The question your editorial board should be asking is not, "Is it safe to 'vape' ?" You should be asking, "Is it safer to continue smoking tobacco cigarettes?"

Users of e-cigarettes have coined the term "vaping" to describe their activity and distance it from smoking.

The device that generates the smokeless drag is called a marijuana vaporizer. ... In the past two years, more than a dozen manufacturers have sprung up as vaporizers have wafted to the surface of the culture. Which explains the bumper sticker in an Oakland cannabis cooperative: "Got vape?"

Google Books returns a citation for vaping ostensibly from 1983:

There have also been experiments with a "non-combustible" cigarette, looking much like the real thing, but again delivering a metered dose of nicotine vapour to the mouth. (The new habit, if it catches on, would be known as "vaping.")

—" New Society, Volumes 65-66: http://books.google.com/books?id=vakpAQAAIAAJ&q=vaping," New Society Ltd, 1983

However, Google Books occasionally gets publication dates wrong, so given the 22-year gap between this citation and the 2005 citation above, I'm taking this one with several grains of neological salt.
