Final Opinion


SCHEER WG on Tobacco additives
SCHEER members: Emanuela Testai (Chair and Rapporteur), Raquel Duarte-Davidson, Peter Hoet, Theo Vermeire, Sergej Zacharov
External experts: Urmila Nair, Reinskje Talhout, (Rapporteur), Konrad Rydzynski
On request from: European Commission
Adopted on: 16 December 2016

Stemming from Tobacco Products Directive 2014/40/EU and from a previous SCENIHR Opinion (Tobacco Additives I), the Commission has established a priority list of 15 additives contained in cigarettes and roll-your-own tobacco subject to enhanced reporting obligations that is to be updated on a regular basis. For these additives included in the priority list, manufacturers and importers of tobacco products must carry out comprehensive studies.

In the second Opinion (Tobacco Additives II) the SCHEER was asked to provide guidance on the type and criteria for comprehensive studies, and the most suitable methodologies to be used for the first list of 15 priority additives and for future updated lists.

The SCHEER proposes a step-wise strategy as the most pragmatic and efficient way to proceed in the assessment of the toxic, and addictive effects as well as and characterising flavour properties and to minimise testing.

In addition, the SCHEER analysed major data gaps for the 15 additives included in the priority list of additives which generally relate to information on addictiveness and attractiveness, as well as on the identity of the pyrolysis products.
