CO₂ Extraction

CO₂ extraction is a technique that forces supercritical carbon dioxide through the cannabis plant to draw out their chemical contents. This method of extraction results in cannabis concentrations that can contain a range of flavonoids, cannabinoids, and terpenes, and are commonly referred to as CO₂ oils.

  

Is CO₂ extraction commonly used for medical cannabis oils?

 

Yes, in the UK, CO₂ supercritical extraction is the most often used method for producing medical cannabis oils. This is because it results in a cleaner and more precise extraction compared to other methods such as butane or ethanol extraction.

  

Why is CO₂ extraction cleaner than other extraction methods?

  

CO₂ extraction is considered cleaner because it does not require any harmful solvents. Butane and ethanol extractions, for example, can leave behind residual chemicals that may harm a patient's health when administered. CO₂ extraction also allows for precise control over temperature and pressure, leading to a more effective and focused extraction process. 

  

What are the benefits of CO₂ extraction for medical cannabis oils?

 

One of the greatest benefits of CO₂ extraction is its ability to produce high-quality, concentrated extracts. This is important for medical cannabis oil production, as it allows for a more potent and consistent product. CO₂ extraction is also considered very environmentally friendly, as it does not produce any toxic by-products or waste.

  

Are there any downsides to using CO₂ extraction?

  

While CO₂ extraction comes with a range of advantages, it can also be expensive, requiring specialised equipment and trained professionals. This is one of the reasons why CO₂ extracted medical cannabis oils may be more costly than other types of extracts on the market.
