I had no idea that full extract cannabis oil would be a part of my easy-to-make repertoire, but here it is! I got the recipe from a member of the Cannabis Oil Success Stories Facebook group. There are plenty of ways to do this. Here’s a video that shows another relatively simple way to make oil…still not as easy and harmless as this.
Here’s What You Need:
- Enough cannabis to loosely pack a quart jar – You can use leaf, trim, shake, sugar leaves or bud. For those of us who can legally grow, this can be a great way to use up the stuff you might normally throw away.
- A fifth of Everclear or grain alcohol – This is consumable alcohol NOT isopropyl or anything from a drug store. In Oregon, we buy it at the liquor store. A fifth is about twenty bucks.
- A quart jar with a lid
- Large Pyrex dish
How to Make Full Extract Cannabis Oil:
Pack the jar loosely with weed. It needs to have room enough for the alcohol to swirl around a bit, but it needs to have a decent amount of cannabis, too.
Pour the fifth of Everclear over the cannabis and into the jar.
You can stir it with a spoon if you like or seal the jar tightly with the lid and shake it. It is important not to go crazy with the stirring and shaking because you don’t want a bunch of leaf matter in your oil.
Next, let it sit for a few minutes – like five.
Use the cheesecloth to cover the jar opening, and pour the contents into the Pyrex dish. It will be a clear liquid in a color range from gold to bright green, depending on the weed used.
Set the dish somewhere out-of-the-way where nothing will fall in it, and let the alcohol evaporate a minimum of twenty-four hours.
Voila! It’s just that simple.
The hardest part is scraping the goo off of the Pyrex dish to eat it. I trashed my favorite paring knife scraping it, so I would suggest investing in a box cutter or single edge razor blade to get it off the plate.
The results were so surprising that I had to get some volunteer testers to confirm that it was as good as I thought it was! We found very small doses to be quite effective, even though I used leaf that I am pretty sure was headed to somebody’s trash pile.
I still need to figure out how to get it from the dish to some kind of storage. But, for now, I just scrape the plate and put about a rice grain-sized bit on a cracker or whatever, and eat it. Leaving it sitting out seems to have no effect on the potency or the nasty taste … nasty in the most wonderful way!
If anyone has trouble sourcing their grain alcohol in the US you can find it online at www.culinarysolvent.com. Ships via FedEx. 190 proof grain alcohol specifically for cannabis concentrates.
When allowing to evaporate over long period like this, what is the need if any for ventilation?
@agentsully - since it evaporates slowly, I did not find a need for any special ventilation.
You do need to dry your cannabis first. I would also suggest decarboxylating it, too - you just bake your dry cannabis at 225 degrees for 20 minutes to activate the THC.
I plan on combining the "wax" with a polypropylene glycol/vegetable glycerine mixture and using it in a vape pen.
What temp should it get to so it activates, in the vape? (Got a temperature controlled mod)
I don't mean that I will be evaporating the alcohol mixture that way.
I mean that I will be using the extract to replace the nicotine in e-liquid, and then using that mixture in my vaporizer.
What is the exact temperature that THCA will turn into THC? I am only heating an small amount, and I can watch/monitor the temperate exactly.
I normal temperature that I use my vape at is around 400F. Will that temperature be adequate for decarboxilyzation?
@minnieal28 The THCA converts at 225 degrees, hence the decarboxylization before you make the oil. I don't know anything about temps and vaporizers.
It's okay. I did some research and figured out that the flash point (temperature something vaporizes at) of THC is around 400 degrees, but CBD and CBC is 420. (Isn't that ironic!) so I'd probably vape around that temperature. I think the THCA would convert to THC at that temperature, and if it didn't, then I would get the leftovers on the next hit.
@minnieal28 I have no idea. I would not do this, myself. I just eat the oil at night.I do know that you will not want to go over 390 degrees Fahrenheit, because that is the temperature where THC evaporates out.
With isopropyl I use lots of cross ventilation, pushing air out an open window near by to reduce the fumes. I also highly recommend a silicon jar or box and a silicon tipped 'dabber'. It makes handling and dispensing the oil much easier with less waste.
Can someone tell me how to edit a post that I make on this page?
Anna Diaz, I can't access the video you refer to in your opening, Youtube says it's private. Here is a link to the best video I've even found on a simple safe way to make your own, fully decarboxylated oil, safely, in your own kitchen. In my case I substitute 99% isopropyl for the alcohol: https://www.youtube.com/watch?v=0sGWxz0DMSI
@JWilbur It looks like the original video has been removed - thanks for letting me know and for posting anther video.
I also live in Canada and I do highly recommend 99% isopropyl alcohol as the solvent of choice, it's more pure than any grain alcohol and no more or less poisonous. Either one will be carefully removed in the reduction process. If you're doing a full solvent retraction and reduction, using heat, you are achieving decarboxylation in the reduction stage.
OK, I should not have said " . . . no more or less poisonous". I meant to say, both alcohols are poisonous and both will be removed in the reduction.
@Lauradawe1 I can't recommend using isopropyl alcohol, because it is not a food grade product. I have heard of people using isopropyl alcohol to make an oil for smoking. The video in this article uses it.
My apologies for failing to mention the decarboxilyzation step in this - and every cooking process and recipe I have written for Weedist. I do this in big batches right when I get a batch of trim. So, I forget about it when I cook.
It is important to do this with any cannabis you aren't smoking or vaping, and it's easy.
Set oven at 225 degrees
Put cannabis into a 13 x 9 inch baking pan; I prefer glass. I fill it pretty full, but not overflowing, and not packed too tight.
Bake for twenty minutes. Store in glass jars and use as needed.
@medyes You're so right - It has become so automatic for me that I forget - Thanks -
Invest in silicone bakeware. You won't mess up your knives or need sharp objects to remove. Benefit, the wax comes right out!
@AmandaEnriquez Thanks for the tip! I'l sure do it!
This method provides no way of decarboxylating the cannabis. Therefore it contains no THC, only THCA. For curing cancer it is believed you need THC, so this oil is not for those trying to cure their cancers.
I believe low or no THC oil has it's uses (epilepsy for example) but I believe it will have very little in the way of psychoactive properties and will be useless in curing many conditions.
@JWilbur So sorry that I forgot to mention that I used decarboxylated cannabis.
