Filter by:The investigators propose an innovative full-factorial design in a cohort of 1056 adult smokers in an urban emergency department (ED), to test the efficacy of four key intervention components: motivational interviewing, medication, quitline referral, and texting. At the trial's completion, a mixed-methods approach will be used to identify the components that were efficacious within the proposed cost constraint, along with feasibility and acceptability to providers and subjects. The investigators will then assemble an intervention that maximizes efficacy, given a cost-effectiveness constraint and findings from a qualitative analysis.
The purpose of this study is to determine whether the abuse liability of cigarettes with altered composition (cigarettes differing in composition; e.g., tar levels, amount of sugar, casings) is reduced relative to standard composition cigarettes.
Three hundred-twenty (320) adult smokers of menthol or non-menthol combustible cigarettes will be recruited and randomly assigned to one of five groups (n=64/group), who will be asked to switch for 12 weeks to ad libitum use of combustible cigarettes (matched to subjects' menthol preference) containing either 0.4, 1.4, 2.5, 5.6 or 16.9 mg nicotine (standardized nicotine yields ranging from 0.02-0.80 mg/cigarette), respectively. Each group will include 32 heavy (≥ 20 cigarettes/day), and 32 light smokers (≤10 cigarettes/day), who are hypothesized to be more sensitive to nicotine's reinforcing effects. Participants will also have free access to nicotine-containing e-cigarettes (JUUL) throughout the 12-week period. Abuse liability of combustible cigarettes will be assessed by behavioral (cigarettes/day, time to first cigarettes), self-report (rewarding effects, withdrawal symptoms) and biochemical indices (expired air carbon monoxide, cotinine blood sampling). In laboratory sessions, we will measure nicotine thresholds for detecting and recognizing the addictive, rewarding effects of smoking. This study is designed to help the FDA identify a target nicotine threshold that will not attract young people to smoking or induce relapse in former smokers. Additionally, we will determine the level of cigarette nicotine reduction that will be tolerated without inducing dissatisfaction in smokers, information that is relevant to the FDA for designing a stepwise nicotine reduction policy that can be implemented without widespread objections. The knowledge gained from this project will greatly increase our knowledge of nicotine addiction and will help frame an FDA policy relating to the regulation of the nicotine content of tobacco. Ultimately, a well-designed nicotine reduction policy has the potential to greatly reduce the enormous toll of death and disease caused by cigarette smoking.
The purpose of this study is to evaluate the effect of 10 sessions of anodal transcranial Direct Current Stimulation (tDCS - 1 mA) applied to left vs right CDLPF of tobacco-dependent subjects compared to the application of a placebo tDCS (sham procedure) on the craving, which is evaluated by the item 1 of Fagerström test between day 1 and day 10. Craving is also evaluated 1 month post-treatment.
Despite an overall reduction in US smoking rates from >50% in the 1960s to about 20% by 2000, the rate of smoking among persons with a serious mental illness (SMI) remains 2-3 times greater than in the general population. Further, even the recent small decline in smoking rates that has been reported in the general population in the past decade has not occurred among smokers with an SMI. In fact, 44% of all the cigarettes consumed in the US are by individuals with a psychiatric disorder and the primary cause of death among Americans with an SMI is a tobacco-related disease. This cluster randomized trial will be conducted in 14 Philadelphia community mental health clinics (CMHCs). Clinics will be randomized to either Addressing Tobacco Through Organizational Change model (ATTOC) or Usual Care (UC) treatment groups. The investigators hypothesize that 1) at the end of the intervention and at a 3-month follow-up, rates of adherence to guidelines for treating TUD will be greater among clinic personnel that receive the ATTOC intervention vs. clinic personnel in usual care; 2) at the end of the intervention and at a 3-month follow-up, rates of client smoking cessation will be significantly greater in clinics that receive the ATTOC intervention than among clients treated with usual care; and 3) using non-inferiority testing, at the end of the intervention and at a 3-month follow-up, there will be no significant degradation in mental health functioning or QOL among clients who receive care at clinics that received the ATTOC intervention than among clients treated with usual care.
The purpose of this study is to conduct an observational assessment of natural outcomes within the Duke Smoking Cessation Program (DSCP), "Quit at Duke." This assessment will include information regarding abstinence rates, changes in patient emotional state following treatment, and costs of operations. Primarily, this study will assess the financial sustainability and the cost-effectiveness of the program.
This study is designed to test the effectiveness of the smoking cessation intervention "Sit to Quit" through a randomized-control trial. This study will compare abstinence outcomes in the Sit to Quit study group to a control group using the North Carolina State Tobacco Quit Line.
The purpose of this project is to build capacity for quality improvement (QI) in small primary care practices across Washington, Oregon and Idaho by improving risk factors for heart attacks such as blood pressure, cholesterol and smoking. The Northwest Coalition for Primary Care Practice Support will assist practices by providing them with a QI coach, creating group learning opportunities, and conducting educational outreach activities. An innovative study design will be used to determine what levels and types of support are most helpful and effective.
This study will examine how abstinence-induced brain changes contribute to smoking cessation outcomes in treatment-seeking smokers.
The purpose of this study is to determine whether combining noninvasive brain stimulation with cognitive training can reduce craving in adults with tobacco use disorder.
