Tobacco Free Initiative (TFI)

Protect people from exposure to second-hand tobacco smoke

Evidence and best practices

Benefits and outcomes of creating 100% smoke-free environments

  • Implementation of smoke-free policies leads to a substantial decline in SHS exposure.
  • Implementation of smoke-free legislation causes a decline in heart disease morbidity.
  • Implementation of smoke-free legislation decreases respiratory symptoms in workers.
  • Smoke-free workplaces reduce cigarette consumption among continuing smokers and lead to increased successful cessation among workers.
  • Smoke-free policies do not cause a decline in business activity of the restaurant or bar industry.
  • Smoke-free policies reduce tobacco use among youth.

There is extensive evidence from a number of countries that comprehensive smoke-free laws prompt people – and particularly parents – to make their homes smoke-free. In New Zealand, reported exposure to second-hand smoke in the home nearly halved in the three years after smoke-free legislation was introduced, and in Scotland, children’s exposure to second-hand smoke fell by nearly 40% after smoke-free legislation came into force.
