    Smoke-free approach

    Our mission

    In 2016, Philip Morris International (PMI) announced our vision of a smoke-free future and our ambition to accelerate the end of smoking. To achieve this, we are working to replace cigarettes with less harmful tobacco and nicotine products for the benefit of adults who would otherwise continue to smoke.

    Science-Driven Policies: The Key to Better Outcomes

    Taking place on April 10, 2025, at 4:00 p.m. CEST, our next event will be broadcast on our Open Science platform, LinkedIn®, and Philip Morris International’s (PMI’s) YouTube channel. In this prerecorded event, our panel of experts will explore the current state of tobacco control policies and the role of science and research in crafting informed and effective strategies to address the need to reduce smoking rates globally. They’ll also discuss the role of nicotine in effective tobacco harm reduction strategies. Don’t miss the opportunity to watch this informative session.

    PRODUCT TECHNOLOGIES

    Our smoke-free products

    Smoke-free products is the term Philip Morris International (PMI) uses to refer to products that provide nicotine without burning tobacco. These products deliver nicotine and far lower quantities of harmful and potentially harmful constituents compared with cigarette smoke. Because no combustion takes place, smoke-free products have the potential to present less risk of harm to adult smokers who switch to them versus continuing to smoke.

    Reduced Risk Products ("RRPs”) is the term we use to refer to products that present, are likely to present, or have the potential to present less risk of harm to smokers who switch to these products versus continuing smoking. PMI has a range of RRPs in various stages of development, scientific assessment and commercialization. All of our RRPs are smoke-free products that deliver nicotine with far lower quantities of harmful and potentially harmful constituents than found in cigarette smoke.
