Abstract Population-level public health policies aim to improve health for the entire population. Yet, in doing so, they may unintentionally neglect vulnerable populations' specific needs, which may perpetuate social inequalities in health. As an example, tobacco control policies (e.g. media campaigns, smoke-free places, tax increases, and tobacco product regulation) have been found to significantly reduce overall smoking prevalence in many high-income countries. However, social inequalities in smoking have been increasing, with smoking prevalence being higher, notably for those of low socio-economic status (SES). Low SES individuals start smoking at younger ages, smoke more cigarettes per day, have lower cessation rates, and are exposed to more second-hand smoke than higher SES individuals. These social inequalities in smoking translate into social inequalities in health such that low SES groups carry a disproportionately heavier burden of smoking-related illnesses. Based on data from a critical discourse analysis of tobacco control policy in Quebec, Canada, as well as from a literature review of vulnerable populations' experiences with tobacco control policies, this presentation will: 1) illustrate ways in which tobacco control policies may be increasing social inequalities in smoking, including the absence of vulnerable populations who smoke from policy planning, smoking denormalization's unintended stigmatizing effects, and targeting behaviours rather than the 'causes of the cause' in policy; 2) provide ideas for future population-level policies based on a health equity approach, which includes integrating vulnerable population's voices in policy design, prioritizing vulnerable populations and health equity in policy, and shifting attention towards policies addressing social inequalities in access to social determinants (e.g. education, income, employment security, safe, clean, and affordable housing) to improve health rather than targeting behaviours, such as smoking.
