Abstract

Significant decreases in sidestream smoke production, approximately 30 to 70%, are obtained when compared to a tobacco filler rod wrapped in a conventional cigarette paper by double-wrapping the filler rod, first with a relatively non-porous paper having a Coresta porosity of about 1 to about 10% and then with a conventional cigarette paper.
