Smoking
Conditions
Brief summary
This study will evaluate exposure to tar and nicotine from two menthol cigarette products and provide a basis for comparing mouth-level exposure when smokers smoke the two cigarette products. Mouth-level exposure is the measurement of substance trapped in the cigarette butt after smoking the cigarette. Other purposes of this study are to: * Compare the plasma cotinine, a byproduct of your body's processing of nicotine, levels found in users after smoking each of two different cigarettes. * Find out the daily mouth-level exposure to cigarette tar and nicotine from smoking each of two different cigarettes in adult smokers. * Determine if certain measures of nicotine dependence change based on the type of cigarette smoked * To compare product liking and intent to use it again.
Detailed description
The study will consist of one group of approximately 32 adult subjects randomly assigned to the order in which they will smoke two study menthol cigarette products (including one comparator product and one test product). Subjects will smoke each study product exclusively for approximately one week prior to a test visit, with a different product smoked each week over a two-week period. Cigarette butts will be collected the day prior to each test visit for determination of MLE tar and nicotine levels. Blood samples will be collected at each test visit for determination of plasma cotinine levels. Subjects will provide responses to questions during each test visit to assess their cigarette smoking and cigarette butt collection behavior during the preceding day.
