This review indicates very little research has examined the interrelationships of addictive behaviors among US ethnic groups. We summarize the overall findings in Table 1. In Table 2, we show results from NESARC-I, which has provided the most comprehensive recent set of publications on addictions and their comorbidities in US ethnic groups. Overall, our findings from this review suggest differences among US ethnic groups in rates of use, in prevalence of addictions, and in prevalence of addiction among those who use substances or engage in gambling.
