In 1999, the Arizona State Legislature passed a comprehensive school-tobacco law that prohibits tobacco products on school grounds, inside school buildings, in school parking lots or playing fields, in school buses or vehicles and at off-campus school-sponsored events. The law applies to any K-12 public, charter or private school. Violation of the law is a petty offense. To document the extent to which Arizona public schools are in compliance with this legislation, the Arizona Cancer Center conducted the Arizona School Policy Survey as a project of the Tobacco Education and Prevention Program of the Arizona Department of Health Services. This survey was a follow-up to a similar survey completed in 1998.
