Smoking is the primary avoidable cause of premature death and morbidity in our country. According to data from the WHO, tobacco costs more than 5 million lives per year, a figure that is assumed to continue increasing and will be 10 million by the year 2030. As health professionals we are obliged to be actively involved in this serious health problem, by correctly identifying, diagnosing and treating all smokers to help them in the process of giving up and help them achieve total abstinence. There is scientific evidence that smoking is the direct cause and reason for the worsening of many respiratory diseases, which due to their nature are basically the responsibility of the pneumologist, who officially, according to the Health Service Administration, is the specialist and expert in this area. The Smoking and Health Area of SEPAR was started in 1995. Its primary objectives were to increase the awareness of the smoking problem among the members of our Scientific Society, improve their scientific knowledge of this diseases, to help in diagnostic and treatment interventions in smokers, and lastly, to promote interventions for the prevention and treatment of smoking by the health and political Administrations. Nowadays it is one of the most dynamic areas of SEPAR and has more than 400 members. There are many unresolved challenges in our area, but the fundamental one which continues to occupy a particular place for the Administration, for our patients, for other health professionals of other specialties and scientific societies, and for all SEPAR professionals, is a key aspect of which there is no doubt: to defend the health and well-being of our population against the main cause of avoidable disease and death, tobacco.
