RE: alcohol
It may be somewhat true that it's used as a "homogenizer" but it's real purpose rests with flavorings and colorings. I don't work in the tobacco industry, but I work with companies that manufacture food-grade flavorings, fragrances, and dyes. They are sold to companies at extremely concentrated levels. It would not be economical to ship them in a ready-to-use concentration. So these companies get a very concentrated caramel color and vanilla flavor, etc. and dilute it in some form of alcohol so that it's in a concentration and consistency easy to apply to the tobacco.
Once diluted, they can easily apply the color/flavor evenly across the batch, and the alcohol will evaporate quickly. No need to worry about alcohol consumption for religious reasons, etc. Even in the unlikely scenario some alcohol remained in the tin/pouch, it would evaporate as you're loading your bowl. In the even more unlikely event some remained after you loaded your bowl, the alcohol would vaporize instantly from the heat of your match/lighter.
With all due respect, guys like Russ and Greg have been telling us for years that none of us are smoking "all natural" tobacco. There might be a couple blends out there, but almost every tobacco is going to have at least some kind of casing to help sweeten it, even if just a tad, no matter how much they advertise "all natural tobacco taste". You should really just be reading that as "no cherry/vanilla/chocolate flavor, but we're still adding a pinch of sugar and humectant because it would taste like crap and arrive as dust if we didn't".
