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.

Eligibility criteria

Qualifiers

Written informed consent must be directly obtained from legally competent participants before any study-related assessment is performed.
