Smoking E-cigarettes Increases Risk Of Developing Lung Disease

"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.

As he said, "with regard to the carcinogenic molecules contained in regular cigarette smoke, electronic vapor certainly contains fewer carcinogens".

Not only that, they are also safe for second-hand smokers, but Prof Thickett still insists that e-cigarettes are harmful. 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.

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

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.

"There is an agenda to portray e-cigarettes as safe", Thickett said.

According to latest research vaping using e-cigarettes can hasten the death of lung cells by up to fifty times and cause serious lung diseases later in life.

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

While vaping has regularly been touted as a safer alternative to cigarette smoking, emerging research is starting to paint a different picture.

Professor John Britton, director of the UK Centre for Tobacco and Alcohol Studies at the University of Nottingham, said: "This [study] indicates that long-term use of electronic cigarettes is likely to have adverse effects, as is widely recognised by leading health authorities in the UK, including the Royal College of Physicians and Public Health England".

Cells exposed to vapourized liquid also were not as good at battling bacteria, suggesting that e-cigarette users' lungs might have more trouble fighting off infections.

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. Lung tissue samples provided by non-smokers were used to carry out the experiment. It believed that e-cigarettes can help one overcome the habit of smoking and should be allowed on prescription.
