Cardiopulmonary Consequences of Vaping in Adolescents: A Scientific Statement From the American Heart Association

Most new users of e-cigarette products have never smoked traditional cigarettes; therefore, understanding the respiratory and cardiovascular consequences of e-cigarette use has become of increasing interest to the research community. Most studies have been performed on adult e-cigarette users. Still, most of these study participants are either former traditional smokers or smokers who have used e-cigarettes to switch from traditional smoking. Therefore, this population's respiratory and cardiovascular consequences are not attributable to e-cigarette use alone.
