Abstract
This invention relates to a tobacco treatment in which the perceived strength of tobacco smoke is improved by treatment of acidic tobacco with a material which remains essentially inactive until the tobacco is burned. The treatment is particularly effective on acidic tobacco to be employed in high filtration cigarettes which deliver reduced amounts of tar and nicotine.
