Trial Information

Social Determinants and Smoking Cessation

If you agree to take part in this study, you will receive help to quit smoking, including
written self-help materials, counseling, and a supply of the nicotine patch. Over the next
6 months, you will visit MD Anderson 7 times.

Study Visits:

Your first visit is the "baseline" visit when you enter the study. You will then attend 6
additional in-person visits: Week 0 (1 week after the baseline visit), Week 1, Week 2, Week
3, Week 12, and Week 26.

During the baseline visit you will receive a small, hand-held personal phone and be trained
in how to use it. You will carry this phone with you for 4 weeks. You will use the phone
to answer questions about your mood, stress, and smoking-related issues. You will be asked
to fill out some questions on the phone each time you have an urge to smoke. Also, the phone
will "beep" at random and set times and ask that you answer some questions. This phone will
not wake you during the night and you will be able to wait to answer questions for a few
minutes if it goes off when you are busy. Answering the questions should take about 5-10
minutes. This small, hand-held personal phone will also have a GPS system activated that
will record where you are during the waking hours every day while you are on study.

Study Tests:

The following tests and procedures will be performed at each study visit:

- You will complete some questionnaires that will include questions about your feelings,
moods, and smoking status. These will take 60-90 minutes to complete.

- You will complete a breath test to help estimate (guess) the amount of cigarette smoke
you inhale. The breath test uses a disposable cardboard tube that is attached to the
machine, and you blow a long, slow, steady breath into it.

- At the baseline, Week 12, and Week 26 visits, you will have saliva samples collected
for cotinine tests. To collect the saliva, you will be asked to put a small piece of
cotton in your mouth for a few minutes. These samples will be used to measure the
amount of cotinine in your saliva. Cotinine is a chemical released in your body when
it breaks down nicotine.

- You will have your height, weight, and waistline measured.

You may be contacted by mail, telephone, and/or e-mail during the study to be given
reminders of clinic visits. You will be asked to provide the names and contact information
for family and/or friends for the study staff to contact if the study staff has trouble
reaching you.

Length of Study:

You will be considered off study when you complete the Week 26 visit.

After you return the phone and GPS, all of your information that is stored on the devices
will be erased. After the information is erased from the devices, it cannot be retrieved.

This is an investigational study. The nicotine patch used in this study is FDA approved
and commercially available. You will receive 4 weeks of nicotine patches.
