Some say that Asian are the ones to thank for the form of these water pipe ( marijuana bongs ).Some supposed that bongs are older than the waterpipes, ancestor of its Indian members. People ( particularly in amsterdam ) generaly use bongs to smoke what is called nowadays softdrugs which is know as : marijuana, marihuana, weed, pot, cannabis and other obscur local terms that I wont state here ;)

On top of every marijuana bong you'll find a bowl in which you place your smoking herbs. The smoke passes through the fluid ( usualy water ) previous to getting to the mouth. Some of carcinogens like tar are filtered by the water / fluid. The water also cools the smoke. Using marijuana bongs allow smoke to be inhaled alot more intensely and quickly. Results is augmented competence , thus less marijuana is wanted.

When smoking a marijuana bong don't use tobacco. Use clean marijuana. By not using tobacco you will only get unadulterated marijuana rudiments in your lungs creating a clearer feeling. Tobacco has opposite effect: mixing of tobacco with marijuana makes you dull and tired earlier. You also require smoking more to feel high-quality.
