Whereas once smoking was commonplace in the working environment, in shopping centres, on public transport, in restaurants and elsewhere, public health concerns about exposure to second-hand smoke have led to the introduction of clean air acts and other smoking restrictions at the national, state, and local government level. Most workplaces, schools, and other public places are now smokefree, and increasing numbers of Australian households have chosen to ban smoking in their homes125 (see Chapter 4, Section 4.12 ). Bans on smoking at home appear to be particularly important in influencing smoking behaviour among teenagers.78
As well as physically reducing the places where smoking may occur, reducing opportunity to smoke and restricting the kinds of places in which people may smoke also helps challenge perceptions that smoking is normal behaviour.126 Recent publicity supporting bans on smoking in cars is likely to strengthened this view. For further discussion see Section 5.29 and Chapter 15, Section 15.6.1 .
