After a few months, I got tired of hearing my wife cough. It was starting to scare me and her, so I made her and my sister-in-law a bet. I gave them each $200 in cash and told them the cash was theirs, but for every cigarette they smoked in the next 10 days, I got $10 back. I gave them both an e-cig and some different flavors of e-juice and added a friendly bonus wager of $100 in lottery tickets to whoever smoked the least during the 10 day period.

In other words, despite acknowledging that they cannot tell from their study whether e-cigarette use precedes smoking or whether smoking precedes e-cigarette use, they nonetheless draw the conclusion that e-cigarette use precedes smoking.

The study analyzed the levels of a large number of pollutants in the ambient air of a room in an office building during the presence of three smokers using electronic cigarettes. The room was moderately ventilated at 0.56 air changes per hour.

Nevertheless, this does not stop the authors from drawing a conclusion. They conclude, despite their acknowledged inability to draw such a conclusion, that: "e-cigarette use is aggravating rather than ameliorating the tobacco epidemic among youths."
