  Purpose
This study will examine how menthol affects smoking when menthol smokers switch to non-menthol cigarettes. Participants will smoke their preferred brand (control) or Camel Crush cigarettes, which have the ability to be menthol or non-menthol. Participants given Camel Crush cigarettes will smoke them as menthol, then non-menthol cigarettes for 15 days each. Participants will provide breath and urine samples, track cigarette usage and complete smoking topography assessments of smoking behavior.

Primary Outcome Measures:
  • Smoking Topography- Puff Volume [ Time Frame: over 35 day study period ]
    The total puff volume for a single subject is the sum of puff volumes for a subject's cigarette smoked during the study session. The mean puff volume for the subjects will be used to examine the effect of cigarette menthol on smoking topography. The values provided are the average of subjects at study Day 5 (completion of baseline smoking own cigarettes), Day 20 and Day 35.

  • Smoking Topography- Carbon Monoxide Boost [ Time Frame: Measured before and after each cigarette smoked at study sessions ]
    Carbon monoxide content in exhaled breath samples is measured before and after each cigarette smoked during study sessions. CO boost is the amount in parts per million that the subject's CO increases.

  • Nicotine Levels [ Time Frame: 35 days ]
    Urine nicotine levels will be measured to examine the effect of cigarette menthol on harm exposure measures. Participants provided samples on the final day of each period. NNK and 1-hop were not analyzed, total nicotine metabolites were assayed.

  • Subjective Rating of Cigarettes [ Time Frame: Immediately after a cigarette smoked at the study session ]
    Subjects completed a visual analog scale rating each cigarette smoked at each session. Subjects rated characteristics of the cigarette on a scale represented as a continuous horizontal line 10 cm long. Subjects drew an intersecting line to represent their rating. The rating reported is for the taste of the cigarette at the end of the period averaged across subjects in the group. A rating of 0 corresponds to Very Bad and a rating of 100 to Very Good for taste. There is no better or worse outcome for higher or lower ratings for taste.


Enrollment: 87
Study Start Date: September 2010
Study Completion Date: September 2011
Primary Completion Date: September 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Nonmenthol
Participants switch from menthol to non-menthol cigarettes.
Other: Menthol to non-menthol
Switch from smoking menthol to non-menthol cigarettes.
No Intervention: Menthol
Participants smoke own brand of menthol cigarettes.

Detailed Description:
This study will examine how menthol affects smoking behaviors and biomarker level when menthol smokers switch to non-menthol cigarettes. Participants will initially smoke their preferred brand (control) cigarettes, followed by smoking Camel Crush cigarettes, which have the ability to be menthol or non-menthol. Participants given Camel Crush cigarettes will smoke them as menthol, then non-menthol cigarettes for 15 days each. Participants will provide breath and urine samples to measure smoke exposures, track cigarette usage to establish changes in daily cigarette consumption and complete smoking topography assessments of smoking behavior, such as puff volume.
