Multiple Sclerosis Clinical Trial

Mechanisms of Cannabidiol in Persons With MS: the Role of Sleep and Pain Phenotype

Summary

The purpose of this research study is to compare the effects of cannabidiol (CBD), tetrahydrocannabinol (THC), or both, on sleep and pain in persons with multiple sclerosis (MS). Little is known about how CBD and/or THC may help sleep, reduce pain, or perhaps even treat pain through better sleep.
