The rest of the story is that the next time you hear an organization claim that vaping may not be any safer than smoking, you will know that the group has no scientific credibility. It's just sad to think that the FDA is one of those groups.

• The truth is that there are at least 10 published studies that examined the health effects of electronic cigarettes. And this doesn't even include the more than 20 studies in which the chemical constituents of electronic cigarette liquids or vapor have been analyzed using gas chromatography/mass spectrometry.

The misinformation in the tobacco control field is so widespread that hardly a day goes by that an anti-smoking advocate somewhere doesn't publicly declare that smoking may be no more dangerous than vaping. Yesterday, it was the Sedgwick County Health Department (Wichita, KS), which wrote in an op-ed in the Kansas City Star:

Instead, I think that studies which specifically compare lung cancer risk between lifelong smokers of filtered vs. non-filtered cigarettes during the same time period are most informative regarding the relative cancer risks of these products. And multiple studies along these lines, including recent studies, have reported a slightly decreased risk associated with lifetime smoking of filtered vs. non-filtered cigarettes.

The Rest of the Story

Based on this single study, Dr. Glantz concludes: "the FDA must be extremely careful about assuming that e-cigarettes uniformly pose less risk than conventional cigarettes."
