Brief Summary

Although electronic cigarettes (e-cigs) are now widely used, very little information exists regarding the effect of electronic cigarette use (vaping) on the respiratory system. The aim of this study is to evaluate the acute effect of one e-cig vaping session (30 puffs 30 seconds apart) on cough reflex sensitivity in healthy adult nonsmokers.

Outcome Measures

Primary Outcomes (1)

  • Change in Cough Reflex Sensitivity (Log C5)

    Measurement of cough reflex sensitivity to capsaicin (C5) performed 15 minutes and 24 hours after electronic cigarette use session. Changes in cough reflex sensitivity 15 minutes after e-cig use compared to baseline will be assessed. In addition, cough reflex sensitivity 24 hours after e-cig exposure will also be measured, so that duration of any changes noted after 15 minutes can be assessed. Increase in C5 means decrease in cough reflex sensitivity. Capsaicin cough challenge involves subjects breathing in incremental doubling concentrations of aerosolized capsaicin, 1 minute apart, until the concentration of capsaicin (micromolar) inducing 5 or more coughs (C5) is reached.

    Baseline, 15 minutes, and 24 hours post-exposure to e-cig.
