Kief, also known as 'kif' in Morocco and Middle East, is the dried form of resin. Kief is produced by separating and sifting tiny crystals with resin glands from a cannabis plant. After drying, the residu containing psychoactive substances is often pressed into solid cakes.

Kief can also be obtained by using a mesh or sieve to collect the loose, dry cannabis flower parts fallen from a plant.
