Keif

Keif, commonly spelled kief, refers to the collected resinous trichomes of cannabis flowers. Trichomes are the tiny glandular structures on cannabis buds that produce cannabinoids, terpenes, and resin. Keif is the fine, powdery material that loosens from the plant during grinding, sieving, or sifting, and it is typically richer in cannabinoids and terpenes than the surrounding plant material.

Composition and potency

Keif contains concentrated cannabinoids, primarily THCA and CBDA in raw form, which convert to THC and CBD with decarboxylation. It also carries a mix of terpenes that contribute aroma and flavor. Potency can vary widely depending on strain, growing conditions, and processing.

Collection and forms

Keif is often collected in cannabis grinders, from dried flowers, or through dry-sifting over screens. It may be referred to as powder, pollen, or pollen dust in some contexts. Once collected, keif can be used in various ways: sprinkled onto bowls or joints to increase potency, pressed with heat and pressure to form hash, or incorporated into edible preparations after decarboxylation in some cases.

Legal and safety considerations

Legal status of keif varies by jurisdiction and is tied to broader cannabis regulations. Because keif concentrates cannabinoids, its effects are typically stronger than those of ordinary cannabis flower, which can increase the risk of adverse effects for inexperienced users. Proper storage is advised to preserve volatile terpenes, and contamination with mold or plant debris should be avoided.

Name and etymology

The term kief derives from Arabic kayf, related to pleasure or intoxication, and is widely used in cannabis culture. In some contexts, terms such as pollen are also used to describe the same resinous material.
