Yo, hash is not green. The darker it is, typically it will be better. Jet black hash however is either way too potent for most people, or it's not hash anyway. Hash is a tough thing to come by in the states but I can vouch for a few European countries like France and Italy. This summer I had the pleasure of sampling many kinds of hash from both countries in numerous cities. Overall what I noticed was that the best product was coming from organized dealers who had a safe spot to buy/sell. Second, the best hash was very dark but still brown. Third, you should never pay more than 25 dollars a gram (about the size of two sugar cubes stuck together). Hash is certainly something to try if you are into cannabis. Good luck on your search and happy toking!
