TB, thanks for the info, I think I was tending in that direction,
was thinking work up to the 'mans' snus via the more pleasant ones,
rather then getting disgusted & walking away from it,
but having got these 'WTA packets' I've probably got to go thru the
same horror & joy experience with snus you've obviously been thru
Sorry about not coming over to the 'snus side' Stubby,
probably see you on the shortly....I hope.
DVap, I can see why your original sig. said 'Never annoy a chemist'

,
gotta say I feel 40/60, cos if a simple soak can somehow get a higher
alkaloid content than you've seen (a physical process? - e.g. less liquid per
tobacco, heat,
microwave, much longer soak, sonicate, squeeze it - ?),
and a substantial degunk can be done, (filter, acidify, alkalize, a precipitate?, settle/filter?)
maybe there's still a chance...
But on the whole it's never going to even approach your WTA+, in terms of
cleanliness / vapability / strength.
However, did I get the feeling you were trying water/ether rather than MeCl2 extraction?,
if so does it work anywhere near as well (or at all usably)?
Can people get ether easily, is it 'safer' ?
TV : never come between a practical chemist & a knowledge-researcher

don't think saliva actually contain any enzymes except amylase (carbohydrate attacking enzyme),
not sure how that would help alkaloid extraction/migration, but you never know....
DVap just described snus as pre-packaged WTA, is implication is that the snus pre-process
does pre-extract the alkaloids c.f. loose
tobacco, so they're more quickly available,
or it it just the snus usage time-frame (in the mouth) is vastly longer
and more alkaloid conducive (somehow) ?
