Study Details

Study Description

Brief Summary

This study examines the potential effect of reducing nicotine content or menthol or both in men. It will also examine whether there are gender differences in manipulating tobacco flavors and nicotine concentrations in cigarettes on smoking behavior.

Condition or Disease	Intervention/Treatment	Phase
Nicotine Dependence	Other: Reduced Nicotine Non-Menthol (RNC) Other: Reduced Nicotine Menthol (RNC-Men) Other: Conventional Nicotine Non-Menthol (CN)	N/A

Detailed Description

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.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: Reduced Nicotine Non-Menthol (RNC) Study participants will be randomized from their own brand of menthol cigarettes to the reduced nicotine non menthol cigarettes (RNC: NRC 200; 0.07 mg nicotine yield cigarettes without menthol) during the 6 week experimental phase.	Other: Reduced Nicotine Non-Menthol (RNC) 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
Experimental: Reduced Nicotine Menthol (RNC-Men) Study participants will be randomized from their own brand of menthol cigarettes to the reduced nicotine menthol cigarettes (RNC-Men: NRC 201; 0.07 mg reduced nicotine content menthol cigarettes) during the 6 week experimental phase.	Other: Reduced Nicotine Menthol (RNC-Men) 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
Experimental: Conventional Nicotine Non-Menthol (CN) Study participants will be randomized from their own brand of menthol cigarettes to the regular/conventional nicotine non menthol cigarettes (CN: NRC 600; 0.8 mg nicotine content) during the 6 week experimental phase.	Other: Conventional Nicotine Non-Menthol (CN) Switch from own brand of cigarette to an investigational tobacco product which contains conventional nicotine yield.

Outcome Measures

Primary Outcome Measures

Gender differences and change in number of investigational tobacco product(s) smoked per day as assessed by the Timeline Follow-Back (TLFB) [Baseline, 6 weeks, and 12 weeks]
Data analyses will include subjects from this study matched to female subjects from the parent study.

Secondary Outcome Measures

Gender differences and changes in craving as assessed by Minnesota Nicotine Withdrawal Scale (MNWS). [Baseline, 6 weeks, and 12 weeks]
Gender differences and changes in nicotine dependence as assessed by the Wisconsin Index of Smoking Dependence Motives (WISDM). [Baseline, 6 weeks, and 12 weeks]
Gender differences and changes in nicotine dependence as assessed by the Fagerstrom Test of Nicotine Dependence (FTND) [Baseline, 6 weeks, and 12 weeks]
Supertaster status as measured by genotyping for taster-receptor genes associated with taste behaviors. [Baseline]
