Electronic cigarettes linked to wheezing in adults, new study finds

People who vaped were nearly twice as likely to experience wheezing compared to people who didn't use tobacco products, according to a new study. The findings are consistent with past research that shows emissions from e-cig aerosols and flavorings damage lung cells by generating harmful free radicals and inflammation in lung tissue. Study authors say the take-home message is that electronic cigarettes are not safe when it comes to lung health.
