ghalyan (or ghelyoon)
According to Wiki according to a study according to students surveyed 40.3 percent of college students had smoked from a hookah. I suspect that is inflated, as some of the stoners likely hit the "yes" button several times expecting a candy bar to drop.
Someone I know, I am not going to say who, used to pack shaved ice from the freezer compartment into a clay pipe for a nice cool smoke. It still wrecked his lungs.
