What is heat-not-burn?

Key Publications


“This research is very personal to me.”

Philip Morris International (PMI) is developing a range of new products with the objective of offering adult smokers a less harmful alternative to continued cigarette smoking. PMI has a rigorous and extensive program designed to assess each product’s potential for reducing harm compared to continued cigarette smoking. The program follows established scientific precedents and draft guidance for Modified Risk Tobacco Product Applications (MRTPA). The scientific assessment standards and methods are similar to those used by the pharmaceutical industry, including product design controls, a range of toxicological tests, clinical studies, premarket consumer perception and behavior studies, and planned postmarket assessments.
