Introduction
The human body is equipped with a complex system known as the endocannabinoid system (ECS), which plays a crucial role in maintaining balance and homeostasis. At the core of this system are cannabinoid receptors, specialized proteins found throughout the body that interact with cannabinoids, including those produced internally (endocannabinoids) and those derived from external sources (phytocannabinoids). In this comprehensive guide, we will explore the fascinating world of cannabinoid receptors, their functions, and the implications for our overall well-being.
