Abstract
A cigarette includes a charge or roll of smokable material (e.g., tobacco cut filler) circumscribed by two layers of paper wrapping materials. The first or inner wrapping material includes a cellulosic base web, tobacco, and magnesium oxide and/or magnesium hydroxide within the web. The second or outer wrapping material circumscribes and overwraps the first wrapping material, has a cellulosic base web and inorganic filler material, and exhibits an air permeability of below about 8 CORESTA units. The cigarette is capable of sustaining smolder under FTC smoking conditions while yielding very low levels of visible sidestream smoke.
