Table 2 Relative toxicity emissions scores for Marlboro Ultrasmooth and selected conventional brands. Standardised against British Columbian regular brands, in ISO and HCI test modes, with and without adjustment for nicotine yield.

Brand	Test year	Test mode	Nicotine yield (SD) mg	Toxicity of emissions relative to those of 16 BC regular brands weighted by each disease group's attributable mortality			RTE score, all disease groups
