About this trial
This is a longitudinal study of the long-term health impact of e-cigarette smoking on the lungs. Participants will be followed over a period of 5 years, and impacts of e-cigarette smoking on the lungs will be measured with magnetic resonance imaging (MRI) using hyperpolarized xenon-129 gas, pulmonary function tests, exercise capacity, computed tomography images and questionnaires.
