depends on the quality, 4 good hits through a bong and i usually am feeling pretty good. 5 or 6 hits on a joint i get a nice buzz, but takes me about a half a joint to get a great buzz going.

or one hit on the hooka we had. loaded a whole 8th in the bowl, and 2 people pulling on it, it was gone in 8 pulls. that was a good night. but that 8th wasburnt up in 5 mins....
