Comparison of smoking relapse curves among African-American smokers.

We examined the smoking relapse curves for African-American smokers by level of smoking to characterize nicotine dependence in this population of smokers. This analysis was conducted from data originally collected to study differences in level of smoking among African-Americans at an inner-city health center in Midwest. Relatively little research has been conducted to clarify smoking and quitting patterns among African-American smokers. The median number of cigarettes smoked currently was 7 cigarettes per day (cpd) for light smokers and 20 cpd for the moderate to heavy smokers. The heavier smokers reported smoking at this rate longer than light smokers, 11 and 5 years, respectively. The major finding in this study is that African-American light smokers have abstinence rates very similar to heavier smokers and the median length of their most recent quit attempts were also similar. Therefore, stable light smokers may also need smoking cessation interventions similar to those used for heavier smokers in order to successfully stop smoking.
