A new study predicts that smoking bans and other tobacco control policies will prevent the premature deaths of an estimated seven and a half million people worldwide by 2050.

Researchers at Georgetown University Medical Center inWashington, D.C. looked at 41 countries that had implemented tobacco control measures since 2007.

The study's results show that successful tobacco control measures include smoking bans, quit helplines, bans on tobacco advertising and higher cigarette taxes.

In addition to saving lives, the tobacco control policies lead to other health benefits such as fewer adverse birth outcomes and reduced healthcare costs.

The study was published in the Bulletin of the World Health Organization on Sunday.
