Philip Morris International is developing products with the potential to reduce the risk associated with smoking. The Tobacco Heating System (THS 2.2) operates by heating tobacco rather than burning it and results in an aerosol with substantially lower levels of harmful or potentially harmful constituents when compared to combustible cigarettes (CC) smoke. Additionally, THS 2.2 does not produce sidestream aerosol in the same manner as CC, since aerosol is only generate when puffs are taken. Thus, the impact on air quality of using THS 2.2 indoors is expected to be very different to CC. To verify this hypothesis, we built an environmentally controlled, furnished room and developed analytical methods to measure air pollutants under diverse simulated indoor environments focusing on: (i) ISO measurement standards for Environmental Tobacco Smoke and, (ii) selected carbonyls and volatile organic compounds.
A study was conducted with 3 simulate conditions (office, hospitality, residential) with conditions defined according to CEN standard EN 15251.2007. Three test items were compared: CC (Marlboro Gold 6mg), THS 2.2 and background (measured with people in the room without product use). Each study was duplicated, resulting in 18 separate session in total, each with a duration of 5 hours, with 4 hours of sample collection.
In case of statistical equivalence, no impact on air quality is reported. For CC, all analytes for the 3 conditions were above background. For THS 2.2, no difference was detected between background and THS 2.2 for 15 of the eighteen analytes investigated, irrespective of the environment conditions applied.
