i clean my pipe out and save that shit. when i got nothing to smoke, i smoke that. it gets you high a shit, but it also tastes like shit. it's nice when your out and you go "ahhaa! my ball of resin!" also you can boil glass peices. get a pan big enugh for the piece and wrap it in a sock or t-shirt, so it doesn't bang arround. boil it for a while and it will be store bought clean in no time. rubbing alcahol works to, but you gotta make sure it's damn dry before you toke again, or BOOM!.
