CBD Oil: A How-To Guide for At-Home Extractions

British pharmaceutical company GW Pharmaceuticals recently received FDA approval of their oral solution Epidolex for treating seizures associated with Tuberous Sclerosis, adding another condition to the list of health issues that their CBD oil solution can successfully and safely treat. Individual users, however, claim that cannabis oil helps reduce pain and anxiety, as well as other issues that still await clinical confirmation.

Apart from its medicinal use, CBD oil can also be used to cook various dishes, sauces, dressings, and gummies. The wave of legalization that has swept North America recently also allowed entrepreneurs to start-up businesses and sell oil and other products made via CBD extraction to a wide array of consumers, not only those with medicinal needs.

If you’re looking for a way to make your own oil, however, this article is here to show you how to extract CBD from a cannabis plant at home.

Distinct types of CBD oil

Depending on the strain you use and the preparation method, there are three different types of CBD oil:

  • Full Spectrum
  • Broad Spectrum
  • CBD Isolate

Each of these three types of products provides a separate set of compounds and effects. It’s very important to know what you’re introducing into your system, especially when it comes to potentially psychoactive substances.

Full Spectrum CBD oil contains more than just CBD; there’s a wide array of other cannabinoids, including THC, terpenes, and essential oils. This type of CBD oil allows the use of both leaves and flowers to assure the presence of every compound; however, leaves hold a high concentration of chlorophyll, which gives the oil a dark color and a somewhat bad taste.

Broad Spectrum CBD oil gives you the full set of substances, as well, however, there is no THC, which means you won’t get high or show positive on a drug test if you consume the oil on a regular basis.

CBD Isolate is the purest form of CBD oil extracted from nothing but the plant flower. If you’re opting for this type of oil, you should use hemp flower for this purpose. Hemp has been legal in the U.S. since the passage of the 2018 Farm Bill.

Since the extraction of Full Spectrum CBD oil is the way to obtain the most of the plant’s benefits to our wellbeing, we’ll go through to examine this method, not only because buying complex equipment for marijuana processing might get you in trouble, but also because it’s the simplest process and easy to implement at home. For those of you who would like to know other methods of marijuana oil extraction, we’ll also mention some alternatives at the end.

Extracting CBD oil from a flower

Before you start the process, it’s of paramount importance to know that Ethanol or Ethyl Alcohol is a highly flammable substance so make sure you take every precaution to keep yourself and your environment safe from fire hazard. That being said, let’s get on with the preparation process.

What do you need?

Cannabis flowers – make sure you trim down every leaf and leave nothing but the flower for the extraction process. Break larger buds into smaller pieces to make it easier for processing or even better, grind the flower so that the herb could absorb the alcohol better.

Ethanol – Best use 95% Food-Grade Ethyl alcohol.
Filtering equipment – Best use paper filters or fold gauze into several layers.
Fireproof bowl – the size of the bowl depends on how much material you have prepared.
Large glass jar – This is where you’ll mix alcohol and weed.

Decarboxylation process

To activate cannabinoids, we must place the ground herb into an oven for about 45 minutes. Spread marijuana over a casserole dish or something similar and keep the oven heated at around 110 degrees Celsius. Depending on the granulation, it could take less than 45 minutes for the decarboxylation process, so pay attention not to burn your weed in the oven.

Mixing and filtering

Place your weed into the jar and pour alcohol over it until it covers the weed completely. Stir the mixture every 5 minutes several times and let the mix sit for an hour or two. You can’t let it sit for too long, so don’t worry if you leave it sitting longer than this.

Place the layered gauze or paper filter over the fireproof bowl and start pouring the solution. It’s not a bad idea to repeat the filtering process several times until you’re satisfied with the achieved purity of the filtered solution.

Removing the alcohol

Ethyl alcohol boils at 78 degrees Celsius which is the temperature you should set on your heating surface and slowly mix the solution within the fireproof bowl. Keep the bowl over the heat source until no alcohol vapor or bubbles is appearing on the surface of the heated liquid.

More oil extraction methods

There are numerous ways to extract oil, some even answer the question of how to extract THC from your product. As these require a bit more experience, we’ll only go through some of the most popular methods.

CO2 Extraction

This is one of the newest ways to produce CBD oil and it offers the purest oil extract, called CBD Isolate, free of any additional compounds. It requires a CO2 machine because it relies on carbon dioxide as a solvent. The herb is being placed into a Co2 machine and kept under pressure. This process also includes the Winterization and Decarboxylation process. The first is used to separate CBD from wax and lipids that might be left, while Decarboxylation activates the CBD.

Oil method

Similar to Ethanol extraction, the oil method requires the use of olive or coconut oil as a solvent. One major difference is that the herb is being mixed with water and dehydrated before it’s mixed with the oil and heated. This method is most commonly used by people who need to create CBD tinctures or topicals that can be applied directly to the affected area and deal with muscle pain.

We hope this article has helped you capture the basics of CBD oil extraction. We tried to cover the extraction process as comprehensively as possible so you wouldn’t have any setbacks while trying to make your extract at home. Also, we avoided the use of specialized chemistry equipment because, let’s face it, not too many people have a lab set up in the house. Enjoy your new knowledge and have fun making your CBD oil.

How to Make Cannabis Oil at Home

Making your own cannabis oil at home is easy if you know a few tricks. Learn how to make canna oil in your kitchen with our complete recipe and step-by-step guide.

DIY Cannabis Oil: The Basics

Homemade cannabis oil offers a variety of health and wellness benefits. You may choose to mix the canna oil into another edible or beverage recipe, apply the canna oil topically, or place a few drops under your tongue like a cannabis tincture .

Canna oil has recreational uses as well as medicinal purposes. Here are a few therapeutic uses for cannabis oil:

These possible health benefits also depend on whether you use hemp or marijuana in your oil.

Hemp vs. Marijuana: Which Should You Use?

Hemp or CBD oil is a good choice if you live in a state where cannabis is illegal. CBD hemp oil may also be the right option if you want to avoid “getting high” from tetrahydrocannabinol (THC). Using marijuana with a full spectrum of cannabinoids may offer more potent therapeutic benefits through the entourage effect .

Dosing

Dosing is one of the most challenging issues with cannabis edibles , including canna oil. Too much THC can give you an unpleasant and lingering high. For this reason, it’s a good idea to consult with a physician who can provide you with proper dosing instructions for your body chemistry and level of cannabis experience.

Best Carrier Oil for Cannabis Oil

Many cannabis users report that coconut oil makes the best carrier oil for cannabis oil. Coconut oil contains beneficial fatty acids that go well in both edibles and topicals. However, alternatives to coconut oil also work well, such as vegetable oil or lecithin.

Using Lecithin

Lecithin is a type of fat that allows for ingredients to stick and bind together. Adding lecithin to your recipes and/or into your oil can help the canna oil bind together with other ingredients more readily and improve shelf life. Lecithin has the added benefit of increasing the bioavailability of cannabinoids. Sunflower lecithin is best for a range of diets. Eggs are also a source of lecithin and act as a binding ingredient in baking.

Why It’s Important to Decarboxylate Cannabis

Decarboxylating or “decarbing” cannabis refers to a chemical reaction where a carbon atom is removed from a carbon chain, resulting in the release of carbon dioxide (CO2). Key cannabinoids, like THC and CBD, convert from different original forms during the decarbing process.

For example, THCA (tetrahydrocannabinolic acid) is non-psychoactive in its raw form but becomes psychoactive as THC after decarboxylation. Likewise, CBDA (cannabidiolic acid) is the acid precursor to CBD and may provide its own health benefits .

To change THCA to THC and CBDA to CBD, the raw cannabis flower must be decarboxylated first. Decarboxylating also makes certain cannabinoids, such as CBD, more bioavailable (i.e., your body can process them more easily).

Cannabis Oil Recipe

The following recipe includes everything you need to make cannabis oil at home.

What You’ll Need

  • Rimmed baking tray
  • Baking paper
  • Crockpot, double boiler, or saucepan
  • Cheesecloth or strainer
  • Cooking twine to tie the cheesecloth

Ingredients

  • 3.5 grams of flower
  • 1/2 cup of cooking oil (coconut oil or olive oil)

Steps

Step 1

Break up any cannabis flower or “buds” you have into smaller pieces.

Step 2

Layer the pieces onto a rimmed baking tray lined with baking paper/parchment. Place the baking tray into the center of a preheated oven set to 240°F-248°F (115°C-120°C) for 30-40 minutes. Stir every 10 minutes.

Step 3

Allow the cannabis to cool to room temperature. It should appear darker in color – usually, light brown or yellow, and not as green as fresh cannabis.

Step 4

Once cooled, coarsely grind the cannabis and store it in an airtight container.

Step 5

Combine the cannabis and coconut oil using one of the following methods:

  • In a slow cooker or crockpot on low for about 4-6 hours, stirring occasionally.
  • In a double boiler on low for 6-8 hours, stirring occasionally – a simple heat-proof bowl over a saucepan of boiling water will suffice.
  • On the stove in a saucepan on low heat for 3 hours, stirring regularly. This method is the fastest but most susceptible to scorching. You can add a small amount of water to the oil to prevent scorching.

Note that the temperature of the oil should never exceed 245°F (118°C).

Step 6

Strain your canna-oil through a cheesecloth or strainer to get rid of the plant material.

Alternative Method for Making Canna-Oil

You can also infuse raw cannabis directly in olive or coconut oil by first getting the cannabis-oil mixture to a temperature of between 212°F (100°C) and 230°F (110°C) to decarboxylate it. Then, simmer and double boil it for around 1- 2 hours at a temperature of between 158°F (70°C) and 199°F (93°C).

Double boiling ensures that the oil does not go above 212°F (100°C) after the initial decarboxylation, and means you can decarb the cannabis at a lower temperature over a few hours. However, we recommend decarboxylating the cannabis first rather than decarbing in the oil, which is more efficient.

If you’re double boiling decarbed cannabis, a temperature between 100°F and 120°F (38°C – 49°C) in a double boiler for between 1 and 5 hours is ideal. Use a cheesecloth to hold the raw or decarbed cannabis as you double boil it to avoid straining the oil afterward. Although raw cannabis can be added directly to oil, it is still best to decarb the cannabis first to maximize the shelf life of your oil. You can also use the leftover plant matter to make edibles.

Tips and Tricks for Making Homemade Canna-Oil

Follow these tips and tricks to make the best homemade canna-oil.

Always Cook at Low Temperatures

To retain any acidic cannabinoids, cook at lower temperatures or use the infused oil without cooking it. Once the oil has been infused, you can heat it to a maximum of 350°F (approx 176°C) to keep all the cannabinoids from burning off. We recommend cooking at below 284°F (140°C) or even 248 (120°C).

Extend Shelf-Life with Proper Storage

Cannabinoids do not last forever, and over time and exposure to light, air, and heat, your cannabis-infused oil will decrease potency. Acidic cannabinoids, in particular, are very unstable and do not last very long when exposed to the air.

Any impurities in the cannabis-infused oil will also affect how long a cannabis-infused oil will last. Therefore, properly straining any plant material from the oil is essential to prevent mold and bacteria growth.

Kept in a cool, dark place, cannabis-infused oil should retain its potency for about 1-1.5 years. Room temperature is appropriate if your indoor environment stays below 70 degrees Fahrenheit.

Infuse Oil to Retain Terpenes

Much of the flavor and effect of cannabis come from its terpenes and flavonoids . Infusing decarboxylated cannabis into oil will impart the flavor of the cannabis into the oil. While the terpenes and flavonoids may be pleasant when smelled (and even smoked or vaporized), the taste of cannabis when eaten is not usually as pleasant. Many people try to overcome the taste with sugar, hence the huge variety of medicated sweet treats like pot brownies .

Strain to Help Get Rid of Unpleasant Tastes

Straining away the plant material from the oil will reduce the unpleasant taste but not eliminate it. Matching the flavor profile of the cannabis-infused oil to the dish is possible but not easy considering the number of terpenes and terpenoids at play. Other ingredients can mask the flavor, as can infusing the oil with other herbs and spices.

How Can I Legally Buy Cannabis to Make Canna Oil?

Stay informed about the current cannabis laws in your state to know if you can legally buy cannabis to make canna oil.

Is Canna Oil the Same as CBD Oil?

No. The difference between canna oil and CBD oil comes down to THC. Canna oil contains a significant amount of THC, while CBD oil contains only trace amounts of THC, i.e., not enough to have psychoactive effects.

How Long Does It Take to Make Cannabis Oil?

If using a double-boiler, the infusion process to make canna oil takes approximately 6 to 8 hours until you have a final product.
