    Summary

    Cigarette smoking (CS) is the main risk factor for the development and progression of a series of diseases, including cardiovascular disease (CVD) and chronic obstructive pulmonary disease (COPD). Suitable animal models play an important role in understanding of smoke-induced pathogenesis. This study examined the development of hallmarks of both COPD and CVD in Apoe-/- mice exposed to either CS or to an aerosol from a candidate modified risk tobacco product, the tobacco heating system (THS2.2) over an 8-month period. In addition to chronic exposure regimes, a comparison of exposure cessation or switching to THS2.2 after 2 months of exposure to CS was performed using a battery of assays (physiological, morphological and molecular). Biological interpretation of various endpoints enables to understand the biological effects of cessation/switching as compared to continuous smoking.

    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.
