      PMI Science: Transparency and Scientific Rigor Behind PMI's Smoke-Free Products

      At PMI Science, our aim is to decrease the impact smoking has on public health, which is the essence of tobacco harm reduction. We do this by developing and assessing better alternatives to cigarette smoking–alternatives that don't burn tobacco–following rigorous scientific methods.

      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.
