herbaholic makes a very good point: typically hash and brick ARE shit, poisonous, and bad to get high with. but Lonerstoner was referring to the resin from your own pipe...

I have also had many a time when the pipe cleaning was simply to get at the gooey sticky resin inside...I once bought a chambered pipe with a bunch of extensions so I would have about 2 feet of tubing to scrape clean (it took a helluva long time, but I was burning blades for the rest of the weekend with what I got!)

hash and resin are completely different things...resin is simply condensed smoke from whatever you were burning in the pipe. Hash is mass-produced shitbricks that will probably kill you quickly.
