Reduced Benzo(a)pyrene and Phenolic Content of Smoke from Experimental Cigarettes

Abstract

THE properties of tobacco and non-tobacco leaves can be modified by subjecting these leaves to a series of chemical extractions which strip the whole leaf, or shredded leaf, to almost pure cellulose. This extraction process removes unhealthy substances and improves the flavour and aroma of such leaves when they are used as a smoking product. The extracted leaf is reconstituted, preferably to its original weight, by adding back non-toxic chemical agents which enhance the burning qualities, flavour and aroma.
