A University of Alberta study has found a link between vaping and impairment to lungs and heart function among young adults.

Michael Stickland, professor of pulmonary medicine at the U of A, is leading the study that looks at people in their early 20s who have been using e-cigarettes or vapes for about three years.

“What we saw was these early indications of impaired lung function and potentially exercise intolerance as well, which suggests that their lungs and hearts are not working as well as you’d expect them to,” explained Stickland.

Participants in the study reported no cigarette or marijuana use and went through a traditional lung function test.
