Vaping, even temporarily, can affect the blood vessels in healthy people — even if the vape pod does not contain nicotine, according to a new study published in the journal Radiology this week.
Researchers from the University of Pennsylvania School of Medicine studied 31 volunteers, all of whom were healthy, non-smoking adults with an average age of about 24 years old.
The participants were monitored as they each took 16 three-second inhalations from a disposable e-cigarette. The researchers used an ePuffer withbut no nicotine in it. A research coordinator made sure sure the participants did not cough or swallow the vapor.
“These products are advertised as not harmful, and many e-cigarette users are convinced that they are just inhaling water vapor,” Alessandra Caporale, Ph.D., a post-doctoral researcher and lead author of the study, said in a statement. “But the solvents, flavorings and additives in the liquid base, after vaporization, expose users to multiple insults to the respiratory tract and blood vessels.”
“Lung damage is what we’re most focused on right now, but there’s so much more going on,” Dr. Diana Zuckerman, president of the National Center for Health Research, recently told CBS News. “There are chemicals in Juul and e-cigs and we’re not exactly sure what the impact is going to be because we haven’t seen it before.”
A study published in the journal Pediatrics last year found a number of different toxic chemicals in e-cigarettes, including one linked to several types of cancer. Some of the chemicals turned up even when teens used non-nicotine products like fruit-flavored vapes.
