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?

      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

      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

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