Snuff is probably culturally significant. Despite never knowing anyone who takes snuff you still read about snuff and snuff boxes. In fact I seem to recall that some people still call the webbing between your thumb and index finger the "snuff box" because that's where people would put the snuff before insufflating it.
I would imagine snuff boxes / accessories now days are bought more by people who snort illegal drugs than tobacco and the name remains as a PR thing (shops, even head shops with weed art in the window, don't want to advertise things like "cocaine snorter"). But I've no idea how many people still exist that use actual snuff.
