Well mate I have a GC trace, and I working with GC's for 9 years, with an accurate method, correct retention times and temperatures that also shows, benzenaline, toluene with a lot of other peaks boiling off at a ramp rate of 11°C/min up to nicotine at a max temp of 35°C. But besides that I was just mentioning that people should be cafefull when modding theyr equipment, but they way people jump on how wrong I am gives me no doubt about the addictivity of the habit or nicotine. I was trying to help not trying to advise anyone to stop vaping.

Also, w/ the exception of flavorings, I don't see how toluene can be synthesized from PG+nicotine alone. Actually, looking at molecular structures, it'd seem, while not impossible, basically impossible. You'd have to isolate the aromatic ring from nicotine (which'd be hard), convert the pyridine (5C+N) to a benzene (all C), AND add a methyl group. That, under most circumstances (and pretty much every circumstance we'd encounter) is impossible. While adding to the ring is do-able, replacing a Nitrogen for a carbon is like ridonkulous. The core aromatic ring, w/ delocalized electrons and all, are super stable. If there are contaminants, then maybe you'd find it and other chemicals. But that'd be an issue w/ the supplier. And studies so far have shown no such contaminants (that new one where scientists were "WOWED" by the lack of toxins (rather, the equivalent amount of toxins as in a breath) or Farsalinos' studies)
W/r/t flavorings, a few vendors do list the compounds and molecules. From a glance at TFA's site, I haven't seen mention of any toxic chemicals.
All that to say, your GC (which I'll assume's for gas chromotography) might be ...off? (unless you were just talking about potential for exposure IF said toxins were found). Or like you really need to find a new supplier. Or clean the gear you have (machine oils?)
The zeal w/r/t vaping likely isn't due to the "addictivity of the habit or nicotine." It's probably more the current and potential future state of affairs- the general consensus with policy makers and the public w/r/t vaping based of dis-information, either intentional (cigarette lobby? disingenuous politicians?) or unintentional (studies concluding danger despite flawed methodology) Vaping isn't smoking and shouldn't be considered as such (let alone taxed as such [eg Chicago's "sin tax" (not sure if vapings lumped there since I started vaping after I moved away, but I wouldn't be surprised)])
