What is a common method of cannabis extraction known for its purity?

CO2 extraction is recognized as a common method for extracting cannabis due to its high levels of purity and efficiency. This method utilizes carbon dioxide under high pressure and low temperature. In its supercritical state, CO2 acts as a solvent, allowing it to efficiently extract cannabinoids and terpenes from the cannabis plant while preserving their integrity and quality.

The purity achieved through CO2 extraction is attributed to its ability to selectively extract desired compounds without pulling in unwanted materials, such as waxes or chlorophyll. Additionally, CO2 extraction leaves no residual solvents, making it a preferred method for those seeking clean and safe products.

In comparison, other extraction methods may not achieve the same level of purity. For instance, alcohol extraction can leave behind residual solvents if not processed correctly, which may affect the final product’s quality. Butane extraction, while effective in producing concentrated products, can also pose safety risks due to the flammability of butane and the potential for residual solvents. Water extraction, though a more natural approach, may not yield as potent results or preserve the full spectrum of cannabinoids and terpenes as effectively. Thus, CO2 extraction stands out in the cannabis industry for its purity and efficacy.
