Endocannabinoid System
The Master Regulatory System
The endocannabinoid system (ECS) is one of the most widespread and important regulatory systems in the human body — yet it wasn't discovered until 1988. Present in all mammals for over 500 million years, the ECS uses cannabis-like molecules your own body produces to maintain balance across virtually every biological function. Cannabis works because it speaks the ECS's native language.
🗣️ In Simple Terms
Your body has a built-in system that controls mood, memory, pain, appetite, sleep, and immune function. Cannabis works because it speaks this system's language — that's why it affects so many different things at once.
