How to Decarb Cannabis and Why it’s Important

Different cannabinoids can be activated in the cannabis plant by treating it in different ways, such as applying heat. This is why it’s important to decarboxylate (or decarb) your cannabis flowers before cooking with them, or why in some circumstances you may wish to leave your cannabis raw.

Most importantly, THC in its raw form is actually a compound referred to THC-A, which has its own benefits, but is not psychoactive. When you apply heat to the cannabis flowers THC-A is converted into Δ9-THC, the cannabinoid responsible for cannabis’ psychoactive effects.

Items Needed:


  1. Preheat your oven to 220°F. Use an oven thermometer to check your oven’s temperature. Your oven may not be accurate, or it’s temperature may fluctuate. You want to ensure that you oven does not get hotter than 230° during the decarb process so that you do not degrade the THC and cannabinoids in your flower by cooking at too high of a temperature.  Adjust the oven temperature down (or up) as necessary.
  2. If you are using a metal baking pan line it with parchment paper, if you are using a glass dish you can skip the parchment paper.
  3. Use you hands to break up the cannabis flowers into small pieces and spread evenly in your baking pan. Cover tightly with aluminum foil.
  4. Bake at 220° for 60 minutes.
  5. Remove from oven and leave covered for 15 minutes to allow any THC and cannabinoid vapors to settle on the flowers.
  6. Use a food processor or a spice grinder to coarsely grind your cannabis flowers. Be careful not to over grind, you definitely don’t want your flowers to become dust.

Congrats! Your flower is now ready to infuse into butter or oil!
