Objective: The World Health Organization (WHO) Framework Convention on Tobacco Control (FCTC) reported that understanding the use and impact of smokeless tobacco (SLT) products is complicated by product diversity. Many different SLT products with different characteristics are used worldwide. ZERO STYLE STIXTM (sold by Japan Tobacco Inc.) is a brand of snuff, a type of smokeless tobacco. Our objective was to determine the constituents of the gas from SLT and analyze the ingredients in tobacco fillers. Methods: ZERO STYLE STIX smokeless tobacco was released in the Japanese market in 2010. Nicotine, menthol, and tobacco-specific nitrosamines in the smokeless tobacco fillers were determined by gas chromatography-mass spectrometry (GC/MS) and liquid chromatography-tandem mass spectrometry (LC/MS/MS). The gaseous compounds were collected by a smoking machine using two smoking protocols, i.e., the ISO and Health Canada Intense methods. Nicotine and menthol in the gas were determined by GC/MS. Results: Nicotine, menthol, and the total tobacco-specific nitrosamines were detected in the tobacco fillers. The level of menthol in the snuff was more than ten times that of nicotine. The determined levels of the two components of the gas from the snuff were higher when using the Health Canada Intense protocol than when using the ISO protocol. In addition, flavors other than menthol were emitted from the smokeless tobacco. Conclusion: The new type of snuff introduced in the Japanese market in 2010 contained added flavors, and was attractive smokeless tobacco. Flavors in tobacco products need to regulate on the basis of FCTC 9 and 10 in JAPAN.
