The main objectives of the Tobacco Control Unit (UCT) are to understand the factors that influence tobacco consumption and exposure to environmental tobacco smoke and electronic cigarettes, and to develop strategies to prevent and control them. The UCT conducts research and evaluates projects aimed at reducing tobacco consumption and associated morbidity and mortality. It also manages applied intervention projects, such as the Catalan Network of Smoking-Free Hospitals (XCHsF), and healthcare projects, such as the smoking cessation clinic.
