The article analyzes some dilemmas related to the implementation of the Framework Convention on Tobacco Control, underscoring the States parties' difficulties in adopting public policies with proven cost-benefit and aimed at reducing tobacco's supply and demand. Specifically, the article examines the recommendation to adopt policies for plain cigarette packaging, as provided in the guidelines for implementation of the Convention's Articles 11 and 13. Based on case analysis, we identified political and legal factors that hinder the Convention's implementation, including the regulatory chill produced by legal claims filed by the tobacco industry, which uses investor-State arbitration clauses from bilateral investment agreements. The article concludes that despite the costs imposed on States and the delays in the adoption of such policies, in the medium and long term the rulings handed down by the arbitration courts and the World Trade Organization's Dispute Settlement Body can consolidate the understanding of the legality and effectiveness of policies that adopt the model.
