The Step-by-Step Process
- Step 1 - Create a water bath that stays at approximately 180-190° F. The printable instructions below are for using a crockpot.
- Step 2 - While the water bath is heating, measure and decarb your cannabis flower. Use my traditional oven or Instant pot decarboxylation tutorials, if needed.
- Step 3 - Evenly add the decarbed flower and olive oil to the mason jars you plan on using. If you plan on using lecithin, add it now.
- Step 4 - Place the jars into the water bath. Place the lid on the crockpot and leave it alone to infuse for 4 hours. After 4 hours, remove the jars from the water and allow them to cool.
The Step-By-Step Process
- Step 5 - Set up a straining station to separate the plant matter from the oil. Options include a paper filter and funnel, cheesecloth, French press, or a simple coffee filter.
- Step 6 - Strain the oil . You can save the leftover cannabis pulp for use in future recipes.
- Step 7 - Return the prepared oil to whatever jar you would like to store it in; a mason jar works well.
- Step 8 - Store the oil in a cool, dry place. It will last longer if stored in the refrigerator and even longer if stored in the freezer.

Olive Oil For Good Health
Extra-virgin olive oil (EVOO) is widely known as one of the world’s healthiest oils (1).
So much so that people tend to live longer and healthier lives in areas where olive oil is a staple part of the diet.
EVOO is also extremely rich in antioxidants. It contains polyphenols which act as antioxidants by reducing oxidative stress throughout your body.
Antioxidants also aid in strengthening your immune system, making your body more resistant to infections and inflammation (3).
Notes & Expert Tips
Below is a general guideline explaining the most important steps you need to take to make cannabis olive oil at home.
To reap the benefits of CBD or THC, you must decarboxylate the cannabis before combining it with the oil. This process is as simple as heating it in the oven.
For this recipe, we decarb our cannabis flower in the oven before combining it with the olive oil and placing it into the crockpot. Therefore, we can have a shorter infusion time, a total of four hours.
Consider the Strain You're Using
Each cannabis strain contains varying amounts and ratios of different cannabinoids and terpenes.
Because each cannabinoid and terpene decarboxylates at a different temperature, you will want to consider the best temperature and cooking time for your particular strain.
Additionally, the final potency and intoxicating effects will vary depending on THC or CBD dominant strain.
The Freshness of Product
You notice differences in your final product depending on the freshness of the material you start with.
The potency will vary with the freshness of the material, the cannabinoid concentration, and how much you ultimately use.
Save The Leftover Pulp
After the straining process, you will be leftover with a ball of spent cannabis flower, also called leftover pulp or sludge.
While some folks say it is garbage and throw it away, I've heard too many success stories of people using the pulp with great results.
Anecdotally, many members of my Well With Cannabis Community have reported still receiving pleasant, intoxicating high effects when consuming the pulp.
This supports the theory that at least some percentage of cannabinoids are left behind in the plant matter.
I believe in both nutrition and sustainability, so I recommend keeping your leftover pulp to use in any one of these 15 ways to use leftover cannabis pulp.

Easy Crockpot Cannabis Olive Oil Recipe
- 16 ounces extra-virgin olive oil
- 1 ounce decarbed cannabis flower
- Lay a clean tea towel down on the bottom of the crockpot. This will create a buffer between your mason jars and the crockpot, potentially preventing any jar from moving or cracking during cooking. Fill your crockpot with enough warm to hot water to cover the top of the mason jars you plan on using by an inch to create a water bath.
- Place the digital instant-read thermometer into the water. Start the crockpot heat on high. When a temperature of 185° F is reached, turn the crockpot to low.
- While the water bath is heating in the crockpot, measure and decarb the cannabis flower according to the appropriate decarb time and temperature.
- Evenly divide the olive oil between the mason jars you plan on using. You can either use pint-sized or half-pint-sized jars, it's you're preference, just be sure they fit in your crockpot. No matter the size, be sure to leave a ½ inch headspace from the top.
- Evenly divide the decarbed flower between the olive oil-filled jars. Wipe the rim of the jars with a clean towel and place the lid on. Tighten the metal ring to finger-tip tightness; it does not have to be tightened all the way. Do not tighten too tightly.
- Once the water bath reaches a temperature of 185° F, carefully place the jars into the water bath. Place the lid on the crockpot and leave it alone to infuse for 4 hours.
- After 4 hours, carefully remove the lid, followed by the jars from the hot water. Set them aside to cool.
- Once cool enough to handle, you will want to strain the oil through a paper filter and funnel, cheesecloth, or French press to separate the plant-matter from the olive oil.
- Save the leftover cannabis pulp for use in future recipes. Then return the prepared cannabis olive oil to whatever jar you would like to store it in.
- Store the prepared cannabis olive oil in a cool, dry place. It will last longer if stored in the refrigerator and even longer if stored in the freezer.
- Yield: ~16 ounces / ~2 cups. You can make a smaller batch by following this ratio guide.
- Temperature control: The water bath does not need to stay perfectly at 185° F the whole time. Any temperature between 170°-190°F is OK.
- Safety: Sanitize your jars by keeping them submerged in the 185° F crockpot for 10 at least minutes. This step is not necessary, but good practice.
- Floating jars: The mason jar may float when placed in the water bath. Simply put something heat and water safe over the top of the jar to weigh it down, a clean rock works well.
- Alternative carrier oil options include: avocado oil, hemp seed oil, grape seed oil, coconut oil
