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 [ Time Frame: during study (up to 15 days) ] [ Designated as safety issue: Yes ]
    The total puff volume, mean puff volume will be used to examine the effect of cigarette menthol on smoking topography.

  • biomarkers of harm exposure [ Time Frame: during study (up to 15 days) ] [ Designated as safety issue: Yes ]
    CO boost, NNK, and 1-HOP levels will be measured to examine the effect of cigarette menthol on harm exposure measures.

Secondary Outcome Measures:
  • exhaled breath condensate [ Time Frame: during study (up to 15 days) ] [ Designated as safety issue: No ]
    Exhaled breath condensate samples will be measured for biomarkers indicating changes from smoking menthol cigarettes.

  • beliefs, attitudes and knowledge [ Time Frame: during study (baseline, 15 days) ] [ Designated as safety issue: No ]
    Beliefs, attitudes and knowledge about menthol and nicotine levels of this product will be assessed at baseline as well as at followup phone call.

Estimated Enrollment: 40
