Tobacco manufacturers have recently introduced a proliferation of exotic brands featuring candylike flavors. We reviewed internal tobacco industry documents and patents to assess the role of flavored cigarettes in the targeting of young smokers. This research revealed the development of flavor delivery technologies hidden from consumers and public health professionals, including the use of a plastic pellet placed in the cigarette filter. These findings raise concerns as to the potential added health risks associated with using new flavored tobacco products, and they underscore the need for effective assessment and monitoring of tobacco products.
