<abstract xmlns="http://www.w3.org/1999/xhtml"><p>Filter analysis methodology can be used to estimate smokers’ mouth level exposure (MLE) to ‘tar’ and nicotine from spent cigarette filters. Variation in smoking behaviour and cigarette design are known to have an impact on the range of ‘tar’ and nicotine MLE. Most ‘King Size’ (KS) cigarettes have a circumference of about 25 mm and are 83-84 mm long, with filters 20-27 mm in length. Recently, a slimmer format, described as a ‘King Size Superslim’ (KSSS), with a circumference of 17 mm, has become popular in several countries. Although several studies have estimated the MLE to ‘tar’ and nicotine of smokers of KS cigarettes, there have been no studies of KSSS smokers reported to date. KSSS cigarettes from Romania were chosen for this study with a single product to represent each 1, 4 and 7 mg machine-smoked ISO ‘tar’ yields. Since these products have filters containing activated carbon, comparisons were made with a single product at each ISO ‘tar’ level of KS cigarettes with both activated carbon filters (King Size Carbon - KSC), to assess the effect of format on MLE, and cellulose acetate filters (King Size Non-carbon - KSNC) to assess the effect of filter carbon on MLE. A target population of 50 to 70 male and female smokers (subjects) aged 21 to 50 years of each product were recruited in Romania, with self-reported consumption of 15-25 cigarettes per day.

Regarding MLE to ‘tar’, there were no significant differences between the KSC, KSNC and KSSS smokers within each of the 1, 4 and 7 mg machine-smoked ISO ‘tar’ yield groups, but there were significant differences between the ISO pack ‘tar’ groups: 1 mg &lt; 4 mg &lt; 7 mg. Regarding MLE to nicotine, KSC and KSSS smokers obtained similar yields within an ISO pack ‘tar’ group. KSNC smokers obtained lower MLE nicotine yields than the KSC and KSSS smokers at both 4 mg and 7 mg ISO pack ‘tar’, corresponding to lower blend nicotine levels.
