How to Make Cannabis-Infused Oil (Canna Oil): Recipe and Video

By  | 

Cannabis-infused Oil (or Canna Oil) can be a great addition to your Cannabis Edibles Recipes. While CannaButter can be great in baked goods and CannaHoney can be great in your tea, Canna Oil allows you to expand your menu to savory dishes as well – like lasagna, salads and even chili.

How to Make Cannabis Oil (Canna Oil)

First, You Need to Decarb Your Weed

The first thing you’ll need in order to get started is decarbed weed, aka decarboxylated or activated cannabis.

Don’t skip this first step. It’s a must in order for your cannabis edibles to actually get you high. And luckily, it’s a super simple process.

Now You’re Ready to Make Cannabis Oil

In a slow cooker or crockpot, combine 1/2 ounce of decarbed weed and 1 1/4 cups of the oil of your choice.

This can be vegetable oil, coconut oil, olive oil or even avocado oil.

Cook on low for 4-6 hours.

When finished, you’ll need to strain out the marijuana. While some like to use a cheesecloth and strainer, I’ve found that I get the biggest batch of Canna Oil (and make the least mess) when I use a coffee press. (This is the one I love.)

Store your strained Canna Oil in an airtight glass container on your counter or in your cupboard.

Frequently Asked Questions about Cannabis Oil (Canna Oil)

Since not everyone has made cannabis edibles recipes with cannabis oil, it tends to come with several questions. Here are answers to a few of the most popular questions that I receive.

Will Cannabis Oil Work on Salad?

Yes! Some may find the taste to be a little strong if you’re eating it directly on salad without any other flavors, but others swear by it. Personally, I like to use the cannabis oil with other ingredients to make a FLYING HIGH salad dressing. But – yes – Canna Oil will absolutely work on salad.

Will Cooking with Cannabis Oil Smell?

We get this question all the time. As long as you decarbed your weed properly, you shouldn’t notice an overwhelming odor when making Cannabis Oil. In fact, we noticed zero smell when making it in our crockpot. But if you have concerns about the smell of cooking with Cannabis, you can click here to read more.

Which is Better – CannaButter or Canna Oil?

This completely depends on what recipe you’re cooking and what you’re in the mood for. While you’ll probably find that the more common cannabis edibles recipes stick with CannaButter, we find that Canna Oil is just as effective and in fact preferred for some recipes (like for Cannabis Chicken Chili).

Can Canna Oil spoil or mold?

Eventually. Canna Oil can go rancid, so it’s important to keep it in a sealed container and use within 6 – 8 months (although we’ve stretched it to a year before without issue.)

Can Cannabis Oil kill a dog?

Technically, yes. BUT it would take a LOT of weed to kill Fido. Like – a LOT of it. If you’re not using commercial-sized equipment to make your Canna Oil, then you’re probably safe – although we don’t recommend feeding it to your dog.

Can I put Canna Oil in the Microwave?

We don’t recommend making Canna Oil in the microwave (we prefer our low and slow method), but you can put it in the microwave when you’re using it in your cannabis edibles recipes.

    Hi. In trying to produce a very large amount of oil (about 1.25 gallons) I first attempted making a very concentrated amount and then added that to the larger batch. I’m aiming for a very light, easy high (this is for sleep). I can’t tell if it’s worked. The highly concentrated oil was VERY potent; I got super high just from hand-squeezing the oil through the cheesecloth. Do have any thoughts on how to make sure the THC permeates the whole 1.25 gallons?

    If I’m making a smaller batch like 1/4 cup of oil, do you still suggest using the slow cooker or another method?

    I forgot and left the crock on overnight. What impact do you think this will have?

    • Cannabis Spatula

      July 1, 2020 at 3:22 pm

      I would give strain it and give it a taste. It might be a little overpowering / taste burned. You’ll know.

    Is it just the longer the better in that 4-6 hours? or is there a way to know you’re “done”?

    • Cannabis Spatula

      July 6, 2020 at 5:02 pm

      Yup. If you can make it to 6 hours, that’s great. But four hours is probably plenty. Some people sort of forget. 🙂 So 6 hours is fine too.

    If I’m making less than 1 1/4 cup, would you still cook the oil for 4-6hrs. Same question for the decarb of the weed, if decarb less than 1/2 and ounce would you still leave in the oven for 20mins? Thanks!

    • Cannabis Spatula

      July 27, 2020 at 2:21 am

      I would say yes to both – but for the oil, you may want to be closer to the four hour mark. Good luck!

        • Cannabis Spatula

          August 14, 2021 at 1:33 pm

          You can make it on the stovetop, but it’s much easier to do in a slow cooker.

    Trying to make canna oil for the first time. Had 1/3 cup of weed after decarb, added 1/2 cup of coconut oil. Heated in a small pot on my stove, very low, no boil, no bubbles.
    Do you think I can split the amount of oil when finished into to batches of brownie mixes instead of just one?
    Thanks for the help

    • Cannabis Spatula

      September 17, 2020 at 10:09 pm

      Hey! Yes – you should definitely have enough to split into batches of brownie mixes. You’ll want to adjust the amount we recommend as the oil you’re making will be much stronger than our recipe. (We call for 1/2 ounce of weed adn 1 1/4 cups of oil. You used about 2.5 ounces of weed and just 1/3 cup of oil). So depending on the dosage you’re looking for, you should be able to use a very small amount of the Canna Oil you make for each batch of brownies. Happy Baking!

    How potent is your receipe in general? I am wanting to use it for gummies to give as gifts and I want it to give someone a daytime high/energy.

    • Cannabis Spatula

      Assuming that you’re using cannabis with 10% THC, this Canna Oil recipe is 175 mg of THC per ounce. OR 87.5 mg per tablespoon.

    my cannabis is a couple of years old & very dry; does it lose it’s THC content when it’s older & dry? Do I keep everything the same as if using “fresh” buds when infusing? Do you know of a way to keep buds from drying out over time?

    • Cannabis Spatula

      October 28, 2020 at 5:44 pm

      Unfortunately, you can lose 20% (or more) potency when your weed is more than 2 years old. In addition, it may have a very different or “off” taste than what you’re looking for. Worst case is that it’s moldy and can make you sick. Your best bet is to store your weed in an airtight container in a cool dark location and use it (or infuse it) within 6 months.

    Is there any use for spent marijuana left from making cannaoil?

    • Cannabis Spatula

      November 22, 2020 at 4:29 pm

      Yes – do a search on marijuana pulp for some ideas. It’s nearly impossible to predict the strength (and it’s not our favorite taste), but it can definitely be used!

    Hi only have about 2.5grams of cannabis and assuming about 50grams of oil, will it still be okay in the slow cooker or is it too little an amount? Will it still be 4hrs also?

    • Cannabis Spatula

      February 6, 2021 at 7:27 pm

      We have never tried it with such a small amount, so we can’t guarantee results. If it were me, I’d ingest the weed in a different way. But if you do give it a try, be sure to watch it carefully and keep it on LOW. Aim for 4 hours, but stop immediately if you smell a burning smell. Let us know how it turns out!

    Hi my friend is making salve. She left the oil cooking for two days in her crock pot, is that too long? And she didn’t decals it first or does it decarb in the crockpot? Thank you for any input!

    • Cannabis Spatula

      April 13, 2021 at 5:23 pm

      Hi there – It’s definitely important to decarb first. Your friend isn’t going to get the maximum benefit from her weed. In terms of the oil cooking for two days, does it smell/taste burned? If not, she should be good to go. If yes – then I guess it depends on how much of a burned taste she can tolerate.

    Hi, is there an alternative to a slow cooker? I dont have one but will cooking it in a pot on a low heat work too?

    • Cannabis Spatula

      May 17, 2021 at 3:32 pm

      Well – the slow cooker is going to be the easiest method by far! I would take the time to see if you can borrow one or even buy one at a thrift shop. If you can’t go that route, you’ll want to bring a saucepan of water to a simmer on the stove. Place a folded kitchen towel on the bottom of the pan (while it’s still on the stove). Put the cannabis and the oil in a mason jar and close the lid. Place the mason jar in the simmering pot of water for four hours. Be sure to continuously check the water level and add more as needed. You also need to release the lid of the mason jar every hour (it will be hot) to relieve the pressure. When you have the lid off, I recommend stirring the oil as well. After 4 hours, you can strain it per the instructions in this recipe. Good luck!
