Decarboxylating Cannabis to Activate THC

There used to be so much Snoop Dogg in this post about decarboxylating cannabis.

And why would this post about the delicate and somewhat complicated topic of decarboxylation contain a long ramble from a way too excited, full grown woman, talking about Snoop Dogg?

Because sometimes I put things on the internet in places they really don’t belong.

But, not anymore. It ends today. I’m cleaning up my act and all of the Wake + Bake posts, so that they’re less like a diary for me and more helpful for you.

So if you’ve come back to this post looking for videos of Snoop Dogg’s Sensual Seduction and the Good Good, you can find them on youtube where they belong.

Now, enough about Snoop Dogg already.

Cannabis Decarboxylation

Decarboxylation is absolutely essential to making potent cannabis oils, butters, and tinctures. So let’s get to the point of this article and start by learning what decarboxylation is, and how beneficial it is and how to do it.

What Is Decarboxylation?

We’re going to get a little science-y here, but stick with me. It sounds more complicated than it actually is.

Decarboxylation is simply “a chemical reaction that removes a carboxyl group and releases carbon dioxide (CO2)” [wiki].

When it comes to marijuana, decarboxylation effectively removes the COOH group from the THC-A molecule by releasing H2O (water) an CO2 (carbon dioxide), turning it into the psychoactive THC.

This release of water and carbon dioxide naturally occurs during the drying process and happens instantly when you burn one down.
When making edibles, its easy to take this step for granted.  Decarboxylation happens haphazardly (to some degree) when we heat oil or butter to infuse it with cannabis or when we put that oil into things like Canabanana bread and toss them into the oven.

But if you want fully activated material to use in cannabis capsules, raw edibles, super medicinal tinctures, or activated topicals like cannabis lubricant, decarboxylation will make all of your efforts worthwhile.

Benefits of Decarboxylating Marijuana

There are several reasons why decarboxylating cannabis is so important when making potent and medicinal edibles, tinctures and topical treatments. When you decarboxylate your cannabis at a controlled temperature for the right amount of time you:

  1. fully activate the THC in your material making it readily psychoactive.
  2. don’t risk the evaporation of the antitumoral (cancer-eating), anelgesic (pain fighting) and antianxiety (chilling out) compounds found in cannabis that can be lost if you overcook or overheat your cannabis.
  3. get potent edibles, tinctures and topicals with all of the medicinal value in tact… every time.

Time and Temperature

Ask 10 cannabis cooks how log they decarb for and at what temperature, you’ll likely get 10 different answers.

I’ve been on the hunt to find the most accurate scientific data surrounding this, and if you have something more up to date, I’d love to hear about it in the comments section below. Here’s been the journey so far:
When I found this article at Skunk Pharms Research about decarboxylation, I felt like I was really getting the hang of this whole decarb thing. They shared this handy little chart that shows the rate of decarboxylation of thc at different temperatures:

Decarboxylation THC in Cannabis

via Skunk Pharm Research

But this chart shows data from a “marihuana extract”. Since I’d be working almost exclusively with trim, keif and flower, would my temperatures and times be the same? It turns out… no.

And this widely circulated chart, while helpful as a starting place, doesn’t really have that up-to-date science feel to it. I mean, it’s from the Journal of Chromatography’s 1990 edition and… is that Greek at the bottom?

Enter: Marijuana Growers HQ

…and their amazing decarb experiment… the world really owes them a round of applause.

They tested keif and trim at 240• F for 30 minutes and 60 minutes and had the results tested for several different cannabinoids. Here’s what they found:

Kief

CompoundBefore Decarb30 Min Decarb60 Min Decarb
THCA 24.5% 2.6% .1%
THC 3.8% 25.4% 25.5%
CBDA .6% .3% .3%
CBD 0% 1% .1%
CBN .4% 1% 1.4%
Moisture 0% 0% 0%
Total Cannabanoids 29.3% 30.3% 27.4%

Cannabis Trim

CompoundBefore Decarb30 Min Decarb60 Min Decarb
THCA 6.5% 2.9% .2%
THC .6% 4.8% 6.9%
CBDA .2% .2% .1%
CBD 0% 0% .1%
CBN 0% 0% 0%
Moisture 3.4% 4.5% 0%
Total Cannabanoids 7.3% 7.9% 7.3%

 

Testing provided by SC Labs and experiment conducted by Marijuana Growers HQ

“As you can see from the two charts, 30 minutes was not quite enough to completely decarboxylate either the kief or the trim. At 30 minutes the kief was about 90% decarboxylated but the trim was only about 60% decarboxylated. This difference is likely because the trim had a higher starting moisture content. After 60 minutes however, both keif and trim samples were close enough to 100% decarboxylation for my satisfaction.

So there you have it. 240° F for 60 minutes should be enough to decarboxylate any cannabis with a reasonably low moisture content. For material with higher moisture content, the time can be extended but the temperature should not be increased. If you are concerned about losing organic compounds, lower heat can be used but the time should be extended to compensate.”

It’s Not Over: Enter the Nova

So after gathering all of this information, I was pretty content thinking I was decarbing at the right temp for the right amount of time. Since I don’t have a lab to test in and I didn’t have a tCheck until very recently, I thought that I was really killing it at the decarb game and my edibles were more effective than ever.

But just when I was getting comfortable and set in my ways, Ardent Cannabis released this amazing blog post that explained how my oven method was probably burning off some of my THC.

As a matter of fact, they found that decarbing in an oven can cause a 33% loss of THC.

That’s 1/3 of the active compound in your very expensive cannabis lost due to temperature fluctuations.

They used brand spanking new, lab supported data to test every purported decarboxylation method that I’ve ever heard of… which is quite the undertaking. They also have sweet graphics that break things down in a way easy-to-understand way. I felt like I had woken up from a decarb nightmare and everything was so much clearer and simpler.

Controlled temperatures are key. Controlled temperatures are very hard to consistently achieve in an oven or crockpot or toaster oven.

I don’t like living in that kind of mystery. And I really don’t like wasting a 1/3 of my homegrown organic cannabis just because I don’t know whether or not my oven is going to kick on at the wrong time or the heating element in my crockpot is going to decide to fluctuate.

And so yeah, I couldn’t resist. I had to try one of these babies…

decarboxylation machine

The Nova Decarboxylator aka the Lift boasts 100% THCA to THC conversion and no THC loss. I did a test on the same material I’ve been working with for awhile now and it was truly incredible. It allowed me to use so much less cannabis and cut my dosage almost in half.

I’m writing up a review with a cost analysis (it’s finally here!), but I can tell you for certain that if you decarb and cook with more than a couple of ounces a year, this little machine is absolutely worth the investment.

It’s even more worth it if you use the coupon code wakeandbake for $30 off the Nova Decarboxylator.  Just follow this link or visit Ardent Cannabis for more info.

The Verdict on Decarboxylation

Based on the the results of the MGHQ experiment, I felt confident enough to decarb my trim at 240• F for one hour and my keif for 30 minutes at 240° F. Since I started doing so, my edibles and topicals have seen a dramatic increase in efficacy.

UPDATE: Since I started using the Nova Decarboxylator, I’ve seen an even greater increase in potency and I’ve decreased my dosage by at least a third since making the switch. I’d highly recommend checking it out. You can read more in my review here. 

How To Decarboxylate Cannabis in an Oven

So now you know that decarboxylation is an important step in making cannabis infused products. Thankfully, it’s a super easy process that requires very little input from you.

1. Preheat oven to 240• F (116•C).

2. In a pyrex dish, evenly spread out:

Any amount of Buds, Trim, or Keif

3. Cover with tinfoil (optional).

4. Place pyrex into the oven and bake for 30 minutes for keif or 60 minutes for buds/trim.

5. Remove and allow to cool completely. Use immediately or store in a mason jar in the freezer.

OR…

Put your cannabis in a Nova, push the button. In about an hour, you’ll have fully activated THC without having to wonder or waste weed.

Decarboxylation and the Magical Butter Machine

I get this question really often, so I’m going to use this post to answer it.

Do you have to decarboxylate if you’re using a Magical Butter Machine?

Yes. Yes. And yes.

One of the best things about the MBM is that you can infuse your oil at a controlled lower temperature and keep all of the incredibly medicinal terpenes, cannabinoids and flavonoids in tact. For this reason, you really want to decarboxylate your cannabis before you run it through the Magical Butter Machine.
Also… if you don’t have one of these incredible edible making tools, but really want one, and would also like to save 30 duckets… Here’s a Magical Butter coupon that those fine folks gave me to pass on to you.

You can use the coupon code: wakeandbake at checkout on there as well 🙂

Woah. That’s a whole lot of couponing for one blog post. So now… onto the logistical part…

Much Love,

Corinne

    Thank you so much for this information! I will shamelessly ask for a little more information from you. I have home-grown a Cannatonic 4 strain, hoping for high CBD content, low THC content. I would like to prepare the buds/leaves as coconut oil capsules. The patients I work with need as little THC. So if I understand the process correctly, if I want to burn off the THC and have mostly CBD left, I need to increase the temperature and the time in the oven? Any information greatly appreciated! I am having trouble finding specific recipes to draw out mostly CBD. Apologies to those who are cringing at the thought of sacrificing all that THC, but it’s got to be done! Looking forward to hearing from you, well, after the baby, and the new job!

      Hi Beth,
      I too am interested in your question. Another corollary: If the desire is not to get high, would it make sense not to decarboxylate? If the THC retains the COOH group, they wouldn’t bind to the CB1/CB2 cannabinoid receptors.

      I know it’s been a long time since you posted but I only just read it now. I believe the point is not to try and burn the THC,and likely other valuable items, out of your material but to buy material that is high in CBD and low in THC and work with that. The decarboxylate process converts some CBD precursor to CBD also so it has value for those looking to enhance CBDs. This happens at a lower ratio, so it would appear, than THC. I’m wondering if you came up with any alternate resolution since you posted???

      There is no way to my knowledge to draw out the CBD content of a high THC/low CBD strain of cannabis. any of the charts or information that you see saying otherwise is misinformed, and is actually effectively referring to THC acid being turned into CBN, which is not the same as CBD, but is a partial agonist of the CB2 receptor as well as the CB1 receptor, but with a higher affinity to the CB2. it’s effect is much more sedative then THC, but not the same chemical. CBD actually boils off at a lower temperature then THC, so unless you’re actively distilling the CBD, a higher temperature would actually be taking away more CBD then it would be drawing it out. TBH if you want to work with CBD, find a hemp farm! it’s the most abundant and cheapest source of CBD you’d be able to find.

    I just wrote the first book on the topic, named Cannabis Cocktails. In my research, I discovered that 240 for an hour, covered is just the beginning of the fun.. you have to let the cannabis rest after it comes out of the oven before opening the lid… I wait another 15-30 minutes before opening. Just like when you roast a chicken.. you let it rest before slicing to keep in the juices.
    my book is out in June 2016. Stay tuned. (and on Amazon, B&N, etc…)

    hello. i have been experimenting with decarb and it seems to me leaving it in for even half and hour leaves me with burnt smelling trim which turns into burnt tasting butter… ive tried this at 280°f for 10 min, terrible. at 240° for 20 min ( i took it out early because it was starting to smell burnt and still ended up with burnt tasting oil) and the best ive found so far is at 210° for 20 min.. it seems to activate the most without compromising flavor. have you had any trouble with this “burnt” flavor when decarbing?

    oh! also i forgot to mention when i first tried this it seemed as if all the kief from the trim stuck to the baking sheet so i started “greasing” my sheet with whatever i was making the trim into (butter or coconut oil) and putting the trim on top of that, then wrapping the WHOLE thing in foil… wondering if that might be contributing to the burnt flavor, anddd if theres a better way to save the kief from sticking to the baking sheet, or if youve noticed this happening at all on a pyrex.. as i usually use just a plain baking sheet. thanks so much i have learned a TON from your website!!

      If you want butter–> first heat the butter at low temp. When it starts to bubble and froth then remove with a spoon all the white milky bubbles floating on top. You end up with clear butter oil without any milk protein in it.

      Place your cannabis in a bowl, pour the cleared butter over it, cover it with tinfoil and then place it (butter+ cannabis) at 220-240f for 1 hour in the over. Leave it overnight in the fridge, take it out the next day, put it back in the over to let the butter melt. Now you can strain all the greens from the butter and ur done.

      So basically you can skip one step and add only the strainer step at the end.

    Decarbing Frank’s Gift Cannabis

    I’ve been searching for a reliable way to decarboxylate medical cannabis for a while now, and there seems to be no consensus as to exactly how to do it. Different websites and forums all have a different take on the best temperature to use, how long to heat it, how to prepare it etc. My search finally led me to a British patent for a process of liquid CO2 extraction of resin from cannabis, in which they mentioned how they decarbed their samples and, most importantly, they documented the resulting lab analysis of 4 different amount of time and 3 different temperatures, and the differing results on THCa, THC, CBDa, CBD, and CBN. To me, this is a wealth of information. Here is a link to the patent:

    http://www.freepatentsonline.com/7344736.html

    The 3 temps are in Celsius and translate to Fahrenheit as follows: 105° C = 221° F, 120° C = 248° F, and 140° C = 284° F.

    My takeaway from this long, very technical paper is the following 2 sentences:

    Chemovar producing primarily CBD is 1 hour at 120° C. or 0.5 hour at 140° C.
    Chemovar producing primarily THC to minimise CBN formation, is 1 to 2 hours at 105° C. or 1 hour at 120° C.

    Translation: heat your cannabis in a 120° C (248° F) oven for an hour and you are good to go. Regardless of if your cannabis is high in THC or CBD this will work very well. So I did just that (sort of) and then had the cannabis analyzed at OG Analytical in Eugene, OR. Here is what I did, the lab analysis of cured Frank’s Gift bud, and the decarbed Frank’s Gift bud.

    In the patent, they say it is preferable to dry the herb at a lower temp, then decarb it at a higher temp, but since I had put a pizza stone in the oven to try for a more even temp, I dried it and decarbed it at the same temp.

    5/10/16 I started with 36 g total; removed 1.124 g for analytical lab testing. That left @35 g before removing stems, @ 34 g after removing .9 g of stems.

    9:00 AM I put a 16″ pizza stone (9.5 lbs./4.3 Kilograms) in the oven and preheated to 250° F. I used a Farberware oven probe (laying on the pizza stone) to get an accurate temperature. It showed that it took @ 90 minutes to get up to temp.

    I was aiming for a temp of 250° F, but since my oven fluctuates about 20° F, I could not achieve this. After almost 3 hours of screwing around with the oven, turning the temperature dial up and down, trying to get it to a stable temp, I gave up, and settled on a setting of 245° F.

    I broke up the buds into small pieces (it was very sticky), put it on an aluminum baking sheet, and put it in the oven at 11:45AM. I left it in the oven for 20 minutes to dry completely. It was not sticky at all after drying it. I crumbled up the buds in my hand (very easy) and wound up with mostly powdered bud.

    I returned the baking sheet to the oven and waited until the oven probe said 250° F, which took about 15 minutes. I left it in the oven for another hour, removed it, let it cool down a little, and weighed it. It now weighed 28 g, so it lost about 6 g of moisture (17.6%). I took out 1.15 g for the lab. Here are the lab results:

    Before Decarbing

    THCa = 4.8%
    Δ9-THC = 0.9%
    CBDa = 9.9%
    CBD = 0.6%
    CBN = <0.1%

    After Decarbing

    THCa = <0.1%
    Δ9-THC = 4.8%
    CBDa = <0.1%
    CBD = 9.1%
    CBN = 0.2%

    I am thrilled with the results – all of the THCa got converted to THC, all the CBDa got converted to CBD, and very little of the THC got degraded to CBN. Not too shabby.

    Next time I wouldn't mess with the oven temp. I would just set it at 245° F and leave it alone.

    If you look at Table 5 in the patent, you'll see that there is quite a bit of leeway in time before the THC starts to seriously degrade into CBN, so leaving it in the oven for 1-2 hours at 250° F would not degrade very much THC (4.1% after 1 hour and 6.7% after 2 hours).

    Miscellaneous notes: Franks Gift organically grown outdoors, harvested on 10/4/15, dried in 50% humidity, 70° F temp for 5 days (stems snapped at that point), then placed in 2 quart canning jars with a 62% Boveda pack for curing. It has been in the jar for 7 months.

    I hope this is helpful.

    As for using the magic butter machine, if you put it on high (250 F) for one hour, it actually decarboxylates it in the oil, which means no evaporation of active ingredients. Even using a turkey bag or tin foil when decarbing in the oven is going to lead to a lot of evaporation of both terpene/terpenoids and cannabinoids. Something to consider. This is the most effective way I have tried so far. The rest of the article is spot on though 🙂

Haven’t tried it like this, but did a quick dirty experiment once with high proof booze and just poured the evaporated goo into VG. It worked, but it’s a messy business, TBH. Thus the dry herb vape.

      Hi Gina!

      I’m a tiny bit confused at this question. Weed comes from a plant (cannabis, marijuana) and if you live in a state with recreational or medical marijuana laws, you can get it from your local dispensary. If you don’t, cannabis is an illegal plant, so you’ll have to wait until things change or advocate for the laws in your area to change 🙂

      I hope that helps!

    What to do with the fact that when covered with tinfoil, the temperature inside the bowl won’t go as high as it is supposed to – for example, I get 65 Celsius (149 fahrenhait) when my oven is able to give me 108 celsius (226 fahrenhait) if it wouldn’t be covered with tinfoil.

    So far I’ve only done testing the temperature, but what I’ve read I got the sense that covering will prevent it from smelling a lot – which is crucial in my situation. Should I dare to pop op that oven way way higher to get the insides over 100 celsius? Or is there something I’m missing out?

      So I did my decarbing.

      Started with tinfoil wrapped twice around the plate I had my sweet stuff on. After half an hour, as I had kept my oven at the 105-110 Celsius (around 226 fahrenhait) I decided to check how it was: I popped my thermometer through the tinfoil. It dropped fast to <70 celsius (158 fahrenhait). But, since it now had a small hole (which the rod of the thermometer mainly covered, but a hole still) it started to gradually rise. Too slow, thou, so I increased the temperature of the oven to get the inside-the-tinfoil-temperature to proper degree. With this finetuning, I was able to get it to first fluctuate and then stay between 105-118 celsius. Did that for another 55 minutes (so total time was more than an hour, but since it had been <70 celsius for the first half an hour, I decided it's not worth to take account for (I've seen the graphs and it doesn't do much at that temperature).

      But, I started to freak out about the smell, so I took the plate out and wrapped it another round of tinfoil to cover the hole. I do believe the temperature inside the tinfoil didn't drop too much when I took it out, since it was sealed apart the small hole which I covered up fast.

      After finishing the decarbing I had it cool down for half an hour taken from the oven, with foil on it.

      The end product didn't smell like your regular weed. It didn't seem burned – black, as some have written – but it had become more like brown-green. I'll cook it to oil after the sun sets today.

      So, my take on this is that if you use tinfoil, you have to increase the temperature of the oven quite much to get it right inside the tinfoil, then re-adjust the oven to keep that desired temperature.

      I can imagine only two ways to do this:

      1) pop your thermometer through the foil and after reached the desired temperature, keep it there or re-seal (to prevent smell and loss of some unnecessary stuff – ie. I'm here for the thc), or

      2) do some pre-testing with foil-wrapped plate and see how high you have to set your oven for it to reach proper temperature inside the foil. After finding this, you would have to test if it will rise or stay the same – and if it will rise, you'd have to find another heat setting to use as the 'keep-it-up'- heat.

      Otherwise you'll be decarbing your stuff in (crucially) less than the desired temperature.

    Hi there- quick question, do you recommend decarbing full melt hash for at the same temp for a full hour as well?

    I have the same question; the full melt hash – how long would you suggest decarbing?

    Constantly checking this website for new decarb methods. Can anyone help with a good way to decarboxylate flower without leaving a smell. Live on the first floor of the apartment building and don’t want to be easily pointed out as the ganja house.

      I would also like to know any means of reducing the smell. I live in a mixed household of both cannabis users and haters. The latter mostly complain of the smell, and the agreement to keep the peace is to keep the home odor-free. So far, no one besides Valery has made so much of a peep about it (at least that I’ve noticed). Any feedback would be appreciated, even just a heads up about how smelly and how long it lasts. TIA!

    I found the information in this article very interesting. I have always just decarbed for 30 min. But I will now do it for 60 to see if I can tell the difference. Thanks for all of the great information.

    My latest decarb was at 240 degrees for 1 hour. I am making an alcohol based tincture. I had read elsewhere in High Times that researchers in Holland determined that the optimum decor came at 230 degrees for 110 minutes. http://hightimes.com/edibles/edibles-the-scoop-on-decarboxylation/.

    I imagine variable oven temps and elevation also factor into the equation. The Nova machine would take the guesswork out I suppose, if one could afford it

    I am forced to try decarbing in a nuwave oven which only has preset temp. Ant either 225 or 250 any suggestions? I was thinking 225 for about 50 mins.

    Was experimenting with some of our crop (copperheadcannabis.com) by baking the nugs then adding the cooked flower to items. I had to leave a note to let folks know that you need to make sure you bake it someplace with good ventilation. The flowers have been in the oven for 15 minutes and the house smells like Woodstock or the processing room at harvest time. :s

    I’ll definitely update this post once I try out the baked flowers.

      Guess I should have read all of the posts above instead of skipping to the end. 🙂 The tin foil definitely reduced the odor.

      To start off, I must say I owe Corinne a complimentary gallon size bag of our finest boutique bud for this article and the information within.

      I had never tried baking buds. We don’t sell edibles or extracts with our top-quality product, so I had no reason to. Now that I’ve done so it’ll be a regular occurrence.

      Let me rewind a bit. After reading the rest of the posts on this page and already starting the bake, I put on the tin foil as listed above. After 45 minutes I removed the pan from the oven and let it sit for another 15. Thinking of the intense smell of baking bud, I figured if I was going to eat this I’d better find a food that has a similar aroma to neutralize the pungent smell. I decided on queso dip since the salsa has a similar but offsetting flavor.

      I melted 1/2 cup Velveeta cheese, added 1/4 cup salsa and mixed them up. Then I crushed and crumbled in 3 medium sized baked buds.

      The queso flavor TOTALLY hid the MJ taste. Couldn’t even tell there was any in there.

      I ate about 1/2 of the cheese mix on chips and got pretty baked myself. And not the same way as smoking too much using a water pipe. The high was calm, cool and relaxed. Felt like I was drifting in a cloud.

      Instead of heading out to the garage to weld something together as I normally do after work all I wanted to do was sit on the floor and color with my baby girls. I am grateful it didn’t make me too tired since this bud was a 70/30 Indica/Sativa blend.

      I thank you Corinne for this post! Had I not seen it I would have never tried baking some weed. Now that I have it’ll be something I do again and definitely for friends or those who have never tried edibles.

        Thank you so much Ed! That sounds amazing!

        I’ll take that gallon size bag of boutique bud anytime now 😉

        Much love,

    Hi Corinne,

    I think the new site looks good and is efficient. my question is: decarbing leaf, and ground leaf? Do I use the same time and temp?

    Hi Corinne,
    I have a dehydrator that I am able to adjust the time and temperature on and I am wondering if you, or anyone else on here, has ever used a dehydrator for decarboxylation? I would love some input on this as I am new to Medical Cannabis and would like to be able to make my own tinctures, lotions, and edibles.

    Is there a way to decarb without a NOVA and not in an oven? I haven’t smoked in a very long time because it makes me so paranoid but I need something for anxiety, big time. I am too new to invest in a NOVA and… I don’t think my room mates would be too keen on the smell. I wonder if decarbing in a mason jar in the crock pot could work too?
