What is Decarboxylation & How Do You Decarb Cannabis?

Cannabis edibles are rapidly becoming a popular way to achieve the effects of THC or CBD. However, if you’re interested in creating edible cannabis treats at home, it’s important to understand what decarboxylation is and its vital role in allowing users to feel the effects of ingested cannabis.

What is Decarboxylation?

Decarboxylation, often referred to simply as "decarb" or "decarbing", is a crucial chemical process that activates various cannabinoids within cannabis, such as THC and CBD, making them available for absorption by the body. This process involves applying heat to cannabis flower, transforming the acidic cannabinoids THCA and CBDA into their active forms, THC and CBD. It's a vital step for anyone looking to create edibles, tinctures, or other cannabis-infused products that require activated cannabinoids to be effective.

The two main components of the cannabis decarboxylation process are heat and time. For example, when cannabis flower is being smoked or vaporized, the decarbing process happens when heat is applied from a flame or vaporizer, even without you realizing it. However, simply burning the flower releases the cannabinoids in smoke, so decarbing must take place via a much more precise process before you can use cannabis to create edibles. To decarb cannabis flower for edibles, it is important to retain the active THC and CBD in the flower material by paying close attention to temperature and time, most often with an oven, stove, or microwave.

How Does Decarboxylation Work?

Decarboxylation works by applying heat to cannabis in a controlled manner. When cannabis is heated, the carboxyl group (-COOH) from the cannabinoid acids (THCA and CBDA) is released as carbon dioxide (CO2), converting these acids into their active forms, THC and CBD. This process requires precise temperature control; too low, and the cannabinoids won’t activate, too high, and you risk degrading the cannabinoids and losing potency. This can be done in a variety of ways, either at home or with professional equipment.

Why is Decarboxylation Important?

Decarboxylation is essential for anyone looking to experience the psychoactive effects of THC or the therapeutic benefits of CBD through ingestion. Raw cannabis contains THCA and CBDA, not THC or CBD, meaning it won’t provide the desired effects until it undergoes decarboxylation. Additionally, proper decarboxylation ensures that the full potential of the cannabis is realized, maximizing the strength and efficacy of the final product.

How to Decarb Concentrates

To decarb concentrates, start by preheating your oven to around 200-250°F (93-121°C), aiming for a lower temperature to preserve the terpenes and cannabinoids. Place your concentrate on a silicone mat or parchment paper on an oven-safe dish to prevent sticking and ensure easy collection.

Cover the dish with aluminum foil to keep the aromas contained and prevent the concentrate from being overly exposed to air, which can degrade potency. Bake the concentrate for approximately 20-40 minutes, depending on its initial consistency and the specific type of concentrate.

After it has cooled down, your decarbed concentrate is ready to infuse into edibles, topicals, or capsules, offering a potent and activated blend of cannabinoids for therapeutic or recreational use. Remember, the key to successful decarboxylation is maintaining a low and consistent temperature to fully activate the cannabinoids without degrading them.

How to Decarb Flower

There are a variety of methods in which you can decarb cannabis at home. Using a variety of at home appliances, dive into how to decarb cannabis in the comfort of your home.

How to Decarb Weed Using an Oven

One of the most common decarboxylation methods, and possibly the easiest, involves using an oven. Both temperature and time are easily monitored and controlled with this method. Better yet, you likely have all the necessary tools at home. All you’ll need is your cannabis flower, a meat thermometer, parchment paper, and a cookie sheet.

• Step 1: Preheat the oven to 240 degrees Fahrenheit. It’s crucial to maintain a consistent temperature to avoid burning or under-decarbing the cannab¹is.
• Step 2: Break up the cannabis buds into smaller pieces to ensure even heat distribution. Avoid grinding it into a fine powder as it can lead to overheating of individual parts.
• Step 3: Spread the cannabis pieces on a baking sheet lined with parchment paper in a single layer to allow for even decarboxylation.
• Step 4: Place the tray with the baking sheet and cannabis into the oven.
• Step 5: Bake for 30 to 45 minutes, or until the cannabis turns a light brown color and is dry to the touch.
• Step 6: Cool the cannabis before using it in edibles, tinctures, or other products. Store in an airtight container if not using immediately.

How to Decarb Weed Using a Microwave

A microwave can also be an effective tool for cannabis decarboxylation, but keep in mind that, in many cases, using a microwave isn’t be the preferred method. A microwave’s high temperatures and uncontrollable temperature variances can potentially ruin terpenes and cannabinoids.

1. Step 1: Break up the cannabis into small, even pieces and spread them out on a microwave-safe plate.
2. Step 2: Microwave on high for 90 seconds, then in 30-second intervals, checking the color and dryness after each interval.
3. Step 3: Cool the cannabis once it appears lightly browned and feels dry, then proceed with your recipe or store it properly.

How to Decarb Weed With Water

While this is definitely the most involved method, it’s also one preferred by top cannabis chefs. If you’ve ever heard of the sous vide method of cooking steaks and other meats, it’s a very similar experience. You can easily control the temperature, and time management is fairly simple, as well. Also, the bud has less opportunity to dry out.

1. Step 1: Fill a large pot with water and bring it to a boil. Adjust the temperature to maintain a steady but gentle boil.
2. Step 2: Seal your ground cannabis inside a vacuum-seal bag or a ziplock bag, making sure to remove as much air as possible.
3. Step 3: Submerge the sealed cannabis in the boiling water for 90 minutes to ensure thorough decarboxylation.
4. Step 4: Remove and cool the bag before opening. Your cannabis is now ready for infusion into butters, oils, or other mediums.

Wrapping Up Decarboxylation

While it’s a common assumption that simply adding raw cannabis flower to a batch of brownies is enough to fully activate the THC and CBD, that’s not the case. Knowing how to cook with cannabis is equal parts science and practice.

Decarboxylation is a key step in unlocking the full potential of cannabis for use in edibles and other ingestible forms. Understanding how decarboxylation works, why it’s important, and how to properly execute the process, is fundamental for anyone looking to create potent, effective cannabis-infused products.
