Cannabis has been used by humans for thousands of years. Proven to be safe and medically effective for many conditions, it is emerging from the stigma of being illegal over the last century. Now that it's legal in Canada, the number of people seeking medically specific cannabis products is growing rapidly. Medical and recreational cannabis are two very distinct streams, however, and there are major differences between the two: from types of product to points of access, applications, dosing - even in the intent to use. Patients are specifically looking for relief of symptoms without impairment - the high that recreational users seek. Many Canadians have been self-medicating for years, but that is not the safest, most reliable, or most effective way of using cannabis as medicine. Health Canada continues to govern medical cannabis, keeping its use, access, and legislation distinct from the recreational stream. This book brings clarity for both patients and health care providers (who receive little to no formal education about medical cannabis) and is a comprehensive guide to this re-emerging field of medicine. Clarifies the differences between medical and recreational cannabis. Covers the history, research, and health benefits of cannabis and discusses its application to some 40 specific diseases and symptoms. Explains how to access and use cannabis for medical purposes, as well as the laws that apply specifically to medical cannabis. Features a glossary of key terms, especially useful for patients; Canadian-specific resources; and an extensive reference section citing source material and research from around the world that is guiding medical practice. "Mark, your discussion on medical cannabis is thoughtful, measured and easy to understand. Well done." - C. Dale Mercer, General Surgeon, Professor Emeritus, Queen's University
