I found this method on a different ecig forum and I'm sure it has been discussed here before. This entire process took about 3-4 hours to complete. You need 10mg of tobacco. I used the Zig Zag brand, about $5.00 US for 20mg. Prob. has a bunch a stuff in it besides nicotin, but I smoked anything and every thing for 31 years. Not to worried about what I inhale, obviously. I would recommend a gas stove or be very carefull and patient with an electric stove top. Get some distilled water and a measuring cup. Also filters for a drip coffee machine. Put the tobacco in a sauce pan (1 ouart). Add two cups of the distilled water. Bring this to a slow rolling boil, stirring about every 3-4 minutes. Simmer until you have about a 1/3 cup of liquid remaining. It is very important to not turn the heat up to high or you have a bunch of sticky thick useless stuff, or so I have heard. Let cool about 10 mins. I taped my coffee filter around the outside lip of a 12oz ceramic coffee cup and poured this mixture into the filter. Some of the juice seeped through, most did not. How in the heck does a Auto drip coffee pot make a pot of coffee so fast!! I finally after about an half hour untaped the filter, being carefull to not dumpt the tobacco into my juice. I folded the filter up and squeezed the remaining juice into the cup. Take the tobacco left in the filter and eat it. (just kiddin) Place the left over tobacco back into the sauce pan, add 2 cups of the Distilled water and repeat the procudere. This time slow bowl until you have a bit less juice (about a quarter cup). Remember to watch this, do not let it cook down to long or u have a thick sticky mess. Strain it again in a seperate container. Combine the two containers of liquid. Strain this again back into the sauce pan. Slow boil again until you have a quarter cup or a bit less. Strain one more time. Your done. I add a few drops of this to my favorite tobacco flavored ejuice. It seems to improve the tobacco flavor. Would gladly send a sample to some lab person for testing.

10mg tobacco ?? ;)

By far the greatest harm is from combustion products rather than pre-existent toxins. While not ideal, it is far better than going back to smoking because e-cigs just don't do it.

Early days with this. Long dabbled with by vapers, but no great pogress as yet. No teamwork; just the occasonal individual effort :(

A start would be to determine the best solvent (water, PGA, VG or some combination). Simmering may not be necessary. Also, best length of time. Would need a way to measure the nic result.

Been working on this... The exhaustive process I use for WTA is outside the ability of the non-chemist, but I'm trying out simplified procedures. One dead-end so far. Current effort looks promising.

Been there, tried this, as many others have. No known nicotine level, dirty liquid, stinky stuff, failure for me.

If you must do this, put the tobacco in tea bags for the soak. Do not boil. Just soak. But I'd advise letting dVap continue his work to extract measurable nicotine and whole tobacco alkaloids. To my mind, all you've done ruin some fine tobacco. Next, you'll ruin some fine atomizers.

I don't understand even trying this.
Nicotine juice is not that expensive once you break it down to the ml.
No one knows whats in the juice you end up with.
I think I will stick to commercially processed and filtered nic juice that is 99.25% pure.
that way I know what i am getting, and know for a fact there are not large quantities of who knows what in there.

I myself have been using PGA (95% pure grain alcohol) and a soxhlet extractor to mimic this type of extraction.
I then vacuum filter to .22um while it is still in about 250ml PGA (Started with 20gm of cigar tobacco)
I use vacuum distillation to recover most of the PGA.
I use warm bottom heat to evaporate more of the liquid. It will precipitate out some of the oils.
Re-dilute, re-filter, re-recover and re-evaporate. A lot of tars come out at the filtering step.
You end up with a very dark but low solids (low nic) juice that when mixed at 5% with VG taste more like a tobacco than anything I and many others have vaped before.
No atty damage yet after 2 months.

Have had issues with nic testing as the resultant fluid is slightly acidic (ph 5.8) So DVap's acid titration method is moot.
I need to do the math to do a .1N sodium hydroxide base titration or ask very nicely for HELP!
I'm a electrical engineer not a chemist like our dear friend DVap.
(You ROCK man)
Thank you for all your input and help.

The benefits of extracting the "whole tobacco alkaloid" provide the chemicals that are missing from most commerially available nic juice. Right now this is the holy grail that some of us seek. This missing link will make the difference between being successful at staying off of cigarettes and failure. Some of you by now may have noticed that the nic alone is just not providing a total solution.

I agree,
With both of you LOL

I have been doing my extractions more for the flavor and the trace's that ride along. But I use one of our members super pure nicotine in a VG base to fine tune the nicotine level.

I can bring my extractions down in final volume so that They are concentrated enough to add to a large amount of nic liquid.
10 to 1 is what I have been shooting for. But taste is the determining factor. Sometimes 10% is TOO much.

Not all people are able to quite smoking with changing over to e-cigs and juice exclusively. As has been mentioned (OK, thrashed to death) that nic alone may not have all the constituents needed for SOME people during the changeover from smoking.

Probably as many issues as there are people.
Different smokes for different folks. :)

Here's my kitchen-utensil method for making some DIY e-juice:

1. I mixed 6 oz (volume) of loose American Spirit Certified Organic tobacco with 3 oz boiling hot (microwaved separately) distilled water in a french coffee press.
2. Mixed everything up good with a butter knife, then poured in 8 oz NOW brand USP VG and mixed again.
3. Placed an extra paper coffee filter under the mesh on the press to filter out more particulates.
4. Placed in fridge, waited about 24 hours with the press above the mixture, cap on with aluminum foil sealing up the plunger and cap from fridge-flavor MMMM!
5. Took it out after 24 hr, let it warm up enough to thin out the viscosity, then pressed the plunger down slowly until bottomed out on the solids.
6. Re-filtered with the cleaned press again, using another coffee filter to get out more particulates.
6. Filled up a sterilized stainless liquor flask and some dropper bottles, and stored in my cool dark closet.

There's very little particulates in the liquid, and they settle in the bottles anyways. The process was not stinky at all, and didn't make a big mess in my kitchen. I accidentally breathed some steam when mixing it up, and I didn't OD or feel buzzed or sick. Got some on my hands, didn't feel a thing, and just washed it off. It's weak stuff, still good to wash up after contact.

The results:
-The taste is great, like smoking a filtered AS Organic analog, but without the smoke, mild, sweet, and vanilla/nutty tasting. Almost tastes like honey when I dropped a little on my tongue. I tried it out with some vanillin flavoring, and it works nicely together, although the vanillin makes it harsh.
-Stronger pipe tobaccos would work well with this method I think, since the flavor I got was very subtile, just like smoking the organic tobacco. I don't know of any natural or organic pipe tobacco blends out there, but they probably exist.
-It leaves some brown residue in the KR8 cartomizers, and starts to taste kinda stale after 5 refills. I gutted a dead carto, and found that it doesn't completely rinse out of the packing closest to the atomizer, possibly due to tar or particulates getting caught. Maybe the extra alkaloids carmelize on the atomizer packing that gets hottest, it didn't smell burnt, just stale and cooked.
-Mad vapor since it's VG based, it could use a little dilution to make my KR8 draw easier, but not too bad as it is right now. It makes huge clouds of tasty vapor.
-Throat hit is nice and smooth, not harsh like the PG cartomizers I've tried out recently. I actually like this stuff to refill the pre-filled PG cartos, since it mixes flavor well with the Kamel and Coffee flavors quite well, and smooths out and richens the experience. The PG cartos make me cough and burn my throat, just dripping a couple drops into the battery end makes them much more acceptable to my system.
-Nicotine, Idunno. I'm sure there's some in there, but not much since it doesn't buzz me like the 36 and 24mg cartos do, but it does satisfy the urge to smoke so I guess mission accomplished. I never got a buzz off of cigarettes once I became hooked, so I might use this stuff to accent the flavor and dilute my commercial tobacco e-juice and cartos to a level that's appropriate and to save money. I want to go to the pool store and get the chemicals to test the nicotine content eventually, but as it stands now the stuff is definitely safe. I can chain-vape this stuff and not feel sick from overdosing like I do from the commercial cartos. I do, however like the commercial cartos because they provide a quick fix when I'm busy at work (like analogs), so I won't be buying weak cartos or bringing them to work until I can step down my cravings. Inattention and red mist is no good in my line of work, gotta be sharp as a razor at all times to be safe.
-Alkaloids, toxins, tar, impurities? Idunno, I'm a race car mechanic not a chemist. This stuff definitely hits "a" spot, not "the" spot like an analog smoke, but close. This is similar to Tropical Bob's Snus tincture, I got the idea from that and used organic tobacco since I've smoked organic or all-natural cigarettes mostly, as a "reduced risk" measure.

Now I don't have to combust the crap to get the nicotine and flavor I like! [insert image of Spagett soaked in wet tobacco here, "Good News, CIGARETTE JUICE!"], damn noob rules, the picture's so funny!

Like the forum says: Do so at your own risk, this was my positive experience and yours could be completely different or poisonous. You, and only you are responsible for your own actions. This is just my way of trying something out to save money and ride out the ban if it should so happen.

I performed a similar experiment myself and have positive results. I took 1g of american spirit organic loose tobacco and put it in a small glass container with 6ml of Caol Isla 12 and 12ml of filtered water. I left it to brew, shaking whenever I was near it for roughly 2 days. I took the resulting fluid and squeezed the solids through a coffee filter. The fluid was awfully cloudy, so I doubled up a fresh coffee filter and sent the fluid through a second time and it got the particulates out. I then took the filtered fluid and evaporated it down over the electric stove top to concentrate it and get rid of some of the water and the alcohol.

I have been messing around with some mixtures from this fluid and it tastes pretty darn good... better than any commercial tobacco flavored juice I've tried yet. If a ban comes, I think I'll be ready.

Have any of you mad-scientists who've tried these various methods bothered to try measuring the nic level using DVaps pool-chemical method? I know nic isn't the main thing you're after with this, but I'm just curious how much can be extracted.

Edit: Or is the resulting liquid too dark for that method?

I have tried, but all my extracts are slightly acidic (ph 5.8) so the .1N acid titration doesn't work for me. I need to get with the program and do a .1N Base trit. test, just don't know how (yet)

His titration testing method on commercial liquids works to the "T" though.

The method I use to extract uses PGA not super-critical CO2 like the Chinese do.
They have some cheap ($20k)8-o Super-crits on eBay if anyone needs one :)
