There are many different types of cannabis concentrates, but one thing that they have in common is that they all come from a cannabis extraction process that creates a more potent form of the original marijuana that they come from.
Rosin. This kind of marijuana concentrate is actually a solid substance as opposed to an oil as the final product. The kind of cannabis extraction method that is used to obtain rosin is one of the most simple methods to do, which also means that it is more affordable. Rosin is made by applying heat and pressure to separate the rosin from the original plant. You do not need a lot of fancy extraction equipment to do this method unlike some other types of extraction, but you also do not get as potent of a final product. Rosin extraction is considered a solventless hash, so it can also be safer to try to make on your own when compared to other types of concentrates.
Butane Hash Oil. This type of concentrate is more difficult to make and should only be done by an experienced professional. The marijuana extraction method used to create the products will often result in a form of concentrate that is very high in THC. This makes it an effective treatment for people that are looking for natural pain management, and is very popular among people with cancer, arthritis, chronic pain conditions and even sleeping disorders. The reason why it is so important to get this product from a professional extractor is that if the extraction is not done correctly, then there could possibly be residual products left behind in the oil. Things like pesticides or leftover butane could be present which are very bad for the body. Butane is also very flammable, which is another reason why you should leave this extraction method to the professionals. Butane hash oil can create several different final products depending on the temperature that the butane is kept at. Some of the final products of this type of extraction method are shatter, sap, budder, crumble and honeycomb. Many people have attempted this type of extraction at home, but they skip the vital end step, which is to test the final product for any kind of contaminants or impurities. You should only consider purchasing products that have been tested and deemed safe.
Supercritical CO2 Oil. Supercritical CO2 extraction has been around for a long time, and has been used in many other markets besides medical marijuana. In fact, supercritical CO2 is the method that is used to make carbonated sodas. It is also used to remove the caffeine from coffee beans (decafe, any one?) and most recently it has started to become a method of cleaning clothes at environmentally friendly dry cleaners. This kind of marijuana extraction is popular because it is safe and does not involve any harmful chemicals. Supercritical CO2 is put into a closed system with the marijuana plant where it filters away the chemicals from the physical plant. The chemicals are saved and the plant matter is discarded.
