To be completely honest, Trueba et al. actually found that not only did taking an exam affect nitric oxide levels, but it also produced decreases in lung function measured by spirometry. This is something that has not been observed for electronic cigarettes.

"In terms of acute effects on respiratory function, active smoking is exactly equivalent to the effects of taking a math test."

If this is the kind of "scientific" reasoning that is going to guide the nation's decisions on how to handle tobacco products which are killing hundreds of thousands of Americans each year, then we may actually be better off reverting back to the "wild, wild west" that Stan Glantz keeps talking about. At least in that wild west, consumers are able to make reasonable judgments about the relative safety of different products. In the FDA-regulated "east," consumers are going to be kept hidden from even the most basic truths: that electronic cigarettes do not contain tobacco and that they are much safer than the real thing.
