Relationship of drug use to involvement in school, home, and community activities: results of a large survey of adolescents.

All 7th, 9th, and 11th grade students in 129 school districts responded to a 466-variable survey that primarily assessed drug use but also contained questions about involvement in various activities. Meaningful relationships were obtained between students' involvement in school, family, and church activities and reported use of tobacco, alcohol, and marijuana. Factors reflecting the extent of parental supervision were also related to the reported use of those substances.
