Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Given that the pictorial health warnings (PHW) on cigarette packs need to be renewed, this project will provide highly policy-relevant and timely scientific evidence on the effect of new PHW policies in Vietnam. Additionally, this project would be the first to address the research gap in understanding the effect of adding quitline information to PHWs-a gap not explored in previous studies. With the potential for significant outcomes, the findings will help Vietnamese policymakers enact stronger PHW policies in upcoming years, aiming to increase perceived harms of smoking and foster smoking cessation, ultimately saving millions of lives in Vietnam
