Abstract

Health warnings and messages—or health warning labels (HWLs)—are integral to tobacco control efforts, but their sustained impact necessitates regular rotation. This paper explores challenges in HWL rotation implementation across six diverse countries: Chile, Guyana, Indonesia, Jamaica, Mexico, and Vietnam. 19 in-depth interviews were conducted with government officials and representatives from civil society organisations and academia. Interviews explored the effectiveness of HWL regulations, the processes involved in their execution, and any challenges encountered along the way. Interviews were analysed thematically, using a combination of deductive and inductive approaches. Interviews revealed critical challenges that fall into two categories: specific and overarching. Government priorities and transitions, political will, time and bureaucracy, legal loopholes, lack of images, evaluation, and economic and human resources constitute HWL-specific challenges. Broad tobacco control challenges included tobacco industry interference and enforcement difficulties. To address HWL rotation challenges, international bodies such as WHO could establish extensive image banks, pre-evaluated for effectiveness and cultural relevance. In addition, countries must institutionalise the rotation process by establishing mechanisms that avoid having to pass complex legal instruments with each new round of warnings, delegating responsibilities to stable government institutions, addressing legal loopholesand planning for multiple rounds within a single legal instrument. Further, partnerships at national and international levels, along with systematic evaluations, are crucial for successful HWL implementation. These recommendations form a comprehensive framework for global collaboration, aiming to strengthen tobacco prevention through impactful HWLs on a sustainable basis.
