Penn Medicine wrote in a Nov. 7, 2017 press release titled "Penn Study Shows Nearly 70 Percent of Cannabidiol Extracts Sold Online Are Mislabeled," available at pennmedicine.org:

“There is interest in CBD as a medicine because there is some evidence that it has medical benefits, but it does not make people feel ‘high’ and there is no indication that CBD, by itself, is abused. Recent research has shown potential therapeutic effects of CBD for young children with rare seizure disorders, and patients in states where cannabis or CBD have been legalized report using it for a variety of health conditions. Business experts estimate that the market for CBD products will grow to more than $2 billion in consumer sales within the next three years. While interest in this area continues to grow, little has been done to ensure regulation and oversight of the sale of products containing CBD.”
