Kief is the cannabis flower’s most potent part, containing a high concentration of cannabinoids and terpenes in its tiny, sticky crystals. Also called “dry sift” or “pollen,” It refers to the flower’s trichomes’ resin glands. Because it is the most highly concentrated portion of the cannabis plant, it typically produces a much more potent high. In short, a little bit of it goes a long way. Smell and colour can vary a bit from batch to batch based on the kief origin strains.
