I just noticed you are a metro east person! Carondolet here
Shiloh, more or less O'fallon... Illinois side, of course! XD
Anywho, had no idea this topic would be so heated, so I'd like to go ahead and add; Quite frankly, I'd rather vape that coaperize (yes, I just went there) since it's easier and I don't have to worry about scorching charcoal. I won't get on the topic of combustion occuring, since we use toaster wire to boil the same chemicals used in shisha. I've seen some nasty gunk buildup in my atties before.
That bein' said, once again, E-Liquid does NOT have a chance of producing the same potential carcinogens that hookah coaperizing does. Nicotine has been isolated and suspended in a choice chemical for our enjoyment. Woohoo! How bout we all just agree that, while there are some similarities and some differences, nothing beats a good vape.
Edit: And on the topic of hookah bars... Do any of the waiters or waitresses ever really know anything? I have heard of so many that hate hookahs because their bowls scorched in less that 10min...
