I don't think I ever saw anyone identify a brand just by the smell. it's impossible. most brands from the same parent company are made at the same factory from the same batch of the same chemical-soaked tobacco pulp. it's just the filters and packages that are different. when I smoked, chesterfields, l&ms, pall malls, winstons, parliaments, etc, all tasted and smelled the same to me. only the cheapest godawful local brands smelled different than the rest.
