Tony Gwynn's at age 54 from repeated smokeless tobacco use is the reason why. While it is not common, traditional smokeless tobacco use is clearly associated with oral cancer. In addition, there is little evidence that as marketed and used in the United States, these products are helping a substantial proportion of smokers to stay off cigarettes.

Before anyone swears off electronic cigarettes completely (which is not the point of this article by the way) the levels of diacetyl and acetyl propionyl present are higher than the NIOSH standards, BUT they are severely lower than that of regular cigarettes. In terms of getting obliterative bronchiolitis, it is still a lot safer to use electronic cigarettes over regular cigarettes as the diacetyl and acetyl propionyl are much lower, but just because they are lower, we cannot dismiss diacetyl being in our E-Juices immediately. If they flavors do have diacetyl, they should be avoided if possible. In fact, TFA/TPA is coming out with a new line of custard and cream flavors (known as the V2) that contain little to no diacetyl in their flavorings. I am hesitant to believe there aren’t at least traces of diacetyl present as we already know even some fruit flavors have them. But hopefully it will meet the NIOSH standards with their new line. With TFA/TPA spearheading non-diacetyl rich flavorings, it is my hope that other flavoring companies are following the same practice. Electronic cigarettes are becoming increasingly popular every day; the flavoring companies need to meet the demands of the community and avoid diacetyl in their flavorings if possible.

The major implication of this decision is that it exposes the degree to which financial conflicts of interest are plaguing the current tobacco control movement. It should force anti-smoking groups and federal agencies to take conflicts of interest more seriously.

One reason why these conclusions are so dangerous is that they may lead smokers to figure that there is no value in their smoking outside the home. If thirdhand smoke is as harmful as secondhand smoke, then why bother smoking outside?
