Where in the body are the CB1 and CB2 receptors, how they transmit signals, and how the action of CBD differs from THC at the receptor level. A guide based on research.

The Realm of Caring registry analyzed by Johns Hopkins: quality of life, fewer prescription medications, and less frequent emergency room visits. The numbers, methodology, and limits of conclusions.

PET imaging measured the return of CB1 receptors after 26 days of abstinence from cannabis. It says nothing about two days and nothing about cannabidiol.
