When inhaled vaping liquid condenses in the lungs and seems to disable key protective cells a University of Birmingham study revealed

According to the study conducted by researchers at the University of Birmingham, the vapor inhaled from e-cigarettes damages immune cells and prevents them from clearing out harmful bacteria.

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

"In terms of cancer-causing molecules in cigarette smoke, as opposed to cigarette vapour, there are certainly reduced numbers of carcinogens", Professor Thickett said.

I do not believe that electronic cigarettes are more harmful than normal, but we should have a cautious skepticism as to whether it is as safe as we think.

Therefore, the study's researchers have warned people to do away with the perception that e-cigarettes are safer. Britain's public health authorities are pushing smokers to switch to it as a safer choice; experts in the United States 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.

Researchers from University of Birmingham and Swansea University in the United Kingdom devised a mechanical procedure to mimic vaping and produce condensate from the vapour.

Previous studies have focused mainly on the chemicals that contain the electronic cigarette fluid before steam, but the new study focuses on steam itself.

Danny Cipriani pleads guilty to two charges after Jersey nightclub incident
Gloucester Rugby have come to the defence of star flyhalf Danny Cipriani following his court appearance in Jersey this morning . Cipriani was arrested in the early hours of Wednesday morning after the incident in The Royal Yacht Hotel and Spa, St Helier.

Recent news revealed that vaping - which is supposed to be an alternative to cigarettes - is actually way more damaging to our body than we initially thought.

Alveolar macrophages from lung tissue samples were extracted and provided by eight non-smokers who were suffering from asthma or chronic pulmonary disease (COPD).

"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". The US Surgeon General has however issued warnings that use of e-cigarettes among the young can lead to several problems such as nicotine addiction, mood swings and impairment of brain development.

Martin Dockrell, who is the lead for tobacco control at Public Health England, said: "E-cigarettes are not 100% risk-free but they are clearly much less harmful than smoking".

This week the government's Science and Technology committee would release a report on the safety of e-cigarette smoke.

That said, they are still better for you than smoking.

Switching to e-cigarettes could help smokers to give up smoking, it added.
