Comparison of the 1C2 Reference Filtered Cigar to the 1R6F Reference Filtered Cigarette

This study indicates that, if compared by filler weight, the 1C2 reference filtered cigar is more toxic than the 1R6F reference cigarette. Since these products were manufactured based on commercial products and at least some consumers of filtered cigars inhale smoke from these products into the lung, this suggests that some filtered cigars will be at least as harmful to consumers as conventional cigarettes.
