The Joint Action on Tobacco Control (JATC) was launched in October 2017. This comprehensive EU funded project aims to provide support for the implementation of the Tobacco Products Directive (TPD) across the 28 EU Member States. The TPD is a complex legislative document that lays down the rules governing the manufacture, presentation and sale of tobacco and related products, while also supporting the functioning of the internal market of tobacco products in the EU. The JATC addresses the issue of tobacco product monitoring at an EU wide level through facilitating access of data within the EU Common Entry Gate (EU-CEG), assessing tobacco and e-cigarette product compliance to the TPD, assessing aspects of laboratory harmonisation and evaluating the role of priority additives in tobacco products. This 36-month project operates with 9 Work Packages and involves 30 Partners and an additional 13 Collaborating Partners, an activity that would be impossible to be done by one, or a few, EU MS by themselves.
