Just 30 minutes of vaping damages the lungs

Gulf Today Report

A new study conducted by the University of California, Los Angeles (UCLA) found out that vaping for just 30 minutes increases oxidative stress levels two to four times higher than baseline levels in people with no previous smoking history.

Just one vaping session can cause stress that leads to serious lung damage and puts a person at risk for heart or neurological disease, as well as putting a person at increased risk of developing cancer, Alzheimer’s disease and other conditions a new study finds. Oxidative stress describes the damaging effects that free radicals (unstable molecules) have on the body.

It refers to the imbalance between free radical cells and antioxidants.

Free radicals are harmful oxygen cells that can cause tissue damage and antioxidants are responsible for fighting their harmful cells.

Researchers found that non-smokers would have two to four times as many cells that test positive for oxidative stress after just 30 minutes of vaping.

However, little overall change was found for people with a smoking history.

For the study, the researchers gathered 32 study participants ages 21 to 33.

They were divided into three groups based on their history of cigarette or nicotine use. The volunteers included nine regular cigarette users, 12 e-cigarette or vaping users, and 11 non-smokers.

The team collected a type of immune cell called CD45 from all participants, both before and after a 30-minute vaping session.

While those with little smoking history still had lower oxidative stress levels than the regular smokers, their CD45 immune cells tested positive for oxidative stress at a two- to fourfold increased rate.

“We were surprised by the severity of the effect one vaping session can have on healthy young people,” said Dr. Holly Middlekauff, a professor of cardiology and physiology at UCLA. By 2020, nearly 40 per cent of high school students who regularly smoke nicotine did so with an e-cigarette, according to one report by Tobacco Free Kids.
