Hash

Hash is the umbrella term for concentrated cannabis products made by separating resinous trichomes from plant material and consolidating them into a homogeneous mass. Potency typically runs 40–80% THC, depending on the grade and starting material. The word is a 1590s English shortening of "hashish," itself derived from the Arabic ḥashīsh ("powdered hemp" or "dry herb"); the first recorded English use dates to 1598. The category includes traditional pressed hashish, bubble hash (ice water hash), dry sift hash, and hash rosin. The UN Single Convention on Narcotic Drugs (1961) defines hashish as "the separated resin, whether crude or purified, obtained from the cannabis plant," and many national controlled-substance statutes inherit this definition. Hash predates modern solvent extraction by centuries and is often framed as the original cannabis concentrate — a mechanically separated, minimally processed product whose quality is judged on color, aroma, malleability, and melt behavior rather than on a pure potency number. → See also: Hashish, Bubble hash, Dry sift, Ice water hash, Concentrate
