One of the most frequently received questions from the members of our VapeFuse Community:
‘So what should I do with the leftover? Can I reheat it and use it over and over again? Or just throw it away?’
Well, we all want to get the maximum benefits out of our herbs without any waste. Because we want to make sure every single vaping session is a remarkable one, great taste, great quality vapor, great time, happy face, and of course, we are very conscious of our money as well.
The shift from combustion to vaporization in the consumption of dry herbs gives users a health-friendly solution to get the best medicinal benefits out of their dry herb blends.
A cool thing about vaping and vaporizers, as opposed to smoking and combustion, is that vaping the herbs allows you to utilise the already vaped material. For example, the consumers of medicinal cannabis, in countries where marijuana consumption is legal, tend to reprocess the vaped leftovers and use it to create rich cannabutter or cannabis chocolate.
Even if the vast proportion of the active constituents get extracted from the herb in the first round, already vaporized herbs can still be used as an ingredient for instance for brownies and all kind of treats.
Since I’m big on baking I gotta tell you my new favourite is the Peppermint biscuit. I’m sure many of you love Mint Chocolate, well here we are… I’m a regular Peppermint vaper, it gets me focused and I love the taste and smell of it. After each session, I just put the residue aside after emptying the chamber and use it as an ingredient for my weekend sweet treat.
But let’s learn a bit more about the medicinal value left and the re-use of the fully vaped herbs.
The Medicinal Value of The Dry Herb After Vaporization
Wondering if you can still reheat and reuse your vaporized dry herbs? Well, yes and no.
After vaping your dry herbs, the leftover has been activated due to heating and only retain low concentrations of extractable, active ingredients. They can make delightful, but not highly intense byproducts.
For instance, after medical cannabis undergoes vaporization, it still contains therapeutic cannabinoids.
The level of cannabinoids retained in already vaped buds varies by temperature used to vaporize them in the first round. Exceedingly high temperatures yield amorphous and crispy chunks unsuitable for reprocessing.
Lower temperatures ranging from 175°C to 190°C (350°F to 375°F) give maximum potency and still hold considerable amounts of cannabinoids you can reuse.
When you vaporize medicinal cannabis, heat stimulates the acid form of cannabinoids, such as CBDa and THCa into CBD and THC.
Unlike combustion, vaporization only activates the ingredients but does not denature proteins, so that all the original properties do not get exterminated or diminished.
Vaporized cannabis may still hold up to 20% to 30% of the cannabinoids compared to before vaporization. As mentioned above, enthusiasts don’t mind using the ‘leftover’ as an active ingredient for a variety of cannabinoid infused edibles.
Reusing Vaporized Dry Herbs – Does Temperature Matter?
After fully vaporizing your favourite dry herb, you cannot get the original extraction of active constituents out from your residue, as they have already been exhausted due to sponging off all active ingredients at high temperature.
If you set your dry herb vaporizer at 160°C (320°F), it’s more likely there will still remain some medicinal value in the vaped herb, than using your vaporizer at the temp of 230°C (446°F), since the residue at a lower temperature will preserve more ingredients that you can beneficially further reuse.
Let’s get back to this ‘greenie’ herb for a moment, since this topic is pretty big these days due to the spread of legalisation of medical cannabis all around the world.
Studies have discovered that the perfect hit for vaporized medical cannabis checks in at 170°C (338°F). However, the cannabinoids begin to evaporate at a lower temperature, from 140.5°C (285°F). When vaporized, most cannabinoids get dissipated together with the unique taste, smell and impacts.
Vaporized cannabis first expels terpenoids that have a lower boiling point of 55.5°C (132°F). Typically, users seeking a pleasurable, aromatic spot start with low temperature and inch upwards to polish off the material.
Vapes with Preset and Adjustable Temperature
Alright, so we keep talking about the boiling points and different temperatures used to vape your precious herb, and you may wonder ‘how can I control the temperature?’, ‘is it something that all vaporizer can do?’
Here you go, luckily, you can fine-tune temperatures if you have a vaporizer with an adjustable temperature control.
Most desktop vaporizers out there come with digital display and the temperature can be set by the user. I won’t go into a whole lot of details on this, you can find out more about preset or adjustable temperature vaporizers here.
A lot to think about when you are about to get a vape, right? Check out our FREE Vaping Guide, it will surely help you to find the best vape suitable to your needs.
The Taste and Potential Downside of Reusing the Leftover Vaporized Herbs
Despite the popularity of dry herb vaporizer leftover used in edibles, there are always some people who just cannot get around its taste.
Depending on the treats you make, you may find the product tasting funny due to its bitter, burnt, popcornish taste and smell.
If you are one of those whose taste buds are a bit picky, well, then just deal with it 🙂
To avoid any issues, you must watch for bacteria and other disease-causing microorganisms. Keep the vaporizer leftovers in a cool, dry place such as a refrigerator.
Let’s Sum Up What We Learnt Today
When you finish drawing in on your vaped dry herbs, you can always stash up the leftovers for reuse. Depending on the type of dry herb, temperature level, and how fine you grind your herbs, you can tap into the vaporizer residue.
Refilling your chamber with already fully vaped herbs is not highly recommended since most likely the medicinal values have gone after heating the dry herbs to your preferred temperature.
But nothing to worry about, the variety of recipes of using the vaporized dry herb leftover is endless, give it a try and sure you won’t regret it.
