    A review of the incidence and consequences of cigarette filter vent blocking among smokers

    British American Tobacco, R&D Centre, Southampton, UK
    Vent blocking, the covering of the filter ventilation zone on a cigarette during smoking, is a potentially important aspect of smoking behavior. Various techniques have been used to assess the incidence of vent blocking, and widely different views have ...
