    Physical characteristics of handmade premium cigars: specifications and consequences of specifications

    TEILLET B.; VERRON T.; COLARD S.
    SEITA-Imperial Tobacco Limited, Fleury-les-Aubrais, France
    Handmade premium cigars consist of natural and heterogeneous leaves rolled by hand to a given dimension. This traditional making process is performed by people (rollers) with considerable experience and training. The rollers adapt their technique,...

    Nicotine reduction: use of a modelling approach to evaluate unintended consequences, a focus on illicit trade

    GUO M.; VERRON T.; CAHOURS X.; COLARD S.
    SEITA-Imperial Tobacco Limited, Fleury-les-Aubrais, France
    In 2015, the WHO TobReg issued an advisory note recommending a strategy of reducing nicotine in tobacco to substantially lower levels. The authors considered that regulation of nicotine levels would lead to a decrease of smoking prevalence. In their...

    Tobacco product comparison: extension of critical difference to account for manufacturing variability

    VERRON T.; CAHOURS X.; COLARD S.
    SEITA-Imperial Tobacco Limited, Fleury-les-Aubrais, France
    In the context of tobacco products comparison, it has been shown previously that the critical difference (ISO 5725) was the best method to consider the variability of testing and laboratories. However as mentioned in several publications, some...
