What are CO2 Extracts?
CO2 extracts are cannabis extracts made using CO2, as opposed to other extraction methods like butane. Many argue that the future of weed extracts is CO2, as it allows extraction without any potentially harmful chemicals and retains the terpenes and other desirable qualities of the weed in the extract.
CO2 oil was the most common form of CO2 extract for many years, but newer extraction machines allow manufacturers to produce the full spectrum of concentrates – budder, oil, shatter, wax – by making some simple adjustments to the way they process the plant.
With butane extracts, the manufacturer must be careful to purge the butane residue to avoid leaving any behind that would be consumed by the user. But with CO2, there is no need to purge. Much like a soda will go flat when left in the open air, the last stage of making a CO2 extract simply involves leaving the concentrate to let the CO2 evaporate.
How to Smoke CO2 Extracts
CO2 extracts are used exactly the same way that other concentrates are used. Whether extracted with butane or CO2, the final material must be vaporized and then inhaled. The most popular ways to smoke CO2 extracts include:
Combined with Flower
The most basic way to smoke extracts that are more solid in consistency, like wax, is to crumble them up over a bowl or joint. Now, this is not the best way to smoke CO2 extracts, but it is the most accessible for those without a vape or a dab rig.
Most vaporizers will vaporize CO2 extracts, including shatter, resin and oil.
Many CO2 extract users prefer to dab. Dabbing involves heating up a surface to the point where it will vaporize the extract – like the hot knife method, or a nail on an oil rig.
Characteristics and Benefits of Smoking CO2 Extracts
CO2 extracts are concentrates, which means they tend to contain high levels of cannabinoids like THC. Those new to extracts are encouraged to take it slow at first.
CO2 extracts offer considerable benefits to the discerning smoker, as they are guaranteed to be free of any solvents or other undesirable materials.
