THC glycerin extract or "THC drops"

[Spence_tron]

So does anyone still remember that BLTC thread on &T right before it shut down about "THC drops"? Well the guy claimed that if you steep bud/trim in vegetable glycerin for 2 months and then filter it you would have an ultra-potent sublingually administered cannabis extract active at as little as 1-3 drops. He claimed that it was a great way to extend a weed supply, saying that he got hundreds of doses from an ounce of bud with this method.

I had a hard time believing his claims but the topic recently caught my interest when I found some veg glycerin locally at the brewshop. I did some research on the topic and found that there is some legitimacy to the method from &T. But I found some problems using glycerine over alcohol for these kinds of extracts. First, glycerin is much thicker and a less aggressive solvent than alcohol so extraction time is long (2 months long apparently). Secondly, glycerin extracts don't keep as long as alcohol extracts and go bad eventually. Glycerin also only extracts ~70% of what alcohol extracts do per ml. But glycerin extracts absorb sublingually while alcohol extracts don't... which may explain the reported extreme potency of "THC drops" since sublingual administration is nearly instantaneous and rather efficient.

So I tried my hand at this extraction method with a little twist to combat some of the problems I read about. I started off decarboxylating about an ounce of bud/trim in the oven at 170F for a half hour and added it to 4oz of food grade vegetable glycerin. I threw in 3-4 grams of pressed hash too, just to make the extract as potent as possible (aiming for 1-3 drop doses).

But to make the glycerin less viscous, speeding up extraction time and increasing filtering efficiency, I added 1oz of 190proof everclear (which should also make it pull more cannabinoids and help it keep longer). I read that combining ethyl alcohol and veg glycerin produces propylene glycol (which is also a suitable solvent for THC drops) from a few sources but I'm not sure how true that is. Either way an everclear/glycerin mix supposedly works good for this purpose too, from what I read.

The bud/trim/hash has been steeping for a month now and I'm almost ready to filter, I'm still wondering if I should wait the full 2 months or not since the everclear made the mix so much less viscous.

Did anyone here ever try that tek from &T? Does anyone have any experience with this?

Bump for intrest

I honestly don't think that two months of extraction will get anything that a full month wont. That's a long fucking time... Regardless, you could leave it on and take a small amount of liquid out and test it for potency -- nothing wrong with that. Give it a try and report back.

[Spence_tron]

^ You know, that's an excellent idea. I'll pull some out with a filtered syringe, test it later this week, and report back. I can't believe that didn't cross my mind.

I've admittedly always messed up my observations with weed edibles because I always grew impatient waiting for it to kick in (1-2hrs) and smoked in the mean time... throwing off any initial comeup observations. BUT with sublingual administration, it should in theory kick in within 2-5 minutes. And I'll try my best to not skew the results this time... for science!

[I Kill Null Airtime]

I remember that thread!

[meateor]

Yeah buddy!

Seriously, if this works I'm gonna be the happiest girl in the world.

Edit: Also, could you vape this mixture/put it in an e-cig catridge and get super outrageously baked?

Edit2: http://forum.grasscity.com/seasoned-...confirmed.html

I googled THC drops and this thread came up. A bit of information, a but of lulz. enjoy.

Also, &T can't be trusted. Period. lololol

You could try gently heating your mix in a water bath to ensure maximum pull before filtering

[DeepWithinMyMind]

I don't know about glycerin, but one of the caregivers i know makes a marijuanna tincture for sublingual administration using everclear and it works wonderfully. Though the potency is entirely dependent upon the amount of plant matter you put in and it takes alot to get any sort of potency.

If the absorption rate of THC into glycerin and alcohol is similar then 2 months is way too long, unless doing multiple soaks. 2 months will probably pull more chlorophyll than anything.

Interesting, post back with results.

As others have said I wouldn't wait 2 months, fuck that, 2 weeks is good enough. Also my friend made tincture and it def won't kick in as fast as 5 min. I would take it sublingually the best I could, a squirt of it, and maybe 20 min. later I would feel it at the earliest. It's sort of subtle and nice, definitely smoke with it you'll notice the something extra.

Not sure how absorption through the membrane in your mouth is going to be more efficient than hundreds of feet of intestine. If you want stronger doses make really strong cannabutter, it should not be taking 1 - 2 hours for your edibles to kick in. You should be feeling the effect in 30 minutes and the full effect around an hour. Do you make all your edibles, and why are you so interested in having drops? Are you unsatisfied with a tincture? 1 oz., a shot of tincture should be enough for anyone.

I guess you wouldn't wait 60 years for your barrelled whiskey either huh?

Hey OP my name was Frackle back then... So...

Your welcome.

[Edit]
Didn't read the full post.. Still haven't.

The drops go under your tongue and you hold them there, It gives you a body buzz for the most part and numbs you and your pain. I used to make it for people with CPS or other problems but I've since gotten out of it for my own reasons.

Usually what you want to do is cut down or grind your weed and place it in the bottom of a mason jar to the 1/4 - 1/3 mark then fill the rest with food grade vegetable glycerin and leave it on a windowsill for 2 - 3 months turning it upside down and right side up so it evenly mixes itself.

You should be left with a dark green liquid which should be your THC drops.

As a bonus I used to cut the use of the glycerine in my drops by adding in some high grade alcohol (preferably vodka) and my drops turned out alright for ingesting.

If you poke around a bit you might find a thread started by me for pHot Sauce... It uses THC drops and home made hot sauce to make a delicious treat of deliciousness... If I arse myself into it later I'll dig it up.

Edibles just take a long time to kick in for me for some reason. My friends will eat the same edibles and come up quicker, it's just me. I make most of my edibles (usually cookies, brownies, or coconut oil pills) but I've had other peoples brownies, cookies, and BHO lollipops before. They are always plenty strong, it just takes over an hour for me to come up for whatever reason.

I've been interested in sublingual administration of cannabis tinctures for a while, but an everclear tincture would leave your mouth raw (I also read that glycerin is better for sublingual absorption). And alcohol pulls a lot more chlorophyll and nasty flavors than glycerin does. Sublingual administration apparently has a different effect than both eating and smoking, so why not explore it?


1983: You were the original author? Well, thanks for sparking my interest in that case. The whole mix has been in a mason jar on the windowsill, wrapped in a paper bag to protect it from UV. It has taken on a deep amber color with a green tinge. And like I mentioned in the OP, the glycerin is cut with 20% 190proof alcohol for a few different reasons. I think what I'm doing here is quite similar to what you had been doing, I hope for similar results.

Just arsed myself.

Sorry for not updating sooner guys, I've been working a lot.

I tested out the drops on a camping trip, being sure not to smoke before the drive there so I could test it sober before we all started smoking/drinking once we got there. I started off with 3 drops, the taste was sweet and was only mildly weedy in flavor. I could feel *something* within 10-15 minutes but realized I needed to take more. I found the correct dose to be more around .5-.75ml (~8-11 drops) for me. The effects were more akin to oral ingestion than smoking, but noticeably more 'heady' than edibles. It reminded me of the difference between vaping and smoking weed IMO. The high lasted only 2.5-3.5 hours, much shorter than edibles last for me (around 6hrs) but redosing was easy and effective. The high was clean and kept me active/aware unlike most edibles which make me lethargic. Throughout that camping weekend I tested the drops while smoking, drinking, on edibles (hash cookies) and on acid. It potentiated the edibles and blunts very well, and certainly improved my acid trip. I even had a chance to test out some of its medicinal value... I got a real painful charley horse muscle cramp in my calf while trying to get out of the river in some difficult rapids, I took 6 drops of the tincture and my leg felt much better in minutes. It also helped with a headache I got from shooting a gun at a few lbs of tannerite standing way too close, the detonation left me a little rattled to say the least (warning/reminder to be safe when or if mixing firearms/explosives and psychedelics/alcohol!).

All in all I'm pretty impressed with this glycerin tincture, I can see its advantages over other methods of extraction/administration. But I do aim to make a more potent extract and plan on adding a little more hash to the main jar still sitting on the windowsill to bump it up a few notches. Either way, I'd still call it a success. It definitely improved my camping trip and I'm looking forward to testing it out further once I filter the rest of it.

Cool, would you say it's more efficient than other edible methods? The hardest thing for me to believe is that it would last you considerably longer per oz.

[ChinaCat]

Dont charlie horses go away in a few minutes anyway?

But yeah i also dont feel edibles for at least an hour, and then always eat more and get
More zonked than i want to

I scored some tinctures and thc capsules recently and prefer it to edibles myself, glad you made this thread cause this is what im gonna start doing

[1983]

Did you take the drops under your tongue and hold them there?

Lots of veins under your tongue and it help the THC drops move into your circulatory system.

[Spence_tron]

ChinaCat: Yeah, they usually do. But I fucked it up worse trying to get out of the rapids after it happened so there was a lingering pain for the remainder of the trip.

And Gun Lover: I would say it is more efficient than other methods, seeing as it took me only 3x much as was proposed in the old totse thread (which was stated to be so efficient it raised doubts). It could be that sublingual administration (using glycerin based tincture at least...) does actually have superior absorption. I do want to test it out more before affirming that statement though.


BTW, does anyone think that this tincture/administration could benefit from CYP-450 inhibition like edibles do?

Edit: Yep, I held them under my tongue for as long as possible, 4-6mins I'd say.
