Even nicotine-free e-cigarettes are not safe, a new study suggests.

Vaping heated, flavored liquid still damages the blood vessels when nicotine is absent, according to a new University of Pennsylvania School of Medicine study.

Researchers - Heat - Chemicals - Particles - Distress

Researchers there found heat morphs the chemicals in e-liquids into toxic particles that distress and damage the blood vessels.

Their findings come amid an alarming slew of lung disease cases among patients who have one thing in common: vaping, whether it be using e-cigarettes infused with nicotine, cannabis or something else.

Cigarettes - E-cigs - US - Health - Officials

Initially billed as a quit-aid and safer alternative to smoking combustible cigarettes, e-cigs have quickly become one US public health officials' greatest concerns.

Smoking is dangerous in part because it involves burning plant matter, particles from which lodge themselves in the lungs and put stress on the cardiovascular system, and because cigarettes contain harmful substances like tar.

E-cigs - Decade - Research - Subject

E-cigs have been around for about a decade, which makes them a relatively new research subject.

They may lack tar and some of the definitively carcinogenic chemicals in traditional cigarettes, but the more they're studied, the more clear it becomes that even if the devices are 'safer' they are certainly not safe.

Studies - Juul - Teenagers - Impact - System

Previous studies have found that popular nicotine e-cigs - like the trendy Juul that so many American teenagers have become addicted to - have effectively the same same impact on the cardiovascular system that combustible cigarettes do.

How exactly they do this damage is less well understood, but some scientist suspected that the stimulant effects of nicotine were to blame.

U - Penn - Study - Journal - Radiology

But the new U Penn study, published in the journal Radiology, suggests otherwise.

To test the effects of nicotine-free vaping on blood vessels, the researchers took MRIs of 31 volunteers who use these types of e-cigs - but don't smoke - before and after vaping.
