How to Decarb Weed

What is cannabis decarboxylation?

Cannabis decarboxylation describes the transformation of chemicals by exposing them to heat over a period of time.

The two main cannabinoids in question are THCA and CBDA, which are both found in raw marijuana flowers. You first need to remove a part of the compound, known as a carboxyl, before you can enjoy the wonderful psychoactive capabilities of cannabis.

By decarbing weed, you’re essentially warming up the buds until this reaction takes place. Turning these two compounds into THC and CBD allows them to interact with your body’s receptors, so you feel baked.

This necessary process occurs naturally when you store your buds in air-tight jars, known as curing. The only issue is that it can take a long time for this to complete, and nugs tend to lose their potency.

When you decarb weed, you expedite this chemical reaction by subjecting your marijuana to very high temperatures for a short duration. You can then use the byproduct to create edibles, creams, and oils infused with the therapeutic qualities of cannabis.

The trick to the whole procedure is maintaining the right decarb temp. Crank up the dials too much, and you risk destroying your buds.

Excessive heat can ruin the terpenes in the flowers, which are responsible for each cultivar’s fantastic flavor. They end up smelling terrible and tasting worse.

Maintaining low temperatures between 200–300 degrees Fahrenheit when you decarb weed ensures THCA turns into THC, not CBN. The latter compound sends you to sleep rather than the stars, so it isn’t as desirable to recreational users.

Why decarb cannabis?

There are a host of reasons why you should decarb weed.

For starters, the process reduces the risk of contamination and bacteria growth on your cannabis buds. You can rest assured your stash is safe to consume, plus the extended shelf life means you always have enough.

Cannabis decarboxylation also makes it possible to consume and enjoy the wonderful psychoactive and medicinal properties of marijuana without smoking.

It opened the doors to untold healing potential, without negative side effects, provided you used it responsibly. Medicinal patients can benefit from these incredible compounds in virtually any form: creams, oils, capsules, your favorite dessert, anything.

Another advantage of decarbed weed is that your bud’s effects become stronger. The transformation of THCA into THC is essential if you hope to experience a soaring high. CBDA also needs to convert into CBD before offering you therapeutic capabilities.

Contrary to popular belief, nothing happens to you if you sit down and devour your raw stash of weed. So, without decarbing weed, the infamous pot brownie wouldn’t be any different from a regular one.

Edibles have become synonymous with triggering powerful cerebral and physical euphoria for long durations. They’ve attracted the attention of recreational users around the globe, looking to experience their profound high.

But if you don’t know how to decarb weed properly, your cannabis snacks won’t do anything except disappoint you.

How to decarb weed: 5 methods to decarboxylate cannabis

There are multiple ways to successfully decarb weed from home, with each method offering a unique result. It all comes down to what you plan on doing with your cannabis and what form you would like to ingest it in.

In this section, we take you through five of the most popular methods used for decarbing weed. Below, you’ll find a brief explanation of each technique, along with a step-by-step guide on how to complete them.

Method 1 – In the Oven

One of the most common techniques used to decarb weed is by placing buds in a conventional oven. You’re baking the cannabis for around 30 minutes, depending on how high you set the temperature.

The process is simple, requiring a few items, like:

  • Oven
  • Baking tray
  • Parchment paper
  • Aluminum foil

You can leave your buds intact or crush them. Most experts recommend chopping up your bud before decarbing weed as it helps to optimize the process. Use your hands to pull apart the flowers or pop them into a grinder.

Grinders allow you to collect kief and help you avoid having to clean the sticky residue off your fingers. At the same time, using your hands preserves the trichome’s structure and gives you a chance to bond with your buds.

The oven method is a brilliant option for cannabis chefs looking to infuse decarboxylated plant matter with food. Think weed cakes and muffins or a decadent dessert with a marijuana reduction; you’re only limited by your imagination.

Cannabis Decarboxylation

This technique tends to create a powerful cannabis aroma. While we love the fragrance, it’s worth keeping in mind that your neighbors might smell it too.

Here are step-by-step instructions on how to decarboxylate weed in the oven:

  1. Place a piece of parchment on the bottom of a baking tray.
  2. Spread your crushed buds evenly over the paper, and then cover the tray with aluminum foil.
  3. Set your oven to 230 degrees Fahrenheit and leave your baking tray to cook for 25–30 minutes.
  4. Take out the baking tray and allow it to cool. 
  5. Once at room temperature, you can start incorporating the decarbed weed into your dishes.

Method 2 – In a mason jar

Decarbing weed in a mason jar is a fantastic option for anyone looking to limit the smells coming out of their kitchen.

You still need to use an oven, but the aromatic compounds released by your buds will stay contained inside the jar. Another advantage to this decarb method is that you reduce the risk of burning your flowers during the process.

You’ll need the following items to complete this procedure:

  • An oven
  • An air-tight mason jar
  • Gloves
  • A cloth
  • A baking tray

Once you’ve got all the tools necessary, follow these steps to decarb weed in a jar:

  1. Fill your air-tight mason jar with crushed cannabis.
  2. Wet the cloth with water and then wring it out until it’s slightly soggy.
  3. Place the damp cloth at the bottom of a baking tray and lay the mason jar on the moist material.
  4. Set your oven to 220–240 degrees Fahrenheit and allow the jar to bake for 60 minutes.
  5. Use gloves to remove the container every 15 minutes to shake the decarbing weed about.
  6. Allow your jar to cool down and then either store it or use your bud to create confectionary delights.

Method 3 – Sous Vide

Nothing beats the Sous Vide method if you’re interested in creating edibles regularly or for a business. The only issue with this cannabis decarboxylation process is the high cost of the equipment needed.

Using an immersion circulator gives you full control over the temperature around your buds. The result is perfectly decarbed weed every time.

The following tools are necessary for this procedure:

  • Immersion circulator
  • Vacuum sealed bags
  • A large pot

Grinding up your buds for this decarb technique is vital in ensuring the best results. After crushing your marijuana, follow these instructions:

  1. Fill a vacuum-sealable bag with your raw plant matter.
  2. Pour water into a pot and place the Sous Vide cooker into the container.
  3. Set the temperature to 230 degrees Fahrenheit and allow your cannabis to cook for one and a half hours.

Method 4 – Cannabutter

Decarbing weed in butter is one of the best options available to anyone interested in making edibles. Many enthusiasts like this technique as you eliminate plant matter in your food

The butter melts with the ground-up marijuana, allowing the cannabinoids to bind with the fats. You can then add portions of decarbed weed butter while cooking or baking to give your treats some character.

All you’ll need is the following items:

  • Butter
  • Pot or frying pan
  • A stove

To make decarboxylated cannabutter, follow these steps:

  1. Add even amounts of butter and crushed cannabis to a pot or frying pan.
  2. Melt the contents in the container on a stove.
  3. Set the temperature high but avoid burning the weed.
  4. Pour the melted cannabutter into a jar and allow it to cool.

Method 5 – Boiling

The final cannabis decarboxylation technique on our list is boiling marijuana powder in water. This process is perfect for anyone interested in brewing a psychoactive tea or creating a cocktail.

All you’ll need is:

  • A kettle
  • A pack of disposable tea bags or a steel ball infuser.
  • A mug

Follow these decarb instructions whenever you want to sip on a beverage that packs a punch.

  1. Boil water to 212 degrees Fahrenheit.
  2. Fill a disposable tea bag or infuser with crushed marijuana buds.
  3. Allow the weed to steep in hot water for a few minutes, and then enjoy.
  4. (Optional) Add a bit of butter to the mixture to help draw out the psychoactive chemicals.

What can go wrong when decarboxylating?

THC loss

THC can degrade if exposed to high enough temperatures for a long time. In this process, the THC is converted into a less psychoactive cannabinoid, CBN. 

Degrading small amounts of THC is probably unavoidable for all decarboxylation methods. THC begins changing into CBN at 185°F — below recommended temperatures for decarboxylating weed. 

Like changing THCA into THC, the process starts at a relatively low temperature but doesn’t kick in until higher temperatures.

The smell

Decarboxylation can be unbelievably smelly, especially if the marijuana is uncovered on a baking tray in the oven. 

All of the methods we talked about earlier where the marijuana is in a sealed container, like an oven bag or a mason jar, contains some of the smell. Don’t expect it to be completely odorless, though.

The strength of the final product

Without lab equipment, finding the ideal edible dosing and measuring the amount of THC in the edibles you’ve made after decarboxylation is not realistic. Though this is also true when you smoke weed, you can stop smoking if you feel too high. 

If you overdose from edibles, your body has no choice but to continue digesting, leading to an overwhelming experience.

After you’ve done your decarboxylation and made a batch, try a safe amount and see what effect it has to gauge the strength.

Frequently asked questions about decarboxylation

Now that you know how to decarb weed, it’s only natural to have a few queries or ideas that may streamline your efforts.

Below, we answer some of the most frequently asked questions surrounding this fun and exciting process.

Do you grind weed before decarbing it?

Crushing up cannabis before you decarb weed makes the procedure easier in comparison to leaving them intact. Some choose to break up the buds by hand, while others prefer the advantages of using a grinder. It all comes down to personal preference.

Using your hands tend to prolong the process of decarbing weed, but it also means you won’t damage the structure of the trichomes. Individuals also believe feeling the buds with your hands is an important part of the experience.

In comparison, grinders are fast and clean, meaning you don’t need to wash the sticky residue off your fingers. The other advantage to this method is that you can collect kief and decarb it for stronger edibles.

What happens if you forget to decarb weed?

If you don’t decarb weed before you consume it, you won’t feel any psychedelic effects. Eating raw marijuana is no different from chewing on a few blades of grass or leaves found in your garden.

The high temperatures you expose your cannabis to during this process are vital in changing THC and CBD’s molecular structure. Drying and curing your buds start the decarboxylation of THCA naturally, but it takes a very long time to complete.

Does decarboxylation destroy terpenes?

The process of decarbing weed won’t destroy terpenes as long as you perform the technique correctly.

If you expose your raw buds to excessive heat, you can break down their desirable aromatic profile. The result is weed that smells unpleasant and has a foul flavor in your mouth.

Remember to keep your oven between 200 and 300 degrees Fahrenheit during cannabis decarboxylation to avoid disappointing your taste buds.

Cooking cannabutter

Are you ready to cook with cannabis?

As you can see, decarbing weed is far less complicated than the name suggests. The process is also imperative if you hope to enjoy the recreational and medicinal capabilities of cannabis in any form.

Heat and time are the biggest factors when it comes to the decarboxylation of THCA and CBDA. Temperatures over 300 degrees Fahrenheit can damage your buds, making them taste and smell awful.

There’s almost no limit to cannabis concentrates and what you can make with them. You can use a number of different methods to decarb weed successfully. It all comes down to what form you want to enjoy your marijuana in.

You also need to pick a strain that offers the type of effects you’d like to experience.

Choose from fatigue-busting sativas, relaxing indicas, or get a hybrid for a mixture of both.
Before you start decarbing weed, you’ll need to start growing your own batch of quality marijuana at home. Check out our extensive range of strains at Homegrown Cannabis Co and find a cultivar to match your life.
