Who can participate in this study?
This study is for women between the ages of 18 and 35 who currently smoke and are taking birth control pills.

What is the purpose of the study?
This study is being done to investigate the effect of hormones on mood, stress and withdrawal in women who are taking birth control pills.

How often are the clinic visits?
You will attend a total of ten clinic visits. The first clinic visit is an Orientation Visit where you will learn more about the study, ask any questions you may have and meet the study staff. The second visit is a Screening Visit where your eligibility for study participation will be determined. Once you are accepted into the study you will attend eight visits over an eight-week time period. Specifically, you will attend four clinic visits over two eight-day testing periods. Visits are held Monday through Friday between the hours of 7am and 6pm. Visits will last up to 4 1/2 hours.

What will I be doing in the study?
At each clinic visit you will have your blood pressure, heart rate, weight and carbon monoxide levels measured. You will also fill out several forms and questionnaires about your health, mood and smoking behavior. At seven of the visits we will collect blood samples to measure your hormone and nicotine levels. While in the study you will also smoke cigarettes in our lab, use nicotine nasal spray, and quit smoking for two 14-hour periods.

While participating in the study you will also collect saliva samples and complete questionnaires from home. The questionnaires will be done three times per day for two one-week periods and will be collected on a on a study supplied Electronic Data Capture Device. These questionnaires will be about your mood, stress level, withdrawal symptoms and smoking behavior.

Finally, while in this study, you will switch to a study supplied birth control pill and you will also take progesterone or placebo pills (sugar pills) twice a day for two one-week periods. Progesterone is a hormone that occurs naturally during the menstrual cycle and is an FDA-approved medication. The most common side effect of progesterone is fatigue.

Will I be compensated?
If you come in for all the visits, do all the procedures and fill out all of the forms, then you will be paid up to $890 for your participation. You will receive cash payments at the end of each clinic visit.
