ABSTRACT:
A cigarette having a region having means to reduce the vapour phase constituents of tobacco smoke, such as carbon, surrounding a tobacco smoke flow path is provided with ventilation means to channel the tobacco smoke away from the vapour phase constituent reducing region. The vapour phase constituent reductions achieved are greater than the reduction which would be expected in view of the degree of ventilation to which the cigarette is subjected.
