IQOS is a better alternative to cigarettes. Unlike cigarettes, IQOS does not burn tobacco and therefore produces no smoke. The best choice any smoker can make is to quit cigarettes and nicotine altogether. But for adult smokers who would otherwise continue to smoke or use nicotine containing products, switching completely to IQOS is a better alternative to continued smoking. Important information: IQOS is not risk-free. It delivers nicotine, which is addictive.
