Incidentally, the only black market dealer in boulder I've found has high grade medicine for $160/half ounce. That's $320 an ounce assuming he cuts you no break and I haven't been to or heard of any dispensaries in Boulder selling it for that cheap. And he doesn't even grow it. How is it that it's so much more expensive for those producers who have to deal with less interference from law enforcement, and who have much larger customer bases?
