Abstract
A chewable smoking substitute composition is disclosed which comprises about 15 to about 80 percent gum base and a nicotine cation exchange resin complex dispersed in the base. The cation exchange resin complex constitutes up to about 10% of the chewing gum composition and affords a nicotine release, when chewed, of approximately that available when smoking a conventional cigarette.

1. A CHEWING GUM BASE AND
-
2. nicotine, held by a saliva-insoluble cation exchanger, wherein the cation exchanger is selected from the group consisting of a) methacrylic type, weakly acidic, containing carboxylic functional groups;
- b) polystyrene type, strongly acidic, containing sulfonic functional groups; and
c) polystyrene type, having intermediate acidity, containing phosphonic functional groups;
substantially uniformly distributed in said chewing gum base, wherein;
A. the composition is in the form of a chewable gum unit weighing in the range of about 0.5 to about 4 grams;
B. the chewing gum base is present in said gum composition in an amount in the range of about 15 to about 80 weight percent of said gum composition;
C. the nicotine is present in said composition in an amount in the range of about 0.05 weight percent to about 2 weight percent based on the weight of the chewing gum base and calculated as the free base;
D. the amount of nicotine held by the cation exchanger and distributed in said chewing gum base is in the range of about 1 to about 10 milligrams, such amount of nicotine approximating the amount available upon smoking a smoking tobacco product;
E. said nicotine-cation exchange complex constitutes up to about 10 percent by wEight of said chewing gum composition;
F. the nicotine is present in said nicotine-cation exchange complex in an amount in the range of about 2 to about 60 percent by weight;
G. the nicotine held by said saliva-insoluble cation exchanger being present in said gum composition as a nicotine-cation exchanger complex which upon chewing liberates the nicotine cation, and H. said chewing gum composition when chewed releasing nicotine in small and reduced amounts within a period of the first few minutes of chewing, and I. especially within the first ten minutes of chewing releasing the nicotine at a rate less than if the nicotine were present by itself in an ordinary gum composition and less than if the nicotine-cation exchanger complex were used by itself absent the gum.
- b) polystyrene type, strongly acidic, containing sulfonic functional groups; and
-

-
4. The chewing gum composition of claim 3 wherein the amount of nicotine held by said cation exchanger and distributed in said chewing gum base is in the range of about 1 to about 5 milligrams, such amount of nicotine approximating that available upon smoking a cigarette.
