What is the purpose of this trial?

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.

What Are the Treatments Tested in This Trial?

Interventions

• Unventilated Cigarette Filter
• Ventilated Cigarette Filter

Trial Overview The study is testing the effects of cigarettes with ventilated filters versus unventilated filters on toxicant exposure and smoking behavior. Participants will be monitored for changes in urinary biomarkers and their responses to the cigarettes.

How Is the Trial Designed?

Group I: Ventilated Cigarette Filter Experimental Treatment 1 Intervention

Filters with approximately 24-32% filter ventilation

Group II: Unventilated Cigarette Filter Experimental Treatment 1 Intervention

Filters with approximately 0-5.0% filter ventilation
