How to Decarb Your Weed in 3 Simple Steps

January 19, 2018 6 Comments

Cannabis-infused butter or oil is one of the simplest and most common ways to make medicated edibles. Making infused butter properly has a few steps and can be a little bit tricky. The entire process usually take a few hours, some recipes require even 24 hours if you using a slow-cooker (unless you have the Magical Butter Machine), but once you have a batch of cannabutter, you’ll be able to make any marijuana-infused food within minutes and enjoy your dose of medicine the way you like. 

Decarboxylation: Heat Activates Cannabis

As you may know raw cannabis is non-psychoactive, that's why we have to process it in different ways to be able to consume it and get the best out of this amazing herb. Marijuana becomes psychoactive when couple of things happen to it, heat and time.

The process of decarboxylation, which means heat activates your cannabi, will convert another non-psychoactive component in marijuana (THCA) into a psychoactive one (THC), which will ultimately release the full potential of the psychoactive traits of your strain.

When you smoke your weed the traditional ways, even when you use a vaporizer, the process of "decarboxylation" happens automatically. On the other hand, if you were trying to make edibles, you will be missing the "heating" part, therefore an extra step should take place before making your cannabutter. Decarbing the weed.

Without this process, the herb will have less THC, and eventually less potency and psychoactive capabilities. (Check our blog post Marijuana Effects: THC and CBD, and the Entourage Effect)

On a slightly different note, without decarboxylating marijuana, the little moisture left in your cannabis may cause botulism bacteria to grow in your cannabutters. (Check our blog post 1 Gram Cannabutter Recipe - How to Make Quality Marijuana Butter?)

"Decarboxylation" Process

Decarb weed and the process of transforming THCA to THC can be achieved by heating the raw cannabis on a low temperature in the oven without losing terpene, which are the pungent oils that affect the color of your cannabis and the instinctive flavors such as berry, mint, citrus, pine, etc.

There are many medicinal benefits to be claimed from terpenes; some will successfully relieve your stress while others will promote focus and awareness, so is very important to get the first step right, without exposing the dry material to too a high temperature.

Here is your three step process!

  1. Preheat the oven to 200 degrees Fahrenheit.
  2. Spread grounded buds evenly across baking sheet
  3. Bake for 70 minutes, set a timer!

If you don't have time, you can preheat up to 230 degrees Fahrenheit but bake for only 25 - 35 minutes. I won't recommend lower temperature for this short time, you may not be able to convert all the THCA in the flower to THC and eventually losing potency. With higher degrees however you may risk burning the flower. So make sure to keep an eye on your batch. Checking regularly for even toasting, try not to open oven door fully, keeping all the flavors inside. You can easily use Pyrex bowl or tin foil and cover it to keep all the good stuff inside, while your buds are decarboxylating.

With this decarboxilated cannabis, you can easily start making butter, olive, coconut oil or some other type of infusion. (Check our blog post 1 Gram Cannabutter Recipe - How to Make Quality Marijuana Butter?)

Hello! Does the temperature and amount of time change according to how much weed you are trying to decarb? In the video posted above the woman is using " 1/2 ounce of cannabis" Let’s say I wanted to use an oz.

Hello Jim, you are right!
The older the dried cannabis is, the more it has been decarbed, so it doesn’t need to be too long in oven later. However it takes a really long time before bud completely decarbs naturaly. In that case I would still bake it in the oven for maybe 10-15minutes.

Does older, (obviously dryer) weed decard faster that freshly cured weed. After properly cured weed has been around for 10 months it has lost some of the moisture, therefore I would think that a shorter time in the oven would be called for.
