The main cause of smoking-related diseases is the smoke produced by burning cigarettes. Tobacco on the tip of the cigarette burns under the influence of high temperatures, producing a large amount of smoke containing harmful substances.
Unlike cigarettes, IQOS heats tobacco to a much lower temperature. This is where the main differences between burning a cigarette and heating tobacco come from.
IQOS aerosol contains significantly less harmful substances than cigarette smoke. More specifically, IQOS aerosol contains on average 95% less harmful substances than cigarette smoke. 1
One of the most dangerous substances in cigarette smoke is carbon monoxide, which is produced in large quantities as a result of cigarette combustion. Unlike cigarettes, IQOS produces on average 98% less carbon monoxide.2
Studies have shown that IQOS does not have a negative impact on air quality 3 due to the absence of combustion or cigarette smoke. IQOS poses less of a health risk to you and your loved ones than continuing to smoke.
IQOS has extensive and robust clinical evidence showing that using IQOS presents less risk to your health than continuing to smoke.4
1Reductions in levels of a range of harmful chemicals (excluding nicotine) compared to the smoke of a reference cigarette.
2Important information: This does not mean at 98% reduction in risk. IQOS is not risk free, and delivers nicotine which is addictive.Source: We measured the levels of certain harmful chemicals prioritized for reporting by renowned public health organizations, and these are reduced on average by 95% compared to the smoke of a cigarette (nicotine excluded).
