Will the e cigarettes be the next Crystal Pepsi?

They say "It's only water vapor"--but how long did it take for people to realize regular tobacco smoke was harmful to your health??
There are a couple of people at work that whip them out and puff away anytime they think they can get some shock affect or a reaction from someone. It is really- REALLY annoying.
I read that it can be used as a tool to help quit, but also read that they keep up-ing the strength of the liquid which can be harmful or even fatal.
I don't smoke and never have, so i just don't get it.
Now for a serious answer.
You don't smoke, so you really cannot get it. So you really cannot make your case by oversimplification as you attempted to in your first statement. Are the people at your work truly trying to get attention? Or are they getting a nicotine fix when they can, instead of smoking? Yes, all smokers realize that it is a habit that carries chronic diseases that may be untreatable at one point. The thing is, you can smoke for years and not feel any effects of the "bad for you" stuff. If it happened immediately, that would put a different spin on things wouldn't it?
Some folks that do not smoke, think it's the cool thing to do. Those are the ones that look like complete idiots, behaving in a way that leaves little doubt as to the observation I just made. But if the person genuinely wants to quit smoking for good, this is a breakthrough alternative that seems (up until now) to be working for many lost causes. I'm sure you may do some pretty annoying things at work as well, but the ecig showoffs may have enough tact not to mention it to you. Who knows. My research into the matter reveals that because they have not been FDA tested, they are NOT to be used as a smoking cessation device. As far as the "re-uping" statment you make, I do not understand what you are referring to.
I smoked for years and years. The habit really sucks the cash out of your pockets, makes you reek like an ashtray, and is in fact highly addictive, and can give you lung and other cancer. I decided to quit smoking once and for all. I asked one of the members here for some help with learning about the ecigs. Before that I tried patches, gum, lozenges, Chantix, they all sucked and didn't work. Also, without getting into any political garbage, more and more employers are moving to control what their employees do on and off the clock. Your employment may be contingent on your use of tobacco. Geico is one company that years ago or more moved to hire only those people that did not use tobacco. Yet they can be raging alcoholics or gambling addicts and they get a pass. Strange how these things seem to work.
I bought an ecig and I have not smoked a full cigarette in over a month now. I will cheat once in a while and light one, take a drag or two then throw it away. As far as the ecigs themselves, they are not created equal. You can buy a ton of stuff for them, tanks, batteries, mouth pieces, etc. Pimp it out as much as you want. The juice is made differently by different companies too. You can get it in just about any flavor and nicotine level you want. Intelligent people don't necessarily try to max out their nicotine levels, that is just not how the
nicotinic acetylcholine receptors in the brain function. You hit a satiation point, and you stop. The trick is to go down gradually until you wean yourself off of it once and for all. I hope this helps you get it a bit more than when you started the thread. I owe some thanks to Charlie Mike and Trivia Monster for the videos and heads up on what to buy.
