As the authors admit, though, tobacco smoke is chock full of other nasty chemicals that can cause cancer along with other health problems, such as emphysema. Karteek Kadimisetty, a chemist at the university, said, "From the results of our study, we can conclude that e-cigarettes have as much potential to cause DNA damage as unfiltered regular cigarettes".
The New York University School of Medicine team, led by Dr Moon-shong Tang, pointed out e-cigs were rapidly gaining popularity, especially among young people who regard them as harmless.
While tobacco smoke contains a host of potentially risky chemicals, e-cigarette vapour consists only of nicotine and some relatively harmless organic solvents. Perhaps unsurprisingly though, it's the nicotine that causes the damage, while solvents themselves do not appear to cause DNA damage at all.
Long-time 49ers QB Alex Smith has a new team
Signs have pointed for some time that the Chiefs would trade Smith, their starting quarterback since he was acquired in 2013. A three-time Pro Bowler, Smith was on the Browns' radar as their starter for next season, and they tried to make a deal.
The researchers also exposed cultured human bladder and lung cells to nicotine and found the same effects they have observed in experiments involving mice.
"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. That is similar to the level seen in people on nicotine-replacement therapy. Research like this is important, but this lab study only looked at the effects of e-cigarette smoke on cells and on mice, which means it's not possible to draw any conclusions from this about how e-cigarettes might affect people in real life.
A slew of studies examining the long-term health consequences of vaping have been conducted, but the conclusions have been mixed.
Suns planning to pursue Pistons' Avery Bradley in free agency
In a new environment on a playoff team, Bradley could rediscover his old form and give a contender a valuable perimeter defender. For a guy that has missed at least five games in six straight seasons now, durability concerns were easy to see coming.
Now there were 18 million e-cigarette smokers in the USA and 16% of high school students used the devices, said the researchers.
A comprehensive review of the scientific literature, released earlier this month by the US National Academies of Science, found that vaping is likely less harmful than cigarettes, but may lead to addiction in young people. They found remarkable differences in levels of potentially toxic chemicals among e-cigarette users and smokers. Vaping May help adults quit smoking but may entice young people to smoke conventional tobacco. The study estimates that the risk of one cigarette per day is greater than previously thought and equals about half the risk of smoking 20 cigarettes a day.
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.
