A study sponsored by National Institutes of Health showed that E-cigarette vapor causes lung cancer and potentially bladder cancer in mice, damaging their DNA and leading researchers at New York University to conclude that vaping is likely “very harmful” to humans as well. The amount of smoke the mice were exposed to was similar to what a human would inhale if they vaped regularly for about three to six years.
“It’s foreseeable that if you smoke e-cigarettes, all kinds of disease comes out” over time, Moon-Shong Tang, the study’s lead researcher, said in an interview. “Long term, some cancer will come out, probably. E-cigarettes are bad news.”
As e-cigarettes or vaping products are still fairly new, only time will tell as to how carcinogenic vaping nicotine actually is, yet the study is the first to link vaping nicotine to cancer.
Researchers at NYU also found that e-cigarette vapor caused DNA damage in the lungs and bladder and “inhibits DNA repair in lung tissues.” Out of 40 mice exposed to e-cigarette vapor with nicotine over 54 weeks, 22.5% developed lung cancer and 57.5% developed precancerous lesions on the bladder.
None of the 20 mice exposed to e-cigarette smoke without nicotine developed cancer over the four years they studied the mice, researchers said.
That’s “statistically very significant,” said Tang, who’s a professor at the NYU School of Medicine.
A study released in February by the University of Southern California, found that e-cigarettes cause the same molecular changes in oral tissue found in smokers or regular cigarettes.
