Cannabis Use and Mental Health Effects

Created by Meredith Fisher-Corn, MD and Stephen B. Corn, MD

Editors' Note: Medical marijuana has become an important area of study in healthcare. Doctors and healthcare professionals must understand the medical, legal, and social issues to best respond to their patients' questions and attend to their needs. This content area is not intended to encourage or dissuade the use of medical marijuana, but has been created to provide a balanced portrayal of the research in this area.

This course is comprised of two parts. The first part reviews the literature evaluating the mental health effects of cannabis use, while the second part addresses cannabis use disorder.
