Accelerated Adoption of Smoke-Free Laws After Ratification of the World Health Organization Framework Convention on Tobacco Control.

Abstract

We sought to evaluate the effect of ratifying the World Health Organization Framework Convention on Tobacco Control (FCTC) on countries enacting smoke-free laws covering indoor workplaces, restaurants, and bars. We compared adoption of smoke-free indoor workplace, restaurant, and bar laws in countries that did versus did not ratify the FCTC, accounting for years since the ratification of the FCTC and for countries' World Bank income group. Ratification of the FCTC significantly (P < .001) increased the probability of smoke-free laws. This effect faded with time, with a half-life of 3.1 years for indoor workplaces and 3.8 years for restaurants and bars. Compared with high-income countries, upper-middle-income countries had a significantly higher probability of smoke-free indoor workplace laws. The FCTC accelerated the adoption of smoke-free indoor workplace, restaurant, and bar laws, with the greatest effect in the years immediately following ratification. The policy implication is that health advocates must increase efforts to secure implementation of FCTC smoke-free provisions in countries that have not done so.
