What is Kief?
Kief refers to the resinous trichomes of cannabis that may accumulate in containers or be sifted from loose, dry cannabis flowers with a mesh screen or sieve. Kief contains a much higher concentration of psychoactive cannabinoids, such as THC, than that of the cannabis flowers from which it is derived. Traditionally, kief has been pressed into cakes of hashish for convenience in storage but can be vaporized or smoked in either form.
Kief refers to the resin glands which contain the terpenes and cannabinoids that make cannabis so unique. While marijuana sans kief still contains cannabinoids, the resin glands that develop on flower buds pack the biggest punch.
