The FDA recently gained the authority to regulate the nicotine content of cigarettes. Prior research suggests that smokers who switch to very low nicotine content (VLNC) cigarettes experience reduced addiction to nicotine and are more likely to quit smoking. Currently, the most common method for smokers to reduce their nicotine intake is to reduce their number of cigarettes per day (CPD). No research has compared reducing smokers' nicotine intake by switching to VLNC cigarettes vs by reducing CPD with regard to decreasing dependence or quitting; thus the investigators will examine the two strategies by randomizing smokers to 1) switch to VLNC cigarettes or 2) reduce CPD. In addition, all smokers will use the nicotine patch to help them reduce their nicotine intake.
This study will evaluate behavioral and psychological appeal, toxicity, and effect of e-cigarettes on smoking behavior and nicotine addiction in chronic smokers with serious mental illness (SMI) who have failed to quit smoking. A total of 240 participants will be enrolled and randomly assigned to either receive a supply of e-cigarettes for 8 weeks plus assessments (baseline & weeks 2, 4, 6, 8, 13, & 26) or assessments only. This single-blinded study will provide e-cigarettes and instructions on their safe use. Level of appeal will be inferred from carefully assessed use of e-cigarettes and reduction in combustible tobacco. Qualitative data will also be collected from participants assigned to e-cigarettes, given that unanticipated issues will almost certainly arise in connection with e-cigarette use that can only be captured within a qualitative debriefing at the conclusion of participants' time in the study.
Pilot study to test feasibility of delivering a motivational smoking cessation intervention to low income smokers via a computer tablet.
Electronic cigarettes are battery-powered vaporizers which have a similar feel to tobacco smoking. They do not produce cigarette smoke but rather an aerosol, which is frequently referred to as vapor. E-cigarettes are marketed as less harmful alternatives to smoking. Use and awareness of these devices has grown exponentially in recent years, with millions of people currently using them. The benefits and risks of electronic cigarette use are uncertain. There is no research on the acute oral effects of electronic cigarette in the scientific literature and no hungarian epidemiological survey has been performed in this topic. Regulation of electronic cigarettes varies across countries in the European Union, ranging from no regulation to banning them entirely. The investigators research could help to integrate the regulation of this device in Hungary and in the EU as well. The measurement of acute oral effects of e-cigarette and a hungarian epidemiological survey would be novel in this topic.
Medications for smoking cessation are currently only effective in helping a minority of smokers quit. Drug development is slow and expensive, so there is much interest in optimizing the effectiveness of existing treatments and medications. Current standard doses of nicotine replacement therapy (NRT) are not effective for many smokers and in many cases provide less nicotine compared to when a smoker is smoking their usual number of cigarettes. The proposed study will test if a personalized dose of nicotine patch (up to 84mg) will improve quitting success in those who do not respond to a standard dose of NRT (21mg).
Background: Women Veterans are the fastest growing segment of Veterans Health Administration (VHA) users. This dramatic growth has created challenges for VHA. Gender disparities persist in cardiovascular (CV) and diabetes risk factor control, and rates of depression, anxiety, and mental health comorbidity are disproportionately high among women Veterans. Furthermore, a high rate of women Veterans' attrition from VA care, along with organizational barriers to care, substantiate that organizational changes are needed in order to engage and retain women Veteran VHA users in evidence-based, patient-centered care. Objectives: The Enhancing Mental and Physical health of Women through Engagement and Retention (EMPOWER) QUERI addresses VHA Blueprint for Excellence Strategy 6, by advancing "personalized, proactive, patient-centered" care models, and Transformational Strategy 7.2.g by implementation of innovative care models in women Veterans' health care." The EMPOWER QUERI Program is designed to improve women Veterans' engagement and retention in evidence-based care for three high priority health conditions, i.e., prediabetes, cardiovascular, and mental health. To achieve this impact goal, we propose a cohesive portfolio of projects with the following aims: (1) To use an evidence-based implementation strategy that emphasizes local tailoring of care models, multilevel stakeholder engagement, and systematic evaluation of complex implementation processes in order to enrich organizational capacity for innovations in women Veterans' VHA health care; (2) To implement personalized, proactive, patient-centered innovations in VHA women's health that are acceptable, feasible, satisfactory, relevant, and effective for both providers and patients, thereby encouraging women Veterans' engagement and retention and sustainability of the innovations; and, (3) To generate implementation "playbooks" for our partners that are scalable and serve as guidance for future implementation of a broader array of evidence-based women's health programs and policy. Methods: Three projects will be conducted by an experienced multidisciplinary team. "Tailoring VA's Diabetes Prevention Program to Women Veterans' Needs" is a one-year QI project to be conducted in VA Greater Los Angeles women's health clinics. Women Veterans with prediabetes will select an in-person, peer-led or online gender-specific, evidence-based diabetes prevention program to address their risk behaviors and health conditions. "Facilitating Cardiovascular Risk Screening and Risk Reduction in Women Veterans" will increase identification of CV risk among women Veterans, enhance patient/provider communication and shared decision-making about CV risk, and provide a supportive, coordinated health coaching intervention to facilitate women Veterans' engagement and retention in appropriate health services. "Implementation of Tailored Collaborative Care for Women Veterans" will evaluate implementation of an evidence-based collaborative care model tailored to enhance provider- and system-level capabilities to address women Veterans' anxiety and depression treatment needs, thereby improving organizational primary care-mental health integration (PC-MHI) effectiveness and women Veterans' engagement and retention in PC-MHI. Both implementation research studies will use a modified stepped wedge design and will apply the evidence-based Replicating Effective Programs (REP) implementation strategy. Mixed methods implementation evaluations will focus on investigating primary implementation outcomes of adoption, acceptability, feasibility, and reach. Multilevel stakeholder engagement will be prioritized. Program-wide organizational-, provider-, and patient-level measures and tools will be utilized to enhance synergy, productivity, and impact. As a coherent program of women's health implementation research and quality improvement, the proposed EMPOWER QUERI will constitute a major milestone in achieving BPE strategies and realizing women Veterans' engagement and, ultimately, empowerment in our VHA system.
The purpose of this study is to evaluate reactions to, and choices to self-administer, cigarette smoke with varying nicotine content among low-frequency, non-dependent adolescent/young adult smokers between the ages of 15-25 years.
The purpose of this research is to test a text message intervention for people who are beginning an attempt to quit smoking. The intervention seeks to teach people to think about their cravings to smoke in more helpful ways. The investigators expect that participants receiving the text message craving program will be less likely to begin smoking again compared to participants in a control condition.
This study tests whether a smoking cessation intervention for pregnant women that extends postpartum (Striving to Quit (STQ)) can be implemented and disseminated outside of the research environment that established its effectiveness (40% maintained biochemically verified 6-month abstinence). The research aim is: Is Striving to Quit more effective in achieving postpartum smoking cessation than "First Breath," the current standard of care for pregnant women in Wisconsin who smoke? 250 women will be randomized into one of two study groups. Pregnant women in Group A (n=125) will receive the existing First Breath prenatal intervention. Those in Group B (Striving to Quit (STQ), n=125) will receive all Group A interventions, plus 1 additional prenatal home visit, 3 postpartum in-home smoking cessation counseling visits, 3 postpartum phone calls, and up to an additional $100 in gift cards. The primary outcome will be biochemically confirmed smoking cessation at 6-months postpartum.
