Well... it can be done, but the result is nasty. The hash oil you can get from this is weak, and full of all the bad substances (many of them are carcinogenic) that exist in the resin of burnt weed. And it tastes awful too. Sincerely, i dont recommend it. If you want make hash oil, make it from weed, kief or trim, cause the resulting product is WAYY more enjoyable. :stoned:
