Vaping damages lung tissue after one use even without nicotine

In just the past month, there’s been a rash of hospitalizations whose only common factor is vaping. At least one person has died. Given the great popularity of vaping with younger people, and its fairly recent explosive rise in use, the Centers for Disease Control and Prevention are already actively investigating the causes of these hospitalizations and whether even the discussion of risks below is understated. https://www.npr.org/sections/health-shots/2019/08/16/751823475/whats-behind-a-cluster-of-vaping-related-hospitalizations

Here’s a description of the apparent problem, as known so far: https://www.ecowatch.com/vaping-health-blood-vessels-2639938271.html?

Vaping Damages Blood Vessels After Just One Use, New Study Says

Health + Wellness

Vaping impaired the circulatory systems of people in a new study.

Vaping one time — even without nicotine — can damage blood vessels, reduce blood flow and create dangerous toxins, according to a new study published in the journal Radiology.

The study found that the heat created when e-cigarettes turn liquid into vapor stirs the compounds into toxic particles, which damage blood vessels. To perform the study, researchers at the University of Pennsylvania Perelman School of Medicine took an MRI scan of 31 healthy non-smokers before and after vaping nicotine-free e-cigarettes.

The study participants took 3-second drags 16 times on an e-cigarette that had tobacco flavoring and sweeteners, but no nicotine, as NBC News reported. The researchers found that after vaping, blood flow decreased in the femoral artery — the main artery that delivers blood to the thigh and the leg. In fact, the participants had had worse circulation, stiffer arteries and less oxygen in their blood.

“The results of our study defeat the notion that e-cigarette vaping is harmless,” said Felix Wehrli, the study’s principal investigator, as Wired reported.

“Beyond the harmful effects of nicotine, we’ve shown that vaping has a sudden, immediate effect on the body’s vascular function, and could potentially lead to long-term harmful consequences,” he said in a statement released by the University of Pennsylvania.

The changes that Wehril and his team noticed reflect the same process in the initial steps of the development of cardiovascular disease, as CNN reported. Though, to be fair, that takes many years to develop.

Specifically, the researchers observed an average 34 percent reduction in the femoral artery’s dilation. They also saw that vaping led to a 17.5 percent reduction in peak blood flow, and a 20 percent reduction in oxygen in the veins, according to a press release statement.

The study’s lead author, Alessandra Caporale, said in a statement that these findings suggest that vaping can cause significant changes to the inner lining of blood vessels.

“E-cigarettes are advertised as not harmful, and many e-cigarette users are convinced that they are just inhaling water vapor,” Caporale 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.”
