摘要

Modern oral nicotine delivery (MOND) offers potentially reduced harm nicotine delivery for adult smokers who do not wish to quit. Most clinical studies to date have characterised MOND with lower nicotine content, therefore, this study aimed to assess products with higher nicotine strengths. This randomised, open-label, cross-over, confinement study, conducted in Sweden, compared the nicotine pharmacokinetic and subjective effects of three MOND products, zoneX #5 slim (14 mg nicotine/pouch), zoneX #5 (16 mg) and zoneX #6 (20 mg), and a tobacco snus product (Skruf Slim Fresh #5 (16.6 mg)) in 27 adult snus or MOND users. The zoneX #6 product delivered the highest levels of nicotine; however, all products exhibited similar reductions in urge to use nicotine during and following a controlled product use session. Furthermore, the zoneX products generally scored more favourably than the snus on a 7-point Likert product evaluation scale for satisfaction, psychological reward, aversion and relief, assessed 8 h after the start of product use. There was some indication that pouch size may influence nicotine uptake, however, further characterisation is required. All study products demonstrated good short-term tolerability, with no serious adverse events observed. Overall, the findings support that MOND has tobacco harm reduction potential, providing a satisfactory alternative for adult smokers.
