Where do Concentrates come from? The cannabis plant is covered in trichomes, resinous glands that contain cannabinoids, terpenes, and other compounds. Trichomes can be extracted from the cannabis plant, creating a concentrated form of cannabis. These concentrates can take on numerous forms, largely depending on the method used to create them. How are Concentrates made? Some common methods include: water extraction (ice water hash or bubble hash), heat and pressure extraction (rosin and hand hash), chemical extraction (CO2, butane, pentane, hexane), and dry sieve hash/kief. Chemical extraction in particular produces a wide variety of consistencies, with concentrates coming in forms such as glass, shatter, budder, taffy, and oils. How to use/smoke Concentrates: Most concentrates are dabbed, or flash vaporized, through a dab rig, but some concentrates can also be added to the top of a bowl of flower, or used to make edibles.
