A half-century after the federal government recognized the dangers of tobacco, substantial progress has been made in controlling its use in the United States. The prevalence of smoking has been halved from its peak and the majority of Americans work and live in smoke-free environments. Progress has also been made elsewhere, but in many low- and middle-income countries, prevalence of tobacco use continues to increase. Despite progress, much is unfinished in tobacco control worldwide.
