  1. Key prevalence data, Sweden(Source: ITS/FSI study 2001/2002) MALES FEMALES (n=3205)(n=3507) Daily Daily Daily Daily smoking snus use smoking snus use 15 % 20 % 19 % 2 %

  2. Tobacco consumption per year in Sweden per person 15 years and older Cigarettes Snus (kg) (kg) Around 1920 0.2 1.4 Around 1970 1.1 0.4 Around 2000 0.6 0.9

  3. Swedish snus Fine ground tobacco leaves predominantly from air-cured dark tobacco Manufactured by a pasteurizing-like heating process (without any fermentation so as used in most manufacturing procedures for American snuff) ∎ TSNA content: < 5 mg/kg ∎ BaP content: < 10 g/kg (TSNA content of American snuff: 16-130 mg/kg)

  5. Has the use of snus had an influence on the smoking habits in Sweden?

  6. Initiation of tobacco use: Snus, is it a gate leading to smoking, or a vaccination against smoking? Which is the onset rate of smoking in those who have, respectively have not, taken snus as a primary tobacco use?

  7. ONSET RATE OF DAILY SMOKINGBy presence or absence of primary use of snus All males (n=2756) 40 % With primary snus use (n=397) 20 % Without primary snus use (n=2359) 43 % (Source: ITS/FSI study 2001/2002)

  13. 24 hour systemic intake of nicotineMeasured in: users of loose snus (≈ 2g pinches): around 25 mg(same as in smokers of 18-20 cigarettes per day)Source: Andersson et al 1994, Andersson et al 1997

  17. SUMMARY/CONCLUSIONS (1) In Sweden use of snus is more common than smoking among males but less common among females. Use of snus seems to serve as a substitution for smoking thereby contributing to — less initiation of smoking,— more cessation of smoking. Snus seems to be an effective smoking cessation aid and it is commonly used as such bymales. Use of snus seems not to result in an ”overload” of nicotine. Use of snus produces nicotine dependence but probably less strongly so than smoking.

  18. SUMMARY/CONCLUSIONS (2) Findings from current studies suggest that snus, although not a ”health product” by itself, can, by serving as a substitution for smoking, be one of the many factors that have contributed to the current situation in Sweden with low smoking rates and accordingly low rates of tobacco-related morbidity and mortality..
