About this trial

This is a longitudinal study of the long-term health impact of cannabis smoking on the lungs. Participants will be followed over a period of 3 years, and impacts of cannabis 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.
