Haha, some of you totally crave nicotine and just don't realize it. I'm sure you all really do love setting up and smoking your hookahs, but there's a chemical thing going on inside of you, too.
There's no real comparison between hookah and cigarettes, though. Cigarettes give you on-the-go fixes and forms habits extremely quickly. I go off and on them - smoke one month, don't smoke the next. One gets so used to taking a break from work and having a cigarette, getting off your shift and having a cigarette, smoking a cigarette in the car, etc.
I've stopped smoking cigarettes for quite awhile now, but I do notice that if I've smoked hookah for a few days in a row, on that fourth day I will have a slight craving for some smoke.
