Existing literature suggests that Blacks and to some extent Hispanics are less likely than Whites to use substances in their youth. However, by age 35 their use rates are higher than those of Whites. This has been referred to as the race/ethnic age crossover effect in substance use. However, more research is needed to clarify whether this is true for Blacks and Hispanics, males and females, and for drugs and alcohol. It is also empirically unclear why this crossover effect occurs. The present study explores these issues. The National Household Survey of Drug Abuse is merged for four years (1999–2002) to study the race/ethnic age crossover effect (n = 208,878). The results suggest that the race/ethnic age crossover effect cannot be used to describe Hispanic relative to White substance use. However, it is applicable to Black substance use, in particular illegal drug use for Black males and heavy drinking for Black females. Additional analyses reveal that the crossover effect for Blacks is eliminated when socio-demographic controls are included. With controls, drug use and heavy drinking for Blacks are lower than that of Whites for all age groups and for both males and females. Process differences are also revealed in the effects of the socio-demographic correlates. More specifically, these analyses of composition and process suggest that drug availability/exposure is a particularly important factor which likely contributes to the crossover effect in substance use and deserves further study.

Research reveals that Black youth are less likely to use alcohol than White youth. It has been argued that Blacks are more likely to abstain because they have less disposable income, are more religious, and have more family support and/or control than White youth. It has also been suggested that not only are these compositional characteristics different and likely to suppress use rates but also that the effects of these factors vary as well. However, there are no comprehensive empirical investigations of these explanations. This study uses the Add Health Survey to examine alcohol and drug use by race and/or ethnicity and to explore how differences in composition and process might produce differences in use. Results suggest that the socioeconomic contexts of Black and White youth differ considerably. However, differences in alcohol use are almost entirely explained by differences in process, in particular, the influence of peers and the family.
