> it's totally good to breathe smoke you never want to breathe hot smoke you puff. hot smoke breaks down the elasticity of the sacs in your lungs, they crack, and get infected (emphysema) drag a little from the cig only into your mouth, then inhale cool air through, which lowers the temp and dilutes the smoke before it goes into your lungs.  a water bong reduces the temp of weed smoke allowing potheads to take in smoke without destroying their lungs.  marijuana burns hotter than tobacco, and kills more people than tobacco. if you smoke weed (and i don't recommend it) use a damn bong.
