Impact of institutional smoking bans on reducing harms and secondhand smoke exposure

Cochrane Database of Systematic Reviews, June 2016

This Cochrane review aims to assess the extent to which institutional smoking bans may reduce passive smoke exposure and active smoking, and affect other health-related outcomes.

The study found evidence of an effect of settings-based smoking policies on reducing smoking rates in hospitals and universities. In prisons, reduced mortality rates and reduced exposure to secondhand smoke were reported. However, the reviewers rated the evidence base as low quality. The study concludes that more robust studies assessing the evidence for smoking bans and policies in these important specialist settings are needed.
