Filter by:The proposed work will advance the understanding and effectiveness of tobacco dependence treatment and result in more smokers quitting successfully.
In the current proposal, we intend to study the efficacy of bupropion SR with or without combined contingency management (CM) among adolescent cigarette smokers. The proposed study will test not only medication (bupropion SR), but also combination of medication and CM in potentially improving smoking cessation outcomes AND retention of adolescent smokers in the study. Hypothesis to be tested: Bupropion SR treatment will increase abstinence from cigarette smoking (as measured by urine cotinine and continuous abstinence) in adolescent smokers as compared to treatment with placebo only. Hypothesis to be tested: Adolescent smokers treated with combined bupropion SR + contingency management (CM) treatment will have increased retention and increased abstinence rates when compared to bupropion SR alone or CM + placebo treated groups (as measured by decreased drop-out of participants, urine cotinine and continuous abstinence). Hypothesis to be tested: CM will increase the abstinence from cigarette smoking (as measured by urine cotinine and continuous abstinence) in adolescent smokers as compared to treatment with placebo only.
Background. The ROSCAP Study was a randomized controlled trial in heart disease patients to test the effect of a smoking reduction intervention on cigarettes per day (cpd) and biochemical and clinical indicators of tobacco exposure. .
The study is designed to evaluate and compare the efficacy and cost effectiveness of 3 smoking cessation treatments with HIV-positive cigarette smokers. The treatments include face-to-face individual counseling, a computer-Internet-based self-help treatment and a self-help manual treatment.
Smoking while on nicotine patches will help subjects to reduce their expired carbon monoxide levels from the levels they were before they started using the patch. Subjects will also decrease their daily consumption of cigarettes.
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.
Craving and withdrawal from smoking cigarettes are major factors for relapse. We investigated craving for cigarettes in smokers undergoing pharmacological treatment with Bupropion (Zyban). We compare cue-induced reactivity to smoking videos in smokers who were successfully treated with Bupropion to smokers who are still smoking. We measured the brain's metabolic activity in response to smoking and neutral cues in Positron Emission Tomography using FDG.
This is a 2-year study involving the progressive reduction in the nicotine content of cigarettes. The investigators believe that at the end of the study smokers of cigarettes with progressively reduced nicotine content will be "weaned" from nicotine. At the end of the study, the result will be a decreased level of nicotine dependence. When smokers are again free to choose any smoking behavior, they will smoke fewer cigarettes and/or have a greater interest in quitting compared to a control group that smokes their usual cigarettes.
The purpose of this study is to evaluate the efficacy of the glycine antagonist, GW468816, compared with placebo on duration of abstinence and rates of relapse in recently quit female smokers in a randomized, double-blind, five-week clinical trial. According to the investigators, the new medication, GW468816, is thought to send certain signals in the brain that may be effective in helping people stay abstinent after they have recently quit smoking. GW468816 is a non-nicotine drug. The investigators of this study hypothesize that subjects receiving GW468816 will demonstrate a significantly longer time to relapse to smoking than those in the placebo group, as measured by the primary outcome measure (see below).
Since 1996, the nicotine patch has been re-classified from prescription to over-the-counter (OTC) status in the United States. Little is known about how the public uses the OTC nicotine patch due to lack of monitoring. The purpose of this observational study is to describe the characteristics of consumers who purchase OTC nicotine patches from community pharmacies and to determine the factors associated with the appropriate use of nicotine patches.
