I get a lot of questions about how to make really strong cannabutter and Cannabis infused coconut oil from folks with high tolerances or who need stronger medicine in smaller doses.

Since I generally like to take microdoses of Cannabis (about 10mg or less) throughout the day when I need to medicate, I’ve never really delved into the world of making ridiculously strong Cannabis oil or butter. I realize that some people need stronger medicine, but those people aren’t me, and I don’t have the tolerance to test strong oil without getting really really really messed up, so I never did it.

But a few days ago when I started working on a Cannabis Infused Grilled Cheese post (because, yeah… that happened), I accidentally stumbled on a way to make an incredibly potent, small batch Cannabis oil and butter using decarboxylated hash.

With 2oz of butter or coconut oil and 1 gram of decarboxylated hash, you can make a seriously strong tablespoon of oil or butter in a snap. You don’t need a crockpot, cheesecloth, or a strainer. And it makes no mess! It’s definitely the easiest and strongest Cannabis-infused butter or oil that I’ve ever made.

So yeah, testing this hash butter made me melt into the floor and feel like I just wasn’t going to make it to see another day. Let my mistake stand as a reminder that you really need to be conscious of dosing your edibles. Even an experienced edibles writer sometimes gets hungry and eats half of a grilled cheese without calculating dosage first and spends half of her afternoon asking the farmer to remind her that she’s not, in fact, dying.

On the upside, it was an incredibly cathartic experience that led to some revealing realizations…which I shared in the Cannabis infused grilled cheese post…AND I felt GREAT the next morning. You’ve got to love that weed hangovers aren’t a thing and overdosing on Cannabis sometimes just feels like free therapy.

How Much THC is in One Gram of Hash?

Finding out how much THC is in hash is a little more difficult than calculating the dosage of marijuana. Most hash is comprised of many strains and is much stronger than flower. I checked in with SCLabs to get a sampling of the hash they’ve tested and this is what I figured out:

• Non-solvent hash can range from 30%-over 63% THC.
• This means that one gram of hash can contain anywhere from 300mg-630mg of THC.
• This means that a half of my Cannabis infused grilled cheese was anywhere from 150mg to 315mg of THC…oy vey…

Ten years later, those numbers have held. Bubble hash still tests in that same 30% to 60% range, so I’m leaving the math above alone. What has moved is the other end of the concentrate shelf. In 2016 I wrote that wax could get over 80%. THCA diamonds and distillate now test 90% to 99%, so if you’re working with one of those instead of hash, the number in your gram is bigger than anything on this page.

So How Strong is a Tablespoon of This?

I can’t tell you, and neither can anybody else who hasn’t seen your hash.

That isn’t a dodge. It’s the whole point of the recipe. A gram of hash is somewhere between 300mg and 600mg of THC depending on what you bought, and that’s a spread of 300mg. Any single number I printed here would be wrong for most of the people reading it.

For ten years this post had one number in the intro and a different one down in the recipe card, which is exactly the kind of thing that gets somebody in trouble. Both were true of different batches. Neither is true of yours. So here’s the arithmetic instead. It’s simple, and it’s the only honest answer I’ve got:

1. Find the THC percentage on your hash. If it came from a dispensary it’s on the label. If it didn’t, you’re estimating, and the middle of the range is about 45%.
2. Multiply grams by percentage by 10. One gram at 45% is 450mg.
3. Take off whatever your decarb didn’t convert. An oven run gets most of the way there. It doesn’t get all the way there.
4. Divide by the tablespoons in the batch. This recipe makes four.

Or skip all of that and put your own numbers into the edibles dosage calculator, which does steps two through four and asks how you decarbed so it can handle step three for you.

Whatever number comes out the other end is an estimate of a batch, not a promise about a bite. Hash melts into butter unevenly right up until it doesn’t, and “until it doesn’t” is a judgment you’re making by eye.

I toned this recipe down a little bit because it was way too strong. When I made it, I used 1g hash to 1oz oil or butter, so a 1 to 1 ratio does technically “work”, it’s just really really really really really really really really really really really strong. I cut it in half for those of you who would like to function at a base level (walking, talking, etc).

If you need to make your medicine stronger, you can get a lot of hash into a small amount of butter or oil. The flip side of that is how easy it is to end up with something much stronger than you meant to make, which is the mistake at the top of this post.

How to Decarb Hash

The ingredient list says decarboxylated hash, and for ten years this post never told you how to do that. Somebody asked me in the comments of my decarb post and I told them I wasn’t sure. So let’s fix that.

Hash isn’t flower. There’s no plant material in it, which is the entire reason it works in this recipe, and it’s also why it decarbs faster and why it behaves differently in the oven. It softens, then it melts. A baking sheet is the wrong container.

• 240°F. Same oven temperature I use for flower and for kief.
• 30 to 40 minutes. For comparison, my decarb post runs flower for 60 minutes and kief for 30. Hash sits with kief, not with flower.
• Break it up small first, and spread it thin. Clumps decarb on the outside and stay raw in the middle.
• Cover it. A sealed mason jar, or a glass dish with a lid. This isn’t fussiness. Terpenes come off as vapor at these temperatures, and an open tray lets them leave the building. A lid keeps them in the vessel, and the vessel is where your butter is headed next.
• It’s done when it stops bubbling. Those bubbles are CO2 coming off the THCA. When the surface goes still, the reaction has run out of acid to convert. That’s a better endpoint than a timer, because your oven isn’t my oven.

Where these numbers come from. I’ve never run my own lab tests on hash the way I did on flower and kief, so I went and read what the solventless people do. The Press Club puts solventless extracts at 225-240°F for 35-50 minutes in a sealed jar. Trim Leaf says 220-240°F for 30-45 minutes. Lowtemp Plates says 220-250°F for 25-30 minutes and gives the bubbling cue. Three sources, one window, and it lines up with the 240°F I was already using.

You’ll also find charts telling you to run hash at 300°F for 10 minutes. I wouldn’t. THC starts converting to CBN at the top of that range, and CBN is what turns an edible sedating rather than whatever you were going for.

If your concentrate came as RSO or FECO, or the label says THC rather than THCA, it’s already decarbed and this step is behind you.

Hash Infused Butter or Hash Infused Coconut Oil (Spicy Italian)

In a double boiler or makeshift double boiler over medium high heat, combine:

2oz (4 Tablespoons) organic butter or coconut oil

1g organic bubble hash (decarboxylated)

1 tsp Italian herbs (optional)

A generous pinch of red pepper flakes (optional)

1/2-1 clove garlic (optional)

As butter or oil melts, whisk until all ingredients are combined and hash melts into the butter. Cook for about 20-30 minutes until all of the hash has dissolved into the butter and the herbs are fragrant (if using). Remove garlic.

What If I’m Using Flower Instead of Hash?

Then this is a different recipe and this post won’t serve you very well. The thing that makes hash butter easy is that hash dissolves and flower doesn’t, so with flower you’re back to a long infusion, a strainer, and all of the mess I just told you you could skip.

That’s the case where an infusion machine actually earns its counter space. It holds a temperature instead of swinging around one, which matters a lot over a long flower infusion and matters very little over thirty minutes of hash melting into butter. I use a LĒVO for flower. I don’t use it for this.

Once there’s a jar of this in your fridge the question becomes what to put it in, and that’s mostly what the Wake + Bake cookbook is for.

Disclaimer: This is not intended as medical advice. I’m not a doctor. I’m also not a lawyer and can’t defend you if you get busted trying to make this recipe in a state that still considers possession or cultivation of Cannabis a criminal act. I don’t agree with this law, but I’d never advocate that you break it. Jail would suck. Instead, I strongly advise that you work to change the law in your state or nation by supporting and being active in grassroots organizations that are trying to legalize Cannabis in your area (they’re everywhere). This recipe is heretoforth only intended for people who live in states or countries where medical or recreational use of Cannabis is legal, who are 21 and older, of sound mind and who understand that operating heavy machinery (cars, trucks, planes, etc.) under the influence of any intoxicant, including marijuana, is incredibly dangerous, immature, and wholly stupid. Please don’t ever eat and drive. Support public transportation or use the two legs that evolution gave you and walk your sweet ass wherever it is that you need to go.

Much love,

Ingredients

  

• 2 oz Organic Butter or Coconut Oil (4Tablespoons)
• 1 gram Organic Bubble Hash (decarboxylated, see the decarb step below)
• 1 tsp Italian Herbs (Optional)
• Pinch A Generous Pinch of Red Pepper Flakes (Optional)
• 0.5-1 Clove Garlic (Optional)

Equipment

• Double boiler
• Whisk

Method

 

1. Decarb the hash. 240°F for 30 to 40 minutes, broken up small, in a covered glass dish or a sealed mason jar. It is done when it stops bubbling. Full detail is in the post. Skip this only if your concentrate was already decarbed (RSO, FECO, or a label that says THC rather than THCA).
2. In a double boiler or makeshift double boiler over medium high heat, combine all of the ingredients.
3. As the butter or oil melts, whisk until all ingredients are combined and the hash melts into the butter.
4. Cook for about 20-30 minutes until all hash has dissolved into the butter and the herbs are fragrant (if using).
5. Remove garlic.

Notes

Dosage: This makes 4 tablespoons. How strong each one is depends entirely on the hash you started with, which can run anywhere from 30% to 60% THC. Run your own numbers through the edibles dosage calculator rather than borrowing a figure from somebody else’s batch. Whatever it gives you is an estimate for the batch, not a guarantee about any one spoonful.
