Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
* Specific Aim 1: Produce important new data on how to treat smoking optimally by conducting an open label comparative effectiveness trial (CET) that for the first time directly contrasts the two smoking cessation pharmacotherapies with the strongest extant evidence of efficacy: combination NRT and varenicline.
* Specific Aim 2: Determine the impact of smoking cessation on biomarkers and health risk factors, especially those relevant to CVD, in today's smokers, which will elucidate the mechanisms via which cessation benefits health.
* Specific Aim 3: Identify which individuals are at greatest risk for exacerbation of biomarkers or risk factor status due to continued smoking, and who will benefit most from cessation. This will help identify individuals who are most in need of cessation intervention. While all smokers need to quit, this evidence could ultimately be used to help focus treatment and motivate smokers and clinicians to intervene more intensively with patients at greatest risk.
Two secondary aims are to use the results of Primary Aim 1 to develop a treatment assignment algorithm for the optimal treatment of today's smokers and to use the results from Primary Aim 2 to determine the relation of health biomarkers to clinically meaningful disease outcomes such as CVD events.
We will re-recruit as many smoking and non smoking participants from our past longitudinal cohort study("Wisconsin Smokers' Health study"; NCT01122238) in 2004. We will then recruit additional smokers to participate in the comparative effectiveness trial and join the longitudinal cohort..
All participants who enroll will complete questionnaires about their demographics, smoking history, withdrawal symptoms, affect, alcohol use, stressors, medication usage and diet. They will also complete a structured clinical interview to assess mental health. They will provide blood samples for testing of various markers of cardiovascular disease and risk as well as for genetics testing. They will all have carotid ultrasounds, pulmonary function tests, arterial tonometry assessments, and 12-lead ECGs. Participants in Madison will also have a treadmill stress test. Participants will wear a pedometer for 1 week and record the daily number of steps. Participants will provide permission for staff to review their medical charts to assess smoking-relevant diagnoses and treatment. These assessments will occur at baseline and again 3 years later. A smaller subset of these assessments will also be conducted 1 year after enrollment. Participants will also complete brief phone assessments at 6-month intervals up to the 3-year visit.
Interested and eligible smoking participants from the original cohort study and all newly recruited participants will enroll in a new smoking cessation intervention study. Participants in the cessation treatment study will be randomly assigned to receive the nicotine patch, nicotine patch + nicotine lozenge or varenicline. If the participant from the original cohort study is not eligible to use all study medications but is otherwise eligible for cessation treatment, s/he will be assigned to a non-randomized treatment arm and will receive nicotine patch (if appropriate). All cessation participants will receive 6 individual counseling sessions.

Study Groups

Effectiveness of Nicotine patch only
Nicotine Patch
Participants will receive 12 weeks NRT. Patch dosing will be 8 weeks of 21 mg, then 2 weeks of 14 mg, then 2 weeks of 7 mg (those smoking 5-10 cigs/day will receive reduced patch dosing). Medication use will start on the morning of their assigned quit day. They will be urged to use 1 patch/day, unless it produces adverse effects.
Effectiveness of Combination NRT
Nicotine lozenge
Participants will receive 12 weeks NRT. Participants will be given 2 mg or 4 mg lozenges based on morning smoking latency, and will be given package insert use instructions. Medication use will start on the morning of their assigned quit day. They will be urged to use at least 5 pieces/day, unless this amount produces adverse effects.
Nicotine Patch
Participants will receive 12 weeks NRT. Patch dosing will be 8 weeks of 21 mg, then 2 weeks of 14 mg, then 2 weeks of 7 mg (those smoking 5-10 cigs/day will receive reduced patch dosing). Medication use will start on the morning of their assigned quit day. They will be urged to use 1 patch/day, unless it produces adverse effects.
Effectiveness of Varenicline [Chantix]
Varenicline
Participants will receive 12 weeks of pharmacotherapy during the post-quit period plus an additional 7 day pre-quit run-in. Participants will be asked to take a 0.5 mg pill once a day for the first 3 days and then increase to a 0.5 mg pill twice a day (8 hours apart) for 4 days. On the 8th day, their target quit date, they will increase to their target maintenance dose of a 1 mg pill twice daily. If participants report significant adverse events such as nausea, a dose reduction to two 0.5 mg doses per day will be advised.

Medication use will start on the morning of their assigned quit day. They will be urged to use at least 5 pieces/day, unless this amount produces adverse effects.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* smoke 5 or more cigarettes per day,
* desire to quit smoking but not be currently engaged in cessation treatment,
* be medically eligible to use either combination NRT or varenicline,
* have reliable phone access,
* if female, must not be pregnant and must be willing to use an acceptable birth control method.
Exclusion Criteria
* end-stage renal disease with hemodialysis;
* prior suicide attempts within the last 5 years or current suicidal ideation;
* diagnosis of and/or treatment for schizophrenia;
* other psychotic disorders or bipolar disorder within the last 10 years;
* current PHQ-9 score indicative of moderately severe depression;
* severe untreated hypertension \>200/100 mmHg;
* currently taking Wellbutrin, Zyban or bupropion;
* hospitalized for a stroke, heart attack, congestive heart failure or diabetes within the last year;
* used pipe tobacco, cigars, snuff or chew more than twice in the past week.
It should be noted that if any incidental findings appear in any of the cardiology tests (e.g., ultrasound, tonometry, ECG, or exercise stress test; see forms in Supplemental Information section of application), the study cardiologist (Dr. Stein or his designee) will be assign the participant to the non-randomized treatment arm and they will be given the nicotine patch and the same counseling intervention as CET participants. They will not be included in the CET analyses. This will be done to properly address the cardiovascular risk warning from the FDA regarding varenicline (Chantix).
