Data derived from the National Survey of Drug Use and Health 2010-2013

Estimates weighted to reflect the US population

Logistic regression models – estimates are odds ratios with 95% confidence intervals (CIs).

Adjusted models controlled for age, race, education, marital status (persons 12 to 14 years old included in the unmarried category), poverty, and survey year. In addition to these covariates, the adjusted tobacco outcome model controlled for past month alcohol use, and the adjusted alcohol outcome model controlled for past month tobacco use.

Respondents with an unknown pregnancy status were included in the non-pregnant group (n=466)
