Recipe: Making Cannabis Infused Oils with Your Slow Cooker

This straightforward recipe for making cannabis infused oils in your slow cooker is so simple you’ll wish you tried ages ago.


The Benefits of Using a Slow Cooker

Easy-peasy – You no longer have to spend the whole day stuck in the kitchen keeping an eye on the stove to make sure the oil doesn’t boil – with the slow cooker method you simply set it up, switch it on and go to bed and in the morning, your oil is ready- what a pleasure!

No Smell – The second big benefit is that the smell is almost non-existent. The slow cooker method  contains the odors so you don’t have to suffocate in clouds of incense for fear of the neighbours smelling your herb.


infused cannabis oil 50 grams cannabis

500 ml oil (coconut/olive/almond/etc)


You can use as much or as little as you like. The basic math is a 1:10 ratio of cannabis to oil. IE: 10 grams of cannabis to 100 ml coconut oil.



2 x Container with lid (preferably glass not plastic) or bowl, string and wax wrap


Bottle (for storage)


  1. Put the slow cooker on to the ‘low’ setting and fill 2/3 with marijuana leaves

  2. Put the cannabis in the container with the oil and pour the oil over the cannabis.

  3. Using the blender or scissors, chop the cannabis up into small pieces – not too fine but ensure there’s not large stalks that might rip the pantyhose later.

  4. Seal the container tightly or cover it in wax wrap and use the string to keep it secure.

  5. Place the sealed container in the slow cooker.

  6. Put the lid on the slow cooker and leave it to cook for 4-8 hours

  7. Once it’s finished cooking, switch off the slow cooker and remove the container from the water.

  8. Ensure the container is wiped dry of moisture on the outside before opening.

  9. Cover the opening with pantyhose and make a sieve over the top – ensure it is well secured.

  10. Pour the oil out through the pantyhose into another container.

  11. Once all the oil has been drained into the new container, seal this container and store it in a cool dark place.

Why Coconut Oil?

Coconut oil is great for you for a multitude of reasons – great at reducing bad cholesterol and high in saturated fats – which makes it excellent for extracting both THC and CBD’s. And when you combine cannabinoids with fat, the fat actually helps the cannabinoids travel through your digestive and assist with better absorption of the different properties.

500 ml Pure Virgin Organic Coconut oil

50 g Dry Cannabis

(Roughly 100 ml of coconut oil to 10 grams of powdered cannabis)

NOTE: I do not recommend decarboxylating the plant material unless you are specifically making oil to treat cancer where a highr THC ratio is required. For all other conditions no decarboxylating is required as you want to maximize your CBD’s and the heat from decarboxylating can destroy CBD’s. You will still convert THC-A into THC through the extraction process.


  1. Separate the flowers from seeds and stalks. You can use a sieve to help with this process. Pull out any larger stalks and put the dried flower into a sieve and rub it through – the seeds and smaller stalks will be held back and the plant matter will fall through. 

  2. Break your cannabis up or use scissors to chop it finely.

  3. Gently melt the coconut oil – do not let it come to the boil.

  4. Double boil: Use a large pot with water in it as the base. Put the smaller pot with the coconut oil into this pot. The water in the bottom pot will help keep the coconut oil from getting overheated.Water has a boiling point of 100C which helps to keep the coconut oil at this temperature too.

  5. Use only enough oil to cover the cannabis amount used, work on 100 ml of oil to 10 grams of powdered cannabis for a good quality.

  6. Once the oil is melted, add the chopped cannabis. The oil must never bubble or boil therefore you have to keep a constant eye on the pot, stirring at regular intervals.

  7. If the oil starts to bubble reduce the heat immediately even if this means switching off for a while this is no problem – the oil must never boil or bubble.

  8. Continue with this process for six hours always checking the heat and keeping it on constant low heat, using a wooden spoon to stir at frequent intervals.

  9. Six hours may feel long but it produces the best possible oil.

  10. After six hours turn the heat off and let the oil cool. There is no harm in switching off and continuing after a few hours if time or circumstances do not permit, even if you are cooking on a fire.

  11. Once the oil has cooled but is still fluid strain it through a muslin cloth, stocking or a fine mesh sieve using the back of a teaspoon to press the oil through. It is much easier to use the cloth or stocking which you can secure over a bowl with an elastic band.

  12. Store the oil in glass jar and keep it in a cool dry place.

    Coconut oil naturally solidifies in cooler temperatures and all you have to do is place the glass jar in some boiling warm water and let it melt. Always remember to open the glass jar before you put it in boiling water as it will crack and many patients have lost their valuable medicine in this way. You can also use your Cannabis Coconut oil in the solid form as butter or swallow it solid with water, like a pill.

  14. Do not leave the oil on the heat unattended – you will damage the cannabinoids and lose potency. Even street marijuana is expensive and this is a valuable lesson learned.

Coconut oil has a smoke point of 171 degrees Celsius. At 100 degrees and less it cannot produce any dangerous fumes because it will not create smoke at this temperature. So this recipe can be followed while cooking on gas, electricity, even fire, and anyone can make their own medicine with this recipe.
