Trichomes, the ripe, resinous gland heads that line the surface of cannabis plants, are the source of hash. Processes for separating resin have been used for years, but the fast development of cannabis legalization in the Western world has ushered in new hash preparation processes that are taking the legal market by storm.
The term “hashish” comes from the Arabic language and means “grass” in English. Although some say that procedures such as charas, or the collecting of resin from the hands of cannabis growers, existed prior to written history, it is thought that the popularization of hash began about AD 900.
Hashish first appeared in the Western world around the start of the nineteenth century as a result of early European expedition into Africa. For years, European doctors imported hashish to conduct research, which led to the development of various extraction processes and the incorporation of hashish into medicines.
