you could look on google or yahoo questions, I mean I have a bar down here in KY that does some weed and stuff, I mean you could look for some reviews man.
You are supposed to inhale. That's the whole point. And yeah God is right. Don't do tricks. You will looks stupid if you don't know how. And if you get light headed then just pass the hookah and wait till it goes away. I haven't got buzzed off of hookah in ages. I remember when I did. It was a nice feeling.
