Variations in Nicotine Yields between Single Cigarettes

Abstract

Introduction and Aims: It is beyond any doubt that nicotine yield in cigarettes as determined using standard ISO method bears almost no relation to smokers' actual intake. However, the ISO method is still in use in many countries where the government is responsible for controlling and monitoring cigarette quality. The aim of the study was to measure the nicotine yield in single cigarettes and to evaluate their statistical distribution among the same brand. Materials and methods: Nicotine yields were measured according to the ISO method in single cigarettes of the twenty most popular Polish brands of cigarettes. Results: Relative standard deviation of nicotine yields in single cigarettes of the same brands varied from 16% to 34%. Relative differences between nicotine yields in a single cigarette of a particular brand and the mean value varied from −65% to +76%. Discussion and Conclusions: The results indicate high variation in nicotine yields between cigarettes of the same brand. Such variation might affect compensatory smoking. This provides another reason why yields estimated using the standard ISO method are potentially misleading to smokers. Further studies are needed to better understand the implications of within-brand variability in yields for tobacco product regulation.

E‐cigarettes: voltage‐ and concentration‐dependent loss in human lung adenocarcinoma viability

“…For tobacco smoke, a conservative approach used Cambridge filters to collect particulate matter (Goniewicz et al, ; Health Canada, ) and then eluted with organic solvents to generate particulate matter solution, which may be added to the cell cultures (Misra, Leverette, Hamm, & Vulimiri, ). Water‐soluble CS components from both particulate and vapor phases can be captured in impingers containing growth media (Bernhard et al, ; Cantrall, Sisson, Veys, Rennard, & Spurzem, ).…”

Analysis of electronic cigarette use among Polish dental students

“…Research conducted by Eissenberg,19 as well as the findings of Vansickel et al 20 showed that e-smoking results in a lower nicotine concentration in the blood circulation system, in comparison to traditional smoking. Interesting results have also been presented by Goniewicz et al 21,22 Their studies focused on the nicotine concentration in aerosols, as well as on the quantity of nicotine being delivered to the human body while smoking a single traditional cigarette with a determined nicotine amount.…”
