The Endocannabinoid System

Your Body's Cannabis System

The endocannabinoid system (ECS) is a biological system present in all mammals. Discovered in the 1990s, it plays a crucial role in regulating mood, sleep, appetite, pain, immune function, and more.

Key Components

The ECS has three main parts:

Endocannabinoids are molecules your body naturally produces that are structurally similar to plant cannabinoids. The two primary endocannabinoids are anandamide (the "bliss molecule") and 2-AG.

Receptors are found throughout your body. CB1 receptors are concentrated in the brain and nervous system, while CB2 receptors are primarily in immune cells and peripheral organs.

Enzymes break down endocannabinoids after they've served their purpose. FAAH breaks down anandamide, and MAGL breaks down 2-AG.

How Cannabis Interacts

When you consume cannabis, plant cannabinoids (phytocannabinoids) interact with this system:

• THC binds directly to CB1 receptors, producing its psychoactive effects
• CBD doesn't bind directly but modulates how other cannabinoids interact with receptors
• Other cannabinoids and terpenes influence the ECS in various ways

Why It Matters

Understanding the ECS helps explain why cannabis affects everyone differently. Factors like your natural endocannabinoid levels, receptor density, and enzyme activity all influence your response to cannabis.
