    Nicotine pharmacokinetics and subjective effects of novel heated tobacco product compared to cigarettes: a randomised, crossover study

    YUKI D.*; GILES L.; HARBO S.; HEMSLEY A.
    JT International SA, Scientific & Regulatory Affairs, Geneva, Switzerland (* Now at Japan Tobacco Inc., Scientific & Regulatory Affairs, Tokyo, Japan)
    The nicotine pharmacokinetics (PK) and subjective effects of non-combustible tobacco products, including heated tobacco products, have been widely assessed, with a lower or similar nicotine exposure noted for many products when compared to...

    Characterization of nicotine pharmacokinetics from use of a novel heated tobacco capsule prototype in adults who smoke

    EDMISTON J.; LIU J.; WANG J.; LAU R.; PITHAWALLA Y.B.
    Altria Client Services LLC, Center for Research and Technology, Richmond, VA, U.S.A.
    Heated tobacco products (HTPs) may offer a potentially reduced-risk alternative to adults 21+ who smoke cigarettes (AS) and are unable or unwilling to quit. In this study, we characterized the nicotine pharmacokinetics (PK) and subjective measures of...

    Monitoring puff-by-puff aerosol generation and delivery when vaping viscous liquids by using in-line pressure drop measurement

    TAYLOR H.; TINDALL I.F.
    Cerulean, Milton Keynes, U.K.
    Vape devices containing highly viscous liquids can be problematic in delivering a consistent aerosol over the lifetime of a vape experiment due to liquid mobility, with the user potentially being unaware of reduced deliveries. To mitigate this...

    Determination of nicotine, propylene glycol, menthol, glycerol and water by GC-FID & TCD using nitrogen as the carrier gas

    SAKASHITA R.; NANJO K.; OMORI F.
    Japan Tobacco Inc., Scientific Product Assessment Center, Yokohama, Kanagawa 227-8512, Japan
    The CORESTA E-Vapour Sub-Group has developed a Recommended Method No. 84 (CRM 84) for nicotine, propylene glycol, glycerol and water in e-vapour aerosols by gas chromatography (GC). We also have developed an analytical method for those components in...

    Simultaneous multisensor physical characterisation of heated tobacco product aerosol and the selection of a reference system

    TINDALL I.F.; REDDY S.; LAIMON H.
    Cerulean, Milton Keynes, U.K.
    As a measurement of consistent aerosol delivery, simultaneous multi-sensor analysis of physical characteristics of electrically heated tobacco product (eHTP) aerosol reveals the inherent difficulties of utilising commercially available, or specially...
