Vaping Could Cause Cancer and Heart Disease, New Study Suggests

"We know from talking to teachers that in schools where smoking rates are high in the local community, cigarettes are sold to younger children by teen smokers in order to maintain their own smoking".

"Based on these results, we propose that [e-cigarette vapour] is carcinogenic and that E-cig smokers have a higher risk than nonsmokers to develop lung and bladder cancer and heart diseases", reads the research.

The US team led by Dr Moon-shong Tang, from New York University School of Medicine, warn that "vapers" may be increasing their risk of life-threatening conditions. "It is not surprising of course that this damaged the cells, but this has no relationship to any effects of e-cigarettes on people who use them", he said.

While some researchers said the work was important, others all but dismissed it as irrelevant to humans.

Vaping could cause cancer and heart disease, according to a new study. According to the chemists, the damage caused by vaping increased as a person took more puffs of an e-cigarette.

About one in 20 people in the United Kingdom has adopted a vaping habit as a markedly safer alternative to smoking tobacco. "It would also provide clarity around the greatly reduced risk associated with vaping compared to smoking which would encourage more people to make the switch".

Recent studies have shown that e-cigarette smokers have 97% less of a lung carcinogen known as NNAL in their bodies than tobacco smokers.

The news comes after researchers tested the effects of e-cigarettes on mice, and human lung and bladder cells. A typical e-cigarette is filled with a variety of chemicals, including propylene glycol, glycerine, nicotine, and flavorings such as menthol. This amounted to what Hajek called "extremely large doses of nicotine".

Researchers found that nicotine inhaled from e-cigarettes can be converted into chemicals that damage DNA. Their organs were likewise less able to fix DNA.

The lung and bladder cells that were exposed to nicotine turned into tumor tissue more easily. They found remarkable differences in levels of potentially toxic chemicals among e-cigarette users and smokers.

This breakthrough follows on from a report published a week earlier (23 January), in which it was suggested that e-cigarettes can help adults to quit smoking conventional cigarettes.

They pointed out that e-cigarettes were rapidly gaining popularity, especially among young people who regard them as harmless.

This latest study is not, by itself, conclusive.

In 2016, the FDA finalized a rule extending its regulatory authority to all tobacco products, including e-cigarettes, cigars, as well as hookah and pipe tobacco, as part of its goal to improve public health.
