“The cannabinoids in cannabis — cannabidiol (CBD) and tetrahydrocannabinol (THC) — interact with your body by way of naturally-occurring cannabinoid receptors embedded in cell membranes throughout your body. In fact, scientists now believe the endocannabinoid system may represent the most widespread receptor system in your body.1
There are cannabinoid receptors in your brain, lungs, liver, kidneys, immune system and more, and both the therapeutic and psychoactive properties of marijuana occur when a cannabinoid activates a cannabinoid receptor. Your body actually makes its own cannabinoids, similar to those found in marijuana, albeit in much smaller quantities than you get from the plant.
The fact that your body is replete with cannabinoid receptors, key to so many biological functions, is why there’s such enormous medical potential for cannabis. More often than not, medicinal marijuana is made from plants bred to have high CBD and low THC content. While THC has psychoactive activity that can make you feel “stoned,” CBD has no psychoactive properties.
