I diy my juices and in my quest to find a juice that tastes like tobacco, I found only one. (TFA) Tobacco flavoring. (Light brand was ok too, though weak)
All others were too sweet, pungent, or tasted like caramel.
It surprised me to find the (TFA) Tobacco flavor unsatisfying even though I liked the flavor. I finally realized that cigarettes actually don't taste good and have a bad aftertaste that I'd learned to associate with the satisfaction of nicotine. I added a Hint of Captain Black to give my recipe a slightly unpleasant aftertaste and It did the trick, satisfaction achieved, especially after meals or with coffee. I've become accustomed to unpleasant aftertaste and don't notice it anymore.
Every says or will say you won't find one that taste like tobacco, Not True. You won't find one that tastes like tobacco that is pleasant tasting.
Just a heads up.
