I got some of these in the mail the other day as well as some Starr scotch. Was not impressed with the Starr too plain for me though definitely easy to snuff just blah tasting. Re hydrated a tonka bean and threw it in some Starr and now I can’t keep my nose out of it. Such an interesting aroma these things have and such a nice flavor it gives to a plain snuff.

Way to go man!

I heard they are vanilla-like?

Is it safe to use a snuff containing cumarin regularily?

From what I have read unless you are a rat tonka beans are safe. Especially in the amount I used I just soaked it and put in a snuff box with snuff. I did not actually grind it in so the scent is very subtle.

I doubt if any coumarin is absorbed since the snuff is only capturing the odor of the beans and no part of the bean is actually ingested.
