You are never going to find it, some come close but they all still seem to be missing something. Tobacco has an inherently sweet flavour that some people don't like, others try to mask it and make it drier, the fact is that nobody can replicate the taste of smoking, because we don't know what is in tobacco now.
You are never going to find a good tobacco flavour that seems like a burning cigarette, you best bet is to find a flavour you like and replace the tobacco flavour for that. After a week or 2 real cigs will taste like Crap and you won't want anything even remotely like them. I know that everyone wants a cig a like, and everyone wants it to taste like a cig, but once you get over it, and vape a flavour you enjoy cigs will get grosser and grosser until they actually make you sick. If you get a tobacco get 2 desserts you might like. By the time those 3 bottles are gone Tobacco is the last thing you will want.
