Initial analyses of the novel smokeless tobacco products Camel Snus and Marlboro Snus demonstrated that these products contain relatively low amounts of nicotine and the carcinogenic tobacco-specific nitrosamines N'-nitrosonornicotine (NNN) and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), as compared with traditional smokeless products. It is unknown whether the modifications in packaging, flavors, and pouch sizes that occurred for both Camel Snus and Marlboro Snus since their first introduction to the market were accompanied by any changes in nicotine or nitrosamine levels.
