Study Background

Cancer and its treatment can negatively affect your life in a variety of ways, and patients often report problems with pain, mood disturbance, and sleep, as well as stress and mental health challenges that worsen quality of life. 

In this research study, we want to examine the effects of cannabidiol (CBD) on sleep quality, pain, mood disturbance, cognitive functioning, and quality of life in cancer patients. Our goal is to examine the effectiveness and safety of CBD for cancer patients.
