Progress and challenges in tobacco control policies in Mexico, 2003-2017: an approach using the Tobacco Control Scale.

The study aims to assess the implementation of tobacco control policies in Mexico from 2003 through 2017 using the Tobacco Control Scale (TCS). The TCS is a research tool widely used in the European region. It facilitates assessment of tobacco control policy implementation based on six cost-effective interventions: tobacco taxes, smoke-free policies, advertising bans, public spending on the information campaign, health warnings, and smoking cessation treatment, reflecting results in a total score between 0 and 100. From 2003 through 2017, Mexico's total score improved from 24/100 to 55/100, with substantial progress in raising tobacco taxes, 11 subnational smoke-free laws, and with placement on cigarette packs of large health warnings with pictograms. Progress in tobacco control policies implemented in this period corresponds with a decrease in smoking prevalence across Mexico. This tool is useful for monitoring tobacco policy implementation in low- and middle-income countries and be used for advocacy purposes to enforce and improve tobacco control legislation.
