Cannabis Butter From Vaporizer Leftovers

Introduction: Cannabis Butter From Vaporizer Leftovers

Use the spent material from a vaporizer to create one cup of potent and versatile cannabis butter.

One needn’t throw away vaporizer leftovers. The heated plant material does not lose all of its potency in the vaporization process, and it’s easy to make use of those leftovers by dissolving the cannabinoids into a fatty mixture like oil or butter.

This recipe uses only butter, water, and ground marijuana. Potency will vary based on the strains that comprise the leftover vaporizer material, how spent the plant materials is (ie darkness of the roast), and individual tolerance level.

Check your local laws to determine if this project is legal where you live. I reside in Colorado, a state in which recreational marijuana has been legalized for adults over the age of eighteen. However, laws governing the sale, distribution, and use of marijuana vary by state as well as internationally. Use sound judgment, make good choices, and always use care when consuming edibles of unknown potency.

Step 1: Ingredients and Tools

  • (2) half-cup sticks of unsalted butter
  • (4) grams of vaporizer leftovers*
  • (1) gram of ground fresh cannabis
  • (3/4) cup of water
  • cheesecloth

  • stovetop range with a low heat setting
  • 1 quart saucepan
  • wire mesh strainer
  • 2-cup round dish
  • refrigerator

*Vaporizer leftovers vary in potency. A potent strain will yield more potent leftovers. The amount of heat applied from the vaporizer will determine how dark your roast looks: lighter color generally indicates that you’ll get more potency whereas a darker color indicates that you extracted the potency with the vaporizer and may need to supplement with additional leftovers or the addition of fresh herb.

Step 2: Mix, Heat, and Wait

  • Add the butter, ground herb, and water to the saucepan.
  • Set the burner to the lowest heat setting.
  • Set a timer for five or six hours, then wait.
  • Stir occasionally, making sure to scrape any errant bits of material from the sides of the pan.

The low heat setting ensures that you don’t inadvertently overheat the THC, thereby compromising its potency. Because THC is not water-soluble and the dried herbs float, the addition of water to the mixture is solely to float the ground herb away from the heat source.

Low and slow is the way to go to ensure that the THC bind with the lipids in the butter.

Step 3: Strain and Chill

After your mixture has simmered for several hours, it’s time to strain it to remove the solids from the mixture.

To do so, simply lay a square of cheesecloth over your mesh strainer. Secure the sides with one hand while pouring the mixture over the cheesecloth. The warm butter and water will pass through the cloth and mesh, leaving behind a buttery pile of damp solids. Use a spoon to squeeze out the remaining liquids, and you should end up with a dish of greenish-brown butterwater.

There may be some fine material in your cooling dish, and that’s okay. It’ll rinse off after the mixture separates and cools.

Let the mixture cool at room temperature, then cover it and pop the dish into the fridge for several hours to help the fats solidify. I recommend leaving it overnight to solidify. If you must hurry, do not use the freezer. Instead, fill a larger dish with cold water and place your smaller buttery dish into it to speed up the chilling process.

Step 4: Drain and Rinse

Behold the power of specific gravity!

You’ll notice that the fats all rose to the top of the dish, where they solidified into a puck of butter. The water settled to the bottom, and any tiny bits of floating herb floated above the water but below the butter.

To drain the water, I use a chopstick to poke a hole along one edge of the butter puck and another on the opposite side. Then simply pour the water out and discard it.

My butter puck has little brown bits of floating herb stuck to it. A quick rinse under cool water washes that right off, and you’re left with a clean batch of cannabutter.

Step 5: Finished Product

You should be left with just under 2 cups of clean, green cannabis butter.

Use it when baking, as a topping on toast, mixed into tea, or eat it plain. For the first few attempts at this recipe, pay close attention to the potency and use more or less vaporizer leftovers as needed.

Ingested marijuana takes longer to reach your bloodstream than vaporized marijuana. It can take anywhere from 30-90 minutes to feel the effects. If you have just eaten a heavy meal, it will take longer for the THC to reach your bloodstream. Conversely, if you haven’t eaten for several hours, the THC will hit your bloodstream faster. The psychoactive effect lasts longer when THC is ingested (up to eight hours) so don’t drive, operate heavy machinery, or hang out with your in-laws in the hours immediately following ingestion.

Now when it says simmer for 5 or 6 hours. What temp is that? Anyone got a bead on exact temp and exact time frame please answer.

There is! Read this thread, drop down to multiple extractions. I have not tried the washing method as I like the taste. I do mine in a crockpot.

is there any way to make duff butter more palletable? It’s so nasty tasting! The mb2 does it in two hours.

1. 5-6 hours is overkill. After 1-2 hours all of the THC will be detached by heat and absorbed by the butter fat. Don’t waste your time with 6 hours of simmering. 2. This is an incredibly light dosage. Vaped marijuana only has around 20-30 percent THC content left. Personally if I were using two sticks of butter, I would add around a half to a full ounce of vaped weed. That would only be the equivalent of about 4.5 – 7 grams of fresh flower. 3. Make a little sachet out of the cheesecloth and tie the material inside. This will save you the straining step and probably some of the waste that goes along with pouring butter. 4. Water, water, water. This is a good water recommendation, usually about 2 parts fat, one part water. Once the butter is cooled and separated, melt down the butter and add water a second time. After this is cooled, melt it and add fresh water a third time. This will take more of the burnt taste out as well as remove almost all impurities. This is not as important with fresh flower as it is with vaporized. Hope this helps!

Cooking and baking with vaped weed

Most stoners know how to conserve weed when times get hard. The most broke among us can relate to gathering small roaches together or scraping the bowl of our bongs in a desperate attempt for a toke. What most don’t realize is that vaped weed leaves behind a similar resin that you would find in any used bong or pipe only it’s much cleaner and purer while also being trapped inside semi-burnt plant matter remains. While that may come as a shock to those, who pride themselves in the efficiency of their vapes to extract as much of the THC as possible it is true that even the very best vapes will leave behind a bit of wasted THC.

What is vaped weed?

Vaped weed is vaporizer leftovers. It is the sticky, grainy brownish substance that is left behind after you have run some herb through your vaporizer. Generally, vaped weed will still contain anywhere from 20%-30% of the THC that was in the bud before it was vaporized.

Can you smoke vaped weed?

The answer to this will depend on who you ask. Some cannabis users would never dream of smoking it which is why they toss it in the trash, but that is only because they aren’t aware of exactly how much they are wasting. Vaped weed will not be as potent as the original product but will burn and can be smoked to utilize the remaining THC. It can be rolled into a joint or smoked in a bowl and will be effective with the only drawback being the taste. Since the green has already been heated the terpenes will have been damaged, so the flavor isn’t exactly sought after, but smoking vaped weed will do the trick in a pinch.

Cooking or baking with vaped weed

One of the biggest perks to using vaped weed for edibles is that the THC is already fully activated. Since the bud had already undergone decarboxylation when it was heated by the vaporizer, there is no additional cooking required, unlike recipes that utilize fresh cannabis. The filtering process needed to make the vaped weed into a cannabutter or vape coconut oil helps to weaken the burnt taste, and the results are usually a potent blend that can be added to any of your favorite recipes.

How to make vape coconut oil

Vape coconut oil is just an infused oil and is made the same way you would any cannabis infused oil.


  • 3-7 grams of vaped weed
  • 1 cup of coconut oil

  • 1 medium-sized pot
  • 1 mixing tool
  • cheesecloth
  • 1 mason jar
  • 1 elastic

  1. Add both the vaped weed and coconut oil to a medium sized pot and turn the burner to low heat.
  2. Simmer while occasionally stirring for 2 hours.
  3. Remove from heat and allow ten minutes to cool.
  4. Place one layer of cheesecloth over a mason jar and use an elastic to keep it in place.
  5. Slowly pour the mixture through the cheesecloth to filter out any plant material.
  6. Once the oil has all strained give the cheesecloth a squeeze over the jar to collect the remaining liquid it has absorbed before you throw it away.
  7. Seal the mason jar and store your vape coconut oil in a dark, cool place until you are ready to use it.
