A huge, landmark research paper this month analysed 800 previous studies into the health effects of e-cigarettes - and found that they are far less unsafe than cigarettes. "The results may take years to come in because cancer is such a slow process", he told The Guardian.
Because of this and other factors, some researchers have dismissed the findings.
During the tests, some mice were exposed to smokes emanating from e-cigarettes.
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. 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. Recent studies have shown that e-cig users have 97 per cent less of a lung cancer-causing component known as NNAL in their bodies than tobacco smokers.
HMD Global launches Nokia 3310 4G in China
There's no official word yet on the pricing and availability of the phone in China and other global markets including India . After plenty of leaks and rumors, HMD Global has finally launched the 4G avatar of its nostalgia-inducing Nokia 3310 .
The scientists did note that "many of these e-cig smokers [who] have taken up the e-cig smoking habit are not necessarily doing it for the goal of quitting TS (tobacco smoking), rather, it is because they are assuming that e-cig smoking is safe" in their writing. Perhaps unsurprisingly though, it's the nicotine that causes the damage, while solvents themselves do not appear to cause DNA damage at all. A Californian study using self-reported measures has indicated that teenagers who use e-cigarettes are twice as likely to develop a persistent cough, wheeze, or bronchitis than those who have never used these devices. This amounted to what Hajek called "extremely large doses of nicotine".
They found that in comparison to filtered air, e-cigarette vapour damages DNA and also prevents the genetic code from repairing itself. Natural DNA fix mechanisms were also suppressed in the mice exposed to the smoke.
However, not all animal research produces similar results in humans.
The study's authors recommend that further long-term studies are needed.
Shopian youth injured in Army firing succumbs
The Army has maintaining that its personnel had fired after a junior officer fell unconscious following the mob attack. On naming the Major in the FIR, he said , "I think they have prematurely put the name of an individual".
The report found a decline in use of cigarettes and electronic cigarettes among those ages 18 to 20. But the evidence is pointing towards them being far less harmful than tobacco.
"Up to two-thirds of long term smokers will die due to their addiction, but e-cigarettes don't contain tobacco".
"Research in people has shown that those who make a complete switch from smoking tobacco to e-cigarettes can significantly reduce their exposure to key harmful chemicals in tobacco smoke".
