Filter by:The research is based on a chronic disorder model of cigarette smoking which suggests that long-term treatment targeted to prevent relapse may be useful. Based on this model, the investigators have developed a relapse prevention treatment to intervene on five areas important in relapse prevention, including fluctuating motivation, depression, withdrawal, weight gain, and social support. This treatment protocol has produced high long-term abstinence rates when implemented in a clinical research setting. The current study will evaluate the treatment model when implemented in a medical outpatient setting.
Background: - Multiple social, psychological, and environmental factors contribute to adolescents' use of cigarettes. Environmental smoking cues have been shown to play an important role in the maintenance of nicotine addiction and in relapse to smoking. However, few studies have examined craving and cue-reactivity in adolescent smokers, even though craving appears to contribute to ongoing smoking and relapse in this age group. - Another factor central to addiction is the rewarding effect of drugs, or the interaction between the person, the drug, and the environmental setting. However, more research is needed on whether environmental cues lead to increased smoking in adolescents. Objectives: - To determine the effects of smoking versus neutral cues in adolescents who smoke on (1) craving, mood, and autonomic responsivity and (2) the relative reinforcing efficacy of tobacco cigarettes. Eligibility: - Adolescents 12 to 17 years of age who are current smokers (at least five cigarettes per day for the past 6 months). Design: - This study will involve three study visits. Participants will be allowed to smoke before all study sessions and will give a breath carbon monoxide (CO) sample before all sessions. Participants must not use any illicit drugs or alcohol 24 hours before sessions. - Visit 1 (baseline session): Participants will provide a urine sample and will be familiarized with the study room and session design. - Visits 2 and 3: Participants will be connected to physiological recording devices to measure heart rate, perspiration, and other physical responses. After baseline readings, participants will be exposed to smoking cues at one experimental session and to neutral cues at the other experimental session. - Before, during, and after cue presentation, participants will complete self-report measures of mood and craving and have physiological measures taken. They will then be re-exposed to smoking or neutral cues and engage in a self-administration procedure to examine the effect of cues on the reinforcing efficacy of cigarettes.
The purpose of this study is to assess the effects of mindfulness training (MT) compared to standard Smoking Cessation Therapy (SCT) on smoking cessation and stress provocation in individuals trying to quit smoking.
The Smoking Termination Opportunity for inPatients, (STOP) project is designed to capture the opportunity that is provided by admission for acute smoking related illness, to assist patients through withdrawal by use of a combination of: - the new medication Champix with - best practice counselling - initiated in an inpatient setting to achieve: - sustained smoking abstinence - reduced hospital bed and health service utilisation - reduced inpatient smoking and craving prior to discharge
Background: - Smoking is the leading cause of preventable death in the United States, and researchers are interested in gaining a better understanding of the perceived beneficial effects of nicotine to help improve treatment strategies for nicotine dependence. Understanding the conditions under which nicotine improves attention and cognitive processing may provide more useful information for this research. - The ability to pay attention and filter relevant from irrelevant stimuli is central to all aspects of information-processing. Top-down and bottom-up attentional processes illustrate how the brain combines stimuli and goal-directed behaviors. Bottom-up processing is an unconscious response to sensory input; for instance, when the eyes automatically focus on a prominent image in a picture. Top-down processing is a conscious response to drive attention toward specific stimuli; for instance, when a person is asked to focus on a less immediately noticeable image in a picture. Researchers are interested in determining whether nicotine improves cognitive performance by acting on top-down or bottom-up attentional mechanisms. Objectives: - To investigate the effect of nicotine on the top-down and bottom-up mechanisms of attention in cigarette smokers. Eligibility: - Current smokers (at least 10 cigarettes per day for at least 1 year) between 18 and 55 years of age. Design: - This study will involve one training session and four experimental sessions. - During the training session, participants will receive a sample dose of the nicotine nasal spray used in the study to determine if they can tolerate the effects. - For each experimental session, participants will receive one dose of nicotine nasal spray (1 mg, 2 mg, or 3 mg) or placebo spray, followed by blood pressure and heart rate monitoring, performance of an attentional test, and questionnaires to rate participants perception of nicotine effectiveness. Participants may receive different doses at different sessions, and will not be told which dose they will receive at any given point.
At any given point in time, most smokers are not interested in making a serious quit attempt. Data suggest that 30% of smokers have no plans to quit, 30% plan to quit at some future date, 30% plan to quit in the next 6 months, and about 10% plan to quit in the next month. While ~40% of smokers make a quit attempt each year, only about 4-6% of those achieve long-term success. This means that of the more than 60 million Americans who smoke, only 1 million are able to quit each year. If we could double the number of quit attempts and maintain comparable success rates, we could double the number of individuals who will benefit from living smoke free lives. These observations underscore the need to develop interventions that increase smokers' motivation or willingness to make quit attempts, and that also increase the rate of success among those who attempt to quit. The overall goal of this proposed experiment is to identify effective interventions aimed at increasing motivation for smoking cessation, increasing quit attempts, and increasing rates of cessation success. Interventions that will be tested include: use of nicotine gum, use of nicotine patches, motivational interviewing, and smoking reduction counseling. At minimum, all participants will complete surveys about their smoking behavior that might increase their motivation to eventually quitting smoking.
The goal of this study is to train phone counselors working for the New York (NY) State Smokers' Quitline to advise callers who drink at hazardous levels to limit or abstain from alcohol use to determine whether this improves smoking cessation outcomes so that we can establish effect size estimates for a full scale multi-site trial.
This study, based in India, is testing the efficacy of varenicline to help smokeless tobacco users with cessation efforts.
The goal of this proposal is to explore the potential effectiveness of varenicline to treat tobacco dependence among recovering alcoholic smokers who, as a group, are at high risk for tobacco-caused morbidity and mortality. In this open-label phase II clinical trial, we are proposing to enroll 32 recovering alcoholic smokers who are motivated to stop smoking. After the initial up titration of varenicline in week 1, all 32 subjects will receive a total of 2 mg/day of varenicline for 12 weeks. In addition to receiving varenicline, all subjects will receive brief behavioral counseling and our standard intervention at each visit during participation in the study.
Nicotine dependence is very common among Asian Americans; yet, research on understanding and treating nicotine dependence in this group is almost nonexistent. The proposed study is a first attempt to develop a smoking cessation program that is tailored to Korean-culture specific aspects. It is proposed that Korean Americans who receive a culturally tailored smoking cessation program will be more likely to have prolonged abstinence at 12-month follow-up than their counterparts who receive brief cessation counseling. Subjects in both arms receive nicotine patches for 8 weeks. Self-reported abstinence is validated with exhaled carbon monoxide and salivary cotinine tests.
