KUALA LUMPUR, August 21 — Cardiovascular function changes after vaping e-liquids, even those that don’t contain nicotine, a new study shows.
CNN reported that the study in the journal Radiology published yesterday concluded, using MRI scans, that there are changes in blood flow within the femoral artery in the leg after just one use, but the chemical responsible for the changes couldn’t be determined.
“It normalises after a few minutes, but if someone vapes regularly, there’s a possibility that things might not go back to normal,” study author Felix W. Wehrli, professor of radiologic science and biophysics at the University of Pennsylvania’s Perelman School of Medicine, was quoted saying.
The changes researchers observed in 31 people was known to be the initiating steps in the development of cardiovascular disease, including atherosclerosis.
Dr Robert Jackler, founder of Stanford Research Into the Impact of Tobacco Advertising, reportedly said a number of chemicals used by the flavor industry may be safe when absorbed through the intestine, but no one knows the impact they can have on the lungs over a long period of time.
“There’s no doubt in my mind that vaping is safer than conventional smoking,” Jackler said, “but that doesn’t mean that it’s safe.”
