smoke it, doesn't matter what it taste like. resin is nasty no matter how new or 'pure' it is, all resin is, is the tar/buildup from smoking... if you ain't got nothing else and don't have hope of getting any real weed/bud, then smoke it, what can it possibly hurt? i recently obtained a new bong from someone who hadn't smoked in months, i was dry at the time, i scraped it all (including my pipes) and still got high, i'm pretty sure resin doesn't have a fast-paced degredation process, meaning, if you resinated your pipe with one batch of weed, way later on, even tho the weed you resinated it with would be bad, the resin would still get you high...

back to my original post, what can it hurt?
