That DEG bit has nothing to do with them using tobacco, and instead has everything to do with a company in China not using USP Propylene Glycol (as non-USP PG might contain some DEG.)

And just to elaborate on this, non-USP PG is used everywhere. If you cook and use flavorings, take a look in your cupboard and check out the ingredients. PG will no doubt be used as a carrier in some of them. Aside from flavorings it's also used in the manufacture of many foods: my grandfather, who works at a cheese house, told me they use it in their process and it no doubt gets into the production.

The nitrosamines are from the nicotine extraction, which again indicates that they were probably not using USP nicotine. The company that produced that particular e-cigarette is now out of business.

The dose makes the poision; analyze everything around you and you may find a very small percentage of unwanted and dangerous chemicals.

Conflating the e-cigarette industry with the tobacco industry is entirely incorrect. The e-cig industry was not started by a tobacco company, and big tobacco has only recently taken interest by buying up companies and starting their own brands.

Also note, that the amount of DEG and nitrosamines were well within acceptable standards enforced by the FDA. The whole media circus around it was very shady.

Very good point. Toxicologists hate the term "poison" because it is misleading. Water is poisonous when we take too much.

There was some terrible anti-ecig research recently that reported all of this dangerous stuff in them (still vastly less dangerous if you look at it merely because there is no burning lignins).

Anyhow, the flaw in this study was burning e-liquid at 900 degrees C, the temperature of the cone of a burning cigarette, versus the 200-250 C of an ecig. It is sort of like saying a car isn't safe to drive on a highway because we tested it at 200 MPH.

All of these people raising concern in this thread, writing NYT articles, etc. are not informed about the body of research and able to put it in perspective.

BTW, with how much is consumed on average taken into account, FDA-approved gums/patches contain more tobacco-specific nitrosamines than ecigs (and this is so minor to not be a concern).
