The Pulze HTS, which comprises the Pulze HTP device and iD sticks, generates a nicotine-containing aerosol by heating consumable sticks containing reconstituted tobacco using an electrically powered heating device as its heating source. This heating creates an inhalable aerosol to deliver nicotine via the lungs. The device can be operated in two different user-selected modes (‘standard’ and ‘eco’ modes) in which the device heats to temperatures of 345 °C and 315 °C, respectively. In this study, subjects only used the Pulze HTP in ‘standard’ mode. Once switched on the Pulze HTS device is operational for 4 min, which allows users to take approximately 8–9 puffs from a single iD stick.The tobacco sticks contain a portion of reconstituted tobacco and other non-tobacco components. Three test iD consumables (reconstituted tobacco sticks used with the Pulze HTS device) were assessed in this study; Intense American Blend, Regular American Blend, and Regular Menthol. The aerosol from the Intense and Regular American Blend sticks has a tobacco aroma, while the aerosol from the Regular Menthol sticks has a menthol aroma due to the inclusion of a menthol-flavoured monoacetate filter at the mouth-end of the stick. The reconstituted tobacco in each of the Pulze iD consumables used in this study has a target specification of 4.6 mg of nicotine per stick, and different aerosol yields of nicotine are achieved by the use of different filters in each of the different iD consumables. When used under International Organization for Standardization (ISO) intense machine puffing conditions (55 ml bell-shaped puff over 2 s with a 30-s interpuff interval and with filter vents blocked)For use as a comparator product, all subjects provided their usual brand of cigarette.
