Developed for health professionals and updated in 2020, the Medicinal Cannabis and Chronic Pain online training presents current information and clinical practice guidelines on the use of medicinal cannabis for the treatment of chronic pain.

The first module is a basic primer on the mechanism of action of medicinal cannabis, its medical uses, and Washington State law. The second module focuses on the best clinical practices associated with the recommendation of medicinal cannabis. This training will also provide tools that may be useful to health care providers in their discussion with patients about the use of medicinal cannabis in the treatment of chronic pain. CME available!
