21 Feb CO2 Hash Oil
Carbon Dioxide,CO2, is a gas at standard temperature and pressure, but it becomes a supercritical fluid when pressurized. CO2 is a naturally occurring gas and is even emitted from people when they exhale. CO2 is used in the food, dry cleaning and herbal supplement industries. CO2 is even used in the process to decaffeinate coffee beans. The CO2 extraction process for hash oil is low in toxicity and does not run the risk of leaving heavy metals behind such as in the butane extraction process. Supercritical CO2 is put into a pressurized container filled with marijuana, the CO2 attaches itself to the THC then is filtered out of the plant matter once the container is depressurized. The CO2 evaporates and the hash oil is the remaining product. CO2 oil is great for vaporizing pens and can have THC levels of 70% or higher.
