Barts and The London School of Medicine and Dentistry, of the Queen Mary University of London, have announced they will soon begin a new study investigating the habits of people who dual use electronic and combustible cigarettes. The study will monitor up to 500 dual users, in the hope that it can gain a greater understanding of an often-neglected area of smoking cessation research:

Most dual users aim to stop smoking altogether, but many people continue using both products. It is not clear at present how many of these dual users stop smoking, at which time point, and what factors help them to stop.

The researchers have laid out the following conditions:

  • Participants must be 18 or over, currently using both an e-cigarette and combustible cigarettes.
  • This use must occur on the same or separate days, for at least one day a week,
  • Participants will be asked questions about their vaping and smoking over the telephone or internet at 3-month intervals, over a 12-month period.
  • The surveys should take approximately 10 minutes each to complete. You will receive a £15 voucher as compensation for your time.

UoL would like to assure participants that their role is completely voluntary, that they are free to drop out at any time, and that their data and privacy will be respected at all times. Participation will also have no effect on any medical treatment or services you are currently receiving.

Should UoL hit their funding goals, they will be able to extend the study’s follow-up period from one year to ten.

How exactly will the study play out? Baseline involvement via phone call and email will be as follows:

“If you are interested in taking part in this study, we will check that you are eligible and email you a web-link to provide your consent to take part and to complete the initial questionnaire online.
If you do not have internet access, we will ask you the eligibility questions over the phone and will post a consent form to you, along with a paper version of the baseline questionnaire. You would then be asked to return these completed documents back to us using a self-addressed envelope provided. You will receive a £5 voucher for completing the first questionnaire.”

The three, six, nine and 12-month follow-ups will come with an extra boon.

“We will send you another questionnaire to complete by email or post. You will receive a £5 voucher for completing the questionnaires at 6 and 12 months.”

Vapers and the businesses we support always benefit from having a larger body of research out there in the public eye. Many studies published in recent years have not only better informed us about the habits and health of e-cigarette users, but better equipped us to make the case for vaping as a safer, effective and underrepresented tool for smoking cessation to our elected officials and advocacy groups. Most of us are former smokers who underwent a period of dual use. Adding to the limited body of knowledge on this transitional period of nicotine replacement is invaluable.
