I've heard a few people sing their praises, and a few say that they're not worth it. Some cost $80, some are $400, but I don't really know what makes one better than the other, or either of them better than a $20 glass pipe.
Sometimes if I'm smoking every day I'll develop a cough, so I'm guessing that it's not that great for my lungs. Would a vaporizer be better?
they sell a fancy little induction heater for them. my friend used to have one it actually gets you blasted, insanely efficient way of using green.
