Hashish, hash for short, is derived from the “kief,” or the dried resin, of the flowering tops of mature and unpollinated female cannabis plants. The resin glands are called trichomes or crystals. Hash is harvested by collecting the powdery resin either by hand, by mechanical beating of the plants, or by submersing cannabis plants in icy water and then using small sieves to remove the trichomes, which are then dried (this type of hashish is called “bubble hash”). The remaining kief is typically pressed into “cakes,” or blocks, which are then smoked in pipes, vaporized and inhaled, or mixed with marijuana in joints.
Hash can be soft and pliable or stiff and brittle. It may be red, black, brown, green, yellow, or blonde in color. Hash may also be used in cooking, as it is soluble in things like oils, butter, or cream and can therefore be made into foods like brownies. Hashish may also be further manufactured, and the resin extracted and made into hash oil, a gooey substance that individuals are “dabbing” and smoking with e-cigarettes.
Today, there are many forms hash can take, and while the process of creating hashish has evolved significantly, the desired active ingredient has remained the same. These oils and hash itself are both made to contain high amounts of active marijuana ingredient, yet there is a difference in appearance and how they’re extracted. Although commonly encompassed as another nickname for cannabis, hash is very rich in history, and should be distinguished from more recent forms.
