Medical marijuana patients have been getting screwed by lawmakers and lobbyists for almost a decade now, but at least they still have Allgreens. The medical-only dispensary in south Denver sells $6 grams of shatter, as well as rosin capable of standing up to the other hash lords of Colorado, but at a much lower price. Even Allgreens' private reserve costs less than $30 per gram, and the in-house full-melt live heads and 4-gram buckets of rosin are the most affordably priced fire in town. You might find something cheaper or a brand with more hype, but nothing beats the value of Allgreens extractions.
