Keif can be made a few different ways but the most common is through the use of a grinder.ou Many marijuana grinders come with a screen at the bottom of them to catch all the keif that falls off the buds when you grind it up. Keif is basically the trichomes that break and then fall off of the bud. Keif is both stony and tasty.
Kief, Ageef, Ageeve refers to the loose, dried resin glands (or trichomes) of cannabis which may accumulate on containers, in grinders, or be removed with a kiefing screen or sieve. The word is similar to the Arabic word “كيف” which literally means “how”. Informally, in the Egyptian dialect it means “being buzzed” or “liking to get high”. It is sometimes erroneously called pollen or crystal. Kief can be smoked in a number of ways, including using narrow (5-mm.) screened smoking pipes, Waterpipe (bong), in a vaporizer or rolling papers (resulting in a joint). Kief contains a much higher concentration of desired psychoactive ingredients, primarily THC, than ordinary preparations of cannabis buds from which it is derived. en.wikipedia.org
