eat: the diet connection
One of Dr. Thompson’s most compelling points is the direct link between our diet and ECS health. Endocannabinoids are synthesised from fatty acids. The modern Western diet, which is heavily skewed toward Omega-6 fatty acids (found in vegetable oils) and deficient in Omega-3s, may be driving a state of “Endocannabinoid Hypertonia.”
Research suggests that high Omega-6 intake leads to overactive ECS signalling, which is strongly associated with metabolic syndrome, obesity, and chronic inflammation. Conversely, increasing Omega-3 intake can produce “less potent” endocannabinoids that may help restore balance.
Clinical implications and future horizons
The ECS is implicated in a vast array of conditions. Dr. Thompson highlights that “low ECS tone” is often observed in patients with:
-
Fibromyalgia
-
Migraines
-
Irritable Bowel Syndrome (IBS)
On the other hand, overexpression of receptors like CB1 in cardiac tissue is observed in individuals with obesity, suggesting that the ECS is a prime target for treating metabolic diseases.
Closing the education gap
Perhaps the most urgent takeaway is the need for medical education. Currently, the ECS is not part of the standard curriculum in UK medical schools. As medical cannabis becomes a more prevalent treatment option, understanding this “master regulator” is no longer optional— it is essential for the future of metabolic and physiological medicine.
