Among alcohol users, 22.6% of Whites, 21.4% of Blacks, 26.7% of Hispanics, 16.9% of NH/PI and 29.0% of AI/AN transitioned to dependence at some time in their life (log rank test= 47.16, p<0.01). Half of the cases of alcohol dependence among Whites, NH/PI and AI/AN developed approximately 8 years after the first use, whereas among Blacks and Hispanics alcohol dependence developed approximately 16 years after the first use (Figure 2).
