This article discusses the results of a survey of homeless adolescents in the Hollywood area of Los Angeles County. The survey was designed to yield a broad understanding of homeless youth, but it focused particularly on mental health and substance use issues -- problems for which homeless adolescents are considered to be at high risk. The authors present a descriptive summary of alcohol-related findings from the study, including (1) the prevalence and nature of alcohol use and abuse, (2) correlates of alcohol abuse, and (3) the alcohol treatment experiences of homeless adolescents.
