Filter by:The purpose of the study is to obtain two year follow up data for subjects that received six vaccinations of NicVAX in prior phase III studies. No treatment will be administered. Anti-nicotine antibody levels and safety data will be collected.
The purpose of this research study is to examine the effectiveness of an intervention designed to reduce smoking in low income veterans within a regional United States Veterans Administration(VA) health care system. A proactive, personalized, coordinated system of care "Connect to Quit (CTQ)" is rooted in the Chronic Care Model. CTQ treats smoking as a chronic condition, like hypertension or diabetes, that requires long term treatment with appropriate combinations of behavioral therapy and pharmacotherapy. CTQ will be evaluated in the context of three (3) VA Pittsburgh Healthcare System (VAPHS) medical practices.
When smokers are hospitalized they quit smoking, either voluntarily or involuntarily. Most of them, however, go back to smoking soon after discharge. This study will test an innovative approach which includes dispensing nicotine patches at discharge, providing proactive telephone counseling post discharge, or giving a combination of the two. The interventions are aimed at increasing the long term quit rate of these patients. The specific aims of the study are to demonstrate the effects of two interventions, dispensing nicotine patches at discharge and providing proactive telephone counseling soon after discharge, on 12-month quit rates of hospitalized smokers in a 2 x 2 factorial design.
The primary purpose of this study is to test the feasibility of sending pre-cessation nicotine patches and to examine the effects associated with the pre-cessation treatment phase. Specifically, this study aims to: 1. See if subjects will use pre-cessation nicotine patches. 2. See if subjects in the pre-cessation nicotine patches go on to get more nicotine patches. 3. See if pre-cessation treatment with nicotine patches leads to a decrease in number of cigarettes smoked per day. 4. See if sending 2-weeks' worth of patches is helpful to the quitting process.
The aim of this study is to assess the efficacy of varenicline compared to placebo in tobacco dependent individuals who are undergoing concurrent treatment for alcohol dependence. As they will be inpatients and under 24 hour medical care for the first 21 days of treatment, or receiving outpatient treatment through the Alcohol Research and Treatment Clinic, this will allow for a comprehensive assessment of the safety of varenicline in this population with minimal risk of adverse consequences. The patients will continue their cessation treatment for an additional 10 weeks as outpatients through the Nicotine Dependence Clinic at CAMH. They will also be contacted at 6 months for follow-up.
This study is designed to gather preliminary effectiveness and safety data on the use of bupropion for smoking cessation in pregnant women attending a community prenatal clinic. This study will provide critical preliminary data in preparation for a larger, Phase III clinical trial.
This project will be a randomized clinical trial testing the efficacy of an internet-administered smoking cessation treatment for overweight and obese smokers. Research on internet-administered behavioral treatments for smoking cessation has found that compared to control treatments (e.g., self-help materials), cessation rates in internet-administered treatments are significantly higher. Research testing the applicability of these treatments to overweight and obese individuals has not yet been conducted. Given that a substantial portion of smokers are also overweight and at elevated cardiovascular risk, there is a need for directed treatment efforts for this group. The current trial proposes to be the first to test the effectiveness of internet-administered smoking cessation treatment for overweight and obese (BMI≥25) smokers. Adult participants will be randomized to receive 12 weeks of internet-administered treatment consisting of either: a) standard smoking cessation treatment with general health education, or b) standard smoking cessation treatment with cognitive behavioral therapy (CBT) for weight concerns. Participants in both conditions will receive open-label treatment with the 21 mg transdermal nicotine patch.
This study recruited cigarette smokers under supervision in community corrections (e.g., probation, parole, drug courts, etc.) in the Birmingham, Alabama area. Smokers received 12 weeks of bupropion treatment and brief physician advice to quit smoking or 12 weeks of bupropion treatment and 4 sessions of intensive counseling around smoking cessation. The study was stratified on race such that equal proportions of African Americans and Caucasians were enrolled in the two study groups. It was hypothesized that smokers receiving intensive counseling will have higher quit rates compared to smokers receiving brief advice to quit.
The aim of this study is to determine if using a behavioural replacement for smoking (de-nicotinised cigarettes; DNCs), in addition to standard treatment during the first two weeks after the target quit date, can reduce urges to smoke over the first 4-weeks of abstinence. Two hundred smokers who want to quit will be recruited from the community. They would all receive standard smoking cessation treatment from the NHS Stop Smoking Service (NHS SSS), which uses a combination of stop smoking medication (e.g. nicotine replacement therapy, Champix) and motivational support. On their target quit date, participants would be randomised to receive behavioural replacement ( i.e. use of de-nicotinised cigarettes) plus standard treatment for the first two weeks of their quit attempt, or to continue with standard treatment alone. De-nicotinised cigarettes are similar to standard cigarettes except that they do not deliver nicotine to the smoker. Participants will rate their urges to smoke at each week. Standard NHS SSS measures will also be taken in addition to user acceptability ratings and reactions to smoking cues. The hypothesis is that complementing current NHS SSS treatments with de-nicotinised cigarettes, to address the non-nicotine factors associated with smoking and to help extinguish smoking behaviour, would result in lower urges to smoke than standard treatment alone.
In an open label, randomized, two-way cross-over study, 32 male healthy regular snus users will be given repeated doses of four different types of portion snus: "General", "Catch", "Catch Mini" and "Catch Dry Mini". Each portion of used snus will be collected and frozen (-20 oC) pending analysis of lead (Pb), cadmium (Cd), nicotine and tobacco specific nitrosamines (TSNAs). Unused snus is collected and deep frozen for analysis and calculation of extracted dose. Calculations of extracted amount of lead, cadmium, nicotine and tobacco specific nitrosamines (TSNAs) respectively, will be done for each type of snus.
