Abstract

A cigarette is provided with a tobacco rod including a tobacco filler. The tobacco filler includes stemmed tobacco leaf shreds, and also includes a metal carboxylate salt selected from a metal lactate salt, a metal tartarate salt, a metal succinate salt, a metal 3-hydroxybutyrate salt, a metal acetate salt and a metal formate salt in an amount of 0.5 to 6.0% by weight of the weight of the stemmed tobacco leaf shreds.
