Pulmonary health, assessed with self-reported measures, clinical evaluations and the Leicester Cough Questionnaire, improved in participants who stopped smoking compared to their own baseline. Moreover, participants in this group [nicotine e-cigarettes] showed the lowest level of exhaled carbon monoxide, and the lowest level of dependence compared to the nicotine-free e-cigarette and control conditions. | Pulmonary health, assessed with self-reported measures, clinical evaluations and the Leicester Cough Questionnaire, improved in participants who stopped smoking compared to their own baseline.

*The statistical associations between e-cigarette use and respiratory disease are driven by e-cigarette users who are also current or former smokers of combustible tobacco. | |||
*A striking feature of the data is that almost all e-cigarette users were either current or former smokers of combustible tobacco. | |||
*Among respondents who had never smoked combustible tobacco, we find no evidence that current or former e-cigarette use is associated with respiratory disease. | |||
