Kief refers to the trichomes (the shiny, tiny “hairs”) on a bud of a flower, and is a powerful form of concentrated medical cannabis. It can be extracted directly from the bud, or sifted from loose cannabis flower, and is used to make Hash.
Kief is a very versatile form of concentrated medical marijuana. It can be smoked traditionally, infused into edibles with minimal impacts to flavor, or baked into bricks to form Hash, which can be smoked with a dab rig.
The appearance typically has a yellowish tint and looks similar to pollen. The THC content of Kief is largely dependent on the type of flower it came from, so it typically ranges from 20%-60%. Essentially, flower with higher a THC content would have Kief with higher THC content.
