Active clinical trials for "Tobacco Use Disorder"

The purpose of the overall parent study is to determine the impact of gender and hormones (estradiol, progesterone, testosterone and cortisol) on responses to stress and smoking cues presented in daily, "real-world" cue presentations compared to a final cue session in a lab. In addition, in the portion of the study that incorporates clinical trials elements and is reported here, the study will examine the impact of a single dose of oxytocin (chemical produced in the body) versus placebo (inactive substance) on reactivity to a stress procedure (Trier Social Stress Task) in smokers. The overall parent study involves a cue presentation technology known as "CREMA" (Cue Reactivity Ecologic Momentary Assessment) which delivers four daily cue presentations to you on a handheld device during your everyday routine. Additionally, the study involves daily collection of saliva samples for hormonal testing. These daily procedures will provide information about the role of cues and hormones in daily life. The clinical trial portion of the study (reported here) consists of measures collected within the laboratory.

The primary goal of this study is to use qualitative interviews and focus groups to aid us in adapting a face-to-face smoking cessation intervention for delivery through text messaging. After design is completed, the intervention will be pilot tested with a sample of young adults (ages 18-35) who smoke. Final assessments will be conducted at 7 weeks (end of treatment) and both 3 and 6 month follow up.

The proposed project will utilize perfusion functional magnetic resonance imaging (fMRI), a functional candidate gene association approach (of dopaminergic addictions-targeted polymorphisms), and the dopamine-modulating and gamma-aminobutyric acid (GABA) B receptor agonist, baclofen, to examine the brain and behavioral responses in smokers to appetitive smoking reminders (cues that motivate continued smoking and relapse). These studies will provide a means to identify an appetitive cue-sensitive pharmacologic-responsive endophenotype. Once brain/behavioral/genetic endophenotypes can be determined prior to treatment, smoking cessation treatments can be structured to meet individual needs, which will significantly improve treatment outcome.

The purpose of this study is to evaluate the impact of varenicline treatment on cue induced craving to smoking using brain imaging. The investigators hypothesize that participants will report reduced urges to smoke and will have less activation in parts of the brain associated with craving.

The overall goals of this line of research are to develop and evaluate innovative treatments for lesbian, gay, bisexual, and transgender (LGBT) cigarette smokers and to understand the processes related to smoking and relapse in this previously unstudied population of smokers. In this study, participants are randomly assigned to one of two Internet-based smoking cessation treatments: 1) a self-help intervention tailored LGBT smokers plus social support plus email-based counseling, or 2) a standard self-help condition alone, similar to other general smoking cessation treatments. Before starting the program, participants will complete measures of smoking, nicotine dependence, depression diagnosis, demographics, mood, motivation to change, and alcohol use. Smoking status will be determined at 1, 3, 6, and 12 months following the start of treatment. Data will be analyzed to compare the quit rates of the two Internet-based treatment groups. Also, we will complete exploratory analyses to determine those variables that best predict quitting for LGBT smokers.

The primary objective of this study is to determine which is the better approach to smoking cessation in veterans: bupropion combined with transdermal nicotine or high dose nicotine replacement therapy (NRT) using transdermal nicotine combined with nicotine inhaler.

The novel and exploratory nature of this intervention relates to the concept of incorporating patient-specific oral health information obtained during a dental hygiene visit into the tobacco quitline counseling. Linking the patient-specific oral health information obtained during the dental hygiene visit to the tobacco quitline counseling will close the therapeutic loop for oral health professionals and make them a focal point for the tobacco use intervention without increasing clinical burden.

Health care systems are key channels for delivering tobacco cessation treatment to the smokers in a population. A population-based approach could complement office-based care and offload busy clinicians. The project will conduct population-based proactive outreach to current smokers in a health care system's primary care practices and randomize smokers who respond to the outreach to 3 groups: 2 alternative evidence-based cessation resources or to usual care. Specific Aims: Aim 1: To determine the feasibility and reach of the program Aim 2a: To determine whether the 2 intervention arms combined increase the proportion of smokers who use tobacco cessation treatment over a 6-month follow-up compared to those randomized to usual clinical care. Aim 2b: To determine whether each of the two intervention arms increases the proportion of smokers who use tobacco cessation treatment over a 6-month follow-up, compared to those receiving usual clinical care.

The 2-year research plan will test the Extended Put It Out Project (POP-6) in a pilot randomized trial (N=168) compared to TSP-6, as well as comparing POP-6 and TSP-6 to the POP-3 and TSP-3 interventions from a previously-conducted trial. Participants will be young adults who smoke, identify as sexual or gender minorities (SGM), and use Facebook. Primary outcome will be biochemically verified 7-day abstinence from smoking at 3 and 6 months. Secondary outcomes will be a quit attempt (y/n), stage of change, and thoughts about tobacco abstinence at 3 and 6 months.

The objective of this research is to determine whether smartphone games show promise for helping smokers increase their chances of quitting. The central hypothesis is that smokers who have access to smartphone games during their quit smoking attempt will smoke fewer cigarettes and report less craving than will smokers without such access.
