When liquid or gas CO2 is pressurized to its super critical state and passed through cannabis, this is referred to as CO2extraction. Any pressure over 1078 PSI is sufficient to strip away waxes and cannabinoids to create a more oily less viscous hashoil. The CO2extraction of cannabisoil and concentrates has become very popular in the search of maximum potency, higher terpenes, and superior quality.
CO2extraction is also known as supercritical fluid extraction (SFE) and it utilizes carbon dioxide heat that is compressed to a critical point. Around 90 degrees Fahrenheit is the point at which CO2 can hit its critical point. This temperature is cool enough that the terpenes and cannabinoids of the cannabis plant are not compromised during the extraction.
The CO2 is compressed and converted into a cool liquid state and then is passed through marijuana. This removes the trichome and terpene-rich oils and waxes out of the plant material as the liquefied CO2 flows through the marijuana. This method is quick and easily penetrates the
