I smoked it for an hour my first time with a friend at an Indian restaurant around where I live and ended up puking my guts out. It was after i finished my meal when I started to feel sick. I put the money down for the food, tipped the guy who set up my hookah, walked outside and puked lol. We drove to my friends house and I puked in his sink. I then drove home and had to pull over and puke on the way there. Hookah is very fun to do...just dont over do it when you begin smoking it.
