What is the purpose of the study?
This study looks at how smokers break down one of the toxins in cigarette smoke and other cancer-causing chemicals in cigarettes. Some people are better than others at breaking down these toxins and getting rid of them as harmless chemicals. Your participation will help us better understand how people break down toxins and if differences in metabolism are related to cancer risk.
How often are the clinic visits?
You will attend 3 clinic visits: an orientation visit to learn more about the study (1 hour), one physical exam to determine your final eligibility (1 hour), and one 6 hour lab session.
What will I be doing in the study?
You will be asked to complete questionnaires about your health and smoking history. During the study will also collect blood and urine samples and cells from your mouth. At the 6 hour lab session, you will be given a small amount of liquid to drink which contains a chemical called deuterated phenanthrene and you will collect all your urine while you are here for those six hours.
Will I be compensated?
If you attend all three visits and complete all collections, you will be compensated $150 for your time and effort.
