raditional hash is made by shaking the flowers (buds), which then drops the resin glands onto silk screens. The resin glands are then sieved through the screens to create kief. The kief is then normally compressed to form a block of hash. While some dispensaries in Colorado sell both traditional hash as well as kief, you are more likely to encounter kief. The only real difference between the two is that hash has been compressed, while kief has a loose, powdery consistency.
