This liquid is passed through the best pot you can find, stripping the resin and the chemicals it contains, including THC, CBD, and terpenes. The process is technically known as “supercritical fluid extraction,” and it uses the CO 2 extraction equipment to freeze and compress CO 2 gas into a cold, “supercritical” liquid state. The process is rather complicated and requires good weed, a CO 2 extractor, and a CO 2 extraction machine. The CO 2 in turn keeps plants alive, and they re-convert it into the oxygen that we breathe.ĬO2 extraction produces cleaner, tastier and healthier cannabis oil. When you inhale, your body converts oxygen to CO 2, which you then exhale. The end result is safer, healthier, and tastier, even if CO 2 hash oil is harder to make.ĬO 2 extraction is an ideal manufacturing method because carbon dioxide is present everywhere in the Earth’s atmosphere. The resulting liquid is then boiled to evaporate what remains of the solvent.ĬO 2 oil is made using carbon dioxide (CO 2) instead of butane, alcohol, or other solvents. The solvents – sometimes butane, sometimes alcohol, sometimes other chemicals – are used to strip potent cannabis resin off the plant. Unlike butane oil (bho) and oil made with rubbing alcohol (isopropyl), CO 2 oil is safe to extract and use.Ĭhemical extraction methods, including CO 2 wax extraction, require liquid solvents. This article will explain the basics of CO 2 extraction, a method of making hash oil using carbon dioxide (CO 2). If you’re going to make hash oil at home, it’s important that you research whatever method you choose, lest you make terrible oil – or explode your house. Some methods are more common than others, and some are safer. Sometimes these marijuana concentrates are high in THC, sometimes low sometimes high in CBD, sometimes less so.īut the biggest difference between one batch of oil (aka wax, shatter, honey oil) and another is how they’re made.


Hash oil comes in many forms, all of them popular.
