Concerns explode over new health risks of vaping.
Vapers inhale those same gases and particles into their lungs. Rahman wondered what effects those vapors might have on cells there. One gauge would be to test how long any lung cell damage took to heal.
And his latest data confirm that e-cigarette vapors also make it hard for lung cells to repair damage. Students as young as 12 or 13 are now more likely to vape than to smoke. Many are under the impression that because e-cigs don’t contain tobacco, they pose little risk to health.
Over the past few months, research has turned up evidence that vaping can pose many brand new risks. The vapors mess with immunity, some studies show. “Smoker’s cough” and bloody sores have begun showing up in teen vapers. The hotter a vaped liquid gets, the harsher its effects on human cells.
And a relatively new vaping behavior called “dripping” ups the heat. This threatens to intensify a teen’s risks from those vapors. Some new data even suggest that e-cig vapors may contain cancer causing chemicals.
“There are a lot of potentially harmful substances in e-cigarettes. If you’re a teen with your whole life in front of you, why take that risk?” asks Rob McConnell. He’s an internal medicine specialist at the University of Southern California (USC) in Los Angeles.
