E-cigarette vapour disables lung’s protective cells

Researchers found e-cigarette vapour disabled important immune cells in the lung and boosted inflammation

"Importantly, exposure of macrophages to [e-cigarette vapor condensate] induced numerous same cellular and functional changes in [alveolar macrophage] function seen in cigarette smokers and patients with COPD [Chronic Obstructive Pulmonary Disease]". In terms of cancer risk, electronic cigarette is safer, but if you are fed for 20 or 30 years and this can cause COPD, then this is what the fighter needs to know.

"I don't believe that e-cigarettes are more risky than cigarettes but I think we should have a cautious scepticism that they are as safe as we are being led to believe".

They said that we need to do further research before it can be claimed to be as accurate as possible.

The vapour was found to boost the production of inflammatory chemicals and disable key protective cells in the lung that keep the air spaces clear of potentially harmful particles.

"There has been a lot of support for people to use e-cigarettes rather than traditional cigarettes because of the perceived safety of the e-cigarette process", lead researcher Dr. David Thickett said in a podcast.

Vaping e-cigarettes might not be as safe as people believe - and the devices should be treated with "caution", a new study has warned. But since e-cigarettes have been around for only a decade, the effects of long-term vaping aren't known, he noted.

What's more, the ability of cells exposed to vaped condensate to engulf bacteria was substantially impaired, although treatment with an antioxidant restored this function and helped lessen some of the other harmful effects.

A third of the cells were exposed to plain e-cigarette fluid, a third to different strengths of the artificially vaped condensate with and without nicotine and a third to nothing for 24 hours.The condensate was found to be more harmful to the cells than plain e-cigarette fluid. Lung tissue samples provided by non-smokers were used to carry out the experiment.

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

E-cigarettes don't proceed tar or carbon monoxide; two of the main toxins in cigarette smoke, said the NHS.

Public Health England (PHE) recommends smokers to switch to vaping saying that it is 95 percent safer than regular tobacco smoke.

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".
