I totally agree with 420.
Doing something, anything...is a choice. I hardly think a non-smoker is going to stick a NASTY tasting analog in their mouth just because they ran out of some very tasty liquids. I just cannot even imagine.
I'm a beer drinker that occasionally has vodka or tequilla. I've had a bottle of Gin in my cabinet for over 2 years that's left over from a party I had.
When Gin is the only thing in my cabinet I certainly am NOT going to drink it because it's gross.
I also have a bunch of beedies from Saudi Arabia, had them when I was a smoker but I didn't smoke them when I ran out of cigarettes because they are nasty (to me).
When I run out of toilet paper I certainly don't use my towels.
When I run out of spinach I don't use grass from the yard.
I know you'll all have something to say about my analogies...but it is what it is, just an analogy. I'm sure we could all come up with 100's of them.
To the OP, I think it's great that you found this. You smoke hookah so it's even more understandable that you've come to find PV's a great way of delivering flavor to your mouth with 0 nicotine.
Have fun with it and let us know how you like it!
Oh and welcome to ECF!
