What Is Leftover Cannabis Pulp?

I recently received a question over in my Well With Cannabis Facebook Community from a reader who said:

“You’ve got the best cannabis cookie recipe and the easiest way to infuse coconut oil! Is there anything I can do with the leftover pulp?”

The quick answer: YES! Don’t throw out that pulp!

Leftover cannabis pulp, also called sludge, is the cannabis flower material that is leftover after making an infusion.

When making either cannabutter, cannabis-coconut oil, cannabis-olive oil, and even a cannabis tincture, there is leftover plant material from the straining process.

If you were making an oil infusion, you could simply pour hot water over the leftover pulp, let the oil and water separate and cool, and reclaim the remaining solid fat or oil and discard the water.

Or you could try one of these awesome tried and true ways to use up leftover cannabis pulp below!

Is There Anything Good Left?

Some folks argue that the spent cannabis flower is ‘garbage’ after the extraction process.

Many counter-argue that the leftover weed material is full of beneficial nutrients, compounds, and even a few terpenes and cannabinoids.

As a Holistic Cannabis Practitioner and a Registered Dietitian Nutritionist, I am inclined to value all parts of the plant, especially for a full-spectrum experience.

Chances are, there is some good stuff (ie. CBD or THC) stuck in the leftover plant material, making it worth saving and enjoying.

Anecdotally, many members of my Well With Cannabis Facebook Community, report that they find it beneficial to save the leftover pulp and use it in some way.

As long as you like the taste and enjoy it, it’s great to reuse and recycle cannabis plant byproducts wherever possible.

How to Store Leftover Cannabis Pulp

After the infusion and straining process, you will be left with a ball of plant material leftover in your filter, cheesecloth, or strainer.

If you don’t plan to use it right away, there are many different ways you can store it including refrigerate it, freeze it, or dry it out.

Just remember to keep in mind what you may want to use it for, and store accordingly!

Store in the Refrigerator

If you plan on using it within the week, you can store the leftover pulp in an airtight container in the fridge. 

Keep in mind that if you store it in the refrigerator for longer than a week, you run the chance of it molding or spoiling!

Store in the Freezer

If you want to store your leftover cannabis pulp for longer than a week, simply store it in the freezer.

Freezing does not dilute or destroy any remaining potency, and if anything, helps to retain it.

Leftover pulp can be stored in the freezer for a long time, months even.

From personal experience, I do recommend storing it in 1/4 cup or 1/2 cup portions so it’s easier to pull from the freezer and use it when you want.

If you freeze it in one big block, you will have to thaw it all out at once together too.

Just remember when thawing to never thaw it out in the microwave, as the microwave can destroy the potency of any remaining cannabinoids.

Dry to Store

If you’ve made a cannabis alcohol tincture, it is easy to leave the leftover cannabis pulp out to dry in order to evaporate off any remaining alcohol.

Simply spread the leftover pulp out on a large surface – like a lined baking sheet or large pan.

Leave uncovered and allow to air dry for a few days, stirring frequently. Feel the material to see how moist or dry it is.

Once it is completely dried, you can store it in an airtight container.

Members of my Well With Cannabis Facebook Community have reported putting this dried out material in teabags, capsules, and more.

How Much Pulp Should I Use?

If you’re brand new to cannabis edibles or making cannabis-infused recipes, it’s important to note that it can oftentimes be difficult to estimate your final product potency.

It will be even more difficult here to estimate the potency because many of the cannabinoids will have already been extracted during the cooking process.

Ultimately, the potency of your leftover weed material will depend on two things, the potency of your starting material (i.e. buds, flowers, or trim, regular vs CBD flower), and the cooking process you have already used.

For these recipes featuring cannabis pulp, it is recommended to start low and go slow.

We recommend starting with just a 1/4 cup of leftover flower pulp addition and going from there.

This will give you time to experiment with not only the potency but the taste too, as the spent cannabis flower can have a very strong taste to some individuals.
