How Marijuana Works in the Body?

Marijuana affects the body through the endocannabinoid system (ECS), a complex network of receptors involved in regulating mood, appetite, pain, memory and sleep.

Key Receptors:

• CB1 receptors: Primarily located in the brain and central nervous system; responsible for psychoactive effects.
• CB2 receptors: Found mostly in immune cells; linked to inflammation and immune responses.

When THC binds to CB1 receptors, it alters neurotransmitter release, cause to changes in perception, mood, coordination and cognition.
