Research on Tobacco Heating System (THS) 1
Research on tobacco heating system THS is progressing rapidly, with reduced risks compared to smoking.

Our research on the latest smoke-free alternative product, Tobacco Heating System (THS) 1, is rapidly advancing. They support the following investigation results (based on expected usage):

 

THS does not produce combustion or smoke. According to laboratory tests, harmful and potentially harmful constituents (HPHCs) in THS aerosol are, on average, 95% lower in toxicity than cigarette smoke. Indoor air quality tests also show that THS aerosol does not have an adverse impact on indoor air quality and it is not a source of second-hand smoke. A 90-day study conducted in the US and a 90-day study conducted in Japan reported that adult smokers who switched exclusively to THS significantly reduced their exposure to selected HPHCs (based on measures of biomarkers of exposure). The level of reduction in biomarkers of exposure was comparable to that of smokers who quit during the study period. Of course, the best option is always to quit smoking and nicotine altogether. Clinical results from a 6-month biomarkers of potential harm study suggest that switching exclusively to THS may have a positive impact on the health of adult smokers. Our research indicates that non-smokers or former smokers have little interest in THS. 70% of adult smokers who switch to THS use it exclusively or in combination with other smokeless products. Teeth staining from THS aerosol is significantly lower than that of cigarette smoke. To date, all of our studies indicate that THS poses a smaller risk of harm compared to adult smokers who exclusively switch to it, although there may still be some risk.
