Is Vaping Worse Than Smoking?

So I suppose you heard about the latest e-cigarette study, the one that said that the vapors e-cigarette users inhale contain multiple forms of formaldehyde. It was much in the news last week, after its authors, five scientists from Portland State University, published a peer-reviewed letter outlining their findings in the prestigious New England Journal of Medicine.

Vaping“Before You Vape: High Levels of Formaldehyde Hidden in E-Cigs,” said the headline at NBC.com. “Can You Guess What Cancer-Causing Agent Researchers Just Found in Electronic Cigarettes?” asked The Motley Fool. “E-Cigarettes Not Safer Than Ordinary Cigarettes,” claimed the online publication Tech Times. The New England Journal of Medicine chimed in with a tweet of its own: “Chemical analysis of e-cigs’ vapor show high levels of formaldehyde,” it read. “Authors project higher cancer risk than smoking.”

The study focused on a device known as a premium vaporizer that heats a flavored liquid containing nicotine. The heat causes the liquid to turn into vapor, which the user inhales. Most of these devices also allow the user to control the voltage. These devices have become increasingly popular as a way to ingest nicotine without smoking.

In the study, the Portland State scientists ran the device at both a low voltage and a high voltage. At the low voltage, they did not detect formaldehyde. But at the high voltage, they found some. Formaldehyde is, indeed, a known carcinogen, which also exists, among hundreds of other toxic chemicals and dozens of cancer-causing agents, in combustible cigarettes. The authors concluded that someone who was a heavy user of a vaporizer at the high voltage was five to 15 times more likely to get cancer than a longtime smoker. Or so they seemed to say.

There is not much doubt that studies like this have an impact on the public perception of e-cigarettes. Even though cigarettes result in 480,000 American deaths each year — and even though it is the tobacco, not the nicotine, that kills them — many in the public health community treat e-cigarettes as every bit as evil. Every dollop of news suggesting that vaping is bad for your health, much of which has been overblown, is irrationally embraced  by anti-tobacco activists. One result is that, whereas 84 percent of current smokers thought e-cigarettes were safer than ordinary cigarettes in 2010, that number had dropped to 65 percent by 2013.

Worse, close to a third of the people who had abandoned e-cigarettes and returned to smoking did so because they were worried about the health effects of vaping, according to a study published last year in the journal Nicotine & Tobacco Research.
