Hashish (from Arabic: حشيش ḥashīsh, lit. grass; also hash or many slang terms) is a preparation of cannabis composed of the compressed trichomes collected from the Cannabis plant. It contains the same active ingredients as cannabis (but in higher concentrations) and produces the same psychoactive effects. Hashish is solid, of varying hardness and pliability, soften under heat. Its colour can vary from green, black, reddish brown, or most commonly light to dark brown. It is consumed in much the same way as Cannabis buds, often being smoked in joints mixed with tobacco or Cannabis buds, or in smoking pipes, or vapourized. It can also be eaten or used as an ingredient of food (baked into cookies or cakes, or added to stews and chocolate).
