never. not even to save my life. however, this does not mean resin is worthless. for anyone who has ever made hash using isopropyl alcohol, i suggest you try adding resin to your next extraction. it will increase the overall amount of thc in the product and, more importantly, change the consistency of the hash from super-glue-like tar to a less sticky, wax-like hash which is much easier/pleasurable to collect, store, break-up and (drum roll please)... smoke. yes, it will make your homemade hash smoke very nicely and will also help to keep it from sticking to your fingers, thus decreasing waste. so instead of smoking plain resin, try making hash with it.
