The question is, do other things affect you like this on a regular basis? You can't get addicted to anything using it once. Don't know where you got that info. You can't even get addicted to heroin using it once. You can however have such a wonderful time with it you continue using it and then you get addicted, which is often confused with physiological addiction. Many people confuse habits with addiction. Addiction has a very limited definition; even antidepressants, which you really can't stop using without suffering withdrawal if you do it abruptly, isn't officially classified as addictive. I don't know anyone who didn't smoke tobacco a little. I do wonder what you thought you were smoking when you used a hookah -- it's just a big water pipe and you have to have something to smoke to have it do anything. The big problem with hookah bars and hookah parties is that people just suck on it all night, and take in an enormous amount of nicotine, much more than smoking a cigarette. But in your case, I assume you don't intend to smoke it again. If you were in fact addicted, you would be sweating bullets right now with your whole system telling you something is off -- like extreme disorientation, fatigue, nausea, headaches, the shakes, and the like. I'm addicted to benzos because doctors got me that way, and if I miss a dose I know it. My whole system goes haywire. So no, you're not addicted, and if this is the only thing you've ever worried about like this, learn from it and don't let stuff get to you like this the next time. But again, if this kind of thing happens to you regularly, you have an anxiety disorder and could use some therapy. Peace.
you tried it once and are afraid of addiction? i think you may have a fear of addiction itself and you should be fine. :)
