CHICAGO (Reuters) – Using e-cigarettes significantly increases the risk of developing chronic lung conditions such as asthma or emphysema, U.S. researchers said on Monday.

The study, published in the American Journal of Preventive Medicine, is among the first to show the potential long-term harms of using e-cigarettes, which are often promoted as a safer alternative to tobacco and a means of helping smokers quit.

It found that e-cigarettes increased the risk of lung disease by a third compared with those who never smoked or vaped. And the risk was even higher among adults who used both e-cigarettes and smoked tobacco.

The research comes as the United States faces a youth vaping crisis. According to the U.S. Centers For Disease Control and Prevention (CDC), more than 27.5% of high school students in the United States use e-cigarettes, up from 20.7% in 2018.

“E-cigarettes are promoted as harmless and they’re not,” Stanton Glantz, director of the University of California San Francisco Center for Tobacco Control Research and Education, said in a phone interview. Read more
