How to Decarb Weed: The Ultimate Guide

What is Decarboxylation?

Decarboxylation is a chemical reaction that changes the structure of cannabinoids. When you decarboxylate cannabis, you are converting raw THC-A into active THC. Learning how to decarb weed is useful for anyone looking to enhance the potency of their marijuana.

The most common way to decarboxylate cannabis is by heating it up. The heat speeds up the reaction and smoking or vaporizing marijuana initiates it instantly. However, while decarboxylation is not necessary for all methods of consuming marijuana, it is often used when making edibles or concentrates.

The purpose of decarboxylating cannabis may vary depending on what type of product you are producing, how much THC you want to produce per gram of dried flower, or even the length and quality of your harvest schedule. But no matter what your reasons may be, understanding how to decarb weed is an important step in any cannabis production process

Why Decarb Cannabis

When you ingest raw cannabis, it doesn’t have a psychoactive effect because it has to be converted into a psychoactive compound. That’s where decarboxylation comes in: It converts raw cannabis into a psychoactive compound, usually THC. This is necessary for making cannabis edibles, canna butter, or other cannabis oil.

THC and CBD are powerful healing agents that interact with the body’s endocannabinoid system. This system is responsible for maintaining balance in the body, and when it’s out of balance, we experience pain, inflammation, anxiety, and more.

The raw forms of THC and CBD have some medicinal applications, but they’re not as effective as when they’re decarboxylated. The decarb process removes the acidic/toxic compounds, making these compounds safe for consumption or topical use. So why not just skip the decarb process? Well, those toxic compounds can be harmful if consumed or applied topically without being first removed by the decarb process!

If possible, decarboxylate cannabis only a few days before you intend to consume it.

Temperature and Decarboxylation

When it comes to decarboxylation, the temperature is key. If you’re not careful, you could end up destroying some of the cannabinoids and terpenes in your cannabis. The “sweet spot” for decarbing is between 230-250°F, although different temperatures will activate, alter, or destroy different compounds.

Decarboxylation is the process of activating THCA into THC. This chemical reaction occurs when cannabis is heated to a certain temperature, and it’s necessary for edibles to work properly. Without proper decarboxylation, many of the cannabinoids and terpenes in cannabis will go unused.

When you consider the fact that decarboxylated weed contains activated compounds that are psychoactive, heating up cannabis does make it stronger.

How to Decarb Weed: The Easiest Method (6 Steps)

Decarbing weed to activate the THC and other cannabinoids in the plant makes it possible to enjoy the psychoactive effects of cannabis through edibles, lotions, and other non-smoked or vaped methods. The process is simple, but there are a few things you need to know in order to do it correctly. Here’s our guide on how to decarb weed in the oven:

  1. Preheat your oven to 225 degrees Fahrenheit or 107 degrees Celsius.
  2. Place your baking tray in the middle of the oven, making sure you don’t go too high or low on the temperature settings.
  3. Break up or grind your weed before placing it on the tray, which will maximize efficiency and prevent overheating.
  4. Bake for 45 minutes, then let it cool for 30 minutes before moving on to step 5 below.
  5. Carefully break up any large chunks into smaller pieces using your hands or a tool like a pestle and mortar (or even just by tapping them against something hard).
  6. Finally, put your parchment paper or foil over the top of the now-ground weed and bake for an additional 15 minutes at 220 degrees Fahrenheit or 104 degrees Celsius

Cannabis Decarb Method: The Mason Jar

When it comes to decarbing weed, there are a few different methods that you can use. One popular option is the Mason jar. This method is great because it helps to reduce the smell in your kitchen, and the mason jar will not crack and will remain usable after the oven process.

Another advantage of using the Mason jar is that it retains the same principle of sealing in air as other methods like glass or stainless steel. However, make sure that the cannabis is spread evenly before returning it to the oven so that it cooks evenly.

  1. Preheat your oven to 230 degrees Celsius (that’s about 110 degrees Fahrenheit, for those wondering). Put your baking tray on the middle rack and place a baking sheet on it.
  2. Mason jar: Get your weed finely ground by mortar and pestle, just like with oregano. You can do this right in the Mason jar to avoid spilling. Breaking cannabis into smaller and smaller pieces by hand will also work.
  3. Do not forget to screw on the lid tightly after putting your pot inside.
  4. Hold a fabric kitchen towel under the tap til it is damp, but not soaking. If you don’t want to put a wet kitchen towel in the oven, you can use a shallow oven dish.
  5. Put the damp towel or oven dish in the oven on a low setting followed by the Mason jar placed on its side.

Cannabis Decarb Method: Sous Vide

When it comes to decarbing weed, there are a few different methods that people use. One popular method is using a sous vide machine. This can be done with a circulator, plastic tub, and zip-top freezer bag. The temperature of the water bath should be set at 203 degrees Fahrenheit (95 degrees Celsius).

  1. Finely grind up your cannabis.
  2. Either vacuum seal it or put it inside a zip-top bag.
  3. Leave the weed in the water bath for 90 minutes.
  4. Take it out and let it cool down for 20 minutes before consuming.

Another common method for decarbing weed is on the stovetop. It’s time to learn how to do it on the stovetop with our steps below. This is easy and relatively low-maintenance, but you need to be very careful not to burn your cannabis. Here’s what you need to know:

  1. Start by heating up a pan on medium heat.
  2. Add your weed to the pan and stir frequently.
  3. Be careful not to let the weed burn, as this will produce a bitter taste.
  4. Once the weed has turned light brown, remove it from the heat and let it cool down.
  5. Once it’s cooled down, you can store it in an airtight container for future use.

Can you decarb weed in a microwave?

There is a lot of debate on whether or not you can decarb weed in a microwave. Some people say it’s the best way to do it, while others say it’s not recommended because you can’t control the temperature.

The truth is, you can decarb weed in a microwave, but it’s not the best way to do it. A small toaster oven with a controllable temperature can be used as well but the oven or using an Ardent is our most recommended option.

Now that you have gone through the process of decarbing your weed, it is important to store it in a way that will maintain its freshness. The best way to do this is by keeping it in an airtight jar and storing it in a dark place. You should also try to use it within 3 months, as degradation of cannabinoids and other compounds can occur over time.


Now that you know how to decarb weed, you can enjoy all of the benefits of cannabis without having to smoke it. Enjoy the benefits of your marijuana without any smoke inhalation. You can explore adding the decarbed weed to oils by using infusion devices like the LEVO or the Magic Butter Machine. These tools will help you easily create tinctures or oils for cooking. Enjoy the process and making your own edibles, oils or concentrates at home.
