Smoking Topography and Harm Exposure in Menthol Cigarettes
Not Provided

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.
