Associations between the use of Swedish snus (moist tobacco) and changes in smoking behaviour

Population:

Smokers, any age, men and women

Exposure:

Self-reported current or ever use of snus, with or without nicotine

Comparison:

No self-reported use of snus, with or without nicotine, all through the study period

Outcomes:

Self-reported non-use, non-use for at least 30 days, increased use or decreased use of combustible tobacco products at follow up

What evidence is needed?

More primary research is needed.

• There is a need for primary studies investigating associations between the use of snus (moist tobacco) and current use of cigarettes. Since the tobacco market and the use of tobacco has changed during the last decade, it is important to investigate associations in contemporary populations.
• The development and implementation of validated instruments aimed to assess those at risk for future use of tobacco, could also make it possible to obtain analysis of associations in groups with different risks and risk behaviours.
• More standardised definitions of both exposures and outcomes are needed to increase the benefits of future research in this field. Furthermore, there is also a need for studies collecting and reporting data regarding the levels of exposures and outcomes, since it would increase the possibilities to investigate associations between different degrees of exposures and outcomes.
