This is the most common method used for industrial and high yield production and extraction of CBD oils. It is very safe, effective and incorporates high end technology to achieve ultimate success. This extraction method basically involves using pressurized carbon dioxide to extract the CBD compound from the cannabis plant. At certain temperatures and pressures, CO2 acts like a solvent that enables extraction of CBD. It is a lot safer than using ethanol or butane. Specialized equipment is required to successfully perform this procedure.
CO2 does not contaminate the oil, therefore is safe for human use and does not pose a health risk. The method is effective and produces a high yield.
The use of specialized equipment makes the process costly to perform. It requires some level of expertise and cannot be carried out by amateurs.
