Hash comes from trichomes, the ripe, resinous gland heads that line the surface of cannabis plants. 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.
Hashish is produced practically everywhere in and around Afghanistan. The best kinds of Hash in Afghanistan originate from the Northern provinces between Hindu Kush and the Russian border (Balkh, Mazar-i-Sharif).
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.
