If you go by what w see infilms. It would be the rich and famous that used snuff. It was always noblemen we see flourishing their wrists. I take you to The Crimson Pirate, when Ohho uses it when inpersonating a nobleman when trying to release El Libre. Or The Scarlet Pimpernel. I believe I saw it another time in a pirate film but can't recall. Just me observation.
