Grant: Project Grant

In recent years there has been rapid growth of electronic cigarette (E-CIG) use among teens and young adults. Despite their growing popularity and evolving technology towards a stronger vaping stimulus, our understanding of how these devices affect lung health is extremely limited. Our preliminary results show that chronic E-CIG use among young noncigarette smokers is associated with breathlessness, exercise intolerance and impaired lung blood flow. Using advanced techniques and interventional trials, the aim of this grant is to examine pulmonary blood flow, ventilation/perfusion matching and exercise tolerance in nonsmoking teens & young adult E-CIG users to better understand the early cardiopulmonary consequences of E-CIG use.
