26 Aug 2019 --- A growing body of pre-clinical and clinical evidence suggests that cannabidiol (CBD) oils may hold promise for treating conditions such as chronic pain and opioid addiction, according to a review of the latest research on the subject, to be published in September in Mayo Clinic Proceedings. However, the authors note that more research involving humans is needed before health care providers can definitively classify CBD as helpful and safe. With their latest findings, the researchers are advising physicians to expand their knowledge on the cannabis extract to best advise their patients.
