    Objective: The objective of the ITC Project is to evaluate the impact of tobacco control policies as they are being implemented throughout the world. The ITC project helps to study how tobacco control policy measures ultimately impact on smoking behavior and how this is mediated by changes in the perceived social and physical environment. More specifically, the aims of the study are to evaluate the effect of specific tobacco control policy measures on smoking cessation and to uncover factors that hinder or strengthen the effectiveness of policy measures and hinder or strengthen the implementation of new measures in the Netherlands.

    Method: The International Tobacco Control (ITC) policy evaluation project conducts longitudinal cohort surveys in more than 20 countries. Since 2008, a cohort of tobacco smokers is being followed with yearly survey waves in the Netherlands.

    Results: With data from the ITC Netherlands Survey, we have evaluated the impact of smoke-free legislation, mass media campaigns, health warning labels, reimbursement of smoking cessation aids, and tax increases. The coming years, we plan to evaluate the impact of European regulations that are being implemented from 2016 forwards and include the implementation of pictorial health warnings and stricter regulations for electronic cigarettes.
