Hash / Hashish Information

What is Hashish?

Hashish consists of the THC-rich resinous material of the cannabis plant, which is collected, dried, and then compressed into a variety of forms, such as balls, cakes, or cookie-like sheets.

Pieces are then broken off, placed in pipes and smoked. The Middle East, North Africa, and Pakistan/Afghanistan are the main sources of hashish. The THC content of hashish that reaches the United States, where demand is limited, averaged 6 percent in the 1990s. Hash is sold in solid pieces ranging in colour from light brown to black; in texture from dry to soft and crumbly. It can also be baked into cookies or cakes.
