Book excerpt: The report "Monitoring tobacco use and prevention policies" tracks the status of the tobacco epidemic and interventions to combat it. The report finds that more countries have implemented tobacco control policies, ranging from graphic pack warnings and advertising bans to no smoking areas. About 4.7 billion people - 63% of the world's population - are covered by at least one comprehensive tobacco control measure, which has quadrupled since 2007 when only 1 billion people and 15% of the world's population were covered.
