Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for reducing the content of nitrosamines (e.g., N'-nitroso nornicotine, 4-(methyl nitrosoamino)-1-(3-pyridyl)-1-butanone, N'-nitroso anatabine, and N'-nitroso anabasine) in tobacco. SOLUTION: In one embodiment, the method includes combining tobacco with a solvent (e.g., water and/or other compounds) to form a soluble portion. The soluble portion contains an initial total level of tobacco-specific nitrosamines per gram of the soluble portion. The soluble portion is contacted with a nitrosamine-reducing material such that the resulting weight percentage of the tobacco-specific nitrosamines per gram of the soluble portion is at least about 20% less than the initial total level of the tobacco-specific nitrosoamines per gram of the soluble portion.
