  • Contingency Management for Smoking Cessation

    open to eligible people ages 18 years and up

    The prevalence of smoking in the homeless population (70%) is over 4 times that of the general population (15%). Homeless adults have not experienced similar declines in tobacco use as the general population has over the past three decades. Homeless adults are interested in smoking cessation and make quit attempts, but are less successful in quitting smoking than the general population. Trials of group behavioral counseling and pharmacotherapy for smoking cessation have not led to substantial long-term abstinence (i.e., abstinence for 6 months or more), suggesting that these interventions alone are insufficient to improve quit rates among homeless adults. Many homeless adults seek health care in safety net clinics; these clinics could bring cessation interventions to scale. Contingency management is a powerful behavior change intervention that reinforces positive health behaviors through the provision of modest incentives (e.g., cash). In this pilot randomized controlled trial, the investigator will test the feasibility and acceptability of a contingency management intervention that provides incentives for smoking cessation for people experiencing homelessness.

  • Engaging Sexual and Gender Minority Cigarette Smokers Into Social Media-based Treatment

    open to eligible people ages 18 years and up

    This research study will evaluate the preliminary efficacy of Pride Posts Plus, a social media-based smoking cessation treatment. A pilot randomized trial (N=120) will compare Pride Posts Plus, which includes a gamification element, to Pride Posts (without gamification) and to a usual care treatment. Participants will be adults who smoke, identify as sexual or gender minorities, and use Facebook. The primary outcome will be biochemically verified 7-day abstinence from smoking at 3 and 6 months. Secondary outcomes will be treatment engagement, a quit attempt (y/n), and thoughts about tobacco abstinence at 3 and 6 mos.

  • Lung Macrophage Populations and Functions in Chronic Obstructive Pulmonary Disease (COPD)-Susceptible Smokers

    open to eligible people ages 40-75

    Chronic Obstructive Pulmonary Disease (COPD) is a heterogeneous disease that affects only a fraction of those who smoke tobacco. The origin of this variability in susceptibility to develop COPD is unclear, but understanding its underlying biology has important implications for our ability to design suitable preventative and therapeutic strategies for its management. This Department of Defense (DOD) discovery research proposes to develop methodologies and generate preliminary data needed to lay the foundation for a large study that would investigate the underlying biological susceptibility of those who smoke tobacco to develop COPD.

  • N-Acetylcysteine for Smoking Cessation in Tobacco and Cannabis Co-Use

    open to eligible people ages 18 years and up

    Tobacco and cannabis co-use is a common and growing public health problem, especially in states that have legalized cannabis. There are no pharmacologic treatments for co-occurring tobacco and cannabis use. Co-use may make quitting either substance more difficult, given the synergistic effects of cannabis and nicotine on neurobiological systems that mediate reward and shared cues reinforcing co-use. N-acetylcysteine (NAC), an FDA-approved medication and over-the-counter supplement, has shown promise in animal studies and randomized controlled trials (RCTs) in reducing tobacco and cannabis craving and use.

  • Transcranial Magnetic Stimulation and Tobacco Use Disorder

    open to eligible people ages 18-45

    The purpose of this study is to determine if brain stimulation using repetitive transcranial magnetic stimulation (rTMS) directed at different parts of the brain can decrease feelings of cigarette craving and symptoms of cigarette withdrawal, and also if men and women have different responses to rTMS. Participants will visit the University of California, Los Angeles (UCLA) five times: First, for in-person screening, then for four rTMS sessions, stimulating three different brain regions and also a sham control stimulation. The sham procedure is similar to a placebo, and will use a lower-intensity stimulation than the active stimulations. Everyone in the study will be assigned to all four treatment arms (one sham stimulation, and active stimulation of three different brain regions), and they will take place in a random order.Before and after each rTMS session, a brief MRI will be performed, and participants will be asked to fill out questionnaires that describe how they are feeling.

  • Cardiovascular Assessment of the Effects of Tobacco and Nicotine Delivery Products

    Sorry, in progress, not accepting new patients

    The overarching goal of this project is to develop a panel of cardiovascular risk biomarkers that can detect differences in the cardiovascular safety of various tobacco products, whether conventional, new or emerging, in order to help the FDA with the task of regulating them. This will be achieved through 4 aims: Aim 1: Determine the relative contributions of nicotine and combustion products to the cardiovascular risk of active cigarette smoking. Aim 2: Determine which cardiovascular risk biomarkers are affected by exposure to secondhand smoke. Aim 3: Determine the cardiovascular risk of smokeless tobacco use. Aim 4: Determine the cardiovascular risk of electronic cigarettes and the respective contributions of nicotine and electronic cigarette vapor.

  • Effect of Packaging on Smoking Perceptions and Behavior

    Sorry, in progress, not accepting new patients

    The investigators are addressing two critical areas identified by the FDA: the impact of cigarette packaging and labeling on consumer perceptions and on smoking behavior; and the effectiveness of graphic warning labels on communicating risk of tobacco products. In a randomized controlled trial (RCT), investigators will enroll committed smokers who have no intention of quitting in the next 6-months. The three study arms will be: a) a blank pack with all marketing materials removed (PP); b) The Australian graphic warning images (Australian model-AM); or c) a standard pack with all marketing materials unaltered (ST). The study includes a three month purchasing intervention and continued follow-up through 12 months. Throughout the study interactive text messaging assessments will be used to measure acute and persistent impact of labeling and marketing on perceptions of tobacco products, subjective effects of consumption, awareness of tobacco-related harms, tobacco use behavior, and quitting motivation. At three separate time points, participants will: a) complete a web-based questionnaire b) provide a saliva sample for cotinine analysis. The rigorous design and extensive objective measurements are significant innovations on the currently published research in this field and should lead to significant advances in tobacco regulatory science.

  • Financial Incentives for Smoking Treatment II

    Sorry, accepting new patients by invitation only

    Financial incentives for motivating changes in health behavior, particularly for smoking and other morbid habits, are increasingly being tested by health insurers, employers, and government agencies. However, in using incentive programs for smoking cessation, key unanswered structural and theoretical questions remain regarding their effectiveness, acceptability to patients, and economic sustainability. This trial aims to advance the science and implementation of financial incentives for smoking cessation interventions among high-risk, hospitalized smokers. The investigators will pursue two specific aims: 1) comparing the impact of three approaches for smoking cessation on smoking abstinence, use of evidenced-based therapy, and quality of life and 2) comparing the short-term and long term return on investment of using goal directed and outcome-based financial incentives to promote smoking cessation.

  • Secondhand Smoke Respiratory Health Study

    Sorry, in progress, not accepting new patients

    Exposure to secondhand tobacco smoke (SHS) is associated with diverse health effects in nonsmokers. Flight attendants (FA) who worked on commercial aircraft before the ban on tobacco smoking (exposed FAs) had high, long-term levels of occupational exposure to SHS and are a unique population for the study of long-term health effects of chronic exposure to SHS. In previous studies, we have shown that many never-smoking SHS-exposed FAs to have curvilinear flow-volume loops, decreased airflow at mid- and low-lung volumes, and static air trapping (elevated residual volume to total lung capacity ratio [RV/TLC]), abnormalities that are not diagnostic of overt Chronic Obstructive Pulmonary Disease (COPD), but do implicate the presence of an obstructive ventilatory defect, and are consistent with what has been recently described as preserved ratio impaired spirometry (PRISm). The main objective of the study is to determine the effect of a bronchodilator to counter the physiologic abnormalities that are observed in the population of never-smoking SHS-exposed FAs as both proof of concept of the presence of an obstructive lung disease and as a possible therapeutic option to counteract the adverse respiratory effects of chronic exposure to SHS.
