Summary
Brief summary (as posted)
This study aims to assess the feasibility, acceptability, and the potential harm reduction of switching to potentially lower risk, oral nicotine pouches in adult smokers. Part One of this study aims to assess the interest of current smokers in switching to an e-cigarette device (i.e. JUUL) compared to alternative non-combustible tobacco products (i.e. smokeless tobacco/snus) and/or medicinal nicotine via survey. Part Two will consist of a pilot study of 30 non-treatment seeking adult smokers to investigate within-person changes in smoking behavior as a result of switching to different concentrations of oral nicotine pouch products (i.e. ZYN, 3mg and 6mg nicotine concentration). Additionally, by measuring bio-markers of tobacco exposure from baseline, this will allow the study to assess the potential for harm reduction in switching from cigarettes to oral nicotine pouches.
