Filter by:This study will help determine if menthol administered by inhalation via electronic cigarettes (e-cigarette) changes the reinforcing effects of pure nicotine administered intravenously in cigarette smokers who smoke mentholated or non-mentholated cigarettes.
In the southwest region of Alaska where the project takes place, 79% of Alaska Native women smoke cigarettes or use smokeless tobacco (ST) during pregnancy. In addition, pregnancy appears to be a high risk period for initiation of tobacco use, primarily ST, among women reporting no use of tobacco 3 months before pregnancy. Intervention efforts targeting the entire community, not only pregnant women, to address social norms about tobacco use may be effective. Thus, the investigators will evaluate the efficacy of a novel, multi-component, theory-based intervention for reducing tobacco use during pregnancy, incorporating both individually targeted and community level components delivered by female elders "Native Sisters." The intervention builds on effective community and individual-based approaches for tobacco cessation and lay health advisor approaches for cancer prevention among Native American women. As part of the intervention, a social marketing campaign including digital stories and other small media will be developed with community feedback. Individually targeted components will be six 30-40 minute telephone or home-based peer counseling sessions with pregnant women.
This study examines the potential effect of reducing nicotine content or menthol or both in women of reproductive age, a vulnerable population identified by the FDA in need of further research.
The purpose of this study is to evaluate atomoxetine's effects on the rewarding and reinforcing effects of nicotine in a controlled human laboratory study with 24 otherwise healthy nicotine dependent subjects. It is hypothesized that atomoxetine will attenuate the negative effects of nicotine.
The purpose of this study is to determine the efficacy, acceptability and unintended consequences of very low nicotine content cigarettes (VLNCC) in smokers with current or past year substance use disorders (SUD). The primary aim of this study is to determine whether 6 weeks of VLNCC compared to normal nicotine content cigarettes (NNCC) will result in more smoking cessation over 6 months and reduce cigarette use, cotinine, and biomarkers of toxicity. We will also assess the effects of VLNCC versus NNCC cigarettes on frequency of substance use and substance cravings (drugs and alcohol) because this is relevant to the safety of these products among smokers with SUD. Secondary aims are to study effects on cigarette craving, nicotine withdrawal and dependence, and depressed mood. Methods: Random assignment to VLNCC versus NNCC of up to 312 smokers with SUD will be balanced by gender, degree of tobacco dependence, and recent drug and alcohol use. All smokers will be provided with smoking counseling. Assessments over 6 months will assess effects both during the 6 weeks of using research cigarettes and after return to usual cigarettes. The importance is in determining the viability and safety of this public health strategy in terms of effects on both smoking and other substance use in a highly addicted population, which is essential to determine before the FDA implements this policy.
The investigators primary hypothesis was that recipients of the Motivational Interviewing intervention would be significantly more likely than those assigned to the Psychoeducation intervention to demonstrate increased readiness to quit smoking at the end of the intervention and to seek smoking cessation treatment in the one month period following the intervention. We also predicted that the Psychoeducation intervention would result in greater improvements in smoking knowledge.
Cigarette smoking is the leading cause of preventable death and disability in the world. Although over 70% of smokers want to quit, fewer than 5% achieve this goal annually. Additional effective, safe, and accessible treatments for nicotine dependence are needed due to the low abstinence rates (20-30%) achieved in behavioral therapies, the unappealing side effects of pharmacotherapy, and the frequent lack of accessibility to treatment. Recent evidence supports the central role of craving in maintaining nicotine dependence, and neither behavioral nor replacement therapies directly target the relationship between cravings and smoking. Mindfulness therapy has been found to be effective in teaching strategies to decouple the association between craving and smoking. Mindfulness based smoking therapy (MT) has preliminary support for reducing consumption in smokers, and Dr. Judson Brewer has recently translated this program into a mobile device application (app) for smoking cessation. With Dr. Brewer's consultation, we propose to assess the feasibility of implementation of a MT mobile application in local hospital and community clinics and the effectiveness of the MT mobile application compared to a National Cancer Institute (NCI) QuitPal behavioral change group. We will examine smoking results at end of treatment and 2 and 6 month follow-up as well as the role of craving. If MT smoking cessation is determined to be effective in a mobile phone application, this finding will be a significant step in providing an additional effective and safe treatment for smokers wishing to quit or cut down on their intake, and will be especially important in providing treatment options for marginalized or hard-to-access individuals wishing to reduce cigarette intake.
Nicotine replacement treatment (NRT) can be efficacious for smoking cessation, but used by only a minority of smokers in China. Pharmacogenetic matching may improve treatment outcomes for NRT in subgroups of smokers. The investigators evaluated the efficacy and safety of sublingual nicotine tablets (SNT) for smoking cessation and the association of catechol-O-methyltransferase (COMT) genotype with efficacy in this smoking cessation trial among Chinese smokers.
In this proposed study with People Living with HIV/AIDS (PLWHA), we will use a stepped care model called a Sequential Multiple Assignment Randomized Trial (SMART) to examine the efficacy of low- and high-intensity smoking cessation treatments for nicotine dependent PLWHA that incorporate the current standard of care and prize-based contingency management. Intervention will be administered in a community-based HIV integrated care clinic in downtown Detroit, which has the highest prevalence rates of HIV/AIDS and smoking in Michigan. Phase 1 will last 4 weeks, and will involve brief intervention to help participants stop smoking. For phase 2, participants will be assigned to different study arms depending on whether they are Responders (reduced their smoking) or Non-responders (continued to smoke). 1. Phase 1: We hypothesize that brief high-magnitude prize contingency management will result in greater reduction in smoking than standard of care alone. 2. Phase 2a: We hypothesize that non-responders who are assigned to contingency management will be more likely to reduce their smoking throughout treatment and to abstain from smoking at all follow-up points. 3. Phase 2b: We hypothesize that responders who are assigned to monitoring and low-magnitude prize contingency management will be more likely to maintain their reduced or abstinent smoking status at all follow-up time-points.
Male and female smokers were recruited to undergo 2 phases of smoking cessation. Each phase was 4 days long and involved 3 brain-imaging scans, blood draws and an intervention involving progesterone or a matched placebo.
