Below, we’ve listed the levels of those HPHCs (with the exception of nicotine) measured in the smoke of a standard reference cigarette (3R4F) and the aerosols of two versions of our Tobacco Heating System (THS 2.2), the THS 2.2 Regular and the THS 2.2 Smooth Menthol. In all cases where a comparison could be made, we found that HPHC levels in the THS were lower compared to 3R4F, with an average reduction of more than 90.5% on a stick basis for THS 2.2 Regular and more than 91.0% on a stick basis for THS 2.2 Smooth Menthol.
The reductions in this table are fully in line with the one previously calculated using the PMI-58 list. The similarity of the results between the THS regular and THS menthol also show that the reduction in levels of HPHCs is related to the heat-not-burn principle and not impacted by the nature of the flavor system.
Here are the levels of HPHCs, as well as standard deviation (SD), for the THS 2.2 Regular and THS 2.2 Smooth Menthol, compared to 3R4F. The number of replicates for each analyte is 3. All analyses were conducted by Labstat International ULC (Kitchener, ON, Canada), an independent laboratory, according to their own methods and protocols. The standard Health Canada Intense smoking regime was applied to both the 3R4F and the THS.
