It is usually smoked in a pipe or in hand-rolled cigarettes. Hashish (hash) is a dried-caked resin from the flowers and leaves of the plant. It is sold in chunks and cubes, and its color range from light brown to black. Hashish is often blended with tobacco and smoked. It is more potent than marijuana because it contains a higher concentration THC (abbreviation for delta-nine-tetrahydrocannabinol). THC is the main psychoactive ingredient in all cannabis preparations (NIH). The more THC cannabis contains, the stronger it is.
