Vaping Is Far From Harmless

While cigarettes generally produce a thousand times more carbonyls because of the combustion process, e-cigarettes produce a varying amount depending on the ratio of glycol to glycerin in the vaping fluid and how much of it is heated, says Daniel Conklin, an environmental cardiologist at the University of Louisville. Conklin has investigated how e-cigarettes might affect cardiovascular disease using a type of mouse bred with a disorder that mimics heart disease seen in humans. Acrolein is of particular concern because it is considered to be the main contributor to the increased risk of cardiovascular disease among cigarette smokers, he says.
