hashish (hăshˈēsh, –ĭsh) [key], resin extracted from the flower clusters and top leaves of the hemp plant, Cannabis sativa, and C. indica. Hashish, called charas in India, is the most potent grade of cannabis and is obtained from cultivated plants grown in hot, moist climates. Marijuana, a cheaper and less potent substance, is usually obtained from the cut tops of plants grown in cooler climates. Like marijuana, hashish is usually smoked, but in a pipe or water pipe; in N Africa it is also eaten. Hash oil is an extract of hashish that can be smoked or added to the tobacco in a cigarette. Hashish is an intoxicant, producing euphoria and exaggerations of sensations. It is an illegal substance in the United States with no accepted medical use. Like marijuana, its active ingredient is delta-9-tetrahydrocannabinol (THC).
