What do you think tobacco companies add flavors to cigarettes that make the cigarettes taste and smell sweet ?

Sugar is naturally moisture-absorbing, and here it not only absorbs the flavoring, it also sticks to the tobacco and absorbs some of its moisture too, holding the flavoring onto the leaves in the process. And when smoked, the sweetness of the sugar helps make the other flavors seem more pleasant as well.
