Notes: Chi-square tests were used for overall comparisons, with adjustments for multiple comparisons. Where differences were observed (α = .004), post hoc contrasts were conducted to identify specific group differences; groups with shared superscripts are significantly different from one another. Cell totals may not equal 100% because of rounding. NESARC = National Epidemiologic Survey on Alcohol and Related Conditions; DSM-IV = Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition; IUD+ = inhalant users with DSM-IV inhalant-use disorders; IUD– = lifetime inhalant users without DSM-IV inhalant-use disorders; inhalant nonusers had no lifetime inhalant use. All ns in column headings are unweighted values; table values are weighted column percentages (SEs).
