Cannabis oil extraction is becoming a lucrative business option. Some of the most effective methods of oil extraction include solvent-free extraction, alcohol extraction, butane extraction and CO2 extraction. Each produces a slightly different chemical composition in the resulting oil and has varying cost and time constraints.
Cannabis oil extraction need not involve highly technical equipment. Lower grade oils can be produced by methods as simple as grating, straining, or grinding. The scraped cannabis segments are then heated under pressure to purify the oil. This simple method can easily be done with items most people have in their homes, but the manual labor and decreased quality in the results can be discouraging.
This fairly simple form of extraction involves a solvent, such as alcohol. The solvent breaks down compounds within the plant, allowing for easy extraction. Subsequently, the mixture is warmed to allow the alcohol to evaporate. When done correctly, this method produces a pure, pleasant-tasting cannabis oil. However, there is a high risk of combustion during the evaporation process.
With this method, cannabis hash is combined with CO2 and then compressed in order to change the chemical composition. As this process is repeated, the cannabis is broken down into its various useful and less useful components. The advantages of this process include less waste and high production, although the compressors can be more of an investment than in many other extraction methods.
This method uses Butane or sometimes propane as a solvent. When the cannabis hash is combined with butane and pressurized and heated, the harsher components break down, allowing the oils to separate. Although this method is somewhat dangerous due to the combustible nature of butane, this method has remained popular due to the low start-up cost and high yield.
There are many methods of extracting cannabis oil, which are more or less effective. In any method, there are risks and time constraints, yet all are exact sciences that are able to produce refined cannabis oils.
