In an attempt to gain some insight into the range of toxicant yields of current commercially available cigarette products, we measured the toxicant emissions from a wide range of products over a number of years. The database currently consists of ISO smoke yields for 959 products, 364 for HCI smoke yields sourced from 80 geographical areas, and 916 blend chemistries (Supplementary Fig. 1).
The British American Tobacco (BAT) dataset includes cigarette products from a number of international and national manufacturers, and includes a range of cigarette formats (circumference, length, and filter type) and blend styles (flue-cured Virginia, US-blended, and blends disposed between these two styles). The database was assembled over the time period between 2007 and 2011. This dataset is of sufficient size to enable comparison of smoke emissions from different products and to characterise differences in smoke chemistry between many countries.
