A nose for tobacco (5)
I believe the answer is:
snout
I believe this is a double definition.
'a nose' is the first definition.
(snout is a kind of nose)
'tobacco?' is the second definition.
(snout can informally mean tobacco)
'for' is the link.
(Other definitions for snout that I've seen before include "Tobacco -- hooter" , "Animal's long, projecting nose" , "Pig's nose" , "Nose; tobacco (slang)" , "nose of pig" .)
