- Cannabis oil can be made at home with oil, cannabis, a pot, and a strainer.
- The process isn't that different than infusing any herb oil for cooking.
- You can use your finished weed oil in baking, stir fries, salad dressings, and more.
Weed oil is one of the most versatile substances to have in the home. It can be used for any cannabis edibles, from pot brownies to weed stir fries. A well-dosed cannabis oil will give you a great high, and may also help with sleep, pain relief, and relaxation.
Homemade cannabis-infused oil like the one we outline here is much more potent than hemp oil or a CBD-only oil because it is using the entire plant — often called full-spectrum. A full-spectrum oil not only contains CBD, but also the plant's other cannabinoids, including THC, CBN, and more. These cannabinoids all work in unison to make their effects stronger, a phenomenon known as the "entourage effect."
When it comes to the high, a little bit of cannabis oil goes a long way. Edibles have been found to offer effects five times as strong as smoking the same amount. This is because when it's digested, THC passes through the liver and becomes 11-hydroxy-THC. This chemical change brings with it a strong body high. That's why dosing correctly is important.
Once you get the steps down, making cannabis-infused oil at home is easy. You can use household items like a pot, a mason jar, and strainer. Just keep in mind the type of oil you'll choose, along with the best strain of cannabis for your need.
Choosing the right carrier oil
Cannabis is fat-soluble, which means it must bind to fat molecules in order to be digested; it's not possible to make fat-free edibles. The best oil for making cannabis cooking oil is olive oil, coconut oil, or avocado oil.
"Choosing the oil does depend on what the recipe calls for, and how it pairs with what I'm making," says expert Wong, who formerly worked at the California-based edibles and topical company Papa & Barkley, and even flexed her cannabis baking skills on Hulu's Baker's Dozen. "Coconut oil is best for the most efficient THC infusion, but the overpowering coconut scent doesn't go well with everything."
Experts often recommend starting with olive oil because there are added health benefits. This is attributed to the antioxidants and anti-inflammatory properties in olive oil, says Felicity Chen, CEO, and Founder of Potli, cannabis-infused olive oil and edible producer in California with a national line featuring CBD oil. "The good fats in the olive make it a perfect carrier for cannabis," says Chen, who uses locally-produced California olive oil in her infusions.
Choosing the right cannabis strain
For cooking, choose a strain of cannabis that smells good and is fragrant. Chances are, it contains terpenes that would taste equally great in cannabis oil. I used 7 grams of a strain called Grape Pie. It contains my favorite terpenes, Limonene, and Myrcene, which give the cannabis an herbal, fruity, and even sweet flavor.
Experiment with strains you love, either high CBD strains or ones you like, to find out which works best.
How to make cannabis oil
You'll want to choose the ratio of cannabis to oil depending on what works best for you. A 1-to-1 volume ratio of olive oil and cannabis is a standard starting point: 1 cup of oil, and a quarter aka 7 grams of cannabis (when ground up, this equals about 1 cup). If you want a less potent batch of cannabis oil, use an eighth which is 3.5 grams of cannabis and 1 cup of oil.
You can increase the amount of both to make a larger batch, just be sure they're still the same ratio.
Step 1: Decarb your cannabis
Decarboxylating or "decarbing" cannabis is an important step in the edible or topical making process. This step heats up or "activates" the cannabis. When you decarb the cannabis beforehand, the cannabinoids like THC and CBD will work more effectively in the body.
1. Heat up your oven to 240 degrees Fahrenheit.
2. Use a grinder to grind your cannabis into small pieces.
3. Place the ground cannabis evenly on a baking tray.
4. Bake for 30 minutes. Don't exceed 40 minutes — you want to activate the cannabinoids without damaging the terpenes.
Step 2: Steep on the stovetop
1. Set up a double boiler. A double boiler enables the infusion without the risk of burning the oil. If you don't have a dedicated double boiler, you can make your own pretty easily: fill a pot halfway with water and place a heat-safe bowl on top. The bowl should fit in the pot without touching the water.
2. Heat the double boiler on your stove's low setting.
3. Add oil to the bowl or top portion of the double boiler. Once the water in the pot (or bottom portion of the double boiler) is simmering, add 1 cup of oil to the bowl (or top component of the boiler). The water and oil should stay completely separate throughout the entire infusion.
4. Bring the oil to 160 to 180 degrees Fahrenheit.
5. Add the decarbed cannabis and stir.
6. Continue to steep at between 160 and 180 degrees Fahrenheit for 2 to 4 hours, stirring occasionally. Adjust the heat setting on your stove to maintain a consistent temperature for the entire cook time. You may have to add water to the bottom pot or double boiler as the infusion goes on, just in case all the water evaporates over the several hour cook time.
Step 3: Strain the oil
1. Set up your strainer. Place a dish towel on the counter, and sit your glass jar on top. Then place the cheesecloth over the open jar so it's ready to help you strain the mixture. You can use a fine mesh strainer in place of a cheesecloth for this step, but the final mixture won't be completely clear.
2. Carefully remove the oil and weed mixture from the double boiler with an oven mitt.
3. Strain the oil over the cheesecloth or strainer into the jar. Make sure to pour away from you to avoid potential for burns.
4. Repeat the straining process twice for best results.
Step 4: Store the oil
Store the oil in an air-tight container, preferably glass. Glass will help the oil last longer, and it is considered a "neutral" substance, so it won't add anything unwanted to the oil like potential microplastics. You can store it at room temperature in a cool, dark place, like a cupboard.
Light degrades its quality, so the less light, the better. It will last for six months if stored properly.
How to dose your cannabis oil
Dosing edibles is important. It will make the experience more enjoyable if you know what the right dosage is for your desired effect. Edibles affect each individual differently, depending on our genetics, age, gender, weight, and tolerance. Remember that the effect of edibles is much stronger than smoking, because of the chemical process when metabolizing them.
When dosing edible cannabis oil, make sure to start low and build. Our weed oil recipe is made with a 1-to-1 ratio: 1 cup of oil and 7 grams (about 1 cup) of ground cannabis. This ratio estimates that a teaspoon contains three to five milligrams of THC. When you're ready to eat the edible cannabis oil, dose each dish by using a teaspoon of oil. Then wait 30 minutes to an hour and see how you feel.
An important component of dosing is knowing the THCA percentage of the cannabis you're using. In legal markets, these are printed right on the container. Most cannabis contains anywhere from 20% THCA to 35% THCA. The higher the potency, the stronger the cannabis oil.
Remember, despite all the math, this dosing equation is just an estimate. Each batch of cannabis oil will have a slightly different dose, and you'll need to tinker and experiment to find the right dose for you.
Ways to use your cannabis oil
There are many ways to use cannabis oil.
When cooking with it, cannabis oil can be used in healthy recipes or indulgent ones. Replace it with anything you may cook or bake with. This includes savory dishes like stir fries, sauces, and more. "I'll use infused olive oils as a finishing oil over fish, chicken, or grilled vegetables, as a salad dressing oil, and drizzled over vanilla ice cream with a pinch of flaky salt," suggests Wong.
If you use high-quality olive oil, you could even mix it with balsamic vinegar and eat it with bread. "A simple focaccia and olive oil dip are honestly, so delicious and tasty. I also love to drizzle on pasta," says Chen.
A popular and effective option is to bake with it. Replacing any oil in a recipe with weed oil makes for a potent edible in the form of cakes, brownies, or even biscuits. You may have to adjust the heat in your recipe, however, to preserve the terpenes and cannabinoids. Do not exceed 340 degrees Fahrenheit during the baking process. "That will prevent any cannabinoids and terpenes from burning off," says Chen.
Insider's takeaway
Making cannabis oil is easy. You have options with the type of oil you use, as long as it's fat-soluble. You can also experiment with different weed strains to find an effect and flavor you like best.
When eating the cannabis oil, start with a low milligram dose, a quarter teaspoon about 5 milligrams, and then build to see how the oil affects you. It takes time to discover what your sweet spot of dosage is. "Cannabis oils are so versatile," says Wong. "Once you learn the rules of how to infuse and cook with cannabis oil, anything is possible."
