Great question a2d.
I'd like to piggyback with this one. If asked and answered previously forgive me. I'm old.
What are the constituents in tobacco that comprise the WTA?
I promise to add this answer to my notes so I won't ask it again!
Please, keep asking! I'm hoping someone has found a comprehensive, recent study on this because I've been relying on a bunch of different studies to get some vague
sense of the major and minor alkaloids.
I'm guessing Exo or Mister or perhaps others have some answers up their sleeves as well, and this may have been covered in previous threads, but my understanding goes as follows...
Major alkaloids (percentages are in whole tobacco)
Nicotine 90%
Nornicotine 2-3%
Anatabine 2-3%
Anabasine 0.3% (
source for percentages)
Plus a whole
mess of other minor related alkaloids in small quantities, including myosmine, 2,3-bipyridyl, [beta]-nicotyrine, and others I really don't have the org. chemistry chops to comprehend.
(Some of these I've acquired from reading abstracts and I have yet to slog through the full text.)
Beta-carboline MAOIs (quantities in cigarette smoke...can't find them yet for other forms)
One source:
norharman 900-4240 ng/cigarette
harman 360-2240 ng/cigarette
Another source:
norharman + harman 207-2780 ng/cigarette total
I don't know if snus makers intentionally add additional nicotine to their portions, which would mess up the proportions when you 'dial up' the nic.
At the least, when you're going from a 'mini' to a regular or then a 'maxi' portion, you're definitely getting more tobacco, so it would make sense that you're inevitably getting more WTA...
But, perhaps some veteran snusers can report on their experience?
