Using Smartwatches to Monitor Smoking in Real-life Situations
Background: It is important to quickly identify when people are at risk of smoking. Most current methods rely on people reporting when they smoke or what makes them want to smoke. But this can be hard for people to do and may not always be accurate. Other methods use special gadgets to identify smoking movements, but these may not always work well in real life. We want to see if we can use devices available on the market such as smartwatches to identify signs in the body and hand movements that might indicate when someone is about to smoke, is currently smoking, or has just smoked. Objective: To record body signs and hand movements before, during, and after smoking in real-life and in a lab to see how they change when someone is craving cigarettes, while a person is smoking, and after a person has smoked. Eligibility: People who are 21 years or older and smoke, have no college degree or be currently enrolled in college, and are low-income earners. To participate in the study, participants have to pass a breath test that shows they smoke cigarettes and, for women, a urine test to show that they are not currently pregnant. Design: Participants will complete an eligibility survey to see if they qualify to be in the study. If they qualify, they will answer a brief baseline survey that includes questions about themselves, their health, and their smoking behavior. Participants will get a smartwatch to wear for 3 days at home, log each time they are about to smoke and have finished smoking, and answer a 5-question health survey via the app. They will get instructions on how to set up and wear the smartwatch. They will download a mobile application on their phone. The app will collect data from the smartwatch. Participants will then come to the lab but will be asked not to smoke or drink alcohol for at least 12 hours. They will have to take a breath test to show they have not smoked or had alcohol. They will also give a blood sample. In the lab, they will sit in a room where they will be hooked to devices that monitor their vitals such as heart rate and blood pressure for one hour. They will also wear a smartwatch on each hand. While they are in the smoking room, they will go through 3 different phases: (a) pre-smoking where they will be asked to stay seated for about 25 minutes, (b) smoking where they will be asked to smoke as many cigarettes of their choice as they want for about 10 to 15 minutes, (c) post-smoking where they will be asked to stay seated, not smoking, for about 25 minutes. They will answer a brief 10-minute health survey before and after the session. Participation will last for 3 days of home monitoring and 2 visits to the research clinic that last about 2 hours.

Project DEDUCE: Digital Envirotyping to Develop Understanding of Cigarette Smoking and the Environment
Tobacco use is a chronic relapsing condition. That is, even with state-of-the-art treatment, \>70% of smoking cessation attempts end in a return to regular smoking. Research demonstrates that everyday environments associated with smoking trigger craving for cigarettes, provoke smoking, and lead to relapse. However, despite this knowledge, understanding of environmental correlates of smoking has been limited by a reliance on self-report, leading to imprecise information about the physical environments in which people live. To overcome this challenge, the research team has pioneered the development of digital envirotyping, which uses digital tools (e.g., sensors, cameras, artificial intelligence) to efficiently and accurately characterize and categorize environments with the goal of identifying environmental markers of behavior and health. Foundational to the digital envirotyping research is computer vision (CV), a type of artificial intelligence (AI) that enables computer systems to recognize objects and scenes in digital images, mimicking how humans perceive and understand visual information. With CV researchers can extract detailed and accurate information (i.e., objects and location types) about the everyday environments of people who smoke (PWS) and relate that information to smoking behavior. After validating the use of CV, the researchers used CV to develop enviromarkers of relapse risk. Importantly, they identified a novel enviromarker in which people at greater risk for relapse when they quit are exposed to a more consistent level of environment-related smoking risk as they move between their smoking and nonsmoking environments. Research is now needed to advance digital envirotyping and enviromarker development in the field of tobacco addiction. The study will recruit a diverse, national sample of n=500 adults who are interested in quitting smoking. For two weeks prior to quitting, they will undergo photoEMA in which they will take two pictures of their current environment when they smoke, and randomly 10 times per day resulting in \>300,000 images total. Cessation will be supported by nicotine replacement therapy (i.e., nicotine patch). The primary clinical outcome will be days to relapse. Specific aims are to (1) further develop, refine, and validate methods for efficient digital envirotyping at scale, (2) leverage CV and AI approaches to develop enviromarkers of smoking relapse, and (3) conduct analyses to increase understanding of environmental smoking risk in women and individuals with low socioeconomic status.

Clinical Alternatives for Reducing Harm Using E-cigarettes
For patients in cancer care, quitting smoking is critical, but a significant portion of patients in cancer care refuse all components of tobacco treatment, even when offered free of charge. The proposed clinical trial will assess one harm reduction intervention, switching completely from cigarettes to e-cigarettes, among oncology outpatients who smoke and refuse traditional tobacco treatment. This study is a type 1 hybrid effectiveness-implementation trial among oncology outpatients at an NCI-designated cancer center who smoke and refuse all components of tobacco treatment (N=208).

Linking Brain Network Dynamics to Imminent Smoking Lapse Risk and Behavior
Most attempts to quit smoking end in relapse, or a return to regular smoking. One of the biggest threats to cessation is a lapse (i.e., any cigarette use during a quit attempt). Thus, characterizing why lapses occur is essential to understanding and preventing smoking relapse. Functional magnetic resonance imaging (fMRI) is a promising method for characterizing the psychological processes that lead to smoking lapses because it provides a way to measures patterns of brain activity thought to reflect relevant mental processes as they change over time. However, methodological issues have hindered the ability to capitalize on this potential and prevented an understanding of how brain activity and corresponding psychological processes unfold in the critical moments that immediately precede a smoking lapse. The proposed project will address this knowledge gap using a novel fMRI paradigm adapted from a well-validated behavioral lapse task. The goals of the project are to characterize changes in brain activity that lead up to a lapse and to investigate how these changes are related to concurrent affect and subsequent cigarette use.

The Effect of Emotional Freedom Techniques (EFT) in Smokers Failing a Smoking Cessation Program
The National Health Service (NHS) stop smoking service at the Central Lancashire NHS Trust serves a diverse population of smokers, with a very good quit rate and high standards. However, clinical experience predicts that some clients are unlikely to succeed through the NHS smoking cessation program. This special population has difficulty quitting for a variety of reasons. Some relapse over the course of the following two years and return repeatedly to the service. Others, for instance those with health problems, may be highly motivated to quit, but unable to resist their cravings. The purpose of this study is to determine if EFT makes a difference in quit rates with the most challenging population of clients.

Leveraging Community Pharmacists to Optimize Smoking Cessation Services for Rural Smokers in Appalachia
The goal of this clinical trial is to evaluate the effectiveness and implementation of a pharmacist-delivered MTM (medication therapy management) approach, called QuitAid, to quitting cigarette smoking in rural Appalachia. The main questions it aims to answer are: * Is QuitAid, alone or combined with other quitting tobacco treatments, effective? * What makes QuitAid easy or hard to carry out? Is it cost effective? Is it easy to maintain? Treatment: All participants will be given at least 4 weeks of the nicotine patch. Some participants will be randomized (like the flip of a coin) to receive additional treatments (listed below). These groups will be compared to each other to see which combination works best to help them quit smoking. * Smokefree TXT - a texting program that helps people quit smoking * Tobacco quitline - 4 phone sessions to help people quit smoking * 8 weeks of NRT (nicotine replacement therapy in the form of nicotine patches or nicotine patches and lozenge) medication instead of 4 weeks * QuitAid - An MTM program given by the patient's pharmacist. This is a quitting smoking coaching program * Nicotine patch AND nicotine lozenge instead of just nicotine patches

Functional Capacity, Subjective Dyspnea and Fatigue in Smokers
Smoking remains a significant public health problem among the young adult population. Epidemiological studies in Turkey show a steadily decreasing age of smoking initiation and a remarkably high rate of smoking among university-aged individuals. Exposure to secondhand smoke is known to have negative effects on the respiratory system, cardiovascular system, and peripheral muscle function. Impaired lung ventilation, reduced gas exchange, and insufficient oxygen transport due to smoking can lead to decreased exercise tolerance, premature fatigue, and increased perception of exertional dyspnea. These effects can manifest as a decrease in functional capacity even before the development of a clinically significant respiratory disease. Functional capacity is an important indicator reflecting an individual's ability to perform daily living activities and is frequently assessed in clinical research using submaximal exercise tests. The 6-Minute Walk Test is a widely used, valid, and reliable test for assessing cardiorespiratory endurance and overall functional status. Similarly, the 1-Minute Sit-Stand Test is recommended as a practical and applicable method for evaluating lower extremity muscle endurance and functional performance. Dyspnea is a multidimensional symptom reflecting an individual's subjective perception of respiratory discomfort and is assessed using scales such as the Modified Medical Research Council and the Borg Dyspnea Scale. The Turkish Thoracic Society's dyspnea assessment reports indicate that exertional dyspnea may increase in smokers even if respiratory function tests are within normal limits. Fatigue, on the other hand, is a significant symptom that negatively affects an individual's daily living activities and physical functionality, arising from inflammatory processes, impaired oxygenation, and decreased physical activity levels associated with smoking. The Fatigue Severity Scale is a validated and reliable scale for assessing the impact of fatigue on an individual's physical and social life. While studies in the literature examine the effects of smoking on respiratory function and exercise capacity, studies that address the relationship between functional capacity and subjective dyspnea and fatigue in young adult smokers are limited. In particular, evaluating functional test results such as the 6-Minute Walk Test and the 1-Minute Sit-Stand Test together with dyspnea and fatigue perception will contribute to the early identification of subclinical functional effects. The aim of this study is to examine the relationships between functional capacity (6-Minute Walk Test, 1-Minute Sit-Stand Test, and Timed Up and Go Test) and subjective dyspnea (Modified Medical Research Council Scale - mMRC) and fatigue level (Fatigue Severity Scale) in young adult smokers aged 18-30 years. The findings of this study are expected to draw attention to the functional effects of smoking in young adults, contribute to the development of preventive health approaches, and facilitate the planning of physiotherapy-based assessment and intervention programs.

Smoking Cessation for Depressed Smokers
Objectives: Primary Aim: To conduct a preliminary randomized trial in smokers with current recurrent major depressive disorder (MDD), current MDD with a single episode of 2 years or more, and current dysthymia comparing combined cognitive behavioral analysis system of psychotherapy (CBASP) and standard smoking cessation treatment (ST) (CBASP/ST) to combined Health Education and ST treatment (HE/ST) to: 1\. Examine the effects of CBASP/ST on both short and long-term point prevalence abstinence Secondary Aims: 1. To test the hypothesis that depressed smokers in the CBASP/ST treatment will experience greater decreases in depressive symptoms from baseline to each of our follow-up assessment points, compared to depressed smokers in the HE/ST treatment, and; 2. That depressed smokers in the CBASP/ST treatment will experience greater improvements in psychosocial functioning from baseline to follow-up assessment points, compared to depressed smokers in the ST treatment. 3. To evaluate between subject neurophysiological predictors of abstinence at 3 and 6 months, and: 4. To evaluate within-subject changes in neurophysiological responses to emotional and smoking-related stimuli across treatment sessions, and the relation of these changes to abstinence and depressive symptoms at end of treatment, and 3- and 6-months.

A Pragmatic Trial of Chronic Disease Approaches to Ameliorate Tobacco Related Cardiovascular Disease Health Disparities
This project will evaluate a proactive outreach intervention for tobacco cessation among primary care BIPOC populations who smoke in two health systems across the region. Compared with Whites, BIPOC populations in the US experience disproportionate health consequences from commercial cigarette use. Few evidence-based cessation treatments (EBCTs) have been specifically developed, evaluated, or implemented for BIPOC populations. Moreover, uptake of EBCT (e.g. medication, counseling) is lower among BIPOC populations. Reasons for the failure to engage BIPOC patients in EBCTs are complex and multi-level (e.g., patient, provider, healthcare system). To address these gaps, the investigators will assess the added effectiveness of an approach to augment the standard of care with longitudinal proactive outreach to connect BIPOC adults with EBCT. The proposed multi-level intervention leverages the electronic health record to identify patients who smoke, who can then be proactively engaged via culturally tailored outreach to connect them to EBCT. The proactive approach may circumvent experiences of bias within the healthcare system and thus enhance engagement.
