Abstract
Extent and determinants of use of alcohol, marijuana, inhalants, and PCP were explored in a group of 339 Mexican American youths from the East Los Angeles Housing projects. Results from this study were compared to those from a similar survey carried out in the same area 2 years ago. Use of inhalants has declined markedly compared with prevalence reported in the previous report. However, use of alcohol and marijuana have increased across all age and sex cohorts. Prevalence of PCP use, explored for the first time in this report, was shown to be extremely high. Use of all drugs was generally predicted by age, sex, and number of peers reporting use. Self-concept factors, especially one's self-evaluation with respect to others, were also significant predictors to use of marijuana, inhalants, and PCP. However, alcohol use was not related to any self-concept factors. Language (Spanish-English) used both in the home and with peers was related to use of all substances studied. Limitations in the generalization of this study as a result of sampling problems are discussed.
