Re: good or bad?
I don't know about which is worse chemically. Although I assume cigarettes considering th list of additives, most of which are considered poisonous on their own or are classified as hazardous waste. Hookah has tobacco, honey, glycerin, molasses and some flavoring... pass me the hose please.
But I do know that hookah is less habit forming. It is far easier to pull out a cigarette and light up than it is to set up a hookah and start smoking. Cigarettes have almost no limiting factor like that.
