Vaping damages DNA, could improve most cancers & coronary heart illness danger - examine

Vaping and e-cigarettes have gained considerable popularity as a less harmful alternative to traditional cigarettes

"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. "It's certainly concerning, and certainly gives pause if one were to say e-cigarettes were safe and could be used by all people without consequences". "But the trend was still there - something in the e-cigarettes was definitely causing damage to the DNA".

The researchers also exposed cultured human bladder and lung cells to nicotine and found the same effects they have observed in experiments involving mice. "I never expected the DNA damage from e-cigarettes to be equal to tobacco cigarettes", Kadimisetty said. By 2015, 16 per cent of American high school students said they used e-cigarettes, making it the most popular nicotine product among kids. However, the researchers also cited another study that found 97 percent less of a key biomarker related to genetic damage in the urine of vaper smokers compared with smokers. On the other, there are those who say that vaping's risks are unclear and might still rival that of traditional smoking.

At the end of the three months, Tang found DNA damage in the hearts, lungs and bladders of mice exposed to the vapours that was not evident in a control group of animals that breathed filtered air.

The problem comes when trying to gauge how much of an added risk e-cigarettes pose to your health.

During the tests, some mice were exposed to smokes emanating from e-cigarettes.

Knicks Seek To Dump Joakim Noah After Heated Clash With Coach
Waive :?The Knicks could choose to waive Noah, though they'd likely attempt to negotiate a buyout before exploring this option. The officially stated reason for Noah's absence from the Knicks' last two games was "personal reasons".

The study was published January 29 in the Proceedings of the National Academy of Sciences.

Tobacco smoke contains over 70 chemicals that are known to cause cancer, while e-cigarette vapor contains far fewer toxic chemicals. The study is released at the same time as a report by The National Academies of Science, Engineering and Medicine, which declares that "e-cigarettes are likely to be far less harmful than combustible tobacco cigarettes".

The news may come as a shock for many users of e-cigarettes, as vaping has grown in popularity due to its percieved health advantages over smoking tobacco.

Furthermore, while the use of e-cigarettes can help adults to stop smoking conventional cigarettes, the study found substantial evidence that e-cigarette use results in symptoms of dependence on e-cigarettes.
