An expenditure analysis revealing how Philip Morris advertisements coincide with tobacco policymaking in Switzerland

Introduction Prior research has linked media tobacco promotion to increased tobacco use and favorable perceptions of tobacco products. Switzerland's tobacco lobby employs advertisements to sway policy decisions in its favor, yet no recent research has assessed this in detail. Our study aims to provide detailed estimates of tobacco industry (TI) advertisement costs, focusing on Philip Morris International (PMI) in Switzerland, and examine potential chronological links between TI advertisement campaigns and parliamentary discussions on tobacco bills. By spreading knowledge on this issue, we aim to support the development of future tobacco advertisement regulations.
