Hash from Morocco and Lebanon are made by sifting mature cannabis flowers through a series of sieves until only a resinous powder remains. This powder is compressed and heated to allow the resins to melt and stick together forming blocks. The resin is then compressed into blocks and sealed with cellophane or cloth. The result is a hard, brittle hash, usually light yellow to brown and sometimes even reddish brown. Generally, the really hard and yellow stuff which is cerebral is old Lebanese on the whole, and the slightly darker brown hash is usually Moroccan. Apparently, new Lebanese is often also malleable. The method used in Southern Asia involves rubbing the living flowers of the cannabis plants with hands, a leather apron or other implements. The aim is to get the soft and sticky resins to stick to a surface which can be taken somewhere to be processed and collated. These are then scraped off the skin or leather and rolled into lumps of various sizes and compressed into blocks. The color is usually dark-brown to black on the surface and lighter on the interior - air contact makes this hash go darker in color.
