Ok, short answer: A hookah is a traditional water pipe that comes from the Middle East/India and is designed for TOBACCO USE, despite the fact that a lot of people (especially younger people) who tend to think of it as drug paraphenalia Extended answer: To smoke it you place the hookah tobacco (sometimes referred to as shisha, but that name isnt entirely accurate if you want to get down to the nitty gritty) into the bowl, lightly sprinkled in, and with just a tiny bit of space for air between the top of he tobacco and the edge of the bowlThen you place a sheet of aluminum foil over the bowl, stretch it tight and proceed to poke small holes in the top to allow air flow (most people use toothpicks, i prefer a needle)Now you make sure there is water in the baseAll you need is enough to cover the bottom of the pipe by about an inch or soThen you place your hot coals on top of the foilLet it sit for 3-5 minutes then put the end of the hose to your mouth and inhaleYou do not need to hold the smoke in your lungs, infact i consider that to be quite foolishIt is necessary to rotate your coal around the edge of the bowl throughout the session to ensure that you are burning the tobacco evenly The session should last you around 45 minutes to an hour, and bear in mind that the primary reason to smoke hookah is flavorThere is a possibilty that you will receive a nicotine buzz, and to prevent you from getting sick from the smoke it is recommended that you have eaten fairly recently and stay well hydrated.
