Abstract

Smokeless tobacco is used in all Scandinavian countries. By far the highest consumption is recorded in Sweden, where the highest sales figures in the world can be found. Moist non-fermented snuff with a pH value of 8–9 comprises over 99% of the products. Only a few tons per year of chewing tobacco are sold. Moist snuff as it is used in Scandinavia today gives rise to oral mucosal changes which are reversible after cessation of the habit. The use of portion-bags, and even more so the use of chewing tobacco, seems to be associated with less pronounced changes than the use of loose snuff. The daily amount of snuff used and hours of daily use seem to have a greater impact on the risk for development of more pronounced changes as recorded clinically and histologically than the number of years with the habit and/or age of the subject. Gingival recessions are much more frequently found among users of loose snuff than among users of portion-bag-packed snuff and they seem to be irreversible.

      Acanthosis and slight inflammation may also be present accompanied by an increased mitotic rate (Larsson et al., 1991). It should be distinguished from smoking induced preneoplastic forms of leucoplakia displaying cellular atypia/dysplasia (Axéll, 1993; Axéll et al., 1976; Andersson and Axéll, 1989). These dysplastic lesions are typically induced by betel chewing, or by other impure tobacco products used in South East Asia and Sudan (Zain et al., 1997).

      In former years a pinch (or dip) was placed between the gum and upper lip, often for 11–14 h daily (International Agency for Research on Cancer, 2007a), but more recently the most common method of application by far is by portion-packed tobacco in small sachets. This change follows studies showing that use of pack products greatly reduces the risk of tobacco-related oral pathological changes (Andersson and Axéll, 1989; Axéll, 1993). Use of snus involves nicotine exposure similar to, and perhaps somewhat greater than, that from smoking (Agewall et al., 2002; Bolinder et al., 1997a,b; Bolinder and de Faire, 1998; Eliasson et al., 1991; Holm et al., 1992; Wennmalm et al., 1991).

      Smokeless tobacco (ST) in the modes of chewing tobacco and snuff is used in a large number of variations worldwide. ST habits have been extensively described from South- and Southeast Asia as the betel quid chewing habit1 and as snuff dipping or snus from the USA and Scandinavia.2,3 While there is also increasing information on similar habits from Northern Africa,4–13 the use of ST in the Arabian peninsula has less well been studied and reported.14–23
