IQOS is potentially less harmful than cigarettes. Aerosol generated by IQOS has got a lower concentration of toxins and emits an average of 90-95% lower levels of harmful and potentially harmful compounds compared to cigarette smoke with the similar level of nicotine. This is a real revolution! IQOS offers additional benefits such as no smoke, no ash, and less smell. Aerosol present while using IQOS escapes faster than cigarette smoke. Using IQOS is simple, efficient and satisfying. It uses an electric heat source to heat tobacco at precisely controlled temperatures below combustion levels. This tobacco heating system is used with specific tobacco sticks called HEETS or HeatSticks. The Heatsticks themselves are a highly engineered product, with a proprietary blend of tobacco/flavorings/excipients that produce a vapor when heated.
