"Without a doubt, cigarettes and e-cigarettes are unhealthy and not good for lungs. However, vaping marijuana appears even worse," said Carol Boyd, who authored the study and is co-director of the Center for the Study of Drugs, Alcohol, Smoking & Health at the University of Michigan in Ann Arbor. The study, “Cannabis, Vaping, and Respiratory Symptoms in a Probability Sample of U.S. Youth,” was published in the Journal of Adolescent Health

"Since many teens who vape nicotine, also vape cannabis, I recommend parents treat all vaping as a risky behavior (just like alcohol or drug use)," Boyd added.  

For the study, researchers looked at the results from the Population Assessment of Tobacco and Health study, which surveyed 15,000 people between ages 12 and 17. They asked the teens about vaping, cigarette use and their negative respiratory symptoms. Read more.
