Interesting watch, I'll have to go back some time and watch the Hobbs portion. It sounds like nicoventure is at least taking a more correct approach, in analyzing the aerosol. I wish they would not have taken the first step of eliminating "carcinogenic and other" known hazards, because that data would be beneficial, even if it isn't necessarily profitable. Seems like, for menthol at least, the aerosol is not toxic whereas smoke is.
I'm not a scientist but I have issues with their assumptions used for their computer models. They say longer puff time means deeper lung exposure, but I didn't see any mention of particle size, or any kind of measure of how much is absorbed in the tissue leading down to the lungs. I take two second puffs, but very little actually makes it to my lungs, because I don't lung inhale. I still think we need a better understanding of how the products we use act within our bodies.Not exactly a study but an analysis of current literature prepared by a toxicology consultant :
