This volume reviews the evidence critically appraised by a Working Group of 17 scientists from nine countries and draws conclusions about the effectiveness of smoke-free policies. The volume covers the evolution of smoke-free policies, impact of smoke-free policies on businesses in the hospitality sector, public attitudes towards smoke-free policies and compliance, reductions in exposure to secondhand smoke and effects on health due to restrictions on smoking following policy implementation, effects of mandated smoking restrictions on smoking behavior, and the effects of voluntary home smoking restrictions on exposure to secondhand smoke and smoking behavior. This handbook will be useful for health professionals and policymakers in countries who are currently considering legislation to protect the population from tobacco.
