Been using these forums for a while (Lurked for months before I made an account) and seen a lot of discrimination about people that switched to vaping from using hookah. Hell, even my first post on this site (looking for recommendations on gear) I was getting replies like "hookah isn't addictive, just quit" or "if you didn't smoke cigs then why start vaping". Let's clear some things out real quick...
First off, a hookah smoker (Using unwashed tobaccos like tangiers or nakhla) takes in more nicotine than your heavy cigarette smoker. Nicotine obviously is the addictive substance that vapes were designed to deliver. Just because we got it by boiling our tobacco rather than lighting it on fire does not mean that we didn't become addicted. Hookah is just as addicting as any other form of tobacco consumption. It's even more popular in some cultures than smoking cigarettes.
Second off, vaping is more similar to a hookah session than it is to smoking a cigarette. A lot of shisha tobaccos use vegetable glycerin. It helps make bigger clouds, keeps the tobacco wet so it doesn't cherry, and probably helps keep the flavoring evenly distributed. Not to mention a lot of people smoke flavored tobaccos from hookah, where as cigarettes just taste like cigarettes... Sure, you can get different kinds of tobacco and maybe some other stuff added (like clove) but you're never gonna run across a cigarette that tastes like a spiced chai tea or a white gummy bear (Two Fumari shisha flavors). Therefor, a lot of hookah smokers are switching over since they can get an almost identical experience that's theoretically much healthier for them. If nothing else, we don't have to worry about that drunk friend knocking over our vape and flinging hot coals onto the floor.
And lastly, even if people start vaping that don't have any sort of nicotine addiction... Just look at it like this... Hookah bars are becoming pretty popular (At least, around where I live) simply because you can inhale good tasting smoke that doesn't make you choke. If someone wants to pick up a vape with some 0 nic juice rather than go to a hookah bar and smoke tobacco, you should be encouraging them. There's nothing addicting about it and they could stop any day with absolutely no problem.
That's my little rant, aimed at all the narrow minded "e-cig" users out there that think in order to be a "real vaper" you need to have lit some tobacco on fire and inhaled it. Just wanted to throw this out there so maybe some of those people will open their minds and realize that just because they got addicted to nicotine through cigarettes it's not the only way.
