The purpose of this case study was to examine random student drug testing in one school district relevant to: (a) the perceptions of students participating in competitive extracurricular activities regarding drug use and abuse; (b) the attitudes and perceptions of parents, school staff, and community members regarding student drug involvement; (c) the perceptions of high school parents regarding random student drug testing and its impact on drug and alcohol use; and (d) the patterns and analyses of data collected regarding the use of random student drug testing as a preventative tool. Both quantitative and qualitative data were collected for inclusion in an analysis of the study in order to strengthen the results. The findings indicated that during a period of grant funding, the use of drugs decreased during a program of random student drug testing in the public school district studied. Furthermore, the random student drug-testing program initiated discussion among parents, school staff, community members, and students regarding drug use, community resources, and the importance of early intervention.
