Abstract
Introduction and Aims: In Australia, tobacco smoking rates are significantly higher among low socio-economic status populations [1]. This study evaluates the effectiveness, safety and cost-effectiveness of vaporised nicotine products (VNP) compared with nicotine replacement therapy (NRT) for smoking cessation among low socio-economic status Australian smokers.
Design and Methods: This is a two-arm, open-label, randomised controlled trial conducted at the National Drug and Alcohol Research Centre, UNSW Sydney, Australia. Participants are people who smoke daily, are interested in quitting and receive a government pension (N = 1058). Participants will be randomised (1:1 ratio) to free: 8 weeks of VNPs (pod [40 mg/mL nicotine salt] and tank device [18 mg/mL freebase nicotine] in mixed flavours) or 8 weeks of NRT (gum or lozenge; 4 mg). Participants receive daily text message behavioural support for 5 weeks. Assessments are undertaken at baseline, two check-in calls within first month and final follow-up at 7 months to ascertain smoking status, treatment adherence and adverse events. The primary outcome is six-month continuous abstinence verified by carbon monoxide breath test of ≤5 ppm at seven-month follow-up. Safety and cost-effectiveness of VNPs versus NRT will also be evaluated.
Results: Research in progress, results unavailable at time of submission.
Discussions and Conclusions: Further data are required to strengthen certainty of evidence for VNPs aiding smoking cessation, particularly for newer generation pod devices. To our knowledge, this trial is the first to offer choice of VNPs and no comparative effectiveness trial data exists for new pod devices.
Implications for Practice or Policy: If effective, the findings can inform wider implementation of VNPs to aid smoking cessation in a priority group.
