How to Decarb Your Weed to Make Edibles

By Liam Noonan - 11/29/22

In order to make cannabutter or oil for homemade edible, you need to start by decarbing your weed flower. Decarboxylation is required because it’s the process that activates the psychoactive compounds in cannabis so that you can get a high from the THC. 

If you don’t decarb your weed before consuming it, you won’t get baked. Continue reading to learn more about what decarboxylation is, why it’s necessary for edibles, and how to do it at home using a few different methods.

What is Decarboxylation? 

As mentioned above, decarboxylation is the chemical process that activates the psychoactive compounds in weed.

In other words, a nug straight off the stem contains THCA that needs to be converted into THC. The most common way to convert THCA into THC is through heat. This is exactly what you’re doing when you heat up and take a rip from your dab pen or torch a bowl. To get a little more scientific, the THCA in weed has an additional carboxyl ring withing its chemical structure. The application of heat gets rid of that ring, or decarboxylates, the chemical compound.

 When vaping or smoking there’s enough heat to instantly decarb the THCA compounds in weed and get it ready to absorb into your lungs. It’s also possible for some decarboxylation to happen overtime as your weed is cured and dried after harvest. 

How Temperature & Time Effect Decarboxylation

Proper weed decarboxylation typically occurs between 200-250ºF. It’s important to keep in mind that the various cannabinoids and terpenes found in cannabis react to varying levels of temperature. These compounds can be activated, changed molecularly, or even destroyed when cooked at different levels and amounts of time. 

When it comes to decarboxylation, the key is to go low and slow at around 230-240ºF. This allows you to activate the most THC without destroying the other precious cannabinoids and terpenes.

How to Decarb Your Weed in the Oven

Materials Needed

  • Oven
  • A baking sheet
  • Parchment paper or aluminum foil
  • flower
  • weed grinder (can be hand ground)


  1. Preheat the oven to a temperature of 235ºF
  2. Line your baking sheet with parchment paper or aluminum foil, and grind up your desired amount of bud. Make sure not to grind your flower too fine as this will increase the chances of it burning during the baking process. 
  3. Place the baking sheet in the oven for approximately 35 minutes. You can also use a lower temperature for a slightly longer period of time to better protect and preserve more terpenes if desired.
  4. Once done, remove the sheet and let it cool down for 25 minutes at room temperature. Your weed should now look very light toasted/roasted and feature a golden-brown color. 
  5. As soon as it is cool enough to handle, you can infuse you newly decarbed weed to make cannabutter or oil for edibles.  
  6. If you don’t want to infuse the decarboxylated weed just yet, you can store it inside an airtight glass jar in a cool and dark place until use. 
  7. We recommend using your decarbed weed or cannabutter/oil within 3-6 months to avoid risking some degradation of the THC.

Cannabis Decarboxylation FAQs

1. Can you decarb weed in a microwave? 

We would never advise trying to decarb your weed in a microwave. That’s because you can’t control the temperature and you won’t be able to heat up the bud low and slow. The dry heat from an oven or specialized decarboxylation machine always work best. You can even use a toaster oven at a low temperature if you’re in a pinch. 

2. Can you decarb weed in a crock pot?  

A slow cooker or crock pot are great options for decarbing your weed and infusing it into cannabutter or oil. Check out this article to find out how. 

3. How Long Does Weed Last After Decarboxylation?

It’s not clear exactly how long decarbed weed lasts, but as long as you store it in an airtight jar or container, the THC should stay intact for at least a few months. If you made your decarbed weed into cannabutter, we recommend sealing it up and placing it in the refrigerator. 

4. Can you turn vaped flower into edibles? 

Yes! If you own a dry herb vaporizer like the Storz & Bickel Mighty or Pax, make sure to save the leftover baked bud in an airtight jar. That’s because this weed has already been decarboxylated and is ready to be turned into cannbutter, oil, tea, or even into capsules as an edible.
