Endocannabinoid System (ECS) Infographic slide breaking down the Endocannabinoid System (ECS) as a dietary precursor-driven symbiotic homeostatic suprasystem, with sequential symbols: a fork and knife for 'dietary' (fueled by food nutrients), a building block for 'precursor-driven' (built from fatty acids), reciprocal arrows with gut microbes for 'symbiotic' (mutual interaction with microbiome), a yin-yang for 'homeostatic' (maintains internal balance), and a network diagram for 'suprasystem' (integrates multiple organ systems)

The Endocannabinoid System: Dietary Precursor-Driven ECS & Medical Education Gap

Posted on By Stefan Broselid

The Misunderstood Master Regulator The endocannabinoid system (ECS) is often considered the “cannabis system,” but this label ignores its true—and far broader and more important—role in holistic health. Instead of being defined by external substances, the ECS is a dietary precursor-driven, symbiotic, homeostatic suprasystem: a dynamic physiological network that maintains body-wide…

Commentary Split-screen illustration showing cannabis as a small spark near a heart icon, symbolizing media hype on minor ECS changes and cardiac risks, contrasted with diet as a large bonfire fueled by junk food, representing precursor-driven ECS overdrive and chronic heart inflammation.

Beyond the Buzz: Cannabis Heart Risks vs. Diet-Driven ECS Overload

Posted on By Stefan Broselid

Introduction: Beyond the Buzz – A Flawed Focus on Cannabis Recent headlines have lit up with warnings about cannabis and heart health, fueled by a systematic review showing links to increased risks of strokes, heart attacks, and cardiovascular death. It’s easy to get caught up in the alarm. After all, who doesn’t want to protect their ticker? But here’s where our reasoning goes off track:…

An Update on Endogenous 2-AG Signaling: New Mechanisms and Cellular Integration

Posted on By Stefan Broselid

Introduction: The Evolution of an Idea When I first began my career in molecular pharmacology, the endocannabinoid system (ECS) quickly became a source of intrigue. Here was a unique receptor system, defined by its enigmatic lipid messengers and central role in brain physiology. Like many, I was trained to see 2-arachidonoylglycerol (2-AG) as a classic retrograde messenger, acting through G protein-coupled receptors (GPCRs), and to view intracellular signaling as a tightly…

Endocannabinoid System (ECS) Paracetamol as an Analgesic DAGL Inhibitor – Mechanism Confirmed by Jesus et al. 2025 Preprint

Paracetamol Confirmed as a Direct Analgesic DAGL Inhibitor: New Preprint Evidence

Posted on By Stefan Broselid

Important Note: This blog post discusses findings from a recent scientific preprint, meaning the research has not yet been formally peer-reviewed. Preprints allow for rapid dissemination of findings, but results should be interpreted cautiously until confirmed by peer-reviewed publication. Recently, we reported on a surprising new way that paracetamol (also known…

The Adiposity Filter: How Maternal Body Fat Reshapes Milk PUFAs for Your Baby’s ECS

Posted on By Stefan Broselid

At ECS.education, we’ve previously delved into how maternal metabolism and milk composition program infant development, the profound impact of maternal diet on the endocannabinoidome and infant health, and the links between ECS dysfunction, conditions like autism, and metabolic syndrome. Today, we explore compelling new research that adds another crucial layer to this understanding:…

Seeing is Believing: New Tech Reveals How The Endocannabinoid System Works in Real-Time

Posted on By Stefan Broselid

A paradigm-shifting review in Neuron (Malhotra et al., 2025) highlights how new technologies allow scientists to visualize endocannabinoid (ECS) dynamics in real-time in behaving animals. This post breaks down the key breakthroughs, including the central role of 2-AG in rapid signaling, its precision, its function in memory and seizures, and the implications for healthcare professionals and medical cannabis.
