i've heard that smoking burns your lungs and leaves tar in them. the bong water takes out lots of tar, which is why i tturns that color, but that tar has thc so you have to inhale more of it. so it evens out. but the water cools the smoke, it doesnt take chemicals out, but by cooling it, you dont burn your lungs as bad. hope that helps:hippy:
stonerman07 Reviewed by stonerman07 on . can large bong hits give u lung problems? I have heard that taking really large bong hits/holding in hits for a long time can give a person a collapsed lung and other problems. Is this true, and are hits from the bong bad for your health? Rating: 5
