Why is it so difficult to quit smoking? Often the main obstacle is the fear of failing. The situation is no different for health professionals, especially doctors. They too often stop because of their fear of failure, or get discouraged, thinking they might not have the skills to help people quit smoking. Yet encourage and support patients to stop smoking is one of the primary tasks of the doctor, as you can well understand the harmful consequences of smoking on health. Moreover, the treatment of smoking is not complicated, if you have some basic skills: pharmacologic treatment, patient-doctor communication and motivational interviewing. This book comes from daily practice. The author explains in a very direct way the art of "tobaccology", with simulated examples and useful tricks. Current and relevant data on epidemiology, neurobiology of addiction, risks, comorbidity and treatment are then provided.
