Outcome Measures
Primary Outcomes (3)
Puff Topography
total inhalation volume from smoking behavior in the laboratory
Baseline to week 4
Ratings of Psychological Reward
Subjective response to smoking, as measured by self-reported psychological reward (scale) of the modified Cigarette Evaluation Scale, administered after smoking. The minimum value is 1 and the maximum value is 7; with 7 indicating greater psychological reward.
Baseline to week 9
Hypothetical Purchasing of Non-Menthol Very Low Nicotine Cigarettes (VLNCs)
Purchasing of non-menthol very low nicotine cigarettes in the Experimental Tobacco Marketplace (ETM) task 1 and 2. Product units purchased per cigarette price displayed in the ETM, displayed as milligrams of nicotine. Prices are $0.12, $0.25, $0.5, $1, $2, $4, $8, and $16 per cigarette. Data are presented as units purchased on a log scale, per recommended best practices.
Assessed during tobacco purchase tasks completed at week 5

Study Arms (2)
Menthol very low nicotine cigarette (VLNC), then non-menthol VLNC
EXPERIMENTALParticipants will smoke menthol flavored very low nicotine cigarettes in their home environment for 7 days. At the end of 7-days, they will also smoke one menthol flavored very low nicotine cigarette in the laboratory.
Non-menthol very low nicotine cigarette (VLNC), then menthol VLNC
EXPERIMENTALParticipants will smoke non-menthol flavored very low nicotine cigarettes in their home environment for 7 days. At the end of 7-days, they will also smoke one non-menthol flavored very low nicotine cigarette in the laboratory.
Interventions
Participants will be randomized to smoke either menthol non-menthol flavored very low nicotine cigarettes in their home environment for 7 days and in the laboratory first and then crossed over to receive the opposite intervention. The study consists of two treatment periods of 7 days separated by a 1 week wash-out period

Limitations and Caveats
We focused on young adults who smoke menthol cigarettes. Findings may not generalize to non-menthol smokers or to different age groups. We did not include menthol and non-menthol normal nicotine cigarette conditions. Participants were not blinded to the cigarette nicotine content to model real-world conditions where consumers are aware of the cigarettes they smoke.
