BACKGROUND: Smoking is Australia's leading preventable cause of premature mortality and a major contributor to the national disease burden. If quit rates do not dramatically improve, then smoking will continue to be a major public health issue for decades to come. Harm-reduction approaches using novel nicotine products like e-cigarettes as long term replacements for smoking have the potential to improve quit rates. However, little research has assessed such approaches. METHODS/DESIGN: DESIGN: Three-arm parallel-group pragmatic randomised controlled trial. PARTICIPANTS: People living in Australia who are at least 18 years old, smoke five or more cigarettes per day and are willing to try a sample of nicotine products. INTERVENTION: Participants are randomised to receive standard quit advice and medicinal nicotine (Condition A); quit or substitute advice and medicinal nicotine (Condition B); or quit or substitute advice and medicinal nicotine and e-cigarettes (Condition C). Participants choose which (if any) nicotine products to receive to try in a free sample pack followed by a two to three week free supply of their favourite product(s) and the option to purchase more at a discounted price. Follow-up surveys will assess nicotine product use and smoking. PRIMARY OUTCOME: Continuous abstinence for at least 6 months. Target sample size: 1600 people (Condition A: 340; Condition B: 630; Condition C: 630) provides at least 80 % power at p = 0.05 to detect a 5 % difference in abstinence rates between each condition. DISCUSSION: This trial will provide data on tobacco harm-reduction approaches and in particular the use of e-cigarettes as a replacement for smoking.
