A Royal Society for Public Health Guest blog: The Pleasure Principle.
By Michael Siegel
Dr. Siegel is a Professor in the Department of Community Health Sciences, Boston University School of Public Health.
Anti-vaping researchers and anti-smoking groups are now spreading the false information that when heated and vaporized, propylene glycol is converted into propylene oxide, which is recognized as a carcinogen.
For example, the Kenosha Racine and Walworth Counties Tobacco-Free Coalition claims that “Once heated into the vaporized form, propylene glycol is chemically changed into propylene oxide, which is a class 2B carcinogen as rated by the International Agency for Research.”
The problem is that there is something which Dr. Glantz and his colleagues are hiding and which the anti-smoking groups in Kenosha, Racine, and Walworth counties are also failing to reveal:
The “certain conditions” under which propylene glycol can be converted to propylene oxide are quite simple:
A temperature of at least 980 degrees Fahrenheit.
Since propylene glycol boils at 371 degrees Fahrenheit, and since e-liquids are not heated above that temperature (or even close to it), these conditions can never actually be reached in the vaping process. Therefore, it is simply untrue that when heated in a vaping device, propylene glycol is converted into propylene oxide, a recognized carcinogen.
Why do people smoke cigarettes even though vaping is healthier and cheaper? by @Cantiloper
Answer by Michael J. McFadden:
Some of the other answers are quite insightful and I'd agree with them. I would phrase it as there being five main reasons:
- Enjoyment: Some simply find smoking more enjoyable.
- Finances: Aside from the negative impact of the start-up cost, there's also a growing subset of smokers who avoid the bulk of the extra cost either/or by smoking roll-your-owns (RYO) or actually moving into the GYO (Grow Your Own) world of smokers. Within this group you also have a new category of smokers that didn't exist so much fifteen or twenty years ago: The Rebellious or Resentful — folks who've gotten angry over being targeted and seek to hit back at nasty Big Government, not just by RYO and GYO, but by seeking out and cultivating the black market regardless of its negative aspects. This group will not only be more likely to continue smoking because of tax increases, but will feel that every cigarette smoked without being taxed is a "victory" over their bete noir.
- Health/Safety: Significant subsets within The Greedy and The Moralist segments of the antismoking community seem to deliberately magnify any doubts or problems with vaping to the point where a good many smokers nowadays believe that vaping is actually more dangerous than smoking: after all, that's what the Cognizant Authorities seem to be telling them in the daily papers and on TV.
- Resentment: Some smokers have deeply resented the various attacks they've endured over the past twenty years and will continue to smoke simply because they don't want to give their "enemy" (i.e. the Antismokers) a victory.
- Innocence: There are still a good number of smokers out there (I'd seat-of-the-pants guess between 30% and 70%.) who simply haven't tried vaping yet since it's still fairly new, or have tried it at a very superficial level (usually using a single purchase of a "cig-a-like") and, simply finding it "not the same as smoking," never investigate further.
- MJM, who would likely fall largely into #1, though with elements of #'s 2, 4, and 5…
