E Cigarettes Research Paper
Chemical flavourings found in electronic cigarettes can cause irreversible lung scarring and other respiratory diseases, reported a Harvard study released Tuesday.
Published in the EHP journal, the findings suggest a direct link between e-cigarettes and the severe respiratory disease, bronchiolitis obliterans, or Popcorn Lung.
“In addition to containing varying levels of the addictive substance nicotine, they also contain other cancer-causing chemicals, such as formaldehyde, and as our study shows, flavouring chemicals that can cause lung damage," said Professor David Christiani, a co-author of the study.
The study tested 51 types of flavoured e-cigarettes sold by leading brands in the US.
Researchers used a device to imitate the action of a human smoker. The airstream of the e-cigarette was then analysed for the …show more content…
And levels of diacetyl exceeded the limit of detection in more than ¾ of the popular vaping products.
"Severe bronchiolitis obliterans [is an] an irreversible loss of pulmonary function that can become so severe that the only treatment option may be a lung transplant," the study says.
Other symptoms of the disease include lung thinning, skin peeling, night sweats, and severe shortness of breath. Doctors often misdiagnose the condition as either bronchitis or asthma.
Despite lacking medical research, e-cigarettes are not regulated by the FDA.
And unlike tobacco products, there is no age restriction on the purchase of e-cigarettes. The Centres for Disease Control (CDC) estimates that as of 2012, more than 1.7 million children have already tried out e-cigarettes.
The sales of the product are set to increase 17-fold from to 2013 to 2028.
Study authors recommended 'urgent action' for further evaluation on the potentially widespread exposure of respiratory disease caused by flavoured e-cigarettes.
