D2.3 evaluates the implementation of EU tobacco control directives across EU and non-EU countries within the 4P-CAN Consortium, assessing policies, regulations, and enforcement levels. While all participating countries are parties to the WHO Framework Convention on Tobacco Control (FCTC), significant disparities exist, particularly between EU and non-EU nations, in taxation, smoke-free policies, health warnings, advertising bans, and cessation programs. Findings highlight that stronger tobacco control measures correlate with lower smoking prevalence and higher quit rates. Key recommendations include raising excise taxes, reducing cigarette affordability, expanding cessation services, implementing plain packaging, and enforcing stricter regulations to support the EU’s goal of a “Tobacco-Free Generation” by 2040.
