Study: E-cigarettes Cause Lung Cancer in Mice

Do e-cigarettes cause lung cancer? The answer appears to be yes in a study by New York University. The first of its kind to make the link.

Inhaling e-cigarette vapor, often marketed as a safe alternative to smoking, just got some bad news. Researchers at New York University published a study that found that a link between inhaling e-cigarette vapor and lung cancer in mice. Additional evidence pointed toward a potential increase in bladder cancer cases, as well.

E-Cigarettes Cause Lung Cancer Data: “Statistically Significant”

In the NYU study, researchers found that e-cigarette vapor caused DNA damage in the lungs and bladder and “inhibits DNA repair in lung tissues.” 
Of the 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. Not one of the 20 mice exposed to e-cigarette smoke without nicotine developed cancer over the four years they studied the mice, researchers said. It appears that the combination of nicotine and e-cigarette vapor was the signifiant data point. They did not study the effects of THC-based vape pens.

That’s “statistically very significant,” said Tang, who’s a professor at the NYU School of Medicine.

When Will We Know More?

We won’t know exactly how carcinogenic e-cigarette vapor is to humans for a while. But this is a concerning study. E-cigarette and vape pen use is still a relatively phenomenon in society. But all this raises many questions. We do know that smoking traditional cigarettes are bad for you. But this study sheds some concerning light on how healthy of an alternative vape pens are.

And this study comes at a time when vape pens and e-cigarettes are in the news. Additionally, there’s a huge teen vaping epidemic that has lead some states to ban flavored e-cigarettes. 29 people have been killed and over 1,300 have been injured in the epidemic across 48 states. 

Most of the VAPI (vaping associated pulmonary injury) sufferers were using THC-based vape pens. There have been reports that some were using nicotine-based pens. And the main issue is that the CDC and FDA still haven’t pinpointed the cause of these new VAPI cases. Leaving many consumers in the dark.

And now a number of governors and legislators have enacted state vape pen bans.

And now even more questions are surrounding the industry. While black market vapes have always been a question, a new problem has arisen. Kushy Punch, a legal vape pen brand was alleged to have an illegal facility making illicit products. Additionally, Dank Vapes, another popular brand has been coming under fire amid the epidemic.

Most were thinking they were using a product that was healthier for them. But now, no one can be so sure.
