My guest this week is Martin Lee, the primary author of the recent book The Essential Guide to CBD (affiliate link), which offers a solid introduction to the many possible benefits of CBD. Martin and I explored how it is that a single substance can have such wide-ranging effects, and got into specific conditions like anxiety, depression, and sleep. If you're new to CBD, or interested to learn more about the science behind its effects, I think you'll find a lot of good information here.
