Wave 2 NESARC respondents (N = 34,653) were 47.9% male and 70.9% Caucasian, with a mean age of 48.2 (standard error (SE) = 0.2) years. To aid in contextualizing results, we refer readers to Grant et al., 2009 for a fuller description of the sample, including prevalence of current psychiatric disorders. After excluding respondents who met DSM-IV criteria for current alcohol or non-cannabis substance use disorders, the sample was composed of 74 respondents meeting criteria for current CUD + ND, 100 respondents meeting criteria for current CUD only, and 3,424 respondents meeting criteria for current ND only. Table 1 shows sociodemographic characteristics of respondents. Of current CUD + ND respondents, 60.3% were male, 73.4% were Caucasian, 79.0% had a high school education or greater, 74.3% were employed at least part-time, and 39.3% had never been married; on average, they were 33.1 years old [standard error (SE) = 1.7]. Relative to respondents with ND only, respondents with CUD + ND were significantly younger and more likely to have never been married. Respondents with CUD + ND did not differ in sociodemographic characteristics from respondents with CUD only.
