I scrape the resin out of my one hitter, since it gets clogged up pretty quickly. I tried to scrape resin out of a little glass spoon, but it was powdery (like black dust) and didn't work all that well. The weed at the end of a joint gets very resinated, though; if you put out your roaches and save them, you can pack the resin-weed into a piece (or use it to start your next j), and it's quite potent.
