Active clinical trials for "Tobacco Use Disorder"

The goals of this within-subject pilot study are: (1) assess the feasibility and safety of administering the Catechol-O-Methyl-Transferase (COMT) inhibitor, tolcapone, to smokers, and (2) explore whether tolcapone may reduce abstinence-induced cognitive and affective symptoms that promote relapse. A secondary exploratory goal is to assess whether these effects may be more pronounced in smokers who carry a high risk COMT genotype for smoking relapse: COMT val/val.

The purpose of this study is to 1) evaluate the safety and efficacy of two doses of bupropion SR (150mg/day and 300mg/day) when compared to placebo, as an aid to smoking cessation in adolescents and 2) to examine which factors, such as medication adherence, nicotine dependence, and motivation to quit, affect treatment outcome.

The information gathered in this study may help to develop more effective ways to help people quit smoking and stay quit in the future.

The purpose of this study is to assess the safety and feasibility of concurrent treatment of nicotine dependence (cigarette smoking) and acute depression. Participants who meet DSM-IV criteria for both nicotine dependence and acute major depression will be given pharmacological treatment for both disorders at the same time, along with a brief behavioral intervention for smoking cessation.

Women typically have a more difficult time quitting smoking than men. Little research has been done to understand the differences between men and women that may cause this distinction. This study will assess whether the reduced effectiveness of nicotine replacement therapy in women is caused by gender differences in the withdrawal suppression induced by nicotine replacement therapy.

Nicotine addiction is a serious health problem in the United States; 46 million people smoke cigarettes, and 70% of those are trying to quit. The nicotine patch and bupropion, a medication used to reduce nicotine cravings, are two commonly used smoking cessation aids. Both have been shown to reduce smoking rates, however, the effectiveness of combining the two treatments has not been widely examined. This study will evaluate the effectiveness of the nicotine patch combined with bupropion at reducing smoking rates among younger, low-income, and minority individuals.

Currently one in five high school students smoke. Smoking can harm adolescents well before they reach adulthood by causing a number of immediate, sometimes irreversible, health risks and problems. This study will examine whether reducing smoking will facilitate quitting smoking in adolescents who have unsuccessfully attempted to quit smoking

The purpose of this study is to test in a randomized clinical trial a series of hypotheses concerning the efficacy of an extended expert-system intervention plus nicotine replacement therapy (NRT) for treating tobacco dependence among patients hospitalized on a smoke-free psychiatric unit.

The purpose of this study is to determine the efficacy and cost-effectiveness of long-term pharmacotherapy (using Zyban and/or nicotine replacement) for reducing the relapse rate associated with stopping smoking.

Treatment studies have demonstrated that current smoking cessation techniques are less effective for women. The purpose of this study is to determine the role that gender plays on the effectiveness of nicotine replacement therapy. This may lead to improved cessation interventions for all smokers, particularly women.
