Kief is a powerfully concentrated extract which derives from the fine powder made from dried resin glands found on the leaves of the cannabis plant. Kief is effectively made by removing the trichomes from the cannabis flowers. Trichomes are the shiny, crystal-like balls that form on the leaves of the cannabis plant, and these crystals contain the highest concentration of cannabinoids compared to any other part of the cannabis plant. By removing these glands from the actual plant material, what you are left with is much stronger than buds. It also contains a high concentration of THC, the psychoactive chemical that causes euphoric feelings or opium-like high that can last for hours.
