Warning: E-Cigarettes Can Also Damage Your Lung

  • 12

In recent years, e-cigarettes have become very popular among Americans, especially among young Americans. E-cigarettes are said to be far less harmful than cigarettes and can help you quit smoking for good. But are e-cigarettes really safe?



The latest study in mice raises some health concerns about the use of electronic cigarettes.


About the study


In the study, the researchers split the mice into four groups:

—The first exposed to cigarette smoke for four months

—The second exposed to e-cigarette vapors with solvents and nicotine for four months

—The third exposed to e-cigarette vapors with solvents but no nicotine for four months

—The last exposed to clean air for four months



As expected, mice chronically exposed to cigarette smoke or e-cigarette vapors with solvents and nicotine had severely damaged lungs and excessive inflammation. This finding suggests that human smokers are more likely to develop emphysema, a lung condition that causes shortness of breath.


Unexpectedly, mice chronically exposed to e-cigarette vapors, without any nicotine, also had damaged lungs. In this case, though the researchers did not observe inflammation, they found evidence of abnormal buildup of lipids (fats) in the lungs and macrophages (large white cells to "eat" particles bad for your health).



The abnormal fats in mice's lungs disrupted both normal lung structure and function. When the mice were exposed to influenza virus, the abnormal macrophages also responded poorly to the infection.


"In summary, our experimental findings reveal that, independent of nicotine, chronic inhalation e-cigarette vapors disrupts normal murine lung function and reduces the ability of resident immune cells to respond to infection, increasing the susceptibility to diseases such as influenza," said corresponding author Dr. Farrah Kheradmand.



Concerns about e-cigarettes


E-cigarettes are the most commonly used tobacco products in the adolescent population in the United States. "More than 3 million high school age adolescents as well as about 10 million adults in the U.S. are active users," said Kheradmand.


Although e-cigarettes are often advertised as a less dangerous alternative to cigarettes, they may still have health risks. You should really think twice before using e-cigarettes.

I also want to give up that but I get addicted.
As the level of nicotine in your blood drops, the level of anxiety rises and you would feel so eager to have one more. The key to a successful cessation is to manage your anxiety level.
E cigarettes are only a game the producers play with smokers. They are packed for profits.
I know someone tells you its so hard to give up smoking, but Im here to give you a real example. My uncle gave up smoking the day he was told by the doctor continue smoking would kill him. He never touched cigarettes since then.  Its not about hard, its about your will.
Cigarettes are evil? Why not check how much tax it provides each year from Yes, Prime Minister Season 1 Episode 3.
Tax one thing and pension saved another. Smokers die soon after all.
Medical techs are so developed now. They'll spend more money on treatments for COPD. heart disease, tumors, et al. More than pension.
Medical insurance comes from taxes which are contributed by the smokers themselves. And they promotes to medical development and related jobs. Just from the economic angle smokers can do some good things.
Alright so the money you pay for ecigarettes are only to prove you are a dumb?
Spending money on cigarettes no matter e- or no e- already proves you're a dumb.
Let those who are without sin cast the first stone.  Calling people dumb does nothing.
Educating the masses is the a answer.
Do they use e-cigarettes just because they are fashionable? I have some female friends who smoke only for the "cool" feeling rather than they fancy it.
Pretty many articles criticizing e-cigarettes recently huh? But comparing with Nicotine, tar in the cigarettes causes most harm. There is no or little tar in e-cigarettes.
These articles merely mention tar. I think the writers work for cigarettes producers.
I don't smoke. Why not just break an e-cigarette up, see what's in there?

That's your value, rats.
News last year, reported by CNN: Juul was extremely popular among American adolescents and was required to provide all the research and sale data by FDA because of "public health effects." Juul's spokesman claimed to cooperate with FDA's investigation and sold their products only to adults beyond 21.
