The World Health Organization (WHO) Framework Convention on Tobacco Control (FCTC) stands to significantly reduce tobacco-related mortality by accelerating the introduction of evidence-based control measures. However, the extend to which States Parties have implemented the Convention varies considerably. Article 5.3 of the FCTC, is intended to insulate policy-making from the tobacco industry´s political influence, and aims to address barriers to strong implementation of the Convention associated with tobacco industry political activity. This paper quantitatively assesses implementation of Article 5.3´s Guidelines for Implementation, evaluates the strengh of Parties´s efforts to implement specific recommendationes, adn explores how different approaches to implementation expose the policy process to continuing industry influence.
