Clinical Trial Summary

To determine vaping behaviors and respiratory function in obese and nonobese youth e-cigarette users.

Description:

The investigators hypothesize that obese youth e-cigarette users will have increased e-cigarette use that will worsen respiratory function. The approach will involve a clinical trial where vaping behaviors (using puff topography) and respiratory function (spirometry, plethysmography, and diffusion capacity) will be assessed while participants vape with their own e-cigarette and, on a separate visit, with the VUSE e-cigarette.
