Simply put, the difference between hash and weed and kief is kief is a name for a part of the cannabis plant, and hash, or more formally hashish, is a product made from cannabis and/or kief.

You might recognize kief as the sticky, glistening powder that coats your fingers, and grinder, after handling fresh flower. Kief is simply loose trichomes that have been separated from cannabis flower, usually as it's sifted through a series of mesh screens.

Kief is also sometimes called dry sift, in reference to one of the oldest and most reliable methods of concentrate production. Throughout history, cannabis cultivators and consumers would sift cannabis plant material in order to collect kief. Today, kief collection is simple and straightforward.


Using heat and pressure, kief can be transformed from a loose powder into a more compressed, potent cannabis concentrate known as hashish, or hash. It is a solid cannabis concentrate made up of compressed trichomes. Hashish roughly translates as “grass" in Arabic, and, like kief, it has been utilized both medicinally and recreationally throughout civilizations for centuries. Hash is considered one of the OG cannabis concentrates, boasting a rich history and esteemed reputation.

When trichomes in kief are pressed together, kief undergoes physical changes that impact its appearance, texture, color, taste, and potency, turning it into hash. Hash can be processed in a variety of ways, depending on where in the world it's being processed, leading to products that can vary in color, texture, and appearance. Hash can take on a waxy or liquid-like consistency, appearing as a brick, slab, or even ball of compressed kief. It can be green, brown, or a sandy color. Unlike kief, hash is likely to be more potent the darker it is in color.
