Study: Vaping can Damage Immune System Cells

Previous studies have focused on the chemical composition of e-cigarette liquid before it is vaped

Vaping can damage vital immune system cells and may be more harmful than previously thought, a study suggests.

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

A small experimental study, led by Professor David Thickett, at the University of Birmingham, showed that in only over 48 hours the vapour from e-cigarette caused inflammation and impaired activity of alveolar macrophages — cells that remove potentially damaging dust particles, bacteria and allergens.

For the study, the researchers devised a mechanical procedure to mimic vaping in the laboratory, using lung tissue samples provided by eight non-smokers.

The research which is still in its infancy was published online in the journal Thorax.

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

“They are safer in terms of cancer risk — but if you vape for 20 or 30 years and this can cause COPD (chronic obstructive pulmonary disease), then that’s something we need to know about.”

“We should have a cautious scepticism that they are as safe as we are being led to believe,” Thickett said.

Thickett said some of the effects were similar to those seen in regular smokers and people with chronic lung disease.

He, however, caution the results are only in laboratory conditions and advise further research is needed to better understand the long-term health impact.

This is a “caution against the widely held opinion” that vaping can be used to aid in giving up cigarettes, the researcher said.

Study Reveals Exposure To E-Cigarette Vape Is Unsafe For Children

Although e-cigarettes, found comparatively safer than cigarettes in terms of harmful substances released, may prove no less harmful when used in the presence of children or inside homes and cars.

Believing that exposure to e-cigarette vape is safe for children, parents are increasingly vaping both at home and in car, finds a study.

The study showed only 38 per cent of parents who smoked cigarettes and 22 per cent dual users were found to strictly restrict cigarette use in both home and car.

On the other hand, 56 per cent of both e-cigarette users and dual users reported using e-cigarettes in their cars with children around. The research included 750 parents.

“The finding that a large majority of parents are vaping e-cigarettes inside homes and cars is an alarming trend,” said lead author Jeremy Drehmer at the Massachusetts General Hospital in the US.

“Our results suggest parents perceive it’s safe to use electronic cigarettes and are not taking the same precautions they do to protect their children from exposure to traditional cigarettes,” Drehmer said.

Carcinogenetic volatile organic compounds have been detected in the urine of e-cigarette users, and e-cigarettes leave deposits of nicotine on surfaces when used inside, according to the paper published in the Pediatrics journal.

Drehmer said parents have been misled by the marketing of vaping products to believe that the aerosol produced by them is harmless to children.

The researchers said tobacco majors market e-cigarettes as healthy products without warning about the harms to infants and children from nicotine and ultra-fine toxic particles that spread into the air and coats surfaces.
