About this study

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.

Treatment and study plan

Reduced Nicotine Non-Menthol (RNC)

Other

Switch from own brand of cigarette to an investigational tobacco product with a reduced nicotine content of 0.07mg nicotine yield without menthol.

Other names: SPECTRUM Research Cigarette - NRC 200

Reduced Nicotine Menthol (RNC-Men)

Other

Switch from own brand of cigarette to an investigational tobacco product with a reduced nicotine content of 0.07mg nicotine yield with menthol.

Other names: SPECTRUM Research Cigarette - NRC 201

Conventional Nicotine Non-Menthol (CN)

Other

Switch from own brand of cigarette to an investigational tobacco product which contains conventional nicotine yield.

Other names: SPECTRUM Research Cigarette - NRC 600

Primary outcomes

  1. Gender differences and change in number of investigational tobacco product(s) smoked per day as assessed by the Timeline Follow-Back (TLFB)

    Time frame: Baseline, 6 weeks, and 12 weeks

    Data analyses will include subjects from this study matched to female subjects from the parent study.

Secondary outcomes

  1. Gender differences and changes in craving as assessed by Minnesota Nicotine Withdrawal Scale (MNWS).

    Time frame: Baseline, 6 weeks, and 12 weeks

  2. Gender differences and changes in nicotine dependence as assessed by the Wisconsin Index of Smoking Dependence Motives (WISDM).

    Time frame: Baseline, 6 weeks, and 12 weeks

  3. Gender differences and changes in nicotine dependence as assessed by the Fagerstrom Test of Nicotine Dependence (FTND)

    Time frame: Baseline, 6 weeks, and 12 weeks

  4. Supertaster status as measured by genotyping for taster-receptor genes associated with taste behaviors.

    Time frame: Baseline
