We conducted a secondary analysis of Eurobarometer survey data from 27 European countries, collected in 2017 (n = 28 300) and 2023 (n = 26 358), to assess changes in public support for standardised tobacco packaging. In the pooled analysis, support remained unchanged in the 19 MS without relevant legislation (adjusted Prevalence Ratio [aPR]=0.94, 95% Confidence Interval: 0.86-1.03), whereas the 8 MS that had implemented the policy by 2023 were significantly more likely to experience an increase in support (interaction term: aPR = 1.28, 1.17-1.41). The increase in support offers reassurance to policymakers advocating for tobacco packaging regulations and encourages MS to consider the adoption of similar policies.
