Estimates from multivariate regression models for trends in smoking onset by sex, race/ethnicity and annual cohort among adolescents and young adults who never smoked 12 months prior to the survey: NSDUH, 2006–2013. National Survey of Drug Use and Health (NSDUH) Never smokers were persons who reported “no” to ever smoking a cigarette 12 months prior to participating in the survey. Smoking onset was persons who reported smoking part or a whole cigarette for the first time within 12 months of the survey and doing so every day. Adolescents were persons between 12 and 17 and young adults between 18 and 25. Annual cohorts were adolescents or young adults at the year of the survey interview. Changes in smoking onset among successive cohorts of: (1) black adolescent males were different from white adolescent males at a statistically significant level. (2) black, Hispanic, and Asian adolescent females were different from white adolescent females at a statistically significant level. (3) black and Hispanic young adult males were different from white young adult males at a statistically significant level. (4) black and Hispanic young adult females were different from white young adult females at a statistically significant level.
