Why Decarboxylate Weed?


You probably know that THC (tetrahydrocannabinol), is one of the key chemical compounds in weed that produces psychoactive effects. It’s what gets you high. What you may not know is that there is very little THC present in a live marijuana plant. Growing marijuana plants are high in THCA, (tetrahydrocannabinolic acid), a non-psychoactive compound that will not get you high. It is actually the process of heating up the plant that turns THCA into THC. This chemical reaction is called Decarboxylation, and it is most commonly achieved by smoking.


If you prefer ingesting THC in the form of edibles, your weed needs to be decarbed first in order to be effective. If you are planning to cook with marijuana, you’ll want to put it through this process beforehand in order to activate not only the THC in the plant, but all of its beneficial cannabinoids like CBD, which produces pain-relieving and other medicinal effects. Decarboxylation makes all these compounds more usable, or bioavailable, to your body’s receptors, increasing their effects on the user. It’s a way to get the most out of your weed if you’re going to use it in any variety of edible!

How to Decarboxylate Weed

You’re already decarbing your weed every time you hold a lighter to it. Decarbing for edibles isn’t too much more complicated. The only difference is temperature. Instead of burning cured flowers, you want to bake your bud at a lower heat over a period of 30-40 minutes. Using a lower heat will take longer, but it will preserve the integrity of your terpenes better. Terpenes are the oils in marijuana that give different strains their distinctive tastes and smells. They also have medicinal effects of their own, making some strains better for pain relief or fighting anxiety, while others are more effective at combatting insomnia.


  1. Preheat an oven to 240° F. / 115° C.
  2. Break up your bud into smaller pieces (you can do this with your fingers).
  3. Place the weed onto a rimmed baking tray, trying not to leave much empty space on the tray.
  4. Bake for 30 to 40 minutes, stirring every 10 minutes so that it toasts evenly.
  5. When it is darker in color (a light to medium brown) and has dried out, remove the baking sheet and allow the bud to cool. It should be a kind of crispy consistency.
  6. In a food processor, pulse the cannabis until it is coarsely ground (you don’t want a superfine powder). Store it in an airtight container and use as needed to make extractions.
  7. That’s it! Once you’ve completed this simple process, your weed is now in ingestible form and can be used to make anything from cannabutter to 420-friendly smoothies.
