They did not report their methods for the ecig sample acquisition. It's quite possible that they were not using the vaporizer under the normal conditions. There was a previous study where they were running the device at excessive voltages over tens of seconds, causing pyrolysis which would never happen under normal usage. Simply because it would taste awful and make the user cough a lot. I would have liked to see control experiments: analyse the e-liquid without vaporization, and analyse pure glycerol/propylene glycol. The former may show a response, but the latter should not show any at all.

Here it is documented a bit: http://pubs.acs.org/doi/abs/10.1021/acssensors.7b00118 http://pubs.acs.org/doi/abs/10.1021/acssensors.7b00118 http://pubs.acs.org/doi/suppl/10.1021/acssensors.7b00118/suppl_file/se7b00118_si_001.pdf http://pubs.acs.org/doi/suppl/10.1021/acssensors.7b00118/sup...

  It's not though. No mention of the device, eliquid, device parameters (power or temperature depending on the model), or puff duration. It's a pretty significant omission.

Exactly, as anyone who used ecigs knows, if you pull when the coil is too hot, you get what i'm assuming is formaldehyde and friends. when used normally, the ecig should only vaporize the PG and nicotine (2 ingredients). if you burn the mixture, that's where you get a cocktail of chemicals akin to a cigarette it's admittedly hard to describe but a really vital difference. its the difference between warming a cookie and burning a cookie. the soot from the burnt cookie is way more toxic than a properly warmed cookie that said, i welcome more information about e-cigs for sure. but as an ex-smoker who used ecigs's step-down method and finally quit last year, we need to be very careful before crucifying this very effective cessation device
