Ever wanted to make edibles but don’t know where to start? Did you think edibles were just too tricky to make? I did too… until I made this beginner’s guide!

I always wondered how to calculate the edible potency. After a lot of trial and error, I stopped guessing. The Canna School has an edible dosage calculator so you can be more accurate with your potency levels.

In this blog, we teach you how to make cannabis-infused cooking oil and have a dosage calculator to help improve your knowledge of the oil!

When making cannabis-infused coconut oil, we like to use refined organic coconut oil.

Here’s the brand we have been using and that has proven to work well for us to this date! Click here if you want to view this organic refined coconut oil on Amazon!

Dosage Guide to Cannabis Oil

The dosage guide to making cannabis oil tends to be a little tricky. You’re going to have a hard time finding the exact potency of the oil that you’re making. It’s also worth noting that since some recipes are going to require more oil than others, you’re going to want to add the recommended amount of oil into the mix (so it’s not too potent). But, it’s up to you.

The Problem

It’s not always easy to know the exact potency of the cannabis that you’re using. Especially since you have activated the cannabis. You should have a rough idea of the THC percentage, but there is still lots of room for error. You also have to keep in mind that if there is a small error in your calculations at the beginning, this error is going to be carried throughout, and it will make your final potency percentage off by quite a bit.

The Solution

We have a great dosage calculator to help you when you’re cooking cannabis oil. Keep in mind, since you won’t have an exact percentage it’s going to be off by a little bit. This tool should help you get a rough estimate for the potency of your oil.

This dosage calculator will automatically update when you fill out your own values. It will work for both kief and cannabis flowers.

The Importance of Decarboxylation When Making Cannabis Oil

For your weed edibles to work the way you want them to, there is a very important step. That step is decarboxylation. All this means is that you need to activate the THC, that way you get the psychoactive effects you intended for. The literal definition of decarboxylation is: “a chemical reaction that removes a carboxyl group and releases carbon dioxide (CO2)” When it comes to cannabis, Decarboxylation removes the COOH group from the THC-A molecule by releasing H2O and CO2, turning it into the psychoactive THC. This step is crucial because it will turn the THC-A molecule into the psychoactive THC molecule. If you were to smoke cannabis this would already be happening naturally when you burn it. But, since in this case, there is no cannabis being burned we need to do this extra step.

How to Decarboxylate

We’re going to be heating the cannabis up to a certain temperature. This is the same thing that vaping cannabis does. It’s possible to use vaped cannabis inside of your weed edibles, and there will be psychoactive effects. However, if you have already vaped that cannabis, you will have already used a substantial amount of the THC. Consequently, you will have to use much more cannabis in the edible If you are using kief, follow the same process as buds, just skip the grinding step. If you’re using cannabis flower, the first step is to grind your cannabis buds. Once you have ground the cannabis, get an oven-safe tray, and cover it in parchment paper. Next, spread the cannabis evenly over the sheet.

What Temperature to Activate The Cannabis?

The temperature that you should be heating the cannabis to is a bit of a debate. There might be better temperatures out there, and you will have no trouble finding people that claim theirs is the best. To their defence, they might be right. But, the temperatures that we have here are backed by some scientific evidence. At the end of the day, you’re going to have a hard time finding temperatures with a noticeably different effect than these. In other words, these temperatures will do the job! 240 degrees Fahrenheit is the number that I’ve had success with. There has also been some good research done by our friends over at Marijuana Growers HQ. They did an amazing decarboxylation experiment and noted their results:

Below are two decarboxylation charts to help give you a reference to the conversion of THCA to THC and CBDA to CBD. You will want to decarboxylate your cannabis anywhere between 30 and 60 minutes.

Cannabis-Infused Cooking Oil

A versatile edible medium that is simple to make.
Prep Time: 45 minutes
Total Time: 8 hours
Course: Appetizer, Main Course, Snack
Cuisine: American
Keyword: cannabis edibles, cannabis-infused cooking oil, cooking oil
Servings: 16 Tablespoons
Calories: 118kcal

Equipment

  • Either a Double-Boiler, Slow Cooker, or Saucepan
  • Oven
  • Baking Tray
  • Parchment Paper
  • Grinder or Scissors
  • Cheesecloth or Strainer

Ingredients

  • 1 Cup Ground Cannabis Flower *Decarboxylated
  • 1 Cup Cooking Oil *Olive and Coconut Oil are most common

Instructions

  • Grind up the cannabis. Preferably grind up the flower/bud as it’s the most potent and will get you a more accurate measurement, but you can include the whole plant. Make sure that it is large enough to not fall through the cloth/strainer. Anything fine enough will end up in the final product.
  • Decarboxylate your cannabis by spreading the cannabis evenly on a baking tray and putting it in the oven for 45 minutes at 240 degrees Fahrenheit. (If you are using trichomes/kief scroll down to image at bottom)
  • With the cheesecloth wrap the ground cannabis and tie it together.
  • Add oil and cannabis into either a slow cooker, double-boiler, or saucepan. For a slow cooker cook on low for 4-6 hours, and stirring it occasionally. Using a double-boiler, cook on low for 6-8 hours ( 8 hours is recommended), and stirring occasionally. Finally using a saucepan, cook on low for 3 hours and stir it frequently, as the saucepan is susceptible to scorching..

    Tip* You can add a bit of water to the mixture to help prevent burning.

    Note: The temperature of the oil should not exceed 240 F no matter which method is used.
  • Strain and capture the oil. If using a cheesecloth do not squeeze, this adds more unnecessary chlorophyll to the oil. Leftover plant materials can be discarded.
  • Finished ! The oils shelf life is at least 2 months! And can be extended by keeping it refrigerated.

  1. This CBD oil is healthier than the normal high calorie oil that we use and it’s benefits extend to reducing inflammation and anxiety. Thank you for sharing.

  2. jeffrey M. cook

    Nice informative site.

  3. I have grown my own pot so how can I guess the THC levels?

    • Hi Diane,
      Usually, when you buy seeds it will tell you the THC percentage of the plant but this is not always accurate. I would estimate that it is in the 10%-20% THC range but you’re going to have a hard time knowing the potency of your oil with those numbers. You could take a tbsp and estimate the potency based on the effects you feel but this is only going to work if you’re experienced with edibles.

  4. After grinding trim do you also take the Kief and spread it out on the baking sheet or just keep it separate?

    • Hi Vanessa,
      You can if you’d like. I usually just use a two-piece grinder or the top half of a 4 piece. That way the kief and flower does not separate. But it’s up to you.

  5. Thanks for the informative article! Having made oil that is two weeks, is there anyway I can increase its potency when making gummies? Thank you. : )

  6. Please excuse my typo (Siri-o) above – having made oil that is ‘too weak’… is there a way I can increase its potency when making gummies? Thanks again

    • Hi Kristie,
      I would recommend that you use the oil that’s too weak in another recipe that requires a large amount of it(sometimes recipes that require 1-2cups are too potent). Then just make a more potent oil specifically for the gummies. 🙂

    Hey! What if I already have cooking hash from a dispensary?

  8. I tried this recipe and I have a few questions. I used a grinder to ground the cannabis, and I tried to get to one cup, but I ended up with a little less. It was still 21 grams, which seems like a lot. Is there an amount in grams that I should be aiming for? I also used a cheesecloth (for the first time in my life) and one cup of coconut oil in a slow cooker on low for six hours. When it was done, I ended up with a half cup of oil, which I used for gummies. I did try to squeeze out the cheesecloth afterward and got a bit more oil, but I know the recipe does not recommend that because of the additional chlorophyll. I am wondering if my results are typical as far as only getting a half cup. Also, it tasted pretty bad so I am looking for advice on that. (Though it was very potent!) I think I ground the flower too fine and it went through the cheesecloth. My guess is that I should wrap the cannabis in several layers of cheesecloth? I might also start with more oil.

    • Hi Libby,
      the number of grams you should use is completely up to you. Play around with the calculator until you find a potency that you like. Infused ingredients like cannabutter or cannaoil are not going to taste great, but there are lots of recipes that can cover it up pretty well. For the cheesecloth, you can do just what you said or you can grind your cannabis a little bit less fine. Either way works.
