Decarboxylation happens when cannabis is heated, such as when inhaling. This process makes the compounds in cannabis immediately absorbable by the body. Some decarboxylation can also occur over time during the drying and curing of cannabis after harvesting. To slow down this process, store your cannabis products in an airtight container to maintain their freshness and potency.

Decarboxylationfor cooking

When decarboxylating cannabis in an oven, it’s important to remember that the temperature dial on an oven is more of an average temperature than an exact one.

Ovens can fluctuate by 20 degrees, so keep an eye on the cannabis. If it turns brown too quickly or smells like it’s burning, turn down the oven. An oven thermometer is a good investment if you plan on cooking with cannabis regularly.



  • Baking sheet

  • Parchment paper or aluminum foil

  • Oven

  • Cannabis

  • Cannabis grinder (optional)



  1. Set the oven temperature to 245ºF, with the oven rack in the middle position. Ovens are hotter at the top and cooler at the bottom, so heating in the middle will ensure ideal decarboxylation temperature.

  2. Line the baking sheet with parchment paper or aluminum foil, and lightly break up the cannabis onto it, but not too fine, to avoid burning.

  3. Heat for 30-40 minutes, stirring at least once.

  4. Let cool for 30 minutes at room temperature. The cannabis should look lightly toasted and golden brown.

  5. When cool enough to handle, add the decarboxylated cannabis to butter, oil, or another base for an infusion, or carefully put it into a storage container for future use.
