Hash is generally more potent than other kinds of marijuana products are. This means consumers can ingest less of it while still enjoying an intense experience. When kief is heated and pressurized, the resin glands within it rupture, causing the kief to undergo changes in color, taste and effects. The more highly pressurized kief is, the darker the subsequent hash becomes.  While kief hasn’t undergone the same mainstream popularity as other marijuana products, it’s still one of the most effective and affordable forms of marijuana in the world, making it a good choice for cannabis consumers everywhere.  Sold by the gram.
