Tobacco constituent extraction from snus during consumer use
Date:4/1/2013

obacco products (STPs) pose varying levels of risk to their users in line with their toxicant content. However, the findings from this research show that the toxicant content of STPs may not reflect what is actually ingested by consumers.

The results provide reference data for the development of a laboratory system that mimics the real-life extraction of tobacco constituents from snus. Such a system would be a cheaper and more efficient alternative to human studies.

In addition, the results show that exposure to snus constituents by consumers is a variable process. The researchers suggest that uptake may be affected by composition and amount of saliva, pressure and movement applied to the pouch during use, and different physiological characteristics of participants.

The next step is to apply the multi-analyte approach to different types of snus, in order to understand the effects of, for example, pouch size and water content. Further work is also needed to understand the importance of usage time, solubility of constituents in saliva, and real-life factors like consuming beverages or food while using snus.
