How to Make CBD Oil [Explained for Dummies]

With CBD being the hot topic of the moment, many members of the British public are itching to try it for themselves. Those who use CBD oil say that it helps them to generally feel “better,” perhaps sleeping a little deeper and feeling a little calmer. CBD certainly has a lot of people backing it now.

But cannabidiol products tend to be rather expensive. You can end up paying quite a fee for a comparatively small bottle, using it up all too quickly. If CBD has been working for you and you want to consume it regularly, you might be wondering if there is a cheaper way to go about it.

Well, actually, you can try making your own CBD oil at home. It will be nowhere near as potent as the stuff you can buy in shops or online, but it might just do the trick if you only need a low dose.

So, how is CBD oil created?

How is CBD Oil Usually Made?

Manufacturers most often make CBD oil using either solvents like butane or using CO2. By far the most method is to use supercritical CO2, since the safety of other solvents is sometimes called into question.

In the solvent method, plant matter is placed within a solvent which extracts compounds such as CBD, CBG, and terpenes. The plant matter is removed and the mixture is then heated to evaporate the solvent, leaving behind only the isolated plant compounds. Theoretically, this leaves the compounds safe for consumption, but it is not the ideal extraction method to use at home. If the butane is incorrectly evaporated and solvent remains within the extract, it could be harmful to consume. Furthermore, the entire process is dangerous because solvents are highly flammable.

As a result, most companies elect to use CO2 extraction. CO2 extraction involves freezing and compressing carbon dioxide until it becomes a “supercritical” cold liquid. In this state, CO2 behaves as both a liquid and a gas, acting as a sort of solvent.

This extraction method requires some incredibly high tech, expensive equipment. For this reason, you’re not going to be performing it at home! First off, you need tech that can lower the temperature of your CO2 to -69˚F and increase the pressure to 75 pounds per square inch (psi).

Then, you need to pass this supercritical CO2 through an extraction chamber containing the plant matter. Since it acts as a solvent, the cannabinoids, terpenes and flavonoids are all extracted from the plant matter. These are all filtered into a collection chamber. The CO2 is looped back around, recycled, and can be used again and again in the process.

CO2 extraction is favoured because it is extremely safe, environmentally friendly, and creates products that are not harmful when consumed. As such, it is ideal for mass producers. But it is not great for people who want to try their hand at making CBD oil at home.

Can I Make My Own CBD Oil at Home?

It is actually possible to create your own CBD oil, albeit rather difficult. First off, you will need to get your hands on some CBD-rich hemp flower. Since hemp can only be grown in the UK if you have a license from the Home Office, this could prove to be a challenge. But if you do have access to hemp flower, then making CBD oil is actually quite simple.

You can make CBD oil quite safely using ingredients and equipment you probably already have at home. Bear in mind, however, that the quality of the oil will be very different to what you buy in shops. There will probably be less usable CBD, for a start.

Nevertheless, the price difference can be pretty significant. If you don’t mind low-quality CBD oil, want to save some cash, and can get your hands on some hemp, then there are a few ways to make CBD oil…

How to Make: CBD Olive Oil

Olive oil can be a decent carrier oil for CBD. It is not the favourite, but it still does the job.

You will need:

  • CBD-rich hemp flower
  • Oven-proof dish
  • Mason jar
  • Olive oil
  • Saucepan
  • Cheesecloth


  1. First, you need to decarboxylate the hemp to activate the cannabinoids and convert acidic compounds like CBDa into CBD. To do this, place the hemp flowers in an oven-proof dish and bake it in the oven at 230˚F for 40 minutes.
  2. Add the decarboxylated hemp to a mason jar, and fill it up with olive oil.
  3. Place the mason jar into a saucepan and fill it with water. Bring it to the boil, and leave it for three hours. Check occasionally to ensure the water has not evaporated.
  4. Turn the stove off and allow the mixture to sit for another three hours. Then heat it again for three hours, and finally leave it to sit all night.
  5. Your CBD oil will be ready in the morning. Strain out the plant matter using a cheesecloth, squeeze, and the oil will be ready.

How to Make: CBD Coconut Oil

Coconut oil is used in a number of health products, and may add a little something extra to your CBD supplement. Here’s how to make it:

You will need:

  • Decarboxylated hemp flower (see above)
  • Coconut oil
  • Cheesecloth
  • Hand grinder
  • Slow cooker or saucepan


  1. As seen in the steps above, be sure to decarboxylate your hemp flower to ensure that the CBD and other cannabinoids are active. You can grind up the flower before for better results, but do not grind it into a fine powder – just break it down a little.
  2. Add the flower to the slow cooker or saucepan with the coconut oil. In a slow cooker, put the heat on slow and cook for 4-6 hours. You can add a bit of water to avoid burning.
  3. Allow the mixture to cool fully, then strain it through a cheesecloth. Congratulations! Your oil is ready.

Final Thoughts on Homemade CBD Oil

As you can see, making CBD oil is very easy – providing that you can easily get your hands on hemp. Once you have made CBD oil, you can also go on to making edibles, skin care products, and even bath bombs. The world is your oyster!

Do remember that your CBD oil will not really be of the highest quality. You might be better off buying from a reputable seller if you really need the CBD. But if money is tight, making your own could be an option.

Always be careful when heating oil to high temperatures; exercise caution throughout the entire process. Ensure that you keep an eye on the pot to make sure your environment is safe.
