Pre-Conference Event- 10 June 2021: ENSP Scientific Webinar “Effects and Challenges in Enforcing Ban on Flavoured Tobacco Products” Adding menthol flavour to cigarettes masks the negative sensations of smoking, raising smoking uptake and reducing quitting. Thus it is not surprising that the tobacco industry and associates have attempted to prevent, delay and circumvent menthol and flavour bans globally. The objective of this presentation is to illustrate how this interference occurred pre and post the menthol ban which was part of the 2014 EU Tobacco Products Directive (TPD) legislation. The two European countries with highest menthol use pre ban are used as case studies. The main focus of the Poland case study is pre ban activity whereas the main focus of the UK case study is post ban activity. We conclude that the pre ban tobacco industry activity did impact the eventual legislation and we present recommendations to tighten the ban based on post ban tobacco industry activity. These recommendations include banning menthol as an ingredient and extending legislation to all tobacco products and accessories.
