The word `kif` is derived from Arabic `kayf`meaning well-being or pleasure. Kief, keef or keif is a fine powder made from dried resin glands (trichomes) that are found on the leaves of the cannabis plant. It contains a high concentration of the psychoactive chemical or THC that causes euphoric feelings or opium-like high that can last for hours. Kief is also called crystal or pollen. The quality of kief depends on the quality of marijuana plant.
Kief can be collected in several ways, if larger amounts are needed then it is collected by rubbing leaves over stainless steel mesh screens or by shaking the branches and holding something under the plant. There is a special machine designed for processing larger amounts of leaves where they tumble against a rotating silk drum and glands fall off. For less amounts of kief one can use a herb grinder with a special bottom compartment for collecting kief. This device is called a kief catcher and it is usually a screen. The kief catcher is a useful part of every type of grinder as without it kief is just wasted. If you break marijuana using your hands, then all the kief will stick to your hands and you will lose it.
You can also try shaking or banging the grinder while marijuana is in the grinded section. That way some extra kief will fall into the bottom compartment.
What To Do With Kief
Kief can be smoked straight rolled in a joint or from a bowl and just remember it will burn up quickly. Most people just sprinkle some kief over their marijuana and roll it or mix it with tobacco. Kief is used for making hash which means pressing kief into little bricks, baking them, pressing again and then let them cool and dry. Then use this for smoking. You can make THC infusions (i.e., butter or oil) and use it for baking cookies, brownies or any food that is cooked with butter or oil. Keif is very potent so you will only need a small amount to get high. The kief seems to smoke best when put on top or in between another medium.
