Manipulating Tobacco Constituents in Male Menthol Smokers

The FDA has the regulatory authority to reduce, but not eliminate, nicotine from cigarettes.
The Tobacco Products Scientific Advisory Committee has noted, among other things, that
removal of menthol cigarettes from the marketplace would benefit the public health. A parent
study (NCT02048852) examines the potential impact of these two regulatory actions alone and
in combination in female menthol smokers. This supplemental study will recruit an additional
group of male menthol smokers, which will examine whether there are gender differences in
manipulating flavors and nicotine concentrations in cigarettes on smoking behavior. The
approach to add the opposite sex allows findings of sex/gender to be incorporated in the
design and development of new technologies (i.e., modified cigarettes). Emerging research
shows that women may be more responsive to the non-nicotine sensory aspects of smoking such
as menthol flavor, whereas men may smoke primarily for nicotine intake. Consequently, this
study expects to observe gender differences in response to manipulating flavors and nicotine
content in cigarettes.
