how to extract cbd oil

• Working with solvents can cause injury if not used correctly, they are highly flammable
• The oil can remain contaminated with solvent, which is dangerous for the end-user
• Higher temperatures risk destroying some essential terpenes and other smaller compounds

First, to perform olive oil extraction at home, you need to make sure your plant material is decarboxylated. In short, that means it undergoes the process of acidic cannabinoids being activated via heat. That, of course, happens when you smoke or vape it, but it can also happen if you put it in the oven.

• Yields are low and impractical
• No way of controlling purity, with minimal levels of CBD
• CBD extract contains plant material and unwanted cannabinoids

Pros of solvent extraction

• Can be performed easily at home
• Relatively safe, with no previous extraction experience needed
• Greater degree of purity compared to solventless extraction

• Co₂ extraction is an industrial process, making it highly expensive
• Requires expertise to perform correctly

• Allows for the extraction of clean and safe concentrates without the use of additional additives or contaminants.
• Offers highly efficient yields, getting the most out of the hemp plant.
• CO₂ extraction is sustainable and environmentally friendly

Once decarboxylated, mix your plant matter with olive oil and heat it on the stove for several hours. CBD, other cannabinoids and essential terpenes will bind to the fats in the oil, creating an infused product. Finally, the mixture is left to cool before being filtered to remove any leftover plant material.

Many cannabis experts agree that the CO2 method is best for producing premium oil that stays potent longer because the hemp or cannabis compounds remain stable during this type of extraction. Full-spectrum CBD oil, prized for its potency and purity, is made via CO2 extraction. Other methods may destabilize the compounds, potentially creating lower-quality CBD oil with a shorter shelf life.

Solvent extraction method: The solvent extraction process is similar to using CO2, but it’s notably cheaper and faster. Butane has long been used in cannabis extraction but ethanol and propane are also popular. This method also uses a closed-loop system wherein the liquid butane, propane, or ethanol washes over the cannabis, releasing the CBD, other cannabinoids, and terpenes. The solvent then has to be carefully heated or cooled to separate the solvent from the extracted compounds without damaging them. The main drawback of solvent extraction is that some solvents may extract impurities from the cannabis plant material, which could give the end-product an unpleasant taste.

Terpenes are the naturally-occurring compounds that infuse cannabis with its signature aromas and flavors as well as potential therapeutic benefits. Full-spectrum CBD products rely on extraction methods that can keep these compounds intact.

Which CBD extraction method is best?

The process of CBD extraction is fairly expedient and can take place in a single afternoon. According to Leising, it takes about three to four hours to process up to 1,200 pounds of cannabis.

It depends on what extraction method you’re considering. Let’s say you have a thriving indoor cannabis garden and want to consume the cannabis you’ve harvested without having to smoke it all. You can safely make CBD oil at home via a simple infusion and consume a high concentration of cannabinoids without risking life or limb.

The same is not true for the solvent method, which often fails to eliminate such impurities.

Andrew Leising, VP of Strategic Sourcing for Balanced Health Botanicals, elaborated on the process: “CO2 is a scalable and highly versatile form of extraction. There are CO2 extraction units built to process anywhere from 1 to 1,200 pounds of biomass in a single run. With CO2 extraction, you can not only extract cannabinoids on a large scale efficiently, you can extract specific compounds like terpenes.”
