Is IQOS better for adult smokers than an e-cigarette?

Both IQOS and e-cigarettes are alternatives to cigarettes, with the potential to reduce risk. However, it is not possible to compare the risks of a specific product (e.g., IQOS) with a product category (e.g., e-cigarettes), which varies widely by individual product. Quantifying the relative risk of a certain e-cigarette product would require data from health outcome studies of its actual usage by smokers. Based on our findings to date, switching completely to IQOS is likely to present less risk of harm than continued smoking* Important Information : IQOS is not risk free * Source: Based on the totality of evidence available for IQOS in comparison with continuing to smoke.
