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, Pakistan, and Afghanistan
are the main sources of hashish. The THC content
of hashish that reached the United States, where
demand is limited, averaged about 5 percent in
the 1990s.

Hashish has an average of 2 to 8 percent THC
and can contain as much as 20 percent THC.
