ˈkēf | Noun


An accumulation of trichome glands sifted from cannabis flowers with a mesh screen or sieve. Kief is the most potent part of the plant in terms of cannabinoids with a high concentration of tetrahydrocannabinolic acid (THCA). Kief can be pressed into hash, used as an ingredient to infuse food or to top off joints and blunts.


“He sprinkled some kief on top of the joint to give it an extra kick.”


“The grinder came equipped with a kief catcher.”

What is Kief?

Kief is made by separating the trichomes, which contain the plant’s cannabinoids and terpenes, from the rest of the cannabis flower.

Because kief is more potent than cannabis flower, less is needed in order to feel the desired effects.

How to Collect Kief

Kief is also the name for the trichome glands that collect at the bottom of your grinder, and grinding your flower is the easiest way to make kief at home.


Many grinders come with a kief catcher, a compartment on the bottom of the grinder that uses a screen to catch the trichomes as you grind your cannabis flower. As you grind your flower, the trichomes will sift through the screen and collect in the kief catcher. Once you’ve accumulated a decent amount of kief, you can remove it with a scraper.


If you’re looking to process large quantities of kief at home, you can purchase a “kief box,” which typically has two chambers — one for sifting cannabis flower and the other for catching kief. Put your cannabis into the chamber, close the box and shake. As you shake the flower, the trichomes fall off, get sifted through the mesh screen, and end up in the kief chamber.  On a commercial level, cannabis is sieved in a vibratory sifter over a series of screens to create dry sift.

How to Use Kief

Sprinkle kief on top of a bowl, joint, blunt — or in a hookah

Sprinkling a generous dusting of kief to the top of a packed bowl, joint, or blunt can dramatically increase the potency, making for a more intense and longer-lasting high. Kief will also burn slowly, extending the time it takes to smoke — perfect if you enjoy long smoke sessions with friends. If you’re a fan of smoking shisha out of a hookah, you can sprinkle kief on top of the tobacco before adding the hot coals.

Make ‘moonrocks’ with kief

Kief can also be used to make what are known as “moonrocks.” To create moonrocks, high-quality cannabis flowers are covered in hot oil and sprinkled with kief. Once the rocks harden, they can be broken up and smoked, delivering a potent high.

Add kief to tea or coffee

Heat can activate cannabinoids, so adding kief to a hot beverage such as like coffee or tea can produce similar effects to eating an edible.

Press kief into hash and dab it

Kief is easily used to make hash. All it needs is heat and pressure.


Add kief to the center of a piece of parchment paper. Fold the paper tightly around the kief, and then apply heat and pressure. Typically the heat from your hand should be enough, but you can also use a hair straightener or a temperature-controlled press.
