Its pretty natural to go for tobacco flavors after you stop smoking. I tried several other flavors, i can tell, i dont like much sweet tastes. Even tobacco juices arent real tobacco, in a real way, some mimics some scent or taste you have on tobacco smoke.
Take for example a cigarette i used to smoke, lucky strike. As all cigarettes, they put sugars on it. When you vape a tobacco juice like tribeca, it resembles, because its somewhat sweety. I really liked when i tried unflavored, to me it tasted most dry vape experience, you just taste and feels the nicotine, what is a more smoke like experience. From my shallow vape experience, is the nicotine added that make things looks like cigarettes.
