Study Summary

This trial will test the effects of different degrees of cigarette filter ventilation on biomarkers of exposure to toxins and on smoking behavior. Additionally, the study will explore how these changes impact a smoker's dependence on cigarettes and their subjective responses to smoking.

Who is the study for?
This trial is for regular cigarette smokers who are at least 21 years old and have their smoking status confirmed biochemically. It's not suitable for individuals with unstable health conditions, those on fluctuating medications, or pregnant or nursing women.Check my eligibility
What is being tested?
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.See study design
What are the potential side effects?
While specific side effects are not detailed, potential risks may include changes in smoking behavior due to different filter types which could affect toxin intake.
