Start Extracting


Butter or other oils work well

Step 2

  • Get a pot of water boiling.
  • Sterilize your mason jar in the boiling water, this takes 10 minutes.
  • Let the jar cool a little dry the inside
  • Put your weed in there as well as your oil
  • Replace the lid and place the jar back into the simmering water for 2 hours

Step 1

  1. Figure out which fat you are using
  2. Get your activated weed
  3. Clean it, break it down a little if needed, big nugs will take much longer to extract all the goodness

What fats work?

Cannabinoids are not water soluble which means you need fats or solvents to extract them. Before choosing the fat or oil you are going to use to extract consider how you will use the final product.


  • Olive Oil: can be used to cook veggies, added to pasta, salads and more. Is a good fat for extractions. Has a neutral flavor profile.
  • Coconut Oil: many of the same uses as Olive oil, it can also replace some butter in baking, for infusing honey or making popcorn. A very good fat for extracting, but has it's own flavor profile that is not always wanted
  • Butter: unsalted butter is great for baking, cooking, sandwiches, popcorn, about anything. Is a good fat, however you should read the label and get the brand with the most fat content.
  • Coconut milk: can be use to make extractions as it can have up to 60% saturated fat, the shelf life is not great. When making soups, rice or other dishes, cocnut milk is a great medium for the ABV weed you've stored up.

Think about dosage and start measuring

Now that you know how many mg of THC you require, get it, decarboxylate it, and infuse it into the medium used in your recipe.

For example if you are planning to make a green dragon using a 750 ml bottle of Vodka, that's 24 servings. If your target was 10 mg/serving multiply by the number of servings 24, that means you need 240 mg of THC. If your weed has a THC content of 15% then you need 1600 mg of cannabis, or 1.6 grams.

If you have some less potent weed and wanted to get the dose up to 15 mg/serving then it works out to 360 mg of THC for the bottle of Vodka, to get that you need 3600 mg (3.6 g) of cannabis to make the infusion.

For brownies, the recipe I found makes 16 servings, we'll go for 15mg/serving using that bud with 10% THC. That works out to 2.4 g of cannabis infused in the 1/2 cup of butter. I see lots of people using 1/3 oz or even 1/2 oz to 1/2 cup of butter. These end up being WAY too strong for light users. Avoid those green outs, snack safe.

Oil to Bud Ratio


How much activated cannabis do I need? The dose calculator can be used to figure out how strong your extract is and how much you get per serving based on your recipe.

A good starting point is 5mg per serving. THC % would likely be between 10 and 20%, assume it to be on the high side so you don't underestimate the ratio of THC to oil.

Mason Jar Method


Bring a pot of water to a boil. In a steralized mason jar add your herb, close the jar and place in boiling water. Reduce to a simmer for 2 hours. Remove after 2 hours.

Strain and cool


Place some cheese cloth over a bowl, jar, or other container large enough to hold your oil. Carefully pour the oil, cannabis mix through the cheesecloth into your second container. When done pouring the material, carefully gather the cheesecloth and weed so you can squeeze out all the remaining oils. Store the final product in the fridge.

Decarb & Extract in one step

There may be an easier way. Lately I'm seeing lots of sites and videos that skip the dry decarboxylation of the cannabis and instead decarb while extracting. For this Wet Decarboxylation method you need all of the same materials as you would for the mason jar extraction, however rather than using activated cannabis flower you will use 'fresh' non-decarboxylated buds. 

Break up the flower into fairly small nugs and place in jar, then add your oil or butter. Place the closed jar into a pot of water that is simmering. Let it simmer for 2 hours then remove and strain. This method should work for butter, or oils like coconut, avocado, olive, etc, as well as other fatty materials that can stand up to the heat like sweet and condensed milk for deserts.
