This is why I find it so troubling that some major voices in the e-cigarette community are arguing that RCTs should not be conducted and only survey studies are of value.

This lack of transparency in the report is unfortunate because readers deserve to be informed about financial conflicts of interest that could potentially have influenced the report's presentation and interpretation of the scientific evidence. This is especially important because the report makes broad conclusions regarding national strategies for smoking cessation. Thus, if the report's authors have received money from pharmaceutical companies that make the very products about which the report is opining, it would be critical to disclose these conflicts. The report fails to do so.

In fact, the bulk of the evidence suggests that the introduction of the cigarette filter, while obviously not making cigarettes substantially safer, did result in small but measurable declines in cancer risk. These declines occurred due to a tremendous reduction in tar yield, from levels as high as 40-50 mg down to less than 20 mg. The evidence suggests that further declines - to levels below this massive initial drop - were not associated with further declines in cancer risk.
