The epidemiology of alcohol, marijuana, and cocaine use among Mexican American, Puerto Rican, Cuban American, and other Latin American eighth-grade students in the United States: 1991-2002.

OBJECTIVES: We compared trends in and correlates of marijuana use, cocaine use, and heavy alcohol use for adolescents of Mexican American, Puerto Rican, Cuban, and other Latin American heritage in the United States. METHODS: We used/examined data from nationally representative samples of eighth-grade Hispanic students who participated in the Monitoring the Future study during the years 1991-2002 (n=24235). RESULTS: Drug use was significantly higher among boys and adolescents of almost all Hispanic ethnicities who did not live with both parents. In addition, drug use differed considerably according to ethnic group on language first spoken, parental education, urbanicity, and region. CONCLUSIONS: A better understanding of the homogeneity and heterogeneity of drug use patterns within and between Hispanic groups should assist in the development of prevention programs.

Tobacco, alcohol, and illicit drug use: racial and ethnic differences among U.S. high school seniors, 1976-2000.

OBJECTIVE: This study examines differences in adolescents' use of tobacco, alcohol, and illicit drugs by racial and ethnic groups. METHODS: The authors analyzed questionnaire data from large, nationally representative samples of U.S. high school seniors to examine differences in drug use prevalence and trends among racial and ethnic groups between 1976 and 2000. RESULTS: On average, American Indian seniors showed the highest levels of tobacco, alcohol, and illicit drug use. Cuban American and white seniors also tended to have relatively high levels of substance use, followed by Mexican American and Puerto Rican seniors. Other Latin American, African American, and Asian American seniors reported the lowest levels of drug use. Most of these differences are longstanding, but some have widened and others narrowed during the past 25 years. CONCLUSION: Significant differences exist in adolescent use of tobacco, alcohol, and illicit drugs by racial and ethnic groups, and these differences have changed over time. Future research should examine these differences and seek to identify the sources and consequences of the disparities.
