This may not be news to anyone, but a study was done by some doctors (D. Pfaue, M. Tisch and H. Maier) called “Krebs durch Schnupftabak?” (Cancer from snuff?) and published in 2003 - it’s available online for a hefty fee (50-something US dollars). They found no evidence of any carcinogenic components, except for some nitrosamines, which occur at a much lower rate in snuff than in tobacco smoke and can be reduced by conscientious snuff manufacturers. The risk is also reduced because snuff generally exists the nostrils when one blows one’s nose, though regular use may irritate the nasal passages. Also, the EU downgraded the dangerousness of nasal snuff on 30 September 2002, which means that snuff packaging could no longer contain warnings about cancer but only warnings concerning cardiovascular risk and addiction potential. Even so, for some reason, some of my Silver Dollar snuff tins still have a cancer warning on them (and others mention gum disease and tooth loss - erm, no, I ain’t dipping the stuff). I guess the EU has higher standards when it comes to scary health warnings. As far as I know, this is all we know about the effects of snuff on health. Obviously, nicotine is addictive, but, as pointed out in another topic, many studies do not separate out nicotine use from cigarette smoking, and most of the rest seem to be on lab rats rather than on human test subjects. I, for one, would like to see some scientists administering snuff to people (sign me up!). This doesn’t mean we’re all in the clear for certain, but it’s good to know that snuff really is the least risky form of tobacco to the best of modern medical knowledge. So there! 
Silver Dollar snuff has the odd cancer warnings because it is sold in B&M in the US. The US government requires cancer warnings on snuff. I think mostly because they think that since it’s tobacco it’ll kill ya.
and no mention of the health benefits, which are well established. Go figure. Sad that truth is not a high priority.
Finally, something I enjoy that’s not going to kill me

This is because the US FDA does not recognize the nasal snuff or the nasal use of snuff, at least in this country since the use died out many years ago. As far as they are concerned all smokeless tobacco is simply oral tobacco. Toque had to go to great lengths to get FDA approval, and this was one of them, ridiculous as it is. It is worth noting that the older Dean Swift snuffs which were exclusively sold at B&M establishments since the 1960s had absolutely no warning on them.
Have a pinch or two in honor of the healthiness of snuff!
