Abstract (en)

[origin: EP0085494A2] The sidestream smoke emanated by a smoking article, such as a cigarette, can be significantly reduced by constructing the smoking article with a double wrapper, one of the wrappers having alkali metal salt burning additives in an amount in the range from about 9 to 20% by weight. A commercially feasible reduced sidestream cigarette can be produced according to this invention, having both wrappers made from a low-porosity flax base, with the inner wrapper containing 11% and the outer wrapper 6% potassium citrate.
