E-Cigarette Effects on Markers of Cardiovascular and Pulmonary Disease

This study is designed to enhance the understanding of the possible health effects of e-cigarette use by relating the acute and long-term use of e-cigarettes and conventional cigarettes ("products") to well-validated cardiovascular and pulmonary disease biomarkers. Participants will be enrolled in 3 groups: exclusive e-cigarette users, exclusive cigarette smokers, and a control group of never-users. Participants can expect up to 4 weeks of study participation.

UW Quitting Using Intensive Treatment Study (QUITS) (QUITS)

This research will determine whether two highly promising modifications to varenicline treatment (i.e. use of a nicotine patch adjuvant and extended 24-week duration) produce superior smoking outcomes when they are either used together or alone. Despite their promise, the proposed modifications have never been experimentally evaluated relative to standard varenicline pharmacotherapy. Thus, this innovative research will produce novel evidence regarding how best to help smokers quit, and thereby address the leading cause of preventable mortality and morbidity related to cardiovascular and pulmonary diseases.

Inclusion criteria: Participants must: plan to stay in the area for the next 12 months, ability to read and write in English, smoke on average ≥5 cigarettes per day over the last 6 months, be ≥18 years old, desire to quit smoking but not be engaged currently in cessation treatment, report no use of pipe tobacco, cigars, snuff, e-cigarettes or chew in the last 30 days, have reliable phone access, willing and able to use both nicotine patch and varenicline, access to transportation to come to our clinic and, if female, not be pregnant and be using an acceptable birth control method/ method to prevent pregnancy. Smoking will be biochemically confirmed via a carbon monoxide (CO) breath test at the orientation session visit. Potential participants must have a CO test result of ≥5ppm for eligibility to participate. Exclusion criteria: Current treatment for schizophrenia or a psychotic disorder; suicidal ideation in the past 12 months; history of suicidal attempts within the last 10 years; on dialysis or being told you have severe kidney disease; hospitalization for a stroke, heart attack, congestive heart failure or uncontrolled diabetes mellitus within the past year; history of seizure within the last year; currently taking Wellbutrin, Zyban, or Buproprion (Contrave is a weight-loss drug that has Wellbutrin in it) for reasons other than to quit smoking or taking to help quit smoking and not willing to stop for duration of the study; currently using any form of nicotine replacement (e.g., nicotine patch, nicotine gum, nicotine lozenge) or using Chantix or varenicline and not willing to stop for duration of the study; had a reaction to the nicotine patch that prevented them from continuing to use it; or currently participating in another smoking cessation study. Pregnancy: Even though we screen out participants who are pregnant, plan to become pregnant, nursing, or are unwilling to take steps to avoid pregnancy, there is a chance that a participant eligible at consent could become pregnant later. She would then be considered part of a vulnerable group. Given the longitudinal nature of the research, a participant who becomes pregnant after enrolling will be given the choice of whether to 1) continue in the study (for counseling and other assessments) and agree to immediately stop taking study meds for the remaining duration of the study and return any unused medications, OR 2) withdraw. No further medications will be given to this study participant while in the study. Incarcerated Individuals: Incarcerated individuals will not be enrolled in this study. However, given the longitudinal nature of the research, participants could be incarcerated for periods during their participation. If study staff learn that a participant is incarcerated at a time point before or at their Week 8 phone call, the participant will be withdrawn from the study. If study staff learn that a participant is incarcerated subsequent to Week 8, the participant will not be withdrawn unless that incarceration will take them beyond the study period. In that case, staff will not contact the participant while incarcerated and will not provide any treatment (counseling or medication) nor conduct any assessments during the period of incarceration. Services and assessments will be re-initiated if the participant is released at a later study time point.
