Study Summary
The goals of this project are to determine the effects of varying degrees of cigarette filter ventilation on biomarkers of toxicant exposure and smoking behavior and on subjective responses to the cigarette. The primary aim of this study is to examine the effects of unventilated vs ventilated filter cigarettes on urinary biomarkers of toxicant exposure and smoking behavior (e.g., cigarettes per day, intensity of smoking). The secondary objectives are 1) to examine the effects of cigarette filter ventilation on subjective measures such as cigarette dependence and responses to study cigarettes.
Primary Outcome
Absolute change from baseline level of total NNAL (4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol) at the week 6 visit (ng/g creatinine) measured in urine using liquid chromatography-tandem mass spectrometry (LC-MS/MS).
