ABV (already been vape'd) cannabis extraction techniques

Anyone have any good teks for the process?

I've used acetone, isopropyl, clean evaporating heptane, and vacuum purged the end product, but collecting a few oz's of ABV over about a year now i think its time to do something with it. I vape pretty lightly, so theres quite a bit of green still there.

My main qualms with alcohol teks, or using heptane, is they are hard to find dry as far as alcohols, and they pull a bunch of other stuff than cannabinoids, but at least with ipa its cheap, readily available in 90% dryness, and i can prob get that close to 95% with some mgso4 or naso4. Heptane is just expensive and i'd rather save it for re-x's, or use as little as possible in an abv oil extraction.

Right now, the plan is to put it in a glass, metal or hdpe tube, with a screen on the bottom and pack it in, pour the dryish iso in and let it percolate through. Then press as much alcohol out. Repeat this 3x to get a crude oily and very green/nasty tasting oil with lots of chlorophyll and other semi polar soluble crap.

Then take that, and add near boiling distilled water in a sep funnel, and "wash" away some of the polar crap pulled by the isopropyl. Warm the sep funnel in a hot water bath, and recover all the oil with a bit of dry acetone.

Then take it and dissolve in minimal heptane, and repeat the process of "water washing", but this time its more like a reverse defat, shake the heptane with cannabinoids in it and distilled water very well (might add salt to the water as well), hot water bath it to help separation, and drain off the water. Get all the heptane out of the sep funnel, and make sure theres no water, evap, and use a bung, a glass vial lowered into a vac flask with a bit of copper transformer wire, and put a good 500-600mm of mercury vac on it, let it bubble a bit and the residual heptane evap, then remove from the flask.

I might dissolve it in acetone one more time, to ensure theres no heptane still not fully evaporated, but i haven't decided yet.

Anyway, i just wanted to start a thread where cannabis vapor enthusiasts, can share their ideas and possible/theoretical teks and try to find something that gets a decent end product.

Feel free to share your extraction methods, comment/suggest changes to mine, or contribute in any way in regards to extraction of already been vaporized cannabis.

I just can't make myself throw it away, and end up with tons of the stuff, knowing theres at least a few grams of good oil in it. Not tasty, but definitely sedating and stony. Worth extracting imho.

And as always, do evap tests on your solvents, and vac purge your oil if you can to vaporize off volatile residual solvent traces. Especially when using something like heptane.
 
Yeah, lol, its prob one of the best ways to go about it.

I was the kid that had to learn the hard way why you have to be extra careful playing around with pressurized extremely flammable gasses in enclosed containers, so theres a bit of bias and aversion to that method for me. Spending damn near your whole summer with ace bandages, and 2nd degree burns on your arms and legs, makes me hesitant about playing around with butane extractions :lol:, but i don't think it can't be done safely, its just not my cup of tea.

I'd substitute supercritical co2 gas for butane though, if it was as simple of a process as butane extractions. Even then though, thermal stress and high pressure, won't touch that with a ten foot pole unless i'm confident i won't end up with shrapnel scars. And that means hundred/thousand dollar equipment in regards to co2 from what i understand.
 
Add 1-2gs to a pint of milk, boil for ~30 mins, add cocoa, honey, maybe a little ginger, nutmeg, cinnamon or chilli, serve and enjoy :want:
 
not trying to be a negative nancy but ive been around marijuana my entire life my father was in the industry his whole life abv pot will not make anyting that great ive seen everything tried from hashing it cooking with it making extractions weather solvent based or not even seen friends try to do inverted stb with it just have never really seen it work too well. honestly best thing i have seen is save it all up roll giant hooters or cook with ALOT of it
 
idk bonger, sounds like he got good results with it.

what could cooking do that couldn't be achieved with extracting?
why would smoking vaped bud be more potent than smoking its extract?

also how can you invert an STB (basing after pulling would make no sense)?

it seems to me more a question of your friends extraction techniques/solvent choices than anything else.
 
ok dude whatever you think the stb was one solvent method. abv is not worth your money in solvents cooking it cost like 5 dollars instead of risk of scoring butane which is considered precursor chemical in many states and costs much more. vaped weed isnt worth the money or risk to extract from thats multiple felonies for low gain when you buy butane and drive with it and get pulled over your scrwed. smoking a giant j is gonna get you stoned and isnt a felony if you wanna extract go spend a little extra money buy so low grade mexi and go to town other wise abv is better to cook or smoke. most people i know throw it away.

isopropyl costs $2...
also if butane is illegal where you live, don't use it as a solvent?
seems to be common sense (also what do you use for refillable lighters in places where butane is illegal?)
i am not trying to come off as abrasive, it just seems like you may be dismissing this method a little bit too readily.

but seriously, what is an inverted STB? my curiousity is piqued.
 
Bonger couldn't be wronger. :)

I use naptha or heptane. A couple 30-45 second pulls, filter through coffee filter, evaporate solvent. Heat purge. Let it cure for a few days. Smoke.
I find that the oil from AVB is great for sleep. It has different qualities that oil made from fresh bud. It sure works though. I don't think you should expect to get the same thing from AVB that you get from fresh. I imagine the heat changes quite a bit.

Maybe Bonger is vaping too hot and trying to extract from something that's mostly carbon.

That pretty much fits my expirence, abv is way more stoney than fresh bud. I might just be thinking too hard about this, heptane hash, with a good vac purge might be my best bet here.

what is your technique for doing this?

i ended up taking a flame and raking along the top of the extract, gets the job done, but i can't help thinking there is a better way.

i tried a hot water bath and it didn't seem to do much (which kinda makes sense because i used a hot water bath to evap)
 
hahaha ok still extracting buying any kind of butane or solvent can be called precursor chems so much risk so little reward and its true even if you got a 7grams of product is that worth all the felonies you just commited???



most of us already have other extraction/sketchy things in our homes scales/pipes/dirty jars/ anything police call pariphanelia. Also go ahead and use unrefined butane lighter fluid for a refiliable lighter lol you have to used refined butane or your going to die so when you buy refined butane 1 can or 10cases you can go to jail and under certain circumstances anything can be called precursor chems even isopropyl

all im doing is pointing out massive risks for such little gain you already enjoyed that grass once why take all the risk to enjoy a little bit more
 
alright guys, you heard him.
don't buy butane or isopropyl or you will go to jail 😁

getting what you need to extract DMT is totally fine, however :roll:.

because butane and iso are sold commonly at grocery stores here..

i haven't been arrested yet :d
 
cmon dudes, lets keep it civil. I already ruled out iso/butane for quality/saftey issues. And saying butane/iso are watched is compeletly paranoid. Granted, go buy a barrel of technical grade ispropyl, and have the cops come to your house you better have a good reason for having it, or having way more butane than any civil person would need for lighter-refills is a bit sketchy, but thats not what were talking about.

And i don't like butane/heptane extranctions anyway, since they use alot of solvent, and release the volatile gas forms of said solvents into the atmosphere more than whats necessary, unless your recycling them via distillation, and with cannabis terpenes, i don't think it would be posssible to do so without contamination of the distilled solvent.

I think my best bet at this point, is a good water cure, a qwiso pull, evaporate that, and then a heptane extraction using minimal solvent, to leave behind the polar nasties brought over with the alcohol, but insoluble in the heptane.

You're probably not going to like this, but I swear that it works with no perceived loss in potency. It makes the oil darker, but it also makes it easier to work with.
I put it in a small microwave safe dish. Add a couple of drops of water on the top of the oil (amount of water would vary, depending on amount of oil. Microwave for 15 seconds, stir, repeat 4 times. The oil will bubble up. I'm assuming this is the residual naptha and that it escapes when I stir in between heating. After I'm done microwaving, I put the oil in the freezer for a few minutes. This seems to harden it further after it thaws. Don't know why.
The resulting oil has no naptha taste and bubbles up with gently applied flame, without catching on fire.
 
day tripper seems to see what i mean on more than just legal safety but also on eco safety however others still seem immune one day shit hits the fan it does for everyone people are pointing things out to you take them with a grain of salt rather than argue them. and no i never said it is ok to get the extraction materials for dmt thats the point im trying to make. butane/iso from a store is NOT good for you please for your own safety dont use that it isnt not refined at all unless you live in some states where they sell 99% iso suprisingly i have seen it in hydro stores

oh and iso butane is watched especially in states with medical marijuana because concentrate is still felony. any state with a large marijuana economy has its eyes on butane trust me

that does seem a better method than burning all the excess flammable solvent off with a lighter.

i have noticed that butane makes the hash oil a tannish color, and removing it leaves the oil much darker than before it was contaminated (a blackish-red). so i don't think anything much is happening to the oil itself (especially if it still produces non-flammable bubbles when exposed to heat - in fact you may be cooking it even less than i do with my bic)

thanks for the tip.

that is not true actually, iso is just water and iso (regardless of percent, and if you want to use 70%, just dehydrate some epsom salts, add that to your iso, and it will absorb the water leaving behind mostly pure iso). i checked the msds on the butane sold in stores near me (there were two kinds - both were pure) and they were fine - just do a little research beforehand.

talked to all my friends and family in CA who use butane regularly. none of them have been arrested either.

it almost seems like you can go to the store, buy moderate amounts of a substance sold legally, and then go about your life. but don't be fooled, that is just what i want you to think.

i am sure if you bought inordinate amounts of butane or any solvent, it could possibly lead to this kind of circumstance. but just buying a small amount (say 3 cans of butane, or 1 bottle of iso) will probably not lead to your arrest.
