+1, but I think it's done for the mental satisfaction of creating some sort of a visible reward, and for this crowd, it seems to be more about making a statementWhy can't a company manufacture 'Stealth Carts'? Basically instead of PG or VG find another substance to carry the nicotine that isn't visible. I know some of you would likely balk at this idea, but, to others its a reasonable compromise. Obviously you would only use them in certain situations/areas.
The idea being that if all you are doing is sucking on a piece of plastic nobody can get upset about it. It may not even be possible, because I believe the PG/VG is what the nicotine is dissolved into. However, at some point down the road it seems feasible to me they could come up with a way to transport the nicotine via invisible or nearly invisible vapor.
Anyway, just a thought. I'm sure somebody or some company must have though of this before, must not be possible yet though.
I'd totally go for some Stealth Carts though, would come in handy for those rare occasions when I'm forced to travel outside of my house, lol.
BTW, apologies if somebody else mentioned this idea. I only read about halfway through this thread before posting. It's 24 pages! hehe

I'd say they should develop an invisible vapor for occasions where visible smoke could be misconstrued.
