Cigarette flavor can be, and has been done. Three times, that I know of. I looked long and hard years ago and found a flavor called "Clay Westwood" from the "Adam" lineup by Eve E-liquid. Only place I can find it now is Zamplebox, which would lead one to believe it's no longer in production.
2nd prize goes to "M Type" by The Plume Room. It's actually a better flavor, but less of the smoked tobacco flavor than you got in Westwood. That one I know is still being made.
Big Spirit from Naturally-Extracted-Tobacco is the third. They use some kind of spice in with the tobacco extract that gives it that burning flavor. That being said, IMO it tastes like a stale generic cigarette. Worth a shot though.
A close, but no cigarette runner-up would be Huntsman from Heather's Heavenly Vapes. However, it has none of the Smokey taste. It's just a tobacco that has a very similar profile to cigarette tobacco.
I wish you luck. I went on the same flavor journey about 6 years ago. These are the liquids it brought me to. I've moved on from that flavor profile, so I can't help you with any newer ones that have come along in the past couple years, but I hope you can try one of these and enjoy them like I did years ago.
