Vaping may damage immune system and lead to lung disease, study suggests

With time these changes could lead to chronic obstructive pulmonary disease (COPD) just as it is seen in those who smoke regular cigarettes they add. COPD includes diseases such as asthma, emphysema and chronic bronchitis.

Although e-cigarettes probably pose less of a cancer risk than regular cigarettes, whether they are as safe as manufacturers claim is unclear.

It found that the vapour caused inflammation and impaired the activity of alveolar macrophages cells, which remove dust particles, bacteria and allergens.

According to a study, e-cigarettes, widely believed to be relatively safe, have now been found to cause damage to important immune cells in the lungs, reports the BBC.

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.

An independent review of the latest evidence on e-cigarettes was published by Public Health England in February. But since e-cigarettes have been around for only a decade, the effects of long-term vaping aren't known, he noted.

With or without nicotine, e-cigarette vapor increases inflammation and disables cells that protect lung tissue, human tissue tests reveal. But it appears that the vaping process itself can damage immune system cells - at least in the lab, Thickett said.

A new study suggest that e-cigarettes may not be as healthy as previously thought.

"However, since electronic cigarettes are used nearly exclusively in the United Kingdom by current or former smokers, the key question is how this adverse effect compares with that of exposure to cigarette smoke".

After 24 hours of exposure the total number of viable cells exposed to the vaped condensate was significantly reduced compared to the untreated cells, and condensate containing nicotine exaggerated this effect.

Prof Thickett then shared that he believes e-cigarettes are less harmful than ordinary cigarettes but he warned people to be wary about its safety.

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

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.

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".
