Smoking and Tobacco
Nicotine-free e-cigarettes were harmful to blood vessels after just one use, according to study results published in Radiology.
“While e-cigarette liquid may be relatively harmless, the vaporization process can transform the molecules — primarily propylene glycol and glycerol — into toxic substances,” Felix W. Wehrli, PhD, director of the Laboratory for Structural, Physiologic and Functional Imaging and professor of radiologic science, biochemistry and biophysics in the department of radiology at the University of Pennsylvania Perelman School of Medicine, said in a press release. “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.”
