A recent study, recommends that environmental tobacco smoke (ETS)-associated particulate matter (PM) has to be seen as an independent health hazard. The authors suggest that "brand-specific amounts of PM are of public interest and should be investigated".
The authors show in a "modified ToPIQ-II study protocol" significant brand-specific differences in the amounts of PM2.5 released by cigarettes into the environment. They suggest to publish information about PM-release of different brands "in the light of PM as an independent risk factor for morbidity and mortality" as a basis for further epidemiologic investigations.
