Here's my recipe suggestion for WTA.
Ingredients
Sodium carbonate powder
25g Rolling tobacco (pref: ground)
Olive oil
Distilled water
1 x lime
Recipe
1) Sift a tsp of sodium carbonate powder into the ground tobacco and mix thoroughly
2) sprinkle in distilled water (or sodium carbonate solution) and mix thoroughly
3) when damp enough to 'crumb', leave for 30 min (it should have a pungent smell of ammonia).
4) sift in another tsp of sodium carbonate powder and mix thoroughly
5) add enough olive oil to form a paste, mash thoroughly and set for 1 hour
6) dampen cloth pouch with olive oil and place 1/2 tsp of paste into it
7) squeeze out oil in garlic press
8) repeat squeezing for all mixture (approx 10-12 squeezes)
9) place cloth pouch in garlic press and squeeze out remaining oil
10) squeeze lime juice into cup
11) place 1/5 lime juice to 4/5 oil in bottle and shake
12) repeat shakes at least 4 times over an hour or two
13) syringe off bottom layer of separated liquid and add to VG to 'taste' (approx 1:4 VG).
Liberation from ammonium salts?
Anybody have any suggestions for better ways to filter this mess?? There are some really fine particulates to remove.
What ammonium salts?
I've found that most of the fine particulates stay up in the oil layer leaving the acidic water fairly clear - so that part of the process does a lot of the filtering for you.
Possibly, ammonia has another more direct role
Ammonia potently enhances NMDA, Glutamate, and Ca2+ activity in the brain. As is common knowledge, NMDA/Glutamate is the major/most important mechanism causing addiction to opiates, nicotine, and most other addictive drugs. NMDA/glutamate activation causes the brain to hard-wire the rewarding effects of Addictive substances into the memory, thus causing an individual to strongly associate the rewarding effects with the specific drug that was consumed.
Also, not only is NMDA the major pathway causing addiction....NMDA activation is actually essential in order for Nicotine to cause Dopamine release (unlike other drugs, where NMDA/glutamate/Ca2+ activation is not essential to cause Dopamine release) .....meaning, Ammonia will directly enhance the rewarding effects of nicotine, while at the same time enhancing the brain's hard-wiring of the rewarding effects.

You mean the results that I just now finished working up?
From the 17 grams of tobacco, I would expect to get 200 mg of alkaloids using my procedure.
Seeing as I only collected half the mineral oil, I would expect up to 100 mg of alkaloids to be recovered once I morphed from tobacco/sodium carbonate/mineral oil.
My yield was exactly 100 mg, seemingly confirming that tobacco/sodium carbonate/mineral oil can indeed provide a decent extraction along the percentages of my WTA extraction.
One thing I did note about the WTA's isolated via tobacco/sodium carbonate/mineral oil, the color of the alkaloids is more a straw yellow than the copper color I'm accustomed to.
And now the vape................ That's WTA!
I mixed it to 32.2 mg/mL... I'll get a determination on the stuff in the next day or two.
Conclusion: Mineral Oil/Sodium Carbonate can pull 12 mg of alkaloids out of a gram of NAS tobacco... just like my more complicated procedure.
Wow, good news
And many thanks DVap from, I'm sure, all the regulars here for your hard work and patient, methodical approach.

I thought my patient, methodical approach drove you crazy?![]()
The most dangerous aspect of my WTA extraction is avoided in Tceight's procedure, so I think we've reached the point where I can start to tell folks how to get the WTA's produced by Tceight's procedure purified. In order to achieve purification of tobacco alkaloids, we'll have to leave the kitchen chemistry behind, and start to deal with strong acids and bases (but at fairly dilute levels). A bit of equipment will be needed as well. The single greatest hazard here will be the fact that the alkaloids will be purified and isolated prior to mixing down into e-liquid.
Stay tuned.
