Snuff is just the English name, and can refer to nasal snuff, dip, pouches. Just means it’s ground up tobacco and isn’t anymore specific than that. Regionally it means whatever way of using it is most common.
Basically it’s confusing in the same way if you ask and American or European about football. Technically the word is not specific but it has very strong regional definitions

Snus refers to Swedish pouches with boiled (or somehow sanitized, can’t remember exactly) tobacco, as opposed to other kinds. Snuff can refer to stuff you put under your lip or up yer nose.
I see it's still legal in .de, and according to wikipedia has no tobacco-taxes on it since 1993! The real stuff, not only that white grapesugar/menthol stuff.
