I'd smoke resin before toking on some of that Molded Mexican Schwag we sometimes get around here. I have been desperate a few times in the past and smoked some 3-4 month old glass pipe resin, its not bad just taste like old stale nasty bong hits. The shit that builds up in a water bong is just fucking nasty though, would never smoke that shite. I usually never touch the stuff unless I'm cleaning it outta my bongs. Once it gets on your fingers the smells sticks to them for days, unless you rub it off on a solvent soaked rag.
