Key Points

The aim is to compare the toxicity of the 1C2 filtered cigar to the 1R6F filtered cigarette based on filler weight.
Comparison of toxicity based on filler weight
Analysis of consumer inhalation patterns
Manufactured products based on commercial versions
1C2 filtered cigar identified as more toxic than 1R6F filtered cigarette
Implication that some filtered cigars are as harmful as conventional cigarettes

Abstract

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.
