Flavours in e-cigarettes: Public health issues and regulatory challenges

Flavours in e-cigarettes exert multiple points of influence across a range of health-relevant issues, from youth initiation to discontinuation of tobacco use among adults. Flavours also continue to be an important consideration in regulatory approaches to vaping products. National and subnational jurisdictions around the world have various regulatory authorities to address flavoured e-cigarettes in a number of ways, ranging from packaging and labelling rules, to restricting the use of specific flavourings via product standards, and as far as banning characterising flavours in all vaping products. This presentation will bring together timely multi-disciplinary research findings on how flavours in e-cigarettes impacts product appeal (especially to youth), user behaviour (including initiation of product use among non-users and transitions from smoking to vaping among current smokers), chemistry and toxicity of flavoured products, and short/long-term health outcomes
