Cannabidiol (CBD) in Pain Reduction for Knee Osteoarthritis

Summary

The purpose of this study is to see if cannabidiol (CBD) orally dissolving tablets (ODTs) can lessen pain, improve function, and improve patient satisfaction in cases of knee osteoarthritis. CBD comes from the cannabis plant and is non-psychoactive (i.e. does not produce a 'high' or altered mental state) as compared to tetrahydrocannabinol (THC), another compound found in cannabis. Researchers are studying different forms of CBD for potential use in treating pain, inflammation, and illnesses.
