If you are on the lookout for a pure cannabis extract, consider multiple options. Each extraction method has its strengths and shortcomings regarding how it is produced and what you can use it for. This article covers the major types of solventless extractions:
CO2 Oil
Many people, see CO2 extraction as a safe alternative to other types of extraction because it does not produce any leftover chemicals or contaminants. The process involves extracting oils from cannabis that utilizes carbon dioxide and another solvent. To extract the oil, you let the plant material soak in water and then mix it with carbon dioxide. Afterward, you put the mixture under pressure in a closed system to extract the cannabinoids and terpenes (the other compounds responsible for the flavor and aroma.) CO2 extraction is the most cost-effective way to make extracts because it does not require expensive equipment or specialized workshops.
Butane Hash Oil (BHO)
This solvent-based extraction uses butane to separate THC from hemp or cannabis flower. The resultant product is a thick liquid that produces strong psychoactive effects when consumed but does not have the same smoothness or flavor profile as other extracts. Some people will refer to butane hash oil (BHO) as BHOG. The best of these extracts are made using a stainless steel container that is heated in conjunction with a vacuum so that the butane can be properly contained until all of the THC is extracted. Since it is made with an organic solvent, people who make this Los Angeles solventless must have permits and operate following proper safety precautions as outlined by law.
Cannabis terpene extraction
Terpenes give cannabis its distinct flavors and aromas. Each strain of cannabis has different terpenes that can be used to increase its therapeutic and performance benefits. There are many ways to extract these oils from the plant, but the most common method is solventless extraction.
The most popular solventless extraction method today is the CO2 oil method, although many others. These methods typically involve using high heat and pressure to preserve the terpene content, which means there is no chemical residue. In addition, all of these methods use less water than other extraction methods, so their production does not result in waste or pollution and can be sustainable. Keep in mind that all of these methods work differently with each cannabis strain/product produced.
