in some states (illinois, or at least where I live in illinois) its illegal to sell bongs, pretty mucha nything with a pull choke. they can have bubblers (pretty much a bong with no pull) and bongs with carb holes, but bongs are illegal to buy here. just recently though, i guess they figured they found a way around the law and are now selling bongs without the stem or the bowl in them and its just a hole and they call it a "vase" but if you ask about stems and bowls, they direct you to the back where they hold all the glass.
