A new University of Michigan study suggests adolescents who vape cannabis are at greater risk for respiratory symptoms indicative of lung injury than teens who smoke cigarettes or marijuana or vape nicotine.
“I thought that e-cigarettes would be the nicotine product most strongly associated with worrisome respiratory symptoms,” said Carol Boyd, the Deborah J. Oakley Collegiate Professor Emerita at the U-M School of Nursing. “Our data challenges the assumption that smoking cigarettes or vaping nicotine is the most harmful to the lungs. If we control for vaping cannabis in our analyses, we find there is a weaker relationship between e-cigarette or cigarette use and respiratory symptoms when compared to vaping cannabis.”
