This study is approved by the National Research Ethics Committee West Midlands.

Thank you for your interest in this new study looking to follow-up people who both smoke and vape (i.e. 'dual users'), to learn about how this use develops and what proportion of nicotine such ‘dual users’ get from vaping and from smoking over time. This study is the first of its kind, and your participation could make a difference to our understanding of e-cigarettes and their use.

The study is run by the Health and Lifestyle Research Unit at the Wolfson Institute of Preventive Medicine, Queen Mary University of London, a world leader in this field. If you decide to take part, we will ask you to complete some questionnaires over the phone and provide a saliva sample by post at baseline and again at 3 and 6 and 12 months.

In addition to this, if you are interested in receiving help to stop smoking altogether, we will provide you with stop-smoking medication and telephone support.
