The endocannabinoid system, plainly

Your body already runs a signaling system that cannabinoids interact with. A plain-language tour, no jargon required.

Long before anyone ate a gummy, your body was running its own cannabinoid system. It’s called the endocannabinoid system, or ECS, and it was only identified in the late 1980s and early 1990s.

Three moving parts

Messengers. Your body makes its own cannabinoid-like molecules, called endocannabinoids. The two best known are anandamide and 2-AG.

Receivers. Those messengers bind to receptors. The two main ones are CB1, found mostly in the brain and nervous system, and CB2, found mostly in the immune system and the rest of the body.

Clean-up crew. Enzymes break the messengers down once they’ve done their job, so signals stay short and local.

Where plant cannabinoids come in

Cannabinoids from the cannabis plant can interact with this same system. THC, for example, binds to CB1 receptors, which is a big part of why it’s intoxicating. Other cannabinoids interact with the system in different, often subtler ways, and researchers are still mapping many of them.

Why this matters for GURU

This is why we talk about vibes, not strains. Different cannabinoid combinations interact with the system differently, so each GURU vibe pairs THC with a different supporting cast. It’s also why we say effects vary: everybody’s system is a little different.
