Kief (from Arabic كيف kīf, "Joy, pleasure"[1][2]), sometimes transliterated as keef, also known as "Dust" and "Chief" a.k.a cannabis crystals among other names, refers to the pure and clean collection of loose cannabis trichomes, which are accumulated by being sifted from cannabis flowers or buds with a mesh screen or sieve.
Traditionally, kief has been pressed into cakes of hashish for convenience in storage, although it can be vaporized or smoked in either form.
In Morocco, kief also refers to a traditional mix of finely-chopped cannabis and indigenous tobacco, which is distinctly different from trichome powder.
[4] In other countries, such as the US and those of Western Europe, kief is used to make products via infusions.
Due to its potency, however, some users consume only a small quantity of kief in order to limit its effects.
