Hashish, often simply called hash, is a cannabis concentrate made from the resin of the cannabis plant. The resin glands, known as trichomes, are collected and compressed into a variety of forms, such as blocks, cakes, or balls. Hashish can vary in color from light yellow to dark brown, depending on factors like the origin of the cannabis plant and the processing method used.

People consume hashish by smoking, vaporizing, or ingesting it. When smoked or vaporized, it produces a potent high due to its high concentration of cannabinoids, particularly THC (tetrahydrocannabinol). The effects of hashish can be more intense and long-lasting compared to smoking dried cannabis flowers.

In terms of legality, the status of hashish varies by location. In some places, it is considered illegal and classified as a controlled substance due to its THC content. In other areas, especially where cannabis laws are more permissive or where medical cannabis is legal, hashish may be available for medical or recreational use.
