No, I'm not going to advocate the use of tobacco here, but since I'm unfortunately an addict to nicotine, I really wish I could get addicted to snuff instead of cigarettes; it's definitely classier and not by far as lethal (but not good for your nose. Tobacco is bad - period!).
And you get to have a snuff box - ha! Of course you can have a snuff box without actually using snuff. Why not fill it with breath fresheners or sweets (tiny, tiny sweets)?
Here are a few antique snuff boxes for inspration:
This last one was sold at Christie's for a whopping £121,250 June 2. I will go for something less pricey, I think. Maybe try and paint something myself!
P.S. Do yourself a favour and don't google for images with "snuff" as search query. There's some really nasty stuff out there...
