Listen now (53 min) | This week I am pleased to welcome Dr. William Courtney back to the program along with his wife Kristen Courtney for a second part to their interview. Dr. Courtney's area of special interest is in the dietary uses of cannabis to which he considers as a conditionally essential nutrient in the diet of individuals of 40 years and older, and Kristen brings a decade of personal experience and research to the area of whole plant use for prevention and treatment.
