Study Warns E-cigarettes More Harmful Than Previously Thought

Study Warns E-cigarettes More Harmful Than Previously Thought

He said: "In terms of cancer causing molecules in cigarette smoke, as opposed to cigarette vapour, there are certainly reduced numbers of carcinogens. They are safer in terms of cancer risk - but if you vape for 20 or 30 years, it can cause chronic obstructive pulmonary disease", Thickett was quoted saying, according to a report in The Sun.

However the US Surgeon General has warned that e-cigarettes leave young people at risk of nicotine addiction, brain development problems and mood disorders, while the World Health Organisation has said it is concerned that heating e-fluid can lead to the 'formation of toxicants'. Britain's public health authorities are pushing smokers to switch to it as a safer choice; experts in the U.S. have warned that electronic cigarettes increase the risk of nicotine addiction among young people, while the World Health Organization has said uneasily that warming up electronic cigarettes can lead to the formation of toxic substances. A small experimental study, led by Professor David Thickett, at the University of Birmingham, showed that in only over 48 hours the vapour from e-cigarette caused inflammation and impaired activity of alveolar macrophages - cells that remove potentially damaging dust particles, bacteria and allergens.

While vaping has regularly been touted as a safer alternative to cigarette smoking, emerging research is starting to paint a different picture. But since e-cigarettes have been around for only a decade, the effects of long-term vaping aren't known, he noted.

Martin Dockrell, who is the lead for tobacco control at Public Health England, said: "E-cigarettes are not 100% risk-free but they are clearly much less harmful than smoking".

The vaping process damaged the vital immune system cells, they concluded.

Taliban Storms Key Afghan City of Ghazni
This has been the worst Taliban offensive on a provincial capital since the brief occupation of the western city of Farah in May. Sharif Yaftali, army chief of staff, says all strategic and government offices in Ghazni are still under government control.

They set up a machine that replicated the effect of vaping and studied what happened to the samples of tissue. Treatment with an antioxidant, however, restored that ability and helped reduce other damage caused by e-cigarette fluid, Thickett's team found. Well, now they say switching from warm smoky air to cold apple-flavoured air isn't all that unbelievable a change to make, as huffing vapourised chemical compounds gives your lungs an entirely new collection of shit to deal with.

Public Health England, however, considers vaping safer than traditional cigarettes.

British scientists have expressed "great reservations about the widespread view that electronic cigarettes are safe".

E-cigarettes work by heating a liquid, and creating a vapour that usually contains nicotine.
