Author Bio

The COVID epidemic has accelerated research of the immune system’s integrated response to viral diseases. This 30-minute video sponsored by the American Osteopathic Association discusses cannabinoids’ impact on optimal immune function. It is presented by physician author, Jeffrey S. Block, MD – founder and principal partner of an independent professional consultancy providing client organizations with advanced scientific guidance. Dr. Block’s industry-wide expertise provides insight by translating the evolving science’s objective evidence-based data into clinical applications.

About the Author

Jeffrey Sherwood Block, M.D. . is a Board-certified physician anesthesiologist and adjunct Professor at the University of Miami Miller School of Medicine. Additionally, he is a highly awarded horticulturist and certified Master Gardener educator with the University of Florida’s UF/IFAS Extension Program. Dr. Block’s textbook chapter “Endocannabinoid Receptors and Medical Cannabis” (Advanced Therapeutics in Pain Medicine – CRC Press 2020) is a sentinel work on integrated pain management. Block served as the Florida Medical Association’s “Designated Expert on Botanical Medicines” authoring mandated physician education; and in 2014 was appointed by Florida’s Surgeon General to determine the rules for Florida’s first cannabis law. His consultancy’s demonstrated insight and responsible leadership are valued by both allied professionals and new industries seeking knowledge of future uses for Cannabinoid medicines.
