Chapter 8 turns to a paired comparison of secondhand smoke prevention policies, which offer a more optimistic picture of sociolegal change. In addition to more nonsmoking rules, changing social norms and declining smoking rates were conducive to realizing reforms—and benefited from them. This chapter details the contributions of tobacco control advocates through lobbying, educational activities, and lawsuits related to secondhand smoke, especially in workplaces and at subnational levels. Their multi sited activism is a necessary part of understanding why one is now much less likely to be exposed to secondhand smoke in Korea and Japan.
