SOLVENTLESS (aka NON-SOLVENT) CONCENTRATES EXPLAINED
These are extracts or concentrates produced without the use of a solvent, sometimes referred to as mechanical extraction, including hash, dry sift, bubble hash, and rosin. These are often broken up and smoked alone or added to flower prior to smoking.
Bubble Hash, also known as Water Hash, is a cannabis concentrate made up of countless trichomes, or resinous glands, that have been separated from the plant using ice water, agitation, and micro screens. Because big quantities of pure resin can be removed from the plant material, water ice water separation is a cleaner method that doesn’t involve other solvents and allows for a more refined hashish. Bubble Hash gets its name from the way that it bubbles when exposed to flame.
Hash, also called hashish and hash oil, refers to substances made from the compressed kief of the cannabis plant. Hash is usually formed and pressed into a block or ball of hard or doughy resin, while hash oil is the liquid accumulated from the trichomes. Both hash and hash oil may contain small pieces of the cannabis plant. Hash and hash oil are normally consumed orally or smoked. The higher concentrations of cannabinoids in hash make it far more potent than other forms of cannabis known to contain a 50 to 70 percent concentration level of THC.
Kief is the accumulated trichomes, or resin glands, that have been separated from the rest of the cannabis flower by sifting through a fine mesh screen. Since trichomes are the sticky crystals that contain the vast majority of the plant’s cannabinoids, kief is known to be extremely potent. Once isolated, it can be pressed into hash, used as an ingredient to infuse food, or to top off joints and blunts.
Shatter is the common name applied to butane hash oil (BHO), CO2 oil, or other cannabis-based extracts. It is created through an extraction process that eliminates fats and lipids and is believed to be one of the purest and most potent types of marijuana products. Shatter is typically transparent with a glass-like appearance and easily breaks into fragments when cold. The colors of shatter can vary depending on solvent, extraction method, age of the product extracted, and so forth. These products are highly potent, containing 60-85% tetrahydrocannabinol (THC) levels.
