Vaping Directly Linked to Wheezing in Adults, Says Study

However, the researchers maintained that the analysis cannot prove that vaping causes wheezing; it only identifies an association between the two

With vaping no less harmful than traditional cigarettes, a new study suggests it is associated with wheezing in adults, which is a precursor to serious health conditions including heart failure, lung cancer and sleep apnoea.

Wheezing refers to breathing with a whistling or rattling sound in the chest and is caused by narrowed or abnormal airways.

The study showed that people who vaped were nearly twice as likely to experience wheezing compared to people who did not regularly use tobacco products.

“The take-home message is that electronic cigarettes are not safe when it comes to lung health,” said Deborah J. Ossip, professor from the University of Rochester Medical Center in the US.

“The changes we’re seeing with vaping, both in laboratory experiments and studies of people who vape, are consistent with early signs of lung damage, which is very worrisome,” added Ossip.

For the study, the team included more than 28,000 adults.

The findings, published in the journal Tobacco Control, showed that adult vapers were 1.7 times more likely to experience wheezing and related respiratory symptoms such as difficulty in breathing compared to non-users.

Although electronic cigarettes are marketed as a less harmful alternative to cigarette smoking, many concerns remain related to the long-term health consequences of vaping.

With the emergence of small, sleek vaping devices that are used with nicotine pods in hundreds of different flavours, the researchers fear the number of young people who vape will continue to grow and that serious health consequences, including allergies, loss of immunity and subsequent infections will follow.

Even Short-term ‘Vaping’ can Cause Inflammation, Says Study

E-cigarette use has risen at concerning levels among both smokers and non-smokers and now researchers from the Ohio State University have found that even short-term vaping could cause cellular inflammation in never-smoker adults.

Using a procedure called bronchoscopy to test for inflammation and smoking-related effects, researchers reported a measurable increase in inflammation after four weeks of e-cigarette use without nicotine or flavours.

The study suggested that even short-term usage could result in inflammatory changes at a cellular level.

“Through the randomised clinical trial of healthy never-smokers over a month, we found that an increase in urinary propylene glycol, a marker of inhalation-e-cig intake, was significantly correlated with increased inflammatory response in the lung,” said the study’s first author Min-Ae Song from Ohio State University.

For the study, researchers recruited 30 healthy, non-smoking volunteers to directly assess the impact of tobacco and e-cig use on the lungs through bronchoscopy, an outpatient test in which a doctor inserts a thin tube through the nose or mouth to view the airways.

A small sample of lung cells was collected from fluid in the lungs.

Participants were randomised to a four-week intervention with e-cigs containing only 50 per cent propylene glycol (PG) or 50 per cent vegetable glycerine (VG) without nicotine or flavours.

Results from these tests were then compared to a separate control group of never-smokers.

Researchers did not see levels of inflammation higher than the controls, but there was an increase in inflammation among the users who inhaled more of the e-cigarette.
