As the addition of the clove preparations increased TPM and tar yields in a similar way, a comparison of the deliveries of MS toxicants on a per mg tar basis leads to the same findings as to those expressed on a per mg TPM basis. In the same way, the comparison on a per mg nicotine basis is equivalent to a comparison on a per cigarette basis, as the nicotine yields per cigarette were virtually the same for all cigarette types. However, in contrast to the TPM-based evaluation, a comparison on a per mg nicotine basis showed either equal deliveries, e.g., aldehydes and NOx, or increased deliveries, e.g., PAHs and phenols. The increases were nearly all statistically significant (Fig. 2).The TPM yields of the reference cigarette 2R4F and US cigarettes or the cigarette US-C are too different to allow a meaningful comparison of their smoke toxicants deliveries on a per cigarette basis when assessing the effects of clove preparations on American-blended cigarettes. However, the comparison of the cigarette IND-C with Indonesian tobacco with the American-blended cigarette US-C, both with the addition of full cloves, shows roughly the same TPM and smoke toxicant deliveries per cigarette. Exceptions are a few distinct tobacco blend-related differences, as in the IND-C lower nitrogen containing toxicants such as 2-nitropropane, NOx, and TSNAs and higher phenolics, and PAHs in the Indonesian-blended cigarette (Appendix, Table A). On a per mg TPM basis, the differences were the same as on a per cigarette basis (Fig. 4). The comparison of the American-blended reference cigarette 2R4F without cloves with the cigarette US-C with full cloves on a per mg TPM basis reveals similar decreases in the yields of MS toxicants as seen for the Indonesian-blended cigarettes due to the addition of cloves and its components. As in the Indonesian-blended cigarettes, the deliveries of TSNAs were not decreased compared to a non-clove cigarette. The comparisons performed on a per mg tar or nicotine basis lead to the same conclusions for the American-blended cigarettes as those derived for the Indonesian-blended cigarettes.
