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.

Further study details as provided by University of Pennsylvania:

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
