The plants which are used for Hash production are very small and bushy Indicas. In Afghanistan, Hashish is pressed by hand after the addition of a small quantity of tea or water. The Hashish is worked on until it becomes highly elastic and has a strong aromatic smell. In Afghanistan, the product is stored in the form of Hash-Balls (because a round ball has the least contact with air), however, before being shipped, the Hash is pressed tightly in 100g slabs generally. Good qualities of Afghani are signed with the stem of the producing family.

Hashish is the moment at which the essence of cannabis (the trichomes) parts ways with the plant material itself. This is achieved when the ripe and resinous gland heads that line the surface of female cannabis plants are separated and collected. Processes to achieve resin separation have been practiced for centuries; however, the rapid rise of cannabis legalization in the western world has brought new methods in hash preparation that are sweeping legal markets by storm.
