Physicians are the “key experts” in the medical marijuana debate. The issue is ultimately based on the medical value and risks of marijuana. Physicians, with their training and clinical experience, should (at least in theory) have the best knowledge of marijuana’s medical value and risks. Dr David Bearman is one of the most knowledgeable physicians in California regarding the medical use of cannabis.

Dr. Bearman has made hundreds of presentations to professional and lay audiences on medical marijuana, drug abuse treatment and prevention and the origins of American drug policy. He is a dynamic, entertaining and informative speaker. His presentations are illustrated by well-organized, Power Point slide shows. He is available to talk to medical groups, colleges, civic and parent organizations. He has made presentations on these topics to the American Public Health Association, the American College Health Association, Patients Out of Time, NORML, the American Academy of Anti-aging Medicine, the Pediatric Department of the Balboa Naval Hospital, Grand Rounds at San Diego Hospital, and the Department of Community Medicine at the University of California, San Diego.
