The word is out—and the fight is on—for civilization to prove that cannabis, also known as marijuana, could be the next super-drug. What fascinates me most is that our bodies are equipped with a pre-built system designed to interact with cannabinoids, known as the endocannabinoid system. This system responds to compounds found in plants like marijuana. My interest in endocannabinoids began when I learned they play a key role in producing the “runner’s high” that long-distance and endurance athletes know so well. When I started exploring this system—initially out of curiosity about the euphoric effects triggered by running—I discovered a wealth of powerful information that few people seem to talk about. Join me in this exploration and prepare to be fascinated by a system that rivals, and in many ways surpasses, our immune system in complexity and impact.
