Decarboxylation guide: How to properly decarb weed

July 8, 2024

Meaning of decarboxylation

Decarboxylation is the process that involves the activation of the psychoactive compounds in the cannabis plants. As it helps in making you feel high when you consume it. The cannabis plant has THCA in it which can lower your chances of getting high. For that, THCA needs to be converted into THC to make you feel high. This process is performed using the flame of a lighter, vape pen, or torch with a dab rig.

THCA in the plant has an extra carboxyl ring in its chemical structure which is removed using that ring. This process is known as de-carboxylates.

How Does Decarboxylation Work?

Decarboxylation occurs through heat. The high temperatures caused when smoking and vaporizing instantly decarboxylate the compounds in the weed. This makes them immediately available for your body to absorb. Some decarboxylation occurs over time when drying and curing cannabis after harvesting a homegrow. The oxygen present in it can contribute to the decarboxylation process to slow it down. This helps in keeping your weed and weed products in an air-tight container which in turn maintains the freshness and potency of the cannabis.

Significance of Decarboxylation for Edibles

To get the usual high from the edibles of cannabis, the process of decarboxylation is necessary. During this time, the decarboxylation process needs to be performed to activate the weed in the edibles before consumption. When making edibles, buds are heated in an oven first. This helps in decarboxylating them. After infusing it in butter or oil you can use it to make cookies or brownies with them. Heating buds in an over before infusion is necessary to activate the THC. It helps in carrying into the infusion and then into the edible.

At What Temperature Does Decarboxylation Occur?

Weed decarboxylation occurs between 200-245ºF. When making edibles it is recommended to heat buds at 220ºF for 30-40 minutes. When compared to smoking and vaping, decarboxylation for edibles is performed at low temperatures to keep cannabinoids and terpenes intact while they are infused. Terpenes evaporate at high temperatures and are considered volatile. They leave undesirable flavors and aromas behind. If you heat the cannabis in an oven at 300ºF, it will burn off the valuable cannabinoids and terpenes present in it.

Decarboxylation temperature chart

Below is the breakdown of THCA into THC, and CBDA into CBD, at different temperatures.

Acid/Cannabinoid	Temperature (ºF)	Temperature (ºC)	Time (in minutes)
THCA/THC	230ºF	110ºC	30
	265ºF	130ºC	9
CBDA/CBD	230ºF	110ºC	45
	265ºF	130ºC	20

 

What Happens if you Decarboxylate for too long?

Heating weed for too long, or at too high of a temperature, can burn off cannabinoids and terpenes. It can make your weed ineffective.

Should Weed be Grounded Before or After Decarbing?

It is recommended to grind weed before you put it in the oven to decarb. This will increase the surface area and create an even consistency, ensuring all your weed decarbs at the same time.

How to Decarb Weed in Oven?

When decarboxylating cannabis in an oven, it’s important to remember that the temperature dial on an oven is more of an average temperature than an exact one. Ovens can fluctuate by 20 degrees so you should keep an eye on the cannabis. If it turns brown too quickly or smells like it is burning you should turn off the oven. It is recommended to invest in an oven thermometer if you plan to cook cannabis regularly. Here is a list of materials that are needed for baking your cannabis:

• Baking sheet
• Parchment paper or aluminum foil
• Oven
• Cannabis
• Cannabis grinder (optional)

Directions to Bake Weed in the Oven

• The process begins by setting the oven temperature to 220ºF. With the help of the oven rack in the middle position, you can bake the cannabis easily. Heating in the middle will ensure an ideal decarboxylation temperature.
• After that, line the baking sheet using good-quality parchment paper or aluminum foil. This will lightly break up or grind the cannabis onto it. Avoid the situation of burning at all costs.
• Continue to heat the weed for 30 to 40 minutes and stir it at least once in between.
• Let it cool down for another 30 minutes at room temperature. By this time the cannabis should look lightly toasted and golden brown.
• After the cannabis has been cooled for such a long time, add the decarboxylated cannabis to butter or oil for infusion. Carefully put the container by packing it in an air-tight container for future use.

Can you Decarb Weed in a Microwave?

It is usually not recommended to decarb weed in a microwave because you cannot control the temperature. The process of decarbing it is very slow and low. The dry heat of an oven is best for performing this process. Using a small toaster oven with a controllable temperature can be used as well.

Quick Tips for Achieving the Perfect Results from Decarbing Cannabis

If you want to achieve the perfect results by decarbing the cannabis you should know that it requires proper attention to detail and precision. Make sure to follow these quick tips to achieve the perfect results from decarbing cannabis:

• Use an accurate oven or decarbing device to maintain a consistent temperature.
• Stick to the recommended time duration to avoid any problems while decarbing it.
• Always seal your cannabis in an airtight container to preserve potency and freshness.

How to Store Your Decarbed Cannabis Properly?

After performing the decarboxylation of your cannabis, make sure to preserve its potency by storing it in an air-tight container. Storing in an air-tight container in a cool and dark place can ensure the freshness and longevity of the decarbed cannabis. When you properly store your decarbed cannabis it ensures to maintain its quality and potency over time. Here are some quick tips to store the decarbed cannabis:

• Humidity and temperature: Keep your decarbed cannabis in a dry and cool environment. Storing it in excessive heat or humid conditions can cause the degradation of cannabinoids. The ideal temperature to store is around 70°F (21°C), with a relative humidity level below 65%.
• Airtight containers:  When you do not store them in air-tight containers, it can result in the degradation of the terpenes and cannabinoids. Storing it in glass containers, or mason jars with rubber seals can be a good option.
• Darkness: Exposing the decarbed cannabis to natural light can degrade the quality of cannabinoids and terpenes. Hence it is necessary to store your decarbed cannabis in a dark place.

When you store the decarbed cannabis properly it can extend its shelf life. Additionally, it can help in maintaining the flavor profile of the cannabis. Once you follow these storage guidelines you can ensure that the cannabis remains fresh and ready for use for various consumption methods.
