In a nutshell, what’s the difference between CBD and THC?

The difference between CBD and THC is that … they’re not the same molecule! Although they look very similar, they have structural differences that change the way that they interact with our system. They don’t bind with the same receptors, and don’t send the same messages through our bodies. And as a result, what you experience when you take CBD is very different from what you can experience when taking THC.
