Okay , how to start over today topic ? Urrrmmm . okay let start like this . Well , everybody known about existing of sheeshaa (shisha) . i started shisha when i was 17 it has been only 2 years I've been smoking shisha but shisha has been one of my hobby and something that can helps me release my stress and I agree that shisha has more nicotine than cigarettes but that is just because it burns for longer and you overall inhale more smoke, and yes the nicotine is not water soluble but the tar in fact is, which is the most harmful part of cigarettes, also tar is a chemical reaction from biological substsances being burned, were in fact shisha is not burned it is heated and vapourized so therefore the chemical reaction never in fact occurs and any tar that may be created is than filtered out through the water. I smoke shisha frequently and agree it is bad for you but i dont think you should compare it to cigarettes because they are not completely similar. if you dried shisha and rolled it in rolling papers and smoked it it would than be worse for you than cigarettes but that is not how you smoke it. but indeed the coal is very bad for you and is indeed the most harmful part of smoking shisha. and yes shisha will inevitably cause cancer but smoking anything can cause cancer because lungs do not react well with smoke, if you rolled lettuce and smoked it that would put more tar in your lungs than smoking shisha.
