Over paranoid?

[Proverb]

Yes, in fact, they did, which has been covered extensively in other posts. Of course the amount that they found was equivalent to what has been found in regular tobacco cigarettes.

This is what many of the pro-vape activists are trying to do. Get the TRUTH out there. Not speculation.

Not to nit-pick, but in the spirit of your last statements, the amount of DEG that was found by the FDA was merely reported as trace amounts; meaning, statistically unquantifiable amounts, but still able to be picked up by their detection methods, which claim to be capable of parts per trillion. Furthermore, this was found when the whole liquid was analyzed, not the vapor. And finally, there was no equivalence associated between the amounts of DEG and a typical cigarette. I think it would be a gross exaggeration based upon speculation to say that the DEG amounts found in the what we vape to be as high as the amounts found in regular cigarettes.

To go back to the OP though here's what I've gathered:

1. PET generally safe, though people still have their cause for concern. In comparison to pure cotton though I'd be hard pressed to say it's more dangerous. Cotton has a much lower burning point, and so if you let your atty run dry at times you may be singeing the cotton and thus inhaling smoke too.
2. PG is generally recognized as safe. To put things in perspective, from 1972-2005 there have only been THREE deaths reported that are linked to Propylene Glycol (http://www.astm.org/JOURNALS/FORENSIC/PAGES/JFS2004460.htm)*. It, along with water, are used in non-toxic antifreezes for things like swimming pools. To put things in perspective, the annual deathrate for drowning, or water related deaths, is 3300. Over the 33 years in which the THREE people have died from PG, 108,900 people have died due to water. And that's not including the lack thereof. Another way of looking at it, is for everyone ONE person who died due to PG, 36,300 people have died due to drowning. That's just crazy. I mean think about it. An essential to life causes more deaths than PG. 1:36300.

*Excluding drownings, even just a cursory glance will at the different news stories out there will show that a far greater number of people have died due to drinking too much water than deaths that have been reported due to PG consumption. The three deaths were due to suicide, in which the victims drunk large quantities of the substance. PG is not water, nor should it be treated as something consumable; however, its toxicity in adult humans is extremely low. We vape on the single digit ml levle and so the toxicity should be even lower.

All of that worry and none of it focused at the only real thing that should cause caution... the nicotine

And re:cotton, see this from the other thread:
