1. What Is CBD?

CBD (cannabidiol) is a naturally occurring compound found in the Cannabis sativa plant — one of over 100 identified cannabinoids that interact with the human body's endocannabinoid system. Unlike THC, CBD is non-intoxicating and will not get you high. Hemp-derived CBD containing less than 0.3% THC is federally legal in the United States under the 2018 Farm Bill.

2. How CBD Works — The Endocannabinoid System

The endocannabinoid system (ECS) is one of the most important regulatory systems in the human body, governing pain, inflammation, mood, sleep, appetite, and immune function. It consists of endocannabinoids, receptors (CB1 and CB2), and enzymes.

CBD works primarily by inhibiting the enzyme that breaks down anandamide (the body's natural "bliss molecule"), increasing endocannabinoid tone. It also interacts with serotonin receptors (5-HT1A), TRPV1 pain receptors, and GPR55 receptors.
