The rest of the story is that the 2014 Surgeon General's report is violating the very ethical principles that it attacks the tobacco company for violating in the past. While there has been substantial progress in the past 50 years in the area of disclosure of conflicts of interest, somehow that progress has evaded the producers of the Surgeon General's report itself.

Today, I reflect on what this story demonstrates about the scientific bias that is apparent in the anti-smoking movement, particularly among researchers like Dr. Glantz, who has repeatedly misinterpreted scientific studies in order to skewer electronic cigarettes.

Let’s break down the base shall we Nicotine, VG (Vegetable Glycerin), and PG (Propylene Glycol) are found in every bottle of E-Juice. This base makes up 85% to 95% of the bottle of E-Juice that you are paying for, and it is virtually identical in every bottle. There is no such thing as “premium” PG or “premium” VG; it is all one in the same. The other percentage is just the flavoring, and this is where the term premium could come into play. There are dozens of different flavoring manufacturers out there. Some in the USA others overseas such as Italy and even China (not good) and all with a different price point. Generally speaking, the imported flavorings (not the Chinese ones) do cost more than the flavorings from stateside and from my experience no two flavoring companies are really the same. The Flavor Apprentice is a very popular choice when it comes to E-Juice making, mostly because it is dirt cheap to order in bulk compared to companies like Lorann or even Capella; both of which have a higher price tag. In short there is such a thing as premium flavoring, but no E-Juice vendor would be willing to reveal the secrets of their trade and inform you what company they’re ordering from even if they are calling it “premium” E-Juice.

Stated another way, Dr. Glantz is cautioning the FDA against assuming that e-cigarettes are safer than conventional cigarettes in terms of their effects on lung function.

Dr. Glantz is simply wrong. There is abundant evidence which demonstrates that while vaping does cause some degree of respiratory irritation (and probably triggers a bit of inflammation), it is far safer than smoking and has far less of an effect on lung function.
