The results of a clinical report Cannabidiol in Anxiety and Sleep: A Large Case Series in The Permanente Journal published in January 2019 report that there is existing scientific evidence that illustrates CBD helps improve sleep and/or anxiety in a clinical population. This is a large retrospective clinical case series of adult patients with documented anxiety or sleep disorder diagnosis. Follow up evaluation was done monthly with CBD dose between 25mg to 75mg daily. Anxiety and sleep improved (79.2% and 66.7%, respectively) for most patients, and these improvements were sustained over time. The sustained CBD effect were shown to be maintained better with patients with anxiety than for sleep from the results of subsequent monthly clinical evaluations.
