I really want to go to a hookah lounge for the first time. I just know, beyond all doubt, that I'd totally love the groovy vibe there. And I understand exactly what hookah is but I have one big question: Do you inhale the smoke or just swish it around in your mouth? Surely, hookahs aren't filtered, right? Can someone clue me in before I make a coughing, gagging fool of myself?
