Apparently 'Snuff' refers to tobacco
Welcome to the site, pandasthumb.
Snuff (the stuff you stick up your nose) is certainly sometimes made of tobacco. But the title 'Snuff' is somewhat ambiguous I think and we'll have to wait and see what Terry does with it.
It could mean 'to extinguish', 'to murder' or maybe 'Up to snuff' as in good health.
