All of the 60-plus cannabinoids unique to the plant genus Cannabis interact with our bodies thanks to a network of neurons called the Endocannabinoid system. The Endocannabinoid system runs throughout your body and it’s loaded with receptors that bind to the cannabinoids you introduce to your bloodstream when you consume Cannabis or hemp. It’s the chemical interactions of those bonds that create a wide and largely unknown series of responses in your body.
Without distorting the science too much, you could say that human beings are “hard-wired” for cannabis. The endocannabinoid system runs deep and touches all of the major systems of the body. And that’s why cannabis can do so many things for us, from altering and regulating moods to stimulating appetites and reducing pain. Even though cannabidiol (CBD) has no toxicity for humans—meaning, it doesn’t make you intoxicated (i.e. high)—it is highly reactive with the Endocannabinoid system. To put things as simply as possible, CBD makes things happen. When it binds to the Endocannabinoid system’s receptors, it stimulates all kinds of changes in the body. Most of those changes are incredibly beneficial, and researchers keep uncovering real and potential medical uses for them.
