E-cigarette vapour disables lung’s protective cells

E-cigarette vapour disables lung’s protective cells

The findings, published online in the journal Thorax, suggest that while further research is needed to better understand the long term health impact of vaping, e-cigarettes may be more harmful than we think, as some of the effects were similar to those seen in regular smokers and people with chronic lung disease. "But we should have a cautious scepticism they are as safe as we are being led to believe".

"Importantly, exposure of macrophages to [e-cigarette vapour condensate] induced numerous same cellular and functional changes in [alveolar macrophage] function seen in cigarette smokers and patients with COPD", they said.

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.

According to a study, it can damage immunity, disable cells in the lungs and cause inflammation, a BBC report says.

However, Public Health England advises they are much less harmful than smoking and people should not hesitate to use them as an aid to giving up cigarettes.

Those responsible for the study said that their results urge "caution against the widely held opinion that e-cigarettes are safe".

They set up a machine that replicated the effect of vaping and studied what happened to the samples of tissue.

Although electronic cigarette is safer than normal cigarettes, it poses its own risks and may prove more harmful over time than previously thought, according to a new scientific research. The vapour from e-cigarettes impairs the activity of alveolar macrophages, which engulf and remove dust particles, bacteria and allergens that have evaded the other mechanical defences of the respiratory tract.

But scientists and health officials across the world are now divided over the safety of e-cigarettes. The cell death also rose by fifty fold when exposed to the vapours.

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

Professor David Thickett, lead author from the University of Birmingham, said: 'I don't believe e-cigarettes are more harmful than ordinary cigarettes.

A survey of adolescents by researchers at Coventry University showed less than half of e-cigarette users knew vape products contained nicotine.

Britton said: "This indicates that long-term use of electronic cigarettes is likely to have adverse effects, as is widely recognised by leading health authorities in the United Kingdom including the Royal College of Physicians and Public Health England".
