"Hookah" it's a shisha and that 200 fag thing is a complete myth; the smoke gets filtered through water so, while it's not exactly good for you, it's nowhere near the equivalent of 200 cigarettes in one session.
hookah and sheesha are the same thing, just depends where in the world you're from
Grew up in the middle-east and no-one calls it hookah man. Not even Indian people (they came up with the word), everyone just says shisha.
There's a large Middle Eastern population where I'm from and they predominately call it hookah. Definitely depends where you are.
