The sidestream smoke associated with a cigarette (10) or cigarette-like smoking article is reduced by wrapping the tobacco (12) in a double layer (18a, 18b) of paper. Each layer includes calcium carbonate and a burn control chemical. The outer layer (18a) also preferably includes monoammonium phosphate and sodium carboxy methyl cellulose. The calcium carbonate employed has a relatively high surface area per unit weight. The porosity of the outer layer is adjusted by electrostatic perforation.
