CBD works by interacting with your body’s endocannabinoid system. Humans produce natural cannabinoids and have receptors for them, called CB1 receptors and CB2 receptors. CB1 receptors are present in the body and the brain and bind to THC (delta-9 tetrahydrocannabinol). CB2 receptors are most prevalent in the immune system and affect inflammation and pain. CBD works by directing the body to produce more of its own cannabinoids and restoring balance to the body when it is overworked or stressed.
