Lighten up guys, it's not like he's down on all fours picking at the carpet for dropped pieces of rock. I for one have done some radical things to get high including cleaning pipes of their resin and smoking it, hell I even drank bong water once but I'm not some crazed fiend. There are times when my guy runs out and I just simply want to get stoned. That is all. It is un-healthy though, can't deny that.
Are you wondering how to efficiently clean out a pipe so you're left over with usable resin? If so what I usually do is take all my pieces, (pipes, bong stems etc..) as well as stems I've collected and throw them in a zip-lock bag filled with isopropyl alcohol (99% only!). Let it sit for a couple hours (the longer the better actually) shaking it around every once in a while. It should turn a dark dark brown. Pour it into a Pyrex bowl and set it on top of a pot of water making sure it forms an airtight seal. Set the burner to a very low heat and wait... The isopropyl will evaporate and you will be left with dark sticky tar in the bottom of the bowl. To make sure all the iso has dissolved, scoop up a bit of the resin and take a lighter to it. If it flares up at all, then there is still alcohol in the bowl. Now you can smoke this stuff (preferably with blades) or just roll it up into little balls and swallow it. What we did once is roll up a bunch of little balls of it, toss it in a cookie dough and bake. You don't even really taste it and it works just as good as actual pot baked goods
A couple things to make sure of though. Make sure you DO NOT just try to boil a pot of isopropyl directly on the burner, that shit is EXTREMELY flammable.Use the ghetto double boiler method I mentioned. Also make sure you do it in a well ventilated area, the smell of the iso is very strong.
If you already knew this, I'm sorry
