Yeah they burn a bitch load of weed. As long as you're not supplying it's all good. I had a one person hookah and it wasted more weed than a blunt. I can't imagine the size a bowl would need to be for a 4 person hookah. I don't like tobacco so I'd say no but if you like tobacco I imagine it would save you alot of bud. Have fun they're a pretty sweet way to smoke but it does waste money like madthough.
