The Arizona Youth Tobacco Survey is a series of biannual school-based tobacco-focused surveys first implemented in the spring of 2000. The survey is designed to help monitor trends in tobacco use among public school students in grades 6 through 12 and to compare changes in rates over time. The survey also collects data on topics including: tobacco use; tobacco-related knowledge, attitudes and beliefs; access to tobacco products; exposure to environmental tobacco smoke; initiation and cessation; influence of family, friends and the media; and social, school and community interventions.
