Just to collate general methods for flavor extraction from tobacco in this new subgroup, I am pasting in my original post of my method. It is unlikely that this VG extraction will obtain significant quantities of nic...this is a flavor recipe, not an e-juice recipe. Since it is a flavor-only extraction method, this recipe is not exact in amounts, but in the future I will post exact amounts and outcomes. That is when I use up or get tired of the essence I have made...and this stuff lasts a long time.

My original post for Pipe tobacco Essence:

I should say up front I am in general not a fan of tobacco flavored juices. Tried several and didn't like any of them much. This pipe tobacco essence is to me delicious and very useful as a flavor on its own and with other flavors.

What you need:

A 10-12 mL syringe
A cotton ball
A small sauce pan
A stove, preferably gas for better heat control
VG, about 30 mL
Pipe tobacco...I used Stanwell Melange for one and a bulk cherry tobacco for another. Two heaping table spoons is about what I used, but I didn't really measure closely.
Dropper bottles

Put the VG in the pan, and bring it to just boiling with some visible bubbles rising. Remove from the heat and add the tobacco, swirling it around to soak all of it. Put it back on very low heat and bring it slowly back up to just simmering (a couple bubbles but not lots of boiling). Let it simmer for 30 seconds, then remove from heat, cover, and let it sit overnight.

The mix will be very dark the next day. Heat it up a bit to get it flowing, then decant the liquid into the syringe with the cotton ball shoved down into the bottom. The cotton will act as a filter. The liquid will look like dark honey. Fill the syringe and put the plunger in, and press the liquid through the cotton into a dropper bottle. You can press liquid out of the tobacco in the pan, so it flows to one side, then decant this into the syringe as well, and press it through the cotton into the dropper bottle. 30 mL of VG made for me about 20 mL of liquid, with the rest held by the tobacco, which did not press out. I avoided really squeezing the liquid out to minimize any vegetable matter in the liquid.

This liquid is likely very low in nic or the other alkaloids, but it is huge with flavor. This liquid, which I call pipe tobacco essense, is a VG-based flavoring now. I like it at about 30% in a juice I make with unflavored nic juice and distilled water to thin, but my favorite way to have this essence is to put a few drops in my cart, then a few drops of a high-nic juice I make with Capella Caramel, then a few drops of essence and a few drops of the caramel juice. This is easily the most satisfying juice I make, even without nic. One could vape it straight, which is really excellent, but it is thick and best thinned a bit. I dedicate an atty/cart for it as I have found tobacco juices do require more atty-cleaning than most other juices, and the flavor is quite rich.

I've had others try it that are familiar with my mixes, and everyone says this is the best one I've made. I find it really relaxing and so very very satisfying that I am wondering if the hot VG is actually getting the alkaloids out. The chemistry says I shouldn't be, but no juice I make makes me forget to smoke as well as this one. Perhaps the deep sweet tobacco flavor is creating an effective illusion. Regardless, I absolutely adore this essence.

YMMV with relative amounts of VG and tobacco, but both are cheap, and its really hard to go wrong with this. I have not experimented much with relative amounts or cook-time...my first batch was so good with this recipe that I've just been vaping it, and a little goes a very long way.

Hope other DIYers try this and love it too!

Update: The PTE I made a few weeks ago is still stable at room temp. There is no sign of mold or bug growth. The flavor has deepened. When making e-juices from this, I simply use it as though it is pure VG, and make the juice with unflavored VG nic juice and about 20% distilled water. Think of it as making an unflavored VG nic juice from high-nic VG nic, but in stead of diluting with VG, you use PTE. It is so good!!

Another thing I do with PTE is this: in my 510 cart, which uses AquaClear foam as a filler, I add a couple drops of straight PTE to the cart, then a couple drops of another "normal" e-juice, like a caramel juice, then a couple drops of PTE, then the other juice, etc, until it is filled. This will thin the very thick PTE, and bring in another flavor that goes well of the particular pipe tobacco flavor. For the Stanwell Melange PTE I made several flavors meld well with it: caramel, maple, fruits (PA blueberry is great).

I think thinning it with a little vodka or PGA would be excellent for many here...it would open the PTE flavors even more, no doubt. I do not vape alcohols for several personal reasons, but many do, and this would I think enhance the flavors a lot.

Warning: like other tobacco juices, PTE can make your atty sluggish, like from particulates that are very hard to filter out completely. I suggest dedicating an atty to it, and clean the atty every few days if this is the case for you.

If you consider that my Doral ultra lights (before they took the nic and tar values off the pack) read 1mg tar and 0.1 nicotine per cig, The values for pipe tobacco sound about right. Pipe tobaccos have a lot of flavors and additives that make them feel thick and tarry.

A tablespoon might be about right for rolling one cig, so you are talking about 2 cigs at .5mg to .75mg nic if you had rolled it. That's sky high compared to my puny Doral at .01mg. I would expect pipe tobacco to knock my head off unfiltered or filtered.

In order to obtain a cleaner vaping PTE, this might be of help: Soxhlet extractor - Wikipedia, the free encyclopedia. An Isomerizer, manufactured in the 80's might do the trick as well. Use of either by a married vaper will likely have said vaper's spouse feeling this new hobby has gone too far:D

Rolygate said:
DVap, why is the nicotine content likely to be so low?

I guess I could answer that myself: this quantity of tobacco is equivalent to one cigarette or so, and there isn't much nic in one cig.

RG,

It's just the mass/volume relationship at work.

I've found that cigarette tobacco (NAS, for example) contains about 2% alkaloids. That sets your upper limit. If you have 5 grams of tobacco, you're looking at 5 * 0.02 or 0.1 grams of alkaloids (mostly nicotine).

Since 0.1g = 100 mg, your going to be extracting that to a certain volume, in Kurt's case, he was using 30 mL. So that sets an upper limit of 100 mg/30 mL or 3.33 mg/mL in alkaloids/nicotine.

I fudged it down to 30 - 50% of the 3.33 mg/mL since it's probably a stretch to assume that the PG extracts the tobacco all that efficiently... thus my 1 - 1.5 mg/mL figure.

In the threads where I discuss the high power alkaloid liquid I've made and knocked Tropical Bob's and a few others' heads off with, I overcame the limitations by using a much more sophisticated extraction and cleanup... such that I was able to extract a lot of alkaloids from a lot of tobacco, clean it up, and then isolate the alkaloids into an organic solvent that's then evaporated.

Just to reiterate, PTE is by and large a flavoring. As DVap says, even if the hot VG got all the nic out of that which I used, and then essentially diluted to 30 mL volume, the nic content would be quite low. That said, I do not have info on the ability of the method to extract the other alkaloids. Perhaps it does get some, and perhaps, unlike nicotine, very little of the other alkaloids are needed to increase the satisfaction of the vape. I do not know if these two things are actually true, but I was quite amazed at how well about 12 mg juice that I made with this PTE flavoring satisfied me. It did a better job than if I vaped another juice with different flavoring and higher nic content. Perhaps it is a placebo effect from tasting tobacco, but it seemed to be more real than that.

The one downside of PTE is its tendency for me to clog my 510 attys on my 3.7V box mod. I've noticed this with every tobacco-type juice I have vaped for extended periods. I believe this is due to either particulates or maybe tobacco compounds that caramelize some on the mesh. Perhaps just more filtering is needed. Right now I tend to just add a couple drops of PTE to a cart that has another compatible nic-juice in it. The Stanwell Melange PTE I made marries well with fruits, caramels, vanillas, and adds a deep richness that is just delicious.

Ok the results:
At 20% it is smooth! Nice vanilla tobbaco flavor. Here is a pic of the collected extract, I was able to collect roughly 50% of the VG 88.5ml. Pic attached:

Right, so the tobacco extracts we are making, via the simple route of just boiling tobacco in VG, are likely to be very low in nicotine.

I wonder how this compares with Tobacco Absolut (the extract you can get from eg Perfumers Apprentice)?

This is a thick black goop that is prepared from Tobacco Concrete, a solid that results from the full extraction of all extractable materials from tobacco leaf on a commercial scale by using something like hexane or benzene then evaporating the solvent. No doubt TA has a fair strength of nic in it.

No doubt TA has a fair strength of nic in it.

Actually, the TA's I've seen have been stripped of alkaloids... not sure the method. I've looked up all the references I could find, and one mentioned that there's no reason a TA can't have the nicotine/alkaloids present, but I suspect that with TA generally being sold as a fragrance component, this market would consider nicotine/alkaloids as undesirable.

Trouble is, even if a TA was identified that keeps the nicotine intact, the stuff is SOOOOO strong, that by the time it's diluted to a bearable level, it's extremely diluted.

I got my hands on 1 mL of tobacco absolute from a supplier (I sent him 200 mL of 95% PGA, he lives in one of THOSE states where you can't get it.. so he sent me some TA in return).

I ended up diluting the 1 mL of TA in 20 mL of 95% PGA, and generally 2 or 3 drops of that will do for 20 mL of eliquid. So we're looking at 0.15 mL out of 20 mL (about 7.5 mg of TA) and that 7.5 mg gets diluted to 20 mL in eliquid.. so the TA is at 0.38 mg/mL.

I recall that when I opened the 1 mL TA vial, it was instant tobacco shoppe. The odor was strong, persistent, and quite pleasant really.
 
Good to see this topic hasn't been banned.

In the little trials I did many months ago I was quite pleased with the results, low nic or not, and it is probably the presence of 'others' that makes it so (and that includes flavors, which after all most of us have long associated with the physiological effects, and which undoubtedly are nicer sans most of the tar and all the ash).

@Kinabaloo,
This topic won't be restricted because there appears to be little risk involved. I think we have established that neither TE nor TA contains any significant amount of nicotine, even in its first-stage base form. It might have unpleasant effects if you drank it but it would probably only be around in small quantities, and it would be like trying to drink nitric acid mixed with tar. Difficult. And standard eliquid would be more toxic.

@Lexi
No idea why you got a bad result. Either the VG or the tobacco were perhaps wrong for this job.

On the other hand, it needs diluting a lot more than 50%. Also, alcohol seems to help, a 10% solution diluted down with 50-50 VG and alcohol seems to work well. It could be like menthol for example, a strong solution is disgusting, but diluted to a very weak end result and it's very pleasant. Too strong and it is vile. The alcohol also seems to help it disperse in the base liquid it is added to.

The trick with TA as I've experienced it is to get the right amount of TA dissolved in alcohol. I've been fairly pleased with 1 ml of TA dissolved to 20 mL in alcohol, then adding this drop-wise to the eliquid until the result is satisfactory. Best to experiment with lower volumes of eliquid in case you overdo it. Once you're happy, you can always scale up.

It's hard to say exactly how much is proper, a clear case of YMMV. :)

I had hoped the reasoning was more enlightened.

DIY tobacco extration could be dangerous, but that's no reason not to discuss it; especially as some people are sure do try it - better to be informed of likely concentrations etc. Might not be as dangerous as e-liquid, but still wise to avoid any skin contact. Depending on the amount of liquid employed (and other factors) the nic content could be significant - and that (plus other alkaloids and flavors) is why it is of interest.

A carefully titrated determination of the result with a minimal liquid amount (highest concentration) would give a sound baseline for the discussion; though even theoreically - with considered estimates - suggests that DIY extraction could provide more than 'negligible' concentrations; and hence be useful beyond mere flavoring. AFAIK, that's not yet been done.

BTW: Extractions or e-liquids should absolutely never be drunk or tasted, no matter how diluted - mentions of that by others were definitely a joking!

Kin. - I had hoped the reasoning was more enlightened.

You want enlightened? Sorry to disappoint you but we are all just tired, bitter, reactionary old hacks here. Well I am anyway.

It would be very interesting to titrate TE for nic strength, but I'm given to understand that the colour change signal is blue to yellow. As the liquid is likely to be dark yellow even when extremely diluted, this might be problematic?

I'm looking for a 2nd-hand Soxhlet extractor I think, any ideas? :p
