Understanding — The Endocannabinoid System
The Endocannabinoid System
The endocannabinoid system is the biological infrastructure that connects cannabinoid research to human physiology. These nine articles build from first principles — what the system is, how its receptors and signaling molecules work, and how it intersects with stress. Readers who work through this pillar find the Health Topics research considerably more legible.
What Is the Endocannabinoid System?
The body has its own system of chemical messengers that help regulate stress, sleep, pain, and mood — here's what it is and why researchers study it.

Endocannabinoid Receptors: CB1, CB2, and Beyond
How the body's cannabinoid receptors work, where they are found, and why their location matters for understanding cannabinoid research.
Endogenous Cannabinoids: Anandamide and 2-AG
Your body produces its own cannabinoid-like molecules — what they are, what they do, and how they relate to plant-derived cannabinoids.
Anandamide and the Stress Response
How one of the body's own cannabinoid molecules interacts with the stress response, and what research has found about what happens when that system is disrupted.
FAAH and Enzyme Regulation
The enzyme that breaks down anandamide — what it does, why it matters for cannabinoid research, and how CBD interacts with it.
Beyond CBD: The Phytocannabinoid Landscape
CBD is one of more than a hundred cannabinoids found in the hemp plant — what the others are, and what early research has begun to explore.
Full-Spectrum, Broad-Spectrum, and Isolate
Three different ways of preparing hemp — what each one contains, how they differ, and why the distinction matters for reading research and product labels.
The Aging Endocannabinoid System: What Research Has Found
CB1 receptor density and endocannabinoid production change with age — what research documents about ECS changes across the lifespan and what it means for reading cannabinoid research.

Clinical Endocannabinoid Deficiency: The Research Hypothesis
Neurologist Ethan Russo proposed that migraine, fibromyalgia, and IBS may involve chronically low ECS tone — what the correlational evidence shows and what it does not establish.
