I'm not sure they did much research really. Hell the article even states that a cartridge is equivalent to a pack of cigs which can't be true unless he's selling e-cigars perhaps (not familiar with the brand mentioned). It would be a ..... to get slapped with the same regulations, especially since we all know that the vapor doesn't linger like smoke, although I suppose that's really just a visual thing and might not have any bearing on the actual health risks. Personally I use my e-cig at work discretely all the time. My co-workers know about it, but customers wouldn't know I just took a few drags moments ago. I've even found that if you exhale slowly through your nose the vapor becomes invisible. I'm actually somehwat eager to be disillusioned or vindicated on this.
