Anyone ever smoke out of a lung (waterless gravity bong) Its just like a gravity bong except instead of using water you put a bag inside of it and seal it around the bottom. Then when you pull the bag down out of the bottle it does the same thing as when you pull the gravity bong out of the water. They fucking rock your face off. Rating: 5
