The absolute closest to this I found was a chemical mockup meant to taste like Parliment cigarettes. I have a link around here to order if you're interested. What was interesting was that when I first switched from cigarettes to it, it tasted fine. As time went on, my tastebuds cleared up, I began to notice that it tasted differently. Eventually the flavor outright nauseated me- it tasted absolutely nothing like burning tobacco. It only tasted like it while my tastebuds were still semi-deadened from smoking.
In short, if you look into the ecig enthusiast communities, you'll tend to notice that very few people vape tobacco flavors, and there's a very good reason for it.
