May I ask, what do you wish to duplicate? "Tobacco" flavor is in the leaf, the variety, the growing & harvesting technique, the curing process, and even the weather from the time it was set until it was primed. Cigarette flavor is largly influenced by the filter used with the tobacco chosen and of course by the additives used to duplicate the same "brand taste" pack after pack, production after production. At auction, tobacco buyers look for the quality of the leaf, smell, texture, and so forth and bid to produce more than just cigarettes. Are you looking for "tobacco", or are you looking for "cigarette" flavor? Tobacco can be found in many true flavors with as much variety as the real thing, cigarettes, however could be much more difficult to simulate, especially if you're trying for a specific brand.
