The U.S. Treatment Episode Data Set (TEDS) collects substance-involved admissions to treatment facilities that receive public funding. The recent TEDS report showed that cannabis was the most commonly identified primary illicit drug for treatment among blacks (29%), Hispanics (22%), and Asians/Pacific Islanders (21%); while the most commonly identified drug other than alcohol among whites was opiates (34%), followed by cannabis (12%) (SAMHSA, 2015). These drug-involved treatment data suggest that CUD may disproportionally affect minority groups. TEDS data reflect treatment admission encounters that can be influenced by the frequency of multiple encounters. Individual-level data thus are needed to better understand the prevalence of CUD among the growing racial/ethnic populations to inform research and clinical efforts on screening, intervention and referral to treatment for CUD. The National Survey on Drug Use and Health (NSDUH) provides the primary source of ongoing CUD data. The independent and cross-sectional 2005–2013 NSDUHs use similar designs to allow the analysis of the same variables from the pooled sample. The large sample of NSDUH also permits analysis to produce reliable CUD estimates for racial/ethnic groups with a smaller
