► Stratified market allows view of entire market with small sampling. ► Smoking with the Health Canada smoking regimen maintains “tar” category rankings. ► Normalization by nicotine reverses rank ordering. ► Mostly, non-menthol and menthol cigarette yields were not significantly different. A survey of selected mainstream smoke constituents from commercially marketed US cigarettes was conducted in 2009. The US cigarette market was segmented into thirteen (13) strata based on Cambridge Filter Method (CFM) “tar” category and cigarette design parameters. Menthol and non-menthol cigarettes were included. Sixty-one (61) cigarette brand styles were chosen to represent the market. Another thirty-four (34) brand styles of interest were included in the survey along with a Kentucky 3R4F reference cigarette. Twenty mainstream smoke constituents were evaluated using the Health Canada smoking regimen. By weighting the results of the 61 brand styles using the number of brand styles represented by each stratum, the mainstream smoke constituent means and medians of the US cigarette market were estimated. For nicotine, catechol, hydroquinone, benzo(a)pyrene and formaldehyde the mean yields increased with increasing “tar” yields. Constituent yields for the ultra-low “tar” and low “tar” cigarettes were not significantly different for most other analytes as ventilation blocking defeated any filter air dilution design features. In contrast, normalization per mg nicotine provided an inverse ranking of cigarette yields per CFM “tar” categories. Menthol cigarette mean constituent yields were observed to be within the range of the non-menthol cigarettes of similar “tar” categories.
