I prefer glass, you can recylcle the oil, so when I'm dry and desperate there is always hope haha. I took some over to Portugal once on holiday, didn't take anything to smoke it with, I mean surely I'd get a bong over there, but no! Couldn't find anything and I can't do spliffs, so I made one out of an oxo box and some kitkat foil, did the trick nicely 8-)
