While the term may sound complex, it describes the simple process of removing moisture from the flower heads. Decarboxylation is a crucial process for activating the compounds in cannabis. This process converts inactive cannabinoids into their active form and is essential for the psychoactive effects of cannabis products like oils, extracts, and edibles.It might be surprising, but fresh cannabis plants typically contain little to no THC, the compound responsible for the intoxicating effects. This is because cannabis plants produce cannabinoids in their inactive form known as cannabinoid acids. Instead of THC or CBD, the plant's trichomes produce THC acid (THCA) and CBD acid (CBDA).

 

So, what exactly is decarboxylation?

Decarboxylation, also known as "decarbing," is a crucial process that activates cannabis through heat, such as when vaporizing or smoking. During this process, THCA is converted into psychoactive THC, and CBDA is converted into non-psychoactive CBD, among other transformations that affect other cannabinoids in the plant.

How to train Cannabis for higher yields
The chemical formula for the conversion of THCA (tetrahydrocannabinolic acid) into THC (tetrahydrocannabinol) by heat is decarboxylation.

But what happens precisely? The cannabinoid acids in raw cannabis are equipped with an additional CO₂ molecule group, also known as a carboxyl group (hence the name decarboxylation). Sufficient heat releases this additional CO₂ group, resulting in the active cannabinoids we know and appreciate, along with excess CO₂ gas. This process is crucial to achieve the desired effects of cannabis and is a key step in preparing cannabis products for medicinal or recreational purposes.

When is decarboxylation necessary?
Decarboxylation is a critical step when preparing cannabis for edible products or extracts. When smoking or vaporizing, decarboxylation occurs automatically due to the high heat. However, if you intend to create edible products or extracts, decarboxylating the cannabis first is necessary.

While some cannabinoid acids have interesting medical properties, decarboxylated cannabinoids like THC and CBD are better researched and offer a wider range of applications. If you want to consume cannabis to achieve a psychoactive effect and get "high," decarboxylating the flower is essential to release sufficient THC.

Why does cannabis need to be decarboxylated for edibles?
Decarboxylation is an important process in preparing cannabis for consumption, requiring precise control of temperature and time. While cooking uses heat and temperature, most recipes do not meet the specific requirements for effective decarboxylation. Additionally, when preparing edible cannabis products, base ingredients like cannabis butter, oil, or honey are typically used. Decarboxylation of the cannabis occurs first, followed by the infusion of active cannabinoids into the base. The remaining plant material is then removed. This process ensures maximum efficacy of cannabis in the products and allows better control over dosage and effects. Therefore, it's advisable to decarboxylate cannabis before cooking to achieve the desired results.

Oven Decarboxylation of Cannabis Flowers
Decarboxylation of cannabis requires two essential factors: heat and time. The higher the temperature, the less time is needed.

 

  • At 100 degrees Celsius, maximal decarboxylation takes place after about 60 minutes.

  • At 130 degrees Celsius, maximal decarboxylation occurs in a range of 9 to 15 minutes.

  • At 145 degrees Celsius, maximal decarboxylation occurs in a range of 6 to 10 minutes.

  • At 210 degrees Celsius, it takes only a few seconds.


It's crucial not to decarboxylate cannabis for longer than necessary (and not at higher temperatures) to preserve the aromatic terpenes that give cannabis its characteristic flavor. Both cannabinoids and terpenes degrade or vaporize quickly at temperatures above 150°C. Temperatures around 110°C optimize the balance between flavor and potency.

Here, we present the most popular method, using an oven, and three other proven methods for decarboxylating cannabis at home. These methods ensure that you can enjoy cannabis in its active form.

Oven Decarboxylation
Decarboxylating cannabis can be easily done using a conventional oven, making this method very practical. This ensures that your supply is fully psychoactive and ready for cooking or making extracts.

Important Note: This method is suitable for conventional ovens only. Never use a microwave!

Here's how to do it

  • Preheat the oven to around 110°C (the exact temperature depends on your oven).

  • While waiting, roughly break down about 4 grams of your chosen cannabis by hand or with scissors.

  • Place a sheet of parchment paper on a baking tray and evenly spread the chopped cannabis on it.

  • Place the baking tray in the preheated oven for 30-45 minutes.

Decarboxylation - After the cannabis is removed from the oven, it should be golden brown in color and feel crumbly.
  • After removing the cannabis from the oven, it should have a golden-brown color and feel crumbly.


Once cooled, you can grind the THC-rich cannabis using a grinder or a food processor. These ground pieces can be used for cooking or making extracts.

This method ensures that your cannabis is activated and ready to release its effects when used in recipes or extracts. Note that the exact temperature and duration may vary depending on your oven, so it's advisable to keep an eye on the process to avoid overheating.

Decarboxylation in a Mason Jar
T
he baking tray method for decarboxylating cannabis is straightforward but may result in the cannabis odor lingering in your kitchen. With a few additional utensils, you can minimize this odor and improve the air quality in your kitchen, avoiding potential discomfort in your home.

Decarboxylating cannabis in a mason jar is an effective method that leaves less odor in the kitchen.

Here are the steps:

  • Preheat the oven to 110°C. While waiting, prepare an oven-safe glass jar and fill it with approximately 4 grams of your desired cannabis strain. Seal the lid. You can reuse the same jar later for making cannabutter or canna oil, which means less washing up.

  • Dampen a kitchen towel (it protects the jar from overheating). Once the oven reaches the desired temperature, place the dampened kitchen towel on a baking tray and position the jar horizontally on it.

  • Bake the cannabis in the oven for 1 hour. Rotate and shake the jar every 15 minutes while wearing oven mitts.

  • Allow the jar to cool after baking, and store it in a dark, dry place. Crush the cannabis into coarse pieces before using it for making edible products or extracts.

 

Note: During decarboxylation, CO₂ gas is generated. If the mason jar remains sealed, the pressure from the gas can damage the jar. To prevent this, open the lid periodically to release some of the CO₂ gas.

Other Methods for Decarboxylating Cannabis
While the oven is the most common method, it's not the only option for successfully decarboxylating your cannabis. Depending on what you have available, consider the following two methods:

Decarboxylation with the Sous-Vide Method
The sous-vide method involves sealing cannabis in vacuum bags and placing them in a pot filled with water. This method is known for evenly and thoroughly decarboxylating cannabis while protecting it from burns. Plus, there's no smell! For this method, you'll need a
vacuum sealer, a grinder, and a pot.

For even more precision, you can purchase a
sous-vide immersion circulator, a device that heats and circulates water through the pot to maintain precise and consistent temperature. It looks somewhat like an immersion blender. This can be useful if you often decarboxylate large quantities of cannabis.

Here are the steps for the sous-vide method of decarboxylating cannabis:

  • Break down the cannabis into large pieces but not into a fine powder.

  • Seal the ground flowers in a heat-resistant plastic bag using a vacuum sealer.

  • Fill a pot with water. If you don't have a sous-vide immersion circulator, heat the water at a low, consistent temperature. If using an immersion circulator, set the temperature to 95°C.

  • Once the water reaches the desired temperature, place the sealed bag with cannabis in the pot for 1 hour. The bag will fill with gas and rise to the surface, so it's essential to weigh it down. A stable paperclip can be used to secure the bag and insert a spoon through the clip's opening to keep it submerged.

  • Carefully remove the bag from the pot and retrieve the cannabis flowers.


This method ensures even and effective decarboxylation of cannabis and is particularly useful when processing larger quantities of cannabis.

Decarboxylation with a Herbal Infuser
If you have a bit more budget, consider getting a herbal infuser. A
herbal infuser is a handy device that combines decarboxylation, infusion, and extraction into one. This eliminates most of the complexities involved in decarboxylating cannabis, such as temperature management and timing. However, herbal infusers come at a price.

Here's how to use a herbal infuser for easy cannabis decarboxylation:

  • Unscrew the lid of the herbal infuser and remove the glass beaker.

  • Break down your cannabis flowers and place them in the beaker.

  • Cover the beaker with the flat lid and place it in the device.

  • Select the appropriate decarboxylation setting (depending on the THC or CBD concentration of the strain).

  • The herbal infuser automatically calculates the time based on the volume of plant material, its moisture content, and the room temperature.

 

Congratulations! Your cannabis is now effectively decarboxylated and ready for use in infusions or extractions.

Now that you understand the basics of decarboxylation, you can put your knowledge into practice. Carefully select your favorite strain, preheat your oven, and get ready to activate those cannabinoids. With this crucial step, you can then create your own cannabis
butter, oil, tinctures, or other edibles to suit your preferences.

Decarboxylation is the key to getting the most out of your cannabis and ensuring that your homemade products deliver the desired effects. So, what are you waiting for? It's time to start your cannabis adventure!
