it is one of those funny things. It isn't hard to smoke slow it's just counter intuitive. And when I say slow I really mean how hard and fast I draw on the pipe not frequency of puffs. You can keep a pipe pretty cool drawing nearly constantly on it if you barely try and pull any smoke into your mouth. I think the great lesson here is breath smoking. Not so much that it's the best way to smoke (it is for some) but the fact it works at all really shows how little force is needed to work a pipe.
