To begin, yes...any form of smoking/tobacco isin't going to be good for you. I know there have been numerous studies regarding the health effects of hookah smoking, but sadly it hasn't been going on long enough in this country to warrant any real results. There is a common mis-conception that the water "filters" the smoke and "takes out all the bad stuff for you" which is total BS...it does nothing more than cool it.
Now, I am a hookah smoker, have been for a year or so now (I usually do it 2-3 times a week with 3-4 people). I have a feeling it is more of a fad thing for me to do in college, and most likely will not continue once I begin a "real life"
(along w/ other things :evil
. I guess I am mildly concerned if I am potentially causing myself more harm than it's worth in the long run. It's a great social activity, makes for great conversation (which I know can be said about anythng), and is just relaxing. *shrug* Guess I'm not sure what I'm asking, other than if anyone had any real info. on the matter 
edit: I never have, and never plan to smoke cigs...I've tried one before and cannot think of one thing that tastes worse than that crap
