Whites were more likely than Blacks to engage in any smoking, in males (Table 1) and females (Table 2), at Waves 1 through 3; by Wave 4, there was no significant difference in any smoking among men (OR=1.17, 95% C.I. 0.95-1.44) though there remained a substantial difference among women (OR=2.93, 95% C.I. 2.14-4.03). Among smokers, Whites also smoked more cigarettes on average at all waves. The magnitude of the relationship between race/ethnicity and tobacco use generally decreased across time. For example, among males, Whites had 2.6 times the odds of smoking in the past month at Wave 1 (95% C.I. 2.0-3.4), but 1.17 times the odds of smoking in the past month at Wave 4 (95% C.I. 1.0-1.4).
