Tuesday, August 14, 2018 (HealthDay News)- Electronic Cigarette Promoted as a safer alternative smokingHowever, the vapors they produce can be as harmful to lung tissue as regular tobacco, British researchers report.

presence or absence nicotine, E-cigarette Steam increases inflammation and disables the cells that protect lung tissue, human tissue tests reveal.Damage to these cells makes them vulnerable to dust, bacteria, and allergens that can lead to incurability. Chronic obstructive pulmonary disease (((COPD), Researchers say.

“There was a lot of support for people to use Electronic Cigarette Recognized for the safety of e-, instead of traditional tobaccocigarette The process. ” Principal Investigator Dr. David Ticket said in a podcast. He is a professor of respiratory medicine at the University of Birmingham, England.

“There is an agenda to describe e-cigarettes as safe,” said Thickett. But since it’s only been 10 years since e-cigarettes were on the market, the effects of long-term vaporization are unknown, he said.

E-cigarettes probably have fewer poses cancer It’s unclear if it’s as safe as the manufacturer claims, but it’s more risky than regular cigarettes. However, it seems that the vaping process itself can damage immune system cells-at least in the lab, Thickett said.

“We need to have cautious skepticism [e-cigarettes] It’s as safe as we are guided to believe. ”

“If you develop when you smoke for 20 or 30 years COPD, That’s what we need to know, “he added.

Using a device that mimics vaping, Thickett’s team has eight nonsmoker For liquids of various types of electronic cigarettes.None of the participants have ever suffered asthma also COPD..

One-third of the cells were exposed to plain e-cigarette liquid. One-third with and without the strength of artificial steam nicotineAnd one-third was not exposed to anything for 24 hours.

The results showed that the vapor was far more harmful to the cells than the e-cigarette liquid itself-and the more lung cells were exposed to it, the more damaged they were. Researchers have found that vapors containing nicotine have made the effect more pronounced.

Exposure to the liquid itself increased cell death and the production of oxygen-free radicals by a factor of 50, the researchers added. Free radicals are reactive chemicals that can damage cells.

In addition, cells exposed to vapor-laden liquids were unable to repel bacteria. However, antioxidant treatment helped restore that ability and reduce other damage caused by e-cigarette liquids, Thickett’s team found.

Dr. David Hill is a member of the Board of Directors of the American Lung Association, which reviewed the findings.

E-cigarettes may be safer than traditional ones, Hill said, but “just because they’re less harmful doesn’t mean they’re safer.”

He has a vaping lung.. However, this study suggests that long-term vaporization can lead to lung damage.

“Be careful when promoting these as safe,” said Hill, director of clinical research at Waterbury Palmonary Associates, Connecticut. “Do you encourage patients to use these or do they need to be sold as a safe alternative? smoking?? Absolutely not. ”

The report was published online in the journal on August 13th. rib cage..
