Four out of five U.S. adults report having voluntary smoke-free rules in their homes and three out of four report having voluntary smoke-free rules in their vehicles, according to a study published in the journal Preventing Chronic Disease, a publication of the Centers for Disease Control and Prevention (CDC).
National Adult Tobacco Survey respondents were classified as having smoke-free rules if they never allow smoking inside their homes or vehicles.
