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
