I'm really short on cash and i was thinking about buying one of these small metal pipes, are they worth it?
I think those are used for fairly short term or else they start to burn and become harmful... I'm not sure, though. I was able to buy a small, glass one hitter for 5 dollars at my local shop that had been put to great use!
Those are great bowls... and they do get hot.... but only if your hittin it with a lighter for the entire hit, it's best to let them cherry. Buy one and save your self from the risks of making a homemade piece.
