'Safe' vaping could cause lung damage

"But we should have a cautious scepticism they are as safe as we are being led to believe".

"Any smoker considering e-cigarettes should switch completely without delay", he urged.
"The study's lead author, Professor David Thickett, said, "[E-cigarettes] are safer in terms of cancer risk, but if you vape for 20 or 30 years and this can cause COPD [chronic obstructive pulmonary disease], then that's something we need to know about".

In an accompanying podcast, Professor Thickett said the tobacco giants, who have bought up numerous e-cigarette companies, have an agenda to portray e-cigarettes as safe.

British researchers have looked at the effects that e-cigarettes can have on the respiratory system and they have found evidence suggesting the vapor can disable important immune cells in the lungs, which could lead to inflamed tissues.

The conclusions came after scientists tested the effect of condensed e-cigarette vapour on alveolar macrophages taken from lung tissue samples extracted from eight non-smokers. None of the participants had ever suffered from asthma or COPD.

Exposure to the fluid itself increased cell death and the production of oxygen free radicals 50 times, the researchers added.

The study shows that e-cigarette vapor can do harm although it is not certain it will do harm. It believed that e-cigarettes can help one overcome the habit of smoking and should be allowed on prescription.

Moreover, cells exposed to vaped fluid were unable to fight off bacteria.

The results of this study are at odds with an independent review conducted by Public Health England earlier this year which said that e-cigarettes are at least 95% less harmful than smoking.

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

Professor Thickett warned that, despite them being safer than fags, more research is definitely needed.

"We have to be careful when we promote these as safe", said Hill, who is also director of clinical research at Waterbury Pulmonary Associates, in CT. Well, now they say switching from warm smoky air to cold apple-flavoured air isn't all that fantastic a change to make, as huffing vapourised chemical compounds gives your lungs an entirely new collection of shit to deal with.

The report was published online August 13 in the journal Thorax.
