OR represents odds of substance use relative to heterosexual adults of the same age and gender. Bold denotes statistically significant at the 0.05 level. Lifetime OR estimates are adjusted for race/ethnicity, education level, and urbanicity; past-year OR estimates adjust additionally for marital status, employment status, and living with children. All prevalence and OR estimates are weighted to account for the National Survey on Drug Use and Health survey design.

Testing magnitude of disparities across age cohorts:

^aSignificant difference between 18–25 years and 35–49 years.

^bSignificant difference between 18–25 years and 26–34 years.

^cSignificant difference between 26–34 years and 35–49 years.
