Hashish, also referred to simply as “hash,” is a cannabis concentrate that’s typically inhaled or smoked. Hashish can be made using a few different methods, but the essential steps are removing the trichome glands from a cannabis plant and repeatedly compressing the resin to form a hardened, solid piece. It’s arguably one of the oldest types of cannabis concentrates, with written texts referring to Hashish dating as far back as the 12th and 13th centuries. The varietable look and feel of Hashish is closely tied to its history and the method used to make it.
Sieved Hashish, originating from the Middle East and Central Asia, is made from resin powder that’s been collected from harvested and cured cannabis. Modern methods use fine mesh or silk fabrics to physically sift and separate the trichomes from the plant material. The mesh or fabrics used for sifting have varying pore sizes to help refine and purify the trichomes. The resulting powder, or kief, is then pressed and prepared as Hashish slabs or bricks, which can have a flat, hard, or sometimes chalky appearance.
