A new study is highlighting the dangers of e-cigarettes and vaping.

The devices have been shown to damage cells that protect your airway.

Dr. Farbia Rezaee said researchers created a breathing simulator for the study and tested different devices and flavors to see how each one would affect cells in the airway.

No matter what the device – or the flavors – they all caused harm.

The combination of flavor and nicotine were the worst, Rezaee said. Researchers learned that the use of e-cigarettes or vapes can put a person at a greater risk for viral infections.

“Why is it important? Because if the integrity of the airway barrier is disrupted, everything can get in, like all of the viruses can get in, or other pollutions or allergens can get in,” Dr. Rezaee said.

More research needs to be done on the long-term effects. In the meantime, she strongly encourages everyone who uses e-cigarettes or vapes to quit.
