1911 Encyclopædia Britannica/Hashish

HASHISH, or Hasheesh, the Arabic name, meaning literally “dried herb,” for the various preparations of the Indian hemp plant (Cannabis indica), used as a narcotic or intoxicant in the East, and either smoked, chewed or drunk (see Hemp and Bhang). From the Arabic hashīshīn, i.e. “hemp-eaters,” comes the English “assassin” (see Assassin).
