Let's face it, we all know any sort of smoking isn't really good for you but the finding that the cells mutated when hit by the smoke is a bit of a concern.
Smoke from e-cigarettes damages DNA and can increase the risk of cancer and heart disease, scientists have warned.
For another part of the experiment, the scientists exposed cultured human cells to large quantities of nicotine in a lab and found similar effects on DNA damage and fix. Participants tended to go longer in the morning before having a vape, they reduced to e-liquids with less nicotine over time and some vaped only zero nicotine e-liquids.
E-cigarette users are possibly putting themselves at risk for developing heart disease, lung and bladder cancers, according to a new report.
'In terms of safety, e-cigarettes are likely far closer to nicotine replacement therapy (NRT). "Some newer vapers still smoked, but they were still cutting down on cigarettes and some only smoked occasionally", Dr Truman says. On the one hand, there are doctors and advocates who insist that vaping is a relatively safe, appealing way for smokers to wean themselves off much more risky tobacco products.
The researchers also exposed cultured human bladder and lung cells to nicotine and found the same effects they have observed in experiments involving mice.
Tests on mice find e-cigs, promoted as a safer alternative to cigarettes contain nicotine which is far from harmless.
Vaping causes DNA mutations which lead to cancer, a new study warns. It also retarded DNA fix functions and proteins in the lungs. 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.
FDA clearance would mark a major milestone in efforts by both the industry and government officials to provide alternative tobacco products to U.S. smokers.
The report also said that the potential dangers and benefits of vaping e-cigarettes may depend on the user's age. 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.
While tobacco smoke contains a host of potentially unsafe chemicals, e-cig liquid consists only of nicotine and relatively harmless solvents.
