How to smoke with less cough?

[Markass]

I always thought hot water was great too, amazingly smooth hits, until we filled our bong up with that really hot water gas stations use for coffee... it cracked the bong immediatley

gotta gradually work it into hot water from cold..just as you've got to gradually go to cold from hot..otherwise that happens to you. learned my lesson once...$50 and a new bong later..
