I tried an ecig the other day, non-nicotine. Haven't smoked in 10 or so yrs, don't even think about smoking. But after a few pulls on that ecig, which was VERY hard to pull on btw, all I wanted was a smoke. Just an observation. I think it is safe to say a young ecig vaper is well on their way to a nicotine habit. It is just a matter of time, they will be heavily regulated, or communities will outlaw until the jury is clear on what the consequences are.
