In order to reduce the prevalence of cigarette smoking among Veterans, it is vital that healthcare providers offer effective tobacco treatment to all Veterans who smoke, including those not ready to make a quit attempt. Smoking treatments currently available to Veterans who are not ready to quit are only weakly effective. This project will generate new knowledge about the effectiveness of a promising varenicline-based intervention designed to increase quit attempts and long-term abstinence in Veterans who are initially not ready to quit. This project has great potential to engage Veterans not ready to quit smoking in treatment that increases quit attempts and quitting success, thereby reducing morbidity and mortality caused by smoking in Veterans.
NCT06745258
Lung cancer is the leading cause of cancer-related death among Veterans with 90% of cases attributable to smoking. Lung cancer screening (LCS) combined with smoking cessation saves the most lives. ICARE-LCS seeks to decrease health inequality and improve Veteran health by reducing smoking rates among Veterans receiving LCS. ICARE-LCS will use implementation methods to inform national cancer prevention efforts and build infrastructure necessary to support broad implementation of high-impact tobacco dependence treatment (TDT) processes in LCS programs.
NCT06543407
To compare the efficacy of e-cigarette (e-cig) provision with or without behavioral support (SWITCH IT) delivered via telehealth to reduce harm among smokers with MI who cannot quit smoking and are not ready to pursue cessation treatment, and to examine self-regulation (using e-cigs instead of cigarettes to cope with stress/distress and self-efficacy) as a potential mechanism for behavior change from SWITCH IT
NCT06687577
Individuals prone to suicidality are typically excluded from tobacco cessation interventions even though they are disproportionately likely to smoke, and even though smoking cessation has been linked to improved mood and reduced risk of suicide. This trial enrolls Veteran smokers at high risk for suicide, and assigns them to receive either cessation treatment as usual, or a novel treatment that incorporates standard behavioral cessation treatment with Dialectical Behavior Therapy (DBT), an evidence-based treatment for suicide risk.
NCT06488443
Yoga is a culturally acceptable practice that can reduce craving and help people quit tobacco. There is a need to evaluate the feasibility of implementation of a well- designed yoga protocol to address craving in individuals who use tobacco in India.
NCT04832659
This randomized controlled trial will test whether adding biomarker measurement and informed outreach for tobacco smoke exposure as part of routine practice increases identification and improves treatment, effectiveness, and sustainability of a parental tobacco control intervention that will be integrated into pediatric practice.
NCT04061720
This project will generate knowledge about the effectiveness of Enhanced Chronic Care, an intervention designed to enhance treatment use and smoking abstinence in Veterans who are initially unwilling to quit. Enhanced Chronic Care provides ongoing motivational interventions and interpersonal support designed to promote readiness to quit smoking. Enhanced Chronic Care will be compared with Standard Care (brief advice to quit once per year) on criteria that are of great clinical and public health importance: use of cessation treatment and smoking abstinence. It is expected that Enhanced Chronic Care will increase treatment use and smoking abstinence relative to Standard Care.
NCT05836051
The overarching goal of this translational proposal is to determine if neuroactive flavor chemicals can enhance the addiction potential of electronic nicotine delivery systems (ENDS) by altering brain function and behavior.
NCT05918887
The purpose of the proposed study is to examine the feasibility of integrating a smoking harm reduction program featuring provision of e-cigarettes and tailored instructions to switch into an existing substance use disorder treatment program. This longitudinal study includes three weeks of micro-surveys delivered via text messages to evaluate the intervention's feasibility and acceptability, gather initial effectiveness data, and understand participants' lived experience of smoking and vaping while engaged in substance use disorder treatment.
NCT03625986
The overall goal of this project is to understand the likely health effects of cigarette smokers switching to a Standardized Research Electronic Cigarette (SREC) and to assess the role of nicotine delivery on switching and acceptability as well as markers of health outcomes. Current smokers who meet all eligibility criteria will completely switch from their combustible (regular) cigarettes to an electronic cigarette (SREC) that either contains 58 mg/ml of nicotine or 0 mg/ml of nicotine in the liquid. The investigators' hypothesis is that attempting to switch to a SREC will result in a reduction in markers of harms to health, as compared with the baseline (smoking) measures. The investigators also hypothesize that nicotine-containing SRECs will facilitate switching from smoking more efficiently than zero nicotine SRECs and will result in a significantly greater improvement in markers of health risk, but will result in higher ratings of dependence on the SREC (as compared to the zero nicotine SREC).
NCT06218056
The goal of this research is to evaluate the efficacy of cannabidiol (CBD) in reducing cigarette smoking. Although there are safe and effective treatments for smoking cessation, not everyone who attempts smoking cessation is successful, even with these treatments. Relapse rates are high, leaving a need for new approaches. Despite justification to evaluate CBD for this indication, human research on the topic is scant. Larger, more extended studies are warranted and essential. The investigators will recruit participants from CRI-Help, Inc., a substance abuse treatment program in North Hollywood, where residents who indicate the desire to stop smoking are prohibited from using other cannabis products which would affect recruitment. The aims of this study are: 1. Evaluate the effects of CBD on changes in cigarette use throughout and following the trial. 2. Exploratory Aims. Measure plasma concentrations of CBD, N-arachidonoyl-ethanolamine (anandamide) and 2-arachidonoylglycerol (2-AG) throughout the trial. Participants who meet eligibility criteria will take part in a 56-day treatment phase during which they receive the study medication under supervision (CBD or placebo twice daily) and complete questionnaires on side effects, withdrawal, craving and mood symptoms. Blood, breath, and urine tests will also be performed throughout the study. Participants who complete the treatment will also be assessed at 1-month and 3-month follow up visits.
NCT06651684
Background: The goal of this study is to address parental smoking and social adversity, which can present an obstacle for smoking cessation, in order to decrease childhood exposure to second-hand cigarette smoke. To address these factors, this study includes a smoking cessation intervention for parents and legal guardians recruited in pediatric clinics (CanCEASE), as well as the support of a Health Navigator (HN) to work with the participant towards the resolution or mitigation of unmet social needs. Participants: The research team will recruit one thousand participants from pediatric outpatient clinics within two healthcare centres in and around the city of Montreal, Canada, over the course of 2.5 years. Eligible persons are parents and legal guardians, of any sex and gender, accompanying children under 18 to their scheduled medical appointments, and who report at least one social risk in selected areas (i.e., employment, housing stability, ability to pay for utilities, financial resource strain, food security, transportation, childcare, parent education and health literacy). Participants must also be 18 years old or older with sufficient proficiency in French or English to complete the interviews and questionnaires. In households in which both parents smoke, only one will be eligible to participate, but smoking cessation information will be offered to both. Families presenting at the clinic for an urgent medical issue are not eligible to participate. Intervention: Participants will be divided into control group (care as usual with CanCEASE at the end of the study period) and intervention (CanCEASE + Health navigator). All participants will complete questionnaires at Baseline, 6 and 12 months. The intervention group will receive CanCEASE at the end of each questionnaire. Controls will receive CanCEASE at 12 months. The intervention group will have the possibility to meet with the HNs and will be invited to commit to at least two sessions (i.e.: evaluation and a follow up), with the option to book more time as needed. Aims and hypotheses: Examining how effective the combination of CanCEASE with HN support is in helping parents with unmet social needs quit smoking. Investigators will also examine the effects of the intervention on status of unmet social needs, if the intervention was implemented as planned and well accepted by clinics and participants, and what is the cost of the intervention for each person who quits smoking.
NCT03626064
The PROMPT Pilot Study is a feasibility mixed methods prospective cohort study following principles of community-based participatory action research. The study recruited 80 people who use drugs and followed them for 6 months while providing access to counselling, nicotine replacement therapy and peer-support in a community setting. A notable reduction in average cigarette use per day (20.5 to 9.3) and illicit substance use (18.8%) was observed at study-end. PROMPT's patient engagement model is an effective harm-reduction strategy for the growing opioid use crisis and can improve the health outcomes of marginalised at-risk populations worldwide.
NCT01995123
The purpose of this study is to examine whether behavioral activation as an adjuvant to standard smoking cessation treatment improves smoking cessation outcomes among veterans with PTSD relative to a comparably intense combination of standard smoking cessation treatment + health and smoking education. It is expected that behavioral activation will produce more successful results than health and smoking education when paired with standard smoking cessation treatment.
NCT01928758
The overall aim of this project is to evaluate the effect of progressive nicotine reduction in cigarettes on smoking behavior, toxin exposure and psychiatric symptoms in smokers with comorbid mood and/or anxiety disorders. Smokers with mood and/or anxiety disorder will smoke research cigarettes that will contain either a) nicotine content similar to their preferred usual brand of cigarettes, or b) nicotine content per cigarette that is progressively reduced from approximately 11.6 mg to 0.2 mg per cigarette over 18 weeks. It is our hypothesis that nicotine intake will decline as a function of cigarette nicotine content in the Reduced Nicotine Content group without significant increases in tobacco smoke exposure, severity of nicotine withdrawal symptoms, mood and anxiety symptomatology or protocol non-adherence over time in the Reduced Nicotine Content group as compared with the control group.
NCT02019459
Smokers with serious mental illness including those with schizophrenia and bipolar disorder infrequently attempt and attain sustained smoking abstinence and have a 25-year shorter lifespan due to smoking-related illness. This study will examine whether reducing the nicotine content of cigarettes to non-addicting levels is a viable method of reducing smoking in smokers with serious mental illness. Smokers will be randomized to one of two experimental conditions: 1) very low nicotine content (VLNC) cigarettes or 2) normal nicotine content (NNC) cigarettes. Participants will be assessed for patterns of tobacco use, biomarkers of exposure, subjective responses (e.g., satisfaction, craving, withdrawal symptoms), psychiatric symptoms, cognitive performance, smoking cue reactivity and smoking topography.
NCT01347112
Alcohol dependence is a significant and prevalent public health problem affecting approximately 4% of the U.S. adult population. Individuals with alcohol dependence actively seek treatment annually, and long-term alcohol abstinence varies from 40-60%. Because of the high smoking prevalence and trends toward heavier smoking, alcoholic smokers are at high risk for both morbidity and mortality related to alcohol consumption and tobacco dependence. Although several studies have evaluated pharmacotherapy for tobacco dependence in recovering alcoholic smokers, few have evaluated pharmacotherapy for tobacco dependence among currently drinking alcoholic smokers. Varenicline is the most effective medication currently available for treating tobacco dependence. While some randomized trials have included recovering alcoholics, active alcoholism has been an exclusion criteria for these trials. Thus, this proposal would be the first such clinical trial in currently drinking alcoholic smokers. In addition to helping smokers to stop smoking, varenicline has also been shown to reduce alcohol consumption in rats. The goal of this proposal is to explore the potential efficacy of varenicline for treating tobacco dependence and reducing drinking among alcohol dependent smokers. The investigators hypothesize that 12 weeks of treatment with varenicline, a partial nicotinic acetylcholine receptor agonist will be more effective than placebo in treating tobacco dependence and reducing nicotine withdrawal symptoms in currently drinking alcoholic smokers. The investigators will also explore whether varenicline has an effect on drinking behavior among currently drinking alcoholics. The investigators propose the following specific aims to test these hypotheses in 70 currently drinking alcoholic smokers recruited at the Mayo Clinic in Rochester, Minnesota.
NCT03113370
Almost 12% of women report smoking during pregnancy. Smoking during pregnancy is associated with adverse fetal outcomes and up to 35-75% of women quit smoking during their pregnancy. Clinical trials of tobacco cessation medications have reported safety concerns along with limited efficacy. Subsequently, these medications are not generally recommended in pregnancy and most women who stop smoking do so unassisted. Not surprisingly, the rates of smoking relapse in the post-partum period are up to 67%. To date, clinical trials of behavior interventions in the post-partum period have been largely null. Pharmacotherapy has not been studied as a means of preventing relapse in smokers who quit without the use of medications. Additionally, these medications are excreted in breast milk, which limits there use for lactating women. Thus alternative, safe, and effective strategies to prevent smoking relapse in high-risk, former smokers during the post-partum period are needed. n-3 long-chain polyunsaturated fatty acids (LCPUFA) have anti-inflammatory properties and appear effective as adjuvant therapy for depression. In animal models, n-3 LCPUFA deficiencies can result in hypofunctioning of the dopamine mesocorticolimbic pathways which are related to reward and dependence. Nicotine results in an elevation of dopamine in the nucleus accumbens which is associated with the pleasurable sensations related to nicotine use. It has been hypothesized that correcting the hypofunctioning dopaminergic system through n-3 LCPUFA supplementation might reduce nicotine cravings. Taken together, these studies suggest that supplemental n-3 LCPUFA might be useful in preventing smoking relapse. The investigators' hypothesis is that post-partum former smokers randomized to n-3 LCPUFA supplementation will be less likely to relapse and have less nicotine cravings compared to women allocated to placebo. To test this hypothesis they will conduct a 12-week, randomized, double-blind, placebo controlled study of 4 grams/day n-3 LCPUFA supplementation versus placebo. Participants will be enrolled prior to hospital discharge. The primary outcomes of the trial will be time to smoking relapse and change in self-reported nicotine cravings. The secondary outcome will be point prevalence abstinence at 6- and 12-weeks. compliance will be monitored by measuring red blood cell phospholipid fatty acid content and verify smoking cessation through end-expired CO and cotinine.
NCT00501007
The primary purpose of this investigation is to determine the predictive value of task persistence as measured by a mirror tracing task. A secondary purpose is to evaluate differences in task persistence in smokers with or without schizophrenia. It is hypothesized that task persistence in smokers in both diagnostic categories (schizophrenia and no schizophrenia) will predict tobacco dependence treatment outcome at one and six months. It is also hypothesized that smokers with schizophrenia will show lower levels of task persistence after controlling for other motor skills than smokers without schizophrenia.
NCT00449293
The objective of this pilot research is to investigate the effects of two behavioral smoking cessation programs on aspects of cue-induced cigarette craving, and to further investigate the neural bases of such effects.
