Phased-in smoke-free workplace laws: reported impact on bar patronage and smoking, particularly among young adults in South Australia

OBJECTIVES: To measure the reported impact of phased-in smoke-free bar laws on bar patronage and smoking behaviour, particularly among young adults. METHODS: Cross-sectional survey of a representative sample of 2,004 South Australian adults, conducted four months into Phase I of the new laws. A comparable survey was conducted in 2003. RESULTS: Awareness of and support for the smoke-free laws were high. Phase I of the new laws did not reduce patronage. Young adults (18-24 years) reported higher patronage of bars and greater impact of the new laws on patronage, current smoking and future likelihood of quitting. CONCLUSIONS AND IMPLICATIONS: Smoke-free laws are an effective public health measure to protect against second-hand smoke. Evidence is now emerging that they may also reduce smoking among young people, as bars are social settings with potential to alter social norms about smoking and promote reduced consumption and quitting.
