THE RESURVEY WAS CONDUCTED TO ASSESS HOW THE USE OF DRUGS HAS CHANGED AND WHAT CURRENT ATTITUDES TOWARD DRUG USE ARE, TWO YEARS AFTER THE ORIGINAL SURVEY. IN THIS STUDY OF THE INCIDENCE AND PREVALENCE OF DRUG USE AND ABUSE AMONG IOWA'S RURAL RESIDENTS, 39 PERCENT OF THE 280 RURAL FAMILIES SURVEYED IN 1974 RESPONDED TO THE 1976 RESURVEY. APPENDIXES CONTAIN COPIES OF THE RESURVEY QUESTIONNAIRE AND THE COVER LETTERS ACCOMPANYING IT. FOR STATISTICAL REPORTS FOR THE ENTIRE RESURVEY, SEE NCJ-35529 THROUGH NCJ-35533.
