Following the quit date, you will attend six (6) more 70-minute counseling sessions. You will also attend 2 additional visits at 3 months and 6 months from your quit date. At each of these visits, you will be asked to fill out 2-3 questionnaires on mood and smoking behavior and to provide a breath test to measure the amount of carbon monoxide in your blood. You will be asked questions about symptoms you may be having and the medications you are taking. You will be asked to fill out 5-6 questionnaires on withdrawal symptoms, confidence in quitting smoking, and the quality of your relationships with others at some of these visits. If you are unable to attend your end-of-treatment, 3-month or 6-month visits, you may be asked to provide a saliva sample to measure the amount of cotinine in your blood, a chemical produced by the breakdown of nicotine during smoking. This sample will be taken using a dental roll (cotton swab) placed in the mouth for several minutes to absorb saliva. At the 3-month and 6-month follow-up visits, you will be also asked questions about any current problems with depression.
