How To Decarb Weed For The Perfect Edibles (2022)

There’s a reason people don’t just eat dried cannabis bud. Whether fresh or dried, cannabis won’t get you high unless it’s heated. The act of transforming a sticky herb into a mind-bending medicinal plant relies on a process called decarboxylation. In chemistry terms, decarboxylation is the process of removing an acid (carboxyl) group from a fatty molecule.

But, what is decarboxylation in simple terms? This article tells you everything you need to know about decarboxylation and how to decarb weed properly. First things first, if you want to decarb weed properly, invest in a professional decarb machine.

We recommend buying this incredible all-in-one decarb and butter making package, that will allow you to make professional level edibles while barely lifting a finger:

What Is Decarboxylation?

One way to think about decarboxylation is as an activation. In order to “activate” your herb, you’ll need to break down the components of cannabis resin from fatty acids into their more potent and medicinal formats. Marijuana causes a psychoactive “high” thanks to a compound called tetrahydrocannabinol (THC). This THC, however, is not found on fresh cannabis plants. In fact, the psychoactive only shows up on fresh plants in trace amounts. Instead, trichome-coated flowers are rich in THCA, the acid form of THC.

Believe it or not, THC is actually a breakdown product of THC-Acid. As THCA ages, it loses some of its chemical bonds. When cannabis flowers are dried and cured, small amounts of THCA are converted to THC. Yet, the trace amounts of THC present in dried buds are not quite enough to produce a substantial psychoactive effect.

To speed up the process and ensure that more THCA is converted into its more psychoactive relative, you need heat. Smoking, vaporizing, and otherwise heating the herb unlocks the plant’s psychoactive potential.

The process of converting THC-Acid into psychoactive THC is called decarboxylation. Often abbreviated to “decarbing”, understanding this simple science is useful for herb smokers and culinary artists alike.

Not only does decarboxylation explain why smoking is one of the most popular ways to consume the cannabis plant, but decarbing your herb and concentrates prior to cooking is a surefire way to make for potent and effective edibles.

Knowing When to Decarb Weed

If you’re hoping to get the most from your cannabis, decarbing is essential. Decarboxylation is the only way to achieve a strong psychoactive effect from your herb. Yet, apart from simply taking a lighter to a bowl, where’s when it’s useful to decarb:

  • Prior to making infused oils, edibles, drinks and foods.
  • Prior to making tinctures.
  • Prior to adding cannabis concentrates to edibles and drinks.
  • After making full-extract extractions at home.

While decarbing is necessary to tap into the cannabis plant’s mind-altering nature, a psychoactive experience isn’t always appropriate for everyone.

Fortunately, for those hoping to tap into the healing potential of cannabis without the high, there is some benefit to keeping things raw. The cannabinoid acids found in uncured and unheated cannabis plants may not be as well-researched as THC, but they are not without their benefit.

Early research in the lab suggests that THCA may be useful as an anti-nausea and anti-inflammatory aid. Virtually no human trials, however, examine just how effective THC-acid can be.

Though, many medical patients use fresh cannabis in juices and smoothies to take full advantage of the potential benefits cannabinoid acids may provide.

Do You Decarboxylate CBD?

Just like THC, only trace amounts of activated CBD exists on the fresh cannabis plant. Instead, consumers can expect high quantities of CBD-acid. Like THC-acid, the acid form of CBD is less bioavailable than the decarboxylated stuff.

While there may be many undiscovered benefits of CBDA, it’s the decarboxylated stuff that you’ll find in the tinctures and infused oils often sold online.

The exception is often isolated CBDA crystalline, which is a purified extraction of CBD. Like all cannabinoid acids, CBDA crystalline will transform into CBD when heated via baking, dabbing, vaporization, and smoking.

Those hoping to supplement with the raw extraction, however, may be able to melt CBDA crystals in a warm beverage like coffee or tea without triggering a full decarboxylation reaction.

A full decarboxylation can happen at various temperatures over prolonged periods of time. CBDA crystalline can melt in your average cup of coffee, but that won’t equate to a cup full of CBD. In order to decarboxylate CBDA at such a low temperature, you would need to heat the crystals in your coffee for several hours. With a hotter temperature, like those achieved with a vaporizer, you can expect a fast decarboxylation reaction with any CBDA extraction.

When you’re smoking and vaporizing cannabis, decarboxylation occurs as soon as you add heat. If you’re hoping to decarboxylate before cooking, however, some additional steps are required. But, don’t worry. Decarbing right in your own kitchen is easy!

Decarboxylating your herb prior to cooking is a must for those hoping to make truly high-quality edibles. The good news? You can decarboxylate both cannabis flower and concentrates in your oven. Once the cannabis material has been activated, you can use it to infuse butter, oils, alcohols, fatty beverages, or simply use it as a psychoactive spice the next time you make some pasta. Before diving into the nitty-gritty on how to decarb cannabis, this time table acts as a reference for various common methods:

Table: Decarboxylation Temperatures and Times

TemperatureHeating ModePlant Material TimeKief / Hash TimeCannabis Oil
310FOven10 – 18 minutes5 – 10 minutes
250FHot oil bathUntil bubbles taper off
240FOven50 – 60 minutes30 – 40 minutes
212FBoiling water bath90 minutes90 minutes

Following the timetable works best, of course, when your cannabis material is prepared and handled in just the right way. When decarbing, there are a couple of key things to keep in mind. One of the most important is temperature. The lower the temperature, the longer it’s going to take to decarb your cannabis.

Keep in mind that a lower temperature will allow you to lose fewer terpenes. Terpenes are the pungent oils that color your cannabis with distinctive flavors such as berry, mint, citrus,and pine. There are many medicinal benefits to terpenes; some will successfully relieve your stress while others will promote focus and awareness.

In order to maintain the aromatic integrity of your flower, the following is a general guide to decarboxylation:


How To Decarboxylate Marijuana:

  1. Preheat your oven to 240◦F (approximately 115.5◦C).
  2. Make sure you have an oven thermometer to give you an exact reading of the internal oven temperature. This is very important. Depending on the type of cannabis, your timing may vary, so stay close to the oven to look for signs of high heat and burning. A difference of 10◦ could burn the cannabis.
  3. Line your baking sheet with parchment paper.
  4. Evenly distribute your coarsely ground cannabis on your baking pan. Spacing the cannabis out is necessary to ensure the heat is evenly distributed.
  5. Toast the cannabis for a total of 40 minutes. Check on your herb at 20 minutes and gently stir. Check again at 30 minutes and take the herb out as soon as soon as it begins to develop a light, toasted coloration.

As a general rule of thumb, make sure not to leave the oven door open for too long when checking your cannabis. The heat will quickly escape and you decrease your likelihood of developing an even decarboxylation reaction. Your herb will gradually change color as it toasts. The cannabis should go from a vibrant green to a golden brown or dark green color.

How to Decarboxylate BHO

Just as you can decarb cannabis flower, you can decarboxylate cannabis concentrates. Of all of the cannabis extracts, decarbing butane hash oil (BHO) is perhaps one of the easiest. All you need is a sheet pan, an oven, and some time! Here’s the quick and easy way to decarboxylate BHO.


  • Your desired amount of BHO
  • Baking tray with raised edges
  • Parchment paper
  • Oven mitt
  • Oven thermometer

Directions for Decarbing BHO:

  1. Preheat your oven to 240◦F (approximately 115.5◦C).
  2. Make sure you have an oven thermometer to give you an exact reading of the internal oven temperature.
  3. Line your baking sheet with parchment paper.
  4. Place your crumble, wax, shatter, or budder on the center of your baking sheet.
  5. Bake your concentrate for 20 to 25 minutes, or until it has melted and substantial bubbling has occurred.
  6. You can then let your decarbed concentrate cool to make it easier to handle before mixing it in with melted butter, oils, or other edible creations.

How to Decarboxylate Cannabis Oil

Whether its an RSO or a CO2 oil, you can use an oil or hot water bath to successfully decarboxylate cannabis oils. Fair warning: if using the cooking oil method, be mindful not to heat oils to a boil. This creates more opportunity for burns and accidents.


Directions for Decarbing Cannabis Oil

  1. Place a small heat-proof container of cannabis oil into a larger cooking oil bath (canola oil works well).
  2. Slowly heat cooking oil to 240◦F (115.5◦C) and use a candy thermometer to keep track of the temperature.
  3. As the cannabis oil heats, stir the oil to break up bubbles.
  4. Remove cannabis oil from heat when bubble formation starts to slow down — or leave on heat until all bubbles stop for increased sedative effect.

How to Decarboxylate Kief or Hash

Tips for Properly Decarboxylating Cannabis

In general, decarboxylation is a simple process. After all, when you take your lighter to some ground herb, you can count on a psychoactive experience. When it comes to vaporization and the culinary arts, however, there are some nuances to decarbing to keep in mind. Decarboxylating your cannabis well requires steady heat, a controlled temperature, and time. If you heat your herb too little, the process will not take place. With too much heat, you may accidentally evaporate away the oils, flavors, and THC in the plant material.

The boiling points of the major cannabinoids, aroma molecules, and flavor compounds in cannabis range from 246.2° to 435.2° Fahrenheit. However, boiling points do not always equate to decarboxylation. The ideal temperature for decarboxylating marijuana in an oven is just below the standard boiling points, at 240°F. To properly decarboxylate, it’s useful to decarb at low temperatures for a long period of time.

If you’re using an oven to decarb, you may run into a few complications. It is important to note that most ovens heat in a cycle, so a varying internal temperature can occur. This is especially true in gas ovens and older models with inaccurate thermostats. Fortunately, there are a couple of tricks you can use to ensure that your precious herb is described correctly.

The best way to stay as accurate as possible when decarbing in an oven is to use a digital thermostat and a baking stone. To maintain a more consistent temperature, you can use a baking stone under your baking tray to promote consistency while avoiding opening the oven unless necessary. You can also decarboxylate at lower temperatures to safeguard your herb, as long as you increase your baking time accordingly.

How to Decarb Weed Like an Expert

If you’re a cannabis aficionado, it’s easy to get real scientific with your herb. To help you dial in the perfect temperature for your decarbing process, here is a list of major cannabinoids, flavor molecules, and aroma molecules found in cannabis. All of their individual boiling points are listed. If you’d like to get geeky about it, you can use this information to optimize your decarboxylation process for the particular flavors and aromas you would like to enhance.


There’s more to cannabis than just THC and CBD. Phytocannabinoids are a family of compounds produced only by the marijuana plant. Different cannabis strains can produce varying ratios of phytocannabinoids, giving cultivars their unique effects. Here are some of the most important cannabinoids to know about.
