The term “marijuana extracts” basically refers to any product that is made by extracting desirable compounds (such as cannabinoids and terpenes) from the cannabis plant and combining them in a concentrated form. In cannabis, the compounds manufacturers are looking to extract are cannabinoids (such as THC, CBD, CBN, etc) and terpenes (such as pinene, limonene, etc). Cannabinoids are unique compounds that give cannabis its medicinal properties, while terpenes are mainly known for giving cannabis the aromas and tastes that we all treasure, although they also have medicinal properties of their own. By extracting and concentrating these compounds, manufacturers are all striving towards one common goal; to create a pure product with high concentrations of the chemicals that give cannabis its distinct effects. The process of extracting and concentrating these compounds, however, isn’t easy. The purity and quality of the end product is governed by countless variables, including everything from the chemical profile of the strain and the particular extraction method being used. •It’s All About The Trichomes All marijuana extracts are made by separating the trichomes (those sticky, hair-like crystals on your buds) from the plant matter. These trichomes contain the highest concentration of cannabinoids and terpenes in the cannabis plant, meaning they also harness the plant’s maximum medicinal potential. Many plants have trichomes, such as The Venus Fly Trap, which uses them to sense prey on the inside of it’s leaves, or the tomato plant, which uses them to sense predators, such as caterpillars. Scientists hypothesize that the trichomes found on cannabis work similarly, as a defense mechanism. •Different Forms of Cannabis Extraction There are a variety of ways to extract cannabinoids and terpenes from the cannabis plant. The various methods are usually categorized by whether or not they use a solvent to separate the trichomes from the plant matter: -Solventless Extraction Methods: Different Forms of Cannabis Extraction There are a variety of ways to extract cannabinoids and terpenes from the cannabis plant. The various methods are usually categorized by whether or not they use a solvent to separate the trichomes from the plant matter: Solventless Extraction Methods: Although the term “solventless” technically refers to a concentrate that is made using an extraction method that doesn’t rely on any kind of solvent, the term is generally used by the industry to refer to products that are made without the use of chemical solvents such as butane or alcohol. The most common solventless extraction methods include: Dry sifting: Literally sifting cannabis flowers through various sieves to separate the trichomes from the flower. Dry ice is often used to produce kief or hash. Cold water extraction: Cannabis plant matter is combined with ice and water and then agitated to separate the trichomes from the plant. The mixture is then filtered to remove the water and leave behind a relatively pure concentration of cannabinoids and terpenes. This method is used to produce ice-water hash. Heat and pressure extraction: Most commonly used to make rosin, this method uses heat and pressure to press cannabis flowers and extract a thick, golden oil that contains high concentrations of cannabinoids and terpenes. This method is used to create rosin. CO2 extraction: A complex extraction method that works by turning CO2 gas into a supercritical liquid and using that liquid as a solvent to extract the desired compounds from cannabis plant material. This method is used to create CO2 Oil. •Solvent-based Extraction Methods Technically, the term “solvent-based extract/extraction” refers to any product which is made using a solvent, in which case any marijuana extracts made using CO2 or water extraction methods would fall under this heading. However, the cannabis industry generally uses this term to refer to cannabis extracts made using chemical solvents such as butane and ethanol. The most common solvent-based extraction methods include: Butane extraction: As the name implies, this method uses butane as a solvent to extract the key cannabinoids and terpenes from plant material. This is usually done by packing cannabis plant matter into a container with a small opening and ‘blasting’ or pouring liquid butane over the flower to extract the good stuff from the plant. The resulting mixture is then heated to remove as much of the solvent as possible, resulting in a concentrate that is rich in cannabinoids and terpenes. This method is used to create a type of hash oil known as BHO (Butane Hash/Honey Oil) which is often referred to by names like Shatter, Crumble or Wax, depending on the consistency and appearance of the final product. Alcohol extraction: This method is similar to butane extraction, but uses alcohol (most commonly isopropyl alcohol or ethanol) as the solvent to extract the key compounds from the plant. Most commonly, plant material is soaked in alcohol for short amounts of time, before the mixture is filtered and occasionally heated in order to remove as much of the solvent as possible. This method is used to create tinctures and hash oil, the latter of which may be sold under a variety of names describing the texture of the oil or the alcohol it was made with. •Types of Marijuana Extracts There are a variety of cannabis concentrates currently available on the market. Here’s a simple guide to help you understand the differences between them: -Kief and Hash Kief is the oldest form of cannabis extract and is the main ingredient used to make hash. Using a dry sifting technique, frozen flower is sifted through fine mesh screens to separate the trichomes from the plant matter. The end product is a fine powder with a high concentration of cannabinoids and terpenes. Regular flower, for example, tends to reach a maximum THC concentration of 25-30%, while good quality kief can reach up to 60%. Kief is often heated and compressed into big blocks, popularly known as hash. The color of the kief or hash will often speak for its purity; a high-quality concentrate is usually golden, while lower quality products will have a greenish tinge, which indicates that it is contaminated with more plant matter. -Ice Water Hash Ice water hash is, you guessed it, a type of hash. The term refers to hash that is made using a ice-water extraction method. Frozen cannabis trimmings are combined with cold water and ice and agitated (either shaken or stirred) in order to separate the brittle trichomes from the plant matter. The mixture is then sifted through various fine sieves and dried to form a granular concentrated that can be pressed or molded by hand. -Rosin Rosin is a cannabis concentrate made using a heat and pressure extraction method which can be easily done at home. Cannabis flower is placed inside parchment paper and pressed between two hot sheets of metal (such as the panels of a hair straightener) to release a sticky, golden oil that’s very similar to shatter. -CO2 Oil CO2 oil is the end product of CO2 extraction, or supercritical fluid extraction. This method, relying on complex and very expensive equipment allows for one of the purest extractions of cannabis compounds currently available on the market. CO2 oil is a beautiful amber/gold color and is jam-packed full of cannabinoids and terpenes. The oil is mixed with food grade propylene glycol or glycerin to keep it liquid at room temperature and is most commonly vaporized in vape pens, although it can also be frozen and dabbed using a regular dab rig. -Hash Oil Hash oil is arguably the most popular marijuana extract currently on the market and is most commonly made using the butane extraction method we described earlier. Hash oil is available in various consistencies which are determined by minute factors in how the cannabinoids and terpenes were extracted from the plant. Here are some of the most common types of hash oil and how they differ from one another: –Shatter Shatter refers to hash oil that has a similar texture to glass and commonly shatters when it is dropped or manipulated. It is clear and usually amber or golden in color and can have a potency of up to 80% THC. Due to its transparency, many mistake shatter as being the purest type of cannabis concentrates. However, shatter simply owes its transparency to the fact that it’s molecules have been left undisturbed and not agitated like the molecules in wax, crumble, or bubble hash. During the manufacturing process, shatter is purged of butane by heating it (often under a vacuum) until the butane evaporates. Because the product isn’t agitated, it’s molecules are undisturbed, making for a transparent concentrate. The consistency of hash oil is governed by factors such as the heat it was exposed to during manufacturing, whether it has been decarboxylated, and it’s terpene contents. Here are some different names applied to concentrates like shatter but with different consistencies: Pull-and-snap: A concentrate similar to shatter but with a more taffy-like consistency which can be pulled, manipulated, and snapped apart, unlike glass-like shatter. Sap: A runnier, sticky concentrate that resembles tree sap or honey. This stuff usually can’t be manipulated by hand and you’ll need some kind of tool to load it into a dab rig without making a mess. –Wax Cannabis wax has a sticky texture which, much like shatter, can differ in consistency. The most obvious difference between shatter and wax is that wax isn’t transparent. Instead, it can have a creamy white color, similar to honey when it solidifies. Wax is opaque because, unlike shatter, its molecules have been agitated. While shatter is just heated during the purging process, waxes are usually whipped. The agitation from the whipping is what creates this non-transparent concentrate. Like shatter, wax is available in a variety of consistencies which are referred to by various names. These include: Crumble: A concentrate with a slightly granular texture that can be pressed or molded by hand. As it’s name suggests, it has a similar texture to the topping on an apple crumble dessert. Honeycomb: Honeycomb waxes are usually hard and very brittle, much like the honeycomb centres in some snack bars. Budder: Budder has a very rich, creamy, and soft texture similar to peanut butter. •Tinctures Tinctures are marijuana extracts made by soaking cannabis trimmings in alcohol. The finished product is a potent extract which is usually applied in drops and administered orally. According to Leafly, tinctures were the most common form of medical cannabis prior to prohibition in 1937. -- source link
