Just one vaping session can cause stress that leads to serious lung damage and puts a person at risk for heart or neurological disease, a new study finds.
Researchers from the University of California, Los Angeles (UCLA) compared oxidative stress in the lungs of routine cigarette smokers, vapers and people with no history of long-term use of tobacco or nicotine devices.
Oxidative stress describes the damaging effects that free radicals (unstable molecules) have on the body.
Vaping for just 30 minutes produced oxidative stress levels two to four times higher than baseline levels in people with no previous smoking history.
While vapes are seen by some as a ‘safer’ alternative to using tobacco and cigarettes, data from recent years has shown that there are many negative effects of using the devices.
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
