Hash is basically the word hashish. Like the marijuana has a very old story. It is said that the plant originated in the Hindu Kush. More reliably, it may have originated in northern India, which also has a long social tradition in the production of hashish, which is locally known as Charas. Hash is usually produced in warm environment. It is usually found in a belt extending from North Africa, Egypt to Northern India and central Asia. The primary hash producing countries are India, Afghanistan, Pakistan, Nepal, Morocco, Lebanon and Egypt in that order. Hashish is also produced now in the desert in northern Mexico, however, demand and production are both insignificant compared to those of "fresh" Mexican marijuana, especially in the lucrative U.S. market.

Hash is made from cannabinoids-rich glandular hairs known as trichomes, as well as varying amounts of Cannabis flower and leaf fragments. The flowers of a mature female plant contain the most trichomes, though trichomes are found on other parts of the plant. The plants may be sifted by hand or in motorized tumblers. Finger hash is formed by rolling the ripe trichome-covered flowers of the plant between the fingers and collecting the resin that sticks to the fingers. The ice water separation is a more modern mechanical technique which submerges the plant in ice and water and stirs the mixture. Trichomes are broken off the plant as the ice moves, and the low temperature makes the trichomes brittle they disconnect easily. Chemical separation methods generally use a solvent to dissolve the desirable resins in the plant, while not dissolving undesirable components. The product of chemical separations is more commonly referred to as honey oil, hash oil, or just oil.

Small pieces of leaf stuff or even purposefully added adulterants introduced when the hash is being produced will reduce the purity of the material. THC content of hashish usually ranges from 15-20% and that of hash oil from 30-40%. Fresh hashish of good quality is soft and pliable and becomes progressively more difficult and less potent as it oxidizes.

Just as marijuana, hashish is usually smoked or eaten. Hashish is stimulating and can produce excitement and other feelings similar tomarijuana, but the effect is stronger. Hashish is an illegal substance throughout the world with no accepted medical use. As with marijuana, the primary active ingredient in hashish is delta-9-tetrahydrocannabinol (THC).
