Decarboxylation: The Simple Way to Decarb your Weed

By  | 

You’re ready to get cooking in the kitchen and wow your friends and family (or maybe just yourself) with your mad cannabis cooking skills. You’re ready to get high during breakfast, lunch and dinner – with some snacks in between. 

There’s just one problem.

You need to decarb your weed before you do anything else, and you’re just not sure how to get started.

Luckily you’re in the right place. With this simple recipe, you’ll be able to have your marijuana decarbed in no time. And I’m even answering all of your most-asked questions about the decarboxylation process.

Why you Need to Decarb Your Weed for Cooking

I get asked this question all the time, so let’s go ahead and answer it first thing. In order for your edibles to get you high, you need to put your cannabis through a decarboxylation or decarbing process.

By slowly cooking your dried buds, you’ll release the THC from the cannabis.

Believe it or not, your raw cannabis contains zero THC. Seriously.

You can google this for days and read about all of the fun science-y reasons behind this process. Or you can just understand that in order for the food you make with marijuana to get you high, you need to decarb your weed first.

Got it?

Good, let’s move on.

The Easy Way to Decarb Your Weed

The decarboxylation can sound intimidating (probably because it’s such a big word), but it’s actually super easy. With just a little big of prep and an oven, you’ll be whipping up edibles in no time.

First, Prep Your Marijuana

dried buds with a handheld grinder

To prep your weed for baking, use a handheld grinder (or your fingers) and lightly grind your cannabis. You do NOT want it to be finely ground – just lightly ground – as if you were going to roll it into a joint.

Next, Bake Your Weed

It doesn’t get much easier than this. Simply spread your ground buds onto a cookie sheet and bake at 250° F for 20 minutes.

You can cover it if you want to, but it’s not necessary.

Finally, Eat Your Weed

Okay – don’t really eat it. But you’re now ready to cook with it.

Answering your Biggest Decarbing Questions

I need to decarb my weed, but I’m afraid of the smell. How bad is this going to smell?

This was one of my biggest fears when I first started cooking with cannabis. There’s too much to cover in a quick answer, so click here to read an entire post on the smell of decarboxylation.

What types of marijuana need to be decarboxylated?

Pretty much all marijuana will benefit from being decarbed or “activated.” 

This means that not just flowers/buds and trim but kief, hash and hash oils as well.

I’m going to use this cannabis to make cannabutter and other edibles that I’m going to be baking/heating. Do I still need to decarb first?

Great question – and YES! For maximum potency of your edibles, you want to activate (or decarb) your cannabis first. 

This is the case even when you’re making slow-cooking infusions like canna butter and canna oil.

What happens if I don’t decarboxylate my cannabis?

Well, you’ll still get some medicinal benefits from the cannabis, but you won’t get as high.

Can I decarb my weed in a toaster oven?

Sure thing! In fact, some people that are nervous about the smell decarb their cannabis in a toaster oven in their garage, basement or even outside. Just be sure that your toaster oven is at an even temperature for 30 minutes before starting the baking process.

Can I decarb my weed using a food dehydrator?

Opinions are mixed on this decarbing process, and it’s not one that we’ve attempted ourselves. Our preference is for higher heat for a shorter amount of time.

If you’re dead set on using a food dehydrator, be sure to further research the process. From what we’ve heard, you need to plan on anywhere from 8 – 12 hours for your cannabis to be fully activated.

    I don’t trust the temp setting on my crockpot…even on the warm setting my food bubbles. Thinking about a MBM machine is this a good investment?

      It would probably be a great investment, but if you’re looking for something less expensive, it would cost less to just purchase a new crockpot with settings you can trust.

    So with all this interest in decarbing weed to get the benefits have you wondered if MANY other plants we use could also gain potency from this? Raw peppercorns and other herb, spice and plant foods in general?

    We tried to decarb our first batch today to make a recipe of chocolate. What I didn’t realize until it was too late my oven turned off after about 20 minutes. now I have a large chocolate bar, (made with crushed cannabis), that has virtually no med. Is there anything I can do with it now? HELP this is an expensive mistake.

      I would try melt it back in a “bain marie” and cook it for a about an hr.

    I never decarb my buds before mAking canna oil and I always get high…no clue why you think u need to decarb long as you hear up cannabis it releases THC.

    • Cannabis Spatula

      You are definitely losing some of the THC by not decarbing it first. But if it’s working for you, go for it. You may find, that by decarbing first, you use less of it in your actual recipe and it lasts longer.

    I’ve tried decarboxylating my cannabis 2 times and I really didn’t feel n e thing. But I think I no what I done wrong. After baking it for 45 min at 220 to 230. Then letting it cool and putting my butter n a pan dump the cannabis in with it then I was heating out for another 30 to 45 min. Am I cooking all the good stuff out?

    Once you decarb will you need to do it again? Say if you decided not to use it for a couple of weeks?

    • Cannabis Spatula

      May 19, 2020 at 5:09 pm

      Nope – you should only need to do it once. Just be sure to store it in an airtight container.

    Do you have to wait for it to cool down before putting lid on and refrigerate? Sorry first to e and just not sure.

    • Cannabis Spatula

      June 9, 2020 at 12:48 pm

      Wait for it to cool and then store in an airtight container. Your decarbed weed does NOT need to be refrigerated. If you turn it into CannaButter, then you would want to refrigerate the butter.

    Why do I need to decarb it to cook with it but I don’t if I decide to smoke it?

    • Cannabis Spatula

      July 27, 2020 at 2:21 am

      When you smoke it, you’re adding heat. Decarbing does the same thing. It’s required to pull out the THC.

      Assuming your marijuana contains 10% THC, and that you follow the instructions exactly, this recipe should contain approximately 85 mg of THC per ounce – or 14 mg per teaspoon.

    Does decarbing not reduce potency of weed?


    May 19, 2021 at 9:02 am

    All i can say is DO WHAT THEY TELL YOU: decarb and make the oil. It is foolproof. I followed the instructions to the letter and made some brownies that would take GODZILLA down. Seriously. Follow their instructions. THEY WORK.
