Teenage smoking in Ireland down 20% since the 2004 smoking ban

In March 2004, under the Public Health Act, Ireland became the first country to ban smoking in the workplace. Since then, smoking in all enclosed public buildings has been banned. New research suggests this has contributed to a reduction in smoking prevalence among 16-year-olds from 33% in 2003 to 13% in 2015. Smoking prevalence fell by 65% among women, compared with a 46% reduction among men over the same period.
