They are part of a series of 14 fact sheets on tobacco additives written in the context of the EU project Public Information Tobacco Control (PITOC). The fact sheets aim to inform the public on the general uses, tobacco industry uses and harmful health effects of selected tobacco additives.
The German Cancer Research Center (DKFZ) also prepared seven fact sheets on the tobacco additives menthol, carob bean, cellulose fibre, prune juice, vanillin, guar and licorice, of which the electronic version can be found on the DKFZ website.
This initiative has received funding from The European Union in the framework of the Health Programme.
