[57] ABSTRACT 



Cigarettes having incorporated therein a salt such as 

 nicotine levulinale exhibit low FTC "tar" to nicotine 

 ratios while (i) having a smooth, palatable, flavorful 

 taste, and (ii) providing smoking satisfaction to the user. 

 The cigarettes do not exhibit a harsh or irritating char- 

 acter; and do not exhibit a non-tobacco or off-taste.
