Hashish, or hash for short, is a preparation of marijuana made from the resin of the Cannabis sativa or Cannabis indica plant. The resin is dried into blocks of hashish, producing an oily, solid substance.Cannabis resin can be referred to by the names for the specific type of hash, rather than the generic names of hashish or pot. These different names for hashish include black, goldseal black, redseal black, and Morrocan (Rocky for short).Hashish is often warmed, crumbled, and rolled together with tobacco. It may also be smoked in a pipe, bong, or chillum. As with weed, hashish has a very distinctive, pungent odor. It is one of the easiest ways of identifying it as a form of marijuana. The appearance of hashish is so varied that novice users are often duped into buying licorice or other cheap, benign substances that look similar.
