How To Make The Best Medical Cannabis Oil

Cannabis oil is used to treat some diseases, like cancer, epilepsy, and multiple sclerosis. It can be found under various names, such as black oil, Rick Simpson oil (RSO), and Phoenix tears. It is usually taken in capsules or via syringe. When it comes to strain, your choice should depend on what you need to treat. For example, cancer treatment requires strains high in CBD and THC, but other diseases, like epilepsy, respond much better to lower strains. However, cannabis oil is rather expensive, so, in this article, we will show you how to make some yourself.


One ounce of high-quality medical cannabis or 2 to 3 ounces of trim. Everclear alcohol

Double boiler or rice cooker

1 medium glass mixing bowl

Cheesecloth or clean nylon stocking

Large wooden spoon

Silicone spatula

2-quart mixing cup or container

Sterile oral syringes

Cooking thermometer

Fans or ventilation (if indoors)

Parchment of paper


Step 1

Make sure your working space is clear and clean. Keep a fire extinguisher nearby, since you are dealing with flammable items. The space should be well ventilated, so we recommend you do it outdoors if you can. Use some burn protection, like respiratory mask and goggles.

Step 2

(Use a solvent such as high-proof alcohol as it helps burn off any potential carcinogens.)

Put the cannabis to the glass bowl. Cover it with alcohol then stir with a wooden spoon for couple of munutes.

Step 3:

Cover your 2-quart measuring cup or extra container with cheesecloth or a clean nylon stocking. Strain the cannabis by pouring it over.  Pour your cannabis mixture over your cheesecloth into the second container. Squeeze out the remaining liquid from the nylon or the cheesecloth.The first straining should result in a dark green liquid; a mix of alcohol and cannabis resin.

Take the strained plant material and put it back into the glass mixing bowl. Pour more Everclear over the top until it is fully submerged. Stir continuously with the wooden spoon for a couple of minutes. Repeat the straining process and empty your second batch of alcohol into the runoff container.

Step 4:

If you’re indoors, keep your fan on your cooking medium and direct off gasses toward an open window or door.

Option A: Rice cooker

Before you make oil with a rice cooker, you may want to test to see how hot your cooker gets beforehand. You can do this by adding in some water prior to cooking your oil and bringing it to a boil in the cooker.

Use your thermometer to test the temperature of the water. Touch the thermometer to the bottom surface, so you know exactly how hot it will get.

Fill the rice cooker 3/4ths full with the canna-alcohol (you can add in more liquid later as the levels drop with cooking.)

Turn your rice cooker on, and LEAVE THE LID OPEN.  You can gently drape some cheesecloth over the rice cooker to keep any dust out of the oil. Make sure the cloth is not touching the oil (see video below)

Use the White Rice setting and heat your liquid on high and allow the solvent to boil down.

Remove the rice cooker pot from the machine when the oil becomes thick and dark green. Remember to use your oven mitts

Stir the liquid and watch the bubbles. When the amount of bubbles rising to the top decreases substantially, you’re ready to remove the oil

Use your silicone spatula to remove the cannabis oil from the pot.

Using a toothpick, gently scrape off the cannabis oil onto some parchment paper

Option B: Double boiler

Follow the same safety tips as above before beginning to heat your extraction with a double boiler.

Fill the bottom of your double boiler with water

Pour canna-alcohol into the top pan

Turn your burner on high and wait for your top pot to boil

Once the liquid bubbles, immediately turn off your burner. The boiling water will do the rest

Let the mixture in the top pan bubble for 15 to 20 minutes. You can turn the burner back on if you stop getting bubbles

Once the oil is nice and thick, it is complete. You can remove it from the pan and scrape it out onto parchment paper when it cools

Step 5: Fill your syringes

Once the oil has cooled, use the syringe for dosing, or to fill capsules to make cannabis pills.
