Pub workers in Scotland breathed easier and showed better respiratory health shortly after a nationwide ban on smoking inside public places went into effect earlier this year, scientists report.
Other research had suggested that worker health improves after a smoking ban, but this is the most comprehensive study to date, says pulmonologist Daniel Menzies of the University of Dundee.

The volunteers submitted to breathing tests, blood sampling, and health interviews. The researchers repeated the exams 1 month and 2 months after the ban took effect.
