While the idea of heating tobacco, instead of burning it, has been around for more than two decades, it's only now that we have managed to find a way to heat tobacco that results in a product that is satisfying to adult smokers. Around three million consumers have already chosen to switch from cigarettes to our tobacco heating system - IQOS.IQOS is a sophisticated electronic device specially designed to heat tobacco. IQOS heats the tobacco just enough to release a flavorful nicotine-containing vapor but without burning the tobacco.
