Vaping warning: E-cigarettes ‘may be more harmful than we think’

The vapour could apparently lessen the effect of alveolar macrophages cells, which remove dust particles, bacteria and allergens.

Although advised by health experts as safer than cigarettes and ideal for use by smokers looking to quit, researchers are now cautioning against this advice.

Researchers found vapour boosts production of inflammatory chemicals and disables key immune cells in the lungs that keep air spaces clear of potentially harmful particles.

While vaping is safer than traditional cigarettes, they may still be harmful in the long-term, he warned.

In an experimental study led by Prof David Thickett, a mechanical procedure was used to replicate vaping in a laboratory at the University of Birmingham.

One-third of the cells were exposed to plain e-cigarette fluid; one-third to different strengths of artificial vapor with and without nicotine; and one-third were exposed to nothing for 24 hours.

For the cultured cells, exposure to e-cigarette vapour induced numerous same changes in lung macrophages that have been seen in cigarette smokers and patients with COPD, the researchers note.

She commented just hours after Trump's campaign announced it was filing an arbitration action against her, alleging violations of a secrecy agreement she signed.

Amidst this controversy, the Birmingham researchers extracted immune cells or alveolar macrophages, from lung tissue samples that were taken from eight non-smokers who were never diagnosed with asthma or COPD.

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

However, the study stated that the effects are similar to those seen in regular smokers and patients with chronic lung disease. "They are safer in terms of cancer risk, but if you vape for 20 or 30 years and this can cause COPD, then that's something we need to know about", he stated.

They created a mechanism to mimic the effects of vaping, as well as to turn the smoke back into a liquid afterwards.

The study shows that e-cigarette vapor can do harm although it is not certain it will do harm.

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. "The current study does not address that question, but given the much lower levels and range of toxins in electronic cigarette vapor relative to cigarette smoke, the answer is likely to be substantially less", Professor John Britton, Director of the UK Centre for Tobacco & Alcohol Studies at the University of Nottingham, who was not involved in the study, told the Science Media Centre. Treatment with an antioxidant, however, restored that ability and helped reduce other damage caused by e-cigarette fluid, Thickett's team found.
