Welcome to our guide on how to decarboxylate cannabis! Decarbing, or decarboxylation, is an important process that converts THCA into THC, the compound that is responsible for most of cannabis’s psychoactive effects. While raw cannabis contains some THC, it is in the form of THCA, which is not psychoactive. In order to experience the full effects of THC, you need to decarb your weed first.

What is Decarboxylation?

Decarboxylation is the process of applying heat to cannabis in order to convert the THCA in cannabinoid-rich plants into THC. Though the presence of both THC and THCA is beneficial, THC is the only compound of the two that produces psychoactive effects. This means that if you want to feel the “high” associated with cannabis use, decarbing your weed is an essential step.

THC is not naturally occurring in cannabis plants. Instead, it’s produced when a compounds known as THCA and CBDA are exposed to heat. These compounds are found in raw or live cannabis and are non-psychoactive. That means that if you were to eat a raw weed salad, you wouldn’t get high from it. In order for THC (and other cannabinoids like CBD) to be produced, the plant must go through a process called decarboxylation or “decarbing.”

Decarbing exposes cannabis to heat long enough for a chemical reaction to take place, converting THCA into THC. This process can be done using a number of methods including smoking, vaporizing, cooking, and baking. It can also be done using specialized equipment like a decarboxylation machine or oven.

The benefits of decarbing your weed before consuming it are numerous. Not only will decarbed weed get you high (if that’s what you want), but it will also increase the potency of your weed and make it easier for your body to absorb the cannabinoids. Decarbed weed is also better for making edibles since the effects of THC are more pronounced when it’s been through this process.

Why is Decarboxylation Important?

Decarboxylation is important because it activates the THC in cannabis, making it more psychoactive. When cannabis is smoked or vaporized, the heat of combustion decarbs the THC automatically. But if you’re eating cannabis or using it topically, you’ll need to decarb it first.

Cannabis contains a non-psychoactive compound called THCA. When THCA is heated, it loses a carbon atom and become THC, the compound that gets you high. So by decarbing your cannabis, you’re making it more potent.

Not all cannabis is created equal. The THC content of your cannabis will depend on many factors, including the strain, the growing conditions, and how it was processed and stored. That’s why it’s important to know the THC content of your starting material before you decarb it. That way, you can calculate how much THC will be in your finished product.

The process of decarboxylation is simple: all you need is time, heat, and air. You can decarb your cannabis in an oven or slow cooker/crockpot. Just be sure to grind your cannabis finely before you start, and to monitor the temperature carefully so you don’t overdo it and end up with burnt weed.

How to Decarb Cannabis

There are a few different ways to decarb cannabis. The most common method is to bake it in the oven, but you can also decarb it on the stovetop or in a crockpot. The key is to decarb at a low temperature for a long period of time to preserve the cannabinoids.

Oven Method

The oven method is the most straightforward way to decarb your cannabis. Preheat your oven to 240°F (115°C), and spread your ground-up weed onto a baking sheet lined with parchment paper. Bake for 50 minutes, stirring every 10 minutes or so. Remove from the oven, and let it cool completely before moving on to the next step.

Double Boiler Method

The double boiler method is a low and slow way to decarb your weed. This is the best method to use if you want to preserve as many of the plant’s medicinal properties as possible while still decarbing it effectively.

You will need:
-1/2 ounce of ground cannabis
-A double boiler or a heat-safe bowl that fits snugly over a pot of boiling water
-Cheesecloth or a coffee filter
-A stovetop and gas or electric range

Place the ground cannabis in the top of the double boiler or heat-safe bowl. Make sure that the bowl does not touch the water in the bottom pot. Slowly bring the water in the bottom pot to a boil, then reduce the heat so that it is just simmering. Put a lid on the pot, which will help trap steam and prevent evaporation. Allow the cannabis to decarb for 2-3 hours, stirring it every 30 minutes or so.

Once the time is up, remove the top pot from the double boiler/heat-safe bowl and strain the decarbed cannabis through cheesecloth or a coffee filter into a storage container. Press down on the plant matter with a spoon to extract as much of the cannabinoids as possible. Store in an airtight container and use within 2 weeks.

Sous Vide Method

The sous vide method is one of the easiest ways to decarb cannabis. All you need is a sous vide machine, a heat-resistant container, and some water. Simply place your cannabis in the container, seal it, and set the sous vide machine to 110°C (230°F). Let it cook for 2-3 hours, and then remove the cannabis and let it cool. Once it’s cooled, your cannabis is ready to be used.


Now that you know how to decarb cannabis and why it’s important, you can apply this knowledge to your everyday cannabis consumption. By decarbing your weed before consuming it, you can maximize its effects and get the most out of your cannabis experience.
