You imply empirical study here. It is unlike such a study ever gets done because it is much easier to look at ingredients of e-liquid and become more convinced. And by the time such study gets done most people have likely left this forum.Thad...really. Have you thought past the humerous PSA. What will be the backlash? We've already had groups monitor this very site to glean info that was cited in the court case with the FDA. Do you really think there will be no counter to your efforts indicating that you correctly quote the SHS danger, but seperate SHV from SHS, without proof?
Using another's info from research for comparison and contrasting is a fair and balanced way to present info...what you propose is no contrast just an illusion based on ...faith???...the PV and it's output (SHV) is not a hazard.
Get a chemist and prove it...there are a few on the board. Most studies on vapor refer to inhalation...not what we exhale. Once you see studies on exhalation you may become more aware of the difficulty in isolating confounding variables. The biggest one is obvious..air pollution, digesting (and off-gassing) a meal of cotinine rich foods such as eggplant with tomato sauce, individual genetic predisposition, age,...the list goes on and on.
I believe we have a failure to communicate because I understand these reports as a gathering of current research to inform the populace of trends. The sections begin, as all research papers do, with a historical review to date...than adds current work. Every research paper that gives any findings is based on an hypothesis. The hypothesis is proved or disproved via a "risk" analysis but almost always contains the terms...appear, may, seem to, and so on. The reason for the terminology is simple...the research needs to be replicated by other scientists before the value of the study is weighed.
Fortunately research on similar fields also adds to similar work. To imply that exhale vapor would be more dangerous than inhaled vapor would require chemical reaction to take place and I have never heard of this kind of effect be proven. Mixing jelly with mustard does not turn the mix toxic. And that is why the burden of proof is on the opposing side.
