Yep, smoke pot outa a hook apipe with some shisha before. You just gotta be careful it dosent burm as it is in there for such a long time. and obviously watch the dosage etc. The taste is a bit weird to. hey, you might as well smoke a joint. But the experience is worth it.
I've done it before. Got VERY wasted. Its best if you get the coals burning well first with some of the special tobacco they use, then mix ur weed in with the wet baccy after that.
