How To Decarb Weed: Ultimate Guide To Decarboxylate Cannabis

If you want to make your own edibles, tinctures, or oils from cannabis, you need to know how to decarboxylate it.

Decarboxylation, which many people call decarb, is a process that activates the psychoactive compounds in cannabis by heating it. This step is necessary to make sure you get high when you consume the weed despite it being very high thc seeds or not. When you smoke or vape marijuana, you don’t have to worry about decarboxylation because it happens during the heating process.

In this article, we’ll explain how to decarb weed, share tips for doing it successfully, and show you how to use decarboxylated weed in different ways. There’s a lot to learn in this guide, so let’s get started. 

What Is Decarboxylation?

Decarboxylation is the process where heat is applied to raw cannabis to activate its cannabinoids. The duration of exposure to heat is generally between 7 and 60 minutes, depending on the temperature, usually between 200 and 290 °F (104 and 118 °C). 

In raw cannabis, cannabinoids are in their acidic forms, like THCA and CBDA, which aren’t psychoactive. mWhen you apply heat by smoking, vaping, or baking (among a few other methods), a chemical reaction removes a carboxyl group (COOH) from the molecule. A carboxyl group is a carbon atom double-bonded to an oxygen and an OH group.

Removing the COOH releases carbon dioxide (CO2) and transforms the acidic cannabinoids into their active forms, such as THC and CBD. Decarboxylation happens very slowly on its own, but applying a certain amount of heat for a specific time speeds up the process, allowing the molecules to break down and release CO2.

Why Decarboxylation is Important 

With their carboxyl groups still attached, THCA and CBDA cannot effectively bind to cannabinoid receptors, which is why you won’t feel any euphoric effects if you consume raw cannabis. But the purpose of decarbing your weed goes beyond activating it to give you psychoactive effects. Decarboxylation is necessary for the following reasons: 

• Boosting medical benefits: Consuming cannabis in various forms can potentially help with pain, anxiety, and other medical issues. The chemical conversion of weed cannabinoids makes this possible. 
• Making edibles and tinctures effective: If you want to make cannabis brownies or tinctures, decarbing is essential. It ensures that before you cook or mix, the THC is ready for your body to absorb, making your edibles and tinctures more potent. 

5 Methods of Decarboxylation for Cannabis (Step-by-step Guide)

We consider five different ways you can decarb your marijuana buds, along with the materials needed for each method and the step-by-step process involved.

1. Oven Method (Most Recommended)

What you need: 

• Marijuana buds (3.5 grams or 1 eighth)
• An Oven
• Grinder or scissors
• Baking sheet
• Parchment paper
• Oven mitts
• Spatula or spoon
• Airtight container

Step 1: Preheat the oven

Set your oven to 250°F (121°C) and let it warm. This temperature is important for activating the cannabinoids without damaging them.

At 220°F, THCA starts converting to THC. However, CBDA only begins to decarb at 245°F. If you’re working with hemp or CBD-rich strains, you’ll need to bake them for a bit longer since CBDA takes more time to decarb compared to THCA.

Based on a study conducted on oven use for decarbing weed, here is an illustration of the different times and temperatures for decarbing THCA and CBDA in an oven: 

Step 2: Prepare the cannabis

Break up your cannabis buds into small, pea-sized pieces using your hands or a grinder. Don’t grind it so it becomes too fine to prevent uneven decarboxylation and difficulties in straining.

Step 3: Line the baking sheet

Use a baking sheet with raised edges to catch any spillage. Line it with parchment paper to prevent sticking and make cleanup easier.

Step 4: Spread the cannabis

Spread the broken-up cannabis evenly across the parchment paper on the baking sheet. Keep the layer thin and free of clumps for even heating.

Step 5: Bake

Place the baking sheet in the oven and bake for 20 minutes. The exact time might vary based on how fresh or moist your cannabis is. It should change from bright green to golden brown. 

Meanwhile, halfway through baking (around 10 minutes), check the cannabis. You can take it out early if it’s already golden brown and dry. Stir gently to ensure even heating.

Step 6: Remove from oven

After 20 minutes, the cannabis should be golden brown. Carefully remove the baking sheet from the oven.

Let the decarbed cannabis cool completely on the baking sheet. It will be delicate and crumbly, so handle it gently to avoid losing any pieces.

2. Sous Vide Method (Temperature Precision)

What you need: 

• Cannabis buds
• Grinder
• Sealable plastic bag
• Immersion sous vide circulator
• Pot deep enough for the circulator
• Water

Step 1: Grind the herb

Use a grinder to break up your cured weed.

Step 2: Prepare the bag 

Place the ground herb into a sealable plastic bag. Press out as much air as possible before sealing the bag.

Step 3: Fill the pot

Add water to the pot until it is deep enough to fit the sous vide circulator.

Step 4: Set the circulator 

Set the Sous Vide circulator to 95°C (203°F) and attach it to the pot’s side so that the heating element is submerged in the water.

Step 5: Heat the water. 

Wait until the water reaches the set temperature.

Step 6: Submerge the bag and allow it to cook

Place the sealed bag of herbs into the water. It should be fully submerged. Leave the bag in the water for one hour. Most circulators have timers or app controls to help you avoid overcooking.

Step 7: Cool

Remove the bag from the pot and let it cool before using it.

3. Decarboxylation Machines (Less Monitoring, Consistent Result)

A decarb machine is designed to decarboxylate your marijuana and then infuse it into various products for cooking, self-care, pet treats, and more. These modern devices take the guesswork out of making cannabis edibles. They let you know the exact temperature and time your herbs are decarbed, which helps ensure consistent potency and better taste. Here’s the process of using this machine for properly decarbed weed:

Step 1: Prepare the cannabis

Break your buds into small, popcorn-sized pieces. You don’t need to grind the cannabis before using a decarb machine.

Step 2: Load the machine

Place the pieces into the decarb machine’s chamber. Choose the setting based on the type of cannabinoid you want to activate.

Step 3: Start the process

Select the setting and start the machine. The machine will automatically heat the cannabis and perform precision heating cycles based on feedback from its sensors, converting cannabinoids into their active forms Typically, the whole process takes 1 to 2 hours, including warm-up and cool-down time. 

Step 4: Finish and cool

After the cycle is complete and the machine cools down, you will be alerted that the decarboxylation process is finished. With a precision decarb machine, you can simply set it and walk away; there’s no need to monitor it closely. Just press the button to start and return when it’s done.

4. Microwave Method (Time-saving but Risky)

Using a microwave to decarb cannabis isn’t the best method, but if you’re short on time, it can work. Just be careful because the buds can burn quickly. It’s a good idea to start with a small test batch to get the timing right.

What you need: 

• Microwave
• Cannabis buds
• Glass dish

Step 1: Prepare cannabis

Grind or break up your cannabis into small pieces by hand.

Step 2: Arrange in dish

Spread the cannabis evenly in a microwave-safe glass dish.

Step 3: Initiate heating 

Microwave the buds on medium power for about 90 seconds.

Step 4: Stir and heat again

Stir the cannabis and microwave for an additional 60 seconds.

Step 5: Check doneness

The buds should turn golden brown but not be burnt. The downside of using a microwave for decarbing weed is that decarboxylation requires a low and slow process. Microwaves do not provide consistent heating and can lead to uneven decarboxylation and loss of cannabinoids, so you must be extra careful when using them. If you’re not experienced with setting and timing a microwave, it’s best to use an oven. 

Tips for Successful Decarboxylation 

You’ve learned different ways to decarb weed, and we’re sure you’re confident in using any of these methods at home. But here are some tips you should keep in mind: 

1. Choosing the right temperature and time: Proper temperature is crucial to activating the cannabinoids without destroying too many terpenes, which affect the smell and taste. 

Decarbing at temperatures up to and above 300°F (149°C) can cause degradation. It can make the smell and flavor unpleasant. Use a reliable oven thermometer to monitor your oven’s heat to ensure the correct temperature.

2. Proper ventilation is also important: Decarbing cannabis can make your room smell strong and might create a little smoke. Good airflow helps get rid of the smell and keeps things safe.

4. Oven is the best method, but don’t skip baking sheets: Cannabis can stick to baking trays and might burn if not placed properly. Parchment paper or baking sheets help keep it from sticking and make cleaning up easier.
5. Be careful about overheating: If the temperature is too high, the important chemicals in cannabis can be ruined. You want to heat it at a lower temperature, just enough to make it effective. 

We recommend sticking to the temperature specifications of each method of decarbing, which have been explained in previous sections. 

Applications of Decarbed Weed 

After you decarb your cannabis flower, you can apply it in several ways. But remember to start with a small amount and see how it affects you before consuming more. This is because the effects of decarboxylated weed can be stronger than those of cured cannabis. 

1. Infuse into oil or butter: Mix decarboxylated weed with oil or butter for cooking or baking. This is a common method for making homemade cannabis edibles.
2. Make tinctures: Create tinctures by soaking decarboxylated weed in high-proof alcohol for a few weeks. These alcohol-based extracts can be added to drinks or taken under the tongue. Check out our guide for detailed instructions on making tinctures.
3. Make capsules: Put the decarboxylated cannabis into capsules for easy dosing. This is a handy method for those who prefer not to smoke or eat cannabis.
