I've rinsed the same bud and made hash oil with it a few times to see how much useful oil I can get from some bud. The first time was a beautifully pure brown oil. Second time was a little darker but still excellent. This third time the solution was very dark green... now that it's fully dried it's still very sticky and very black/dark green. The part that worries me is it smells very acrid and sour, very much like strong vinegar. Is this just a crapload of chlorophyl breaking down? I'd like to smoke it but I'm half worried about the results. I always use the Iso-method rather than butane. Any input would be appreciated, especially from you Fdd2blk... you tend to be the hash king.
