Well i think In the US we are a little more paranoid about the government and people smelling it, and thus we want to be able to control when it burns, and that is easier to do with pipes and bongs, though i think we honestly all smoke bongs, blunts, bowls, and jays about equally at least i do, well probably more pipes cause im in the dorms and if you keep it next to a fan blowing out you cant even smell pot in the rooms at in the dorms
