NCT ID: NCT00158158 Completed - Smoking Cessation Clinical Trials

Effectiveness of Reducing Smoking in Facilitating Smoking Cessation in Adolescents - 2

Start date: September 2005
Phase: Phase 2/Phase 3
Study type: Interventional

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

NCT ID: NCT00158145 Completed - Clinical trials for Tobacco Use Disorder

Assessing the Variability Over Time of Tobacco Carcinogen Biomarkers in Smokers - 2

Start date: September 2005
Phase: Phase 2
Study type: Observational

Lung cancer is the leading cause of cancer death in the United States. Currently it remains impossible to predict which smokers will get cancer. Each puff of a cigarette delivers a mixture of over 60 known carcinogens. Biomarkers that quantify carcinogen levels and metabolism are a useful tool and available to use. The purpose of this study is to assess the variability of tobacco smoke carcinogen biomarker levels over one year in a group of smokers.

NCT ID: NCT00142831 Completed - Clinical trials for Tobacco Use Disorder

Bupropion as an Adjunct to the Nicotine Patch Plus CBT

Start date: April 1999
Phase: Phase 4
Study type: Interventional

Existing and new pharmacotherapies along with prevention efforts are key to improving smoking cessation rates and reducing the premature morbidity and mortality associated with tobacco use. A number of individuals suffer from both nicotine dependence and depression. The purpose of this study is to determine the effectiveness of bupropion used in combination with the nicotine replacement patch and cognitive behavior therapy (CBT) in treating nicotine dependent individuals also diagnosed with depression.

NCT ID: NCT00136838 Completed - Clinical trials for Tobacco Use Disorder

Effect of Smoking Exposure on Smoking Relapse Following Brief Abstinence - 2

Start date: October 2001
Phase: N/A
Study type: Interventional

Recent research on the effects of nicotine on the brain and behavior presents an opportunity to advance medication development. The purpose of this study is to develop a laboratory model for early-stage testing of new and existing treatments for nicotine addiction. Specifically, the investigators will develop a laboratory model of relapse to cigarette use in nicotine dependent volunteers.

NCT ID: NCT00136812 Completed - Clinical trials for Tobacco Use Disorder

Treating Tobacco Dependence in Inpatient Psychiatry - 1

Start date: July 2006
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT00136786 Completed - Clinical trials for Tobacco Use Disorder

Effect of Memantine Versus Bupropion on Smoking Relapse in Nicotine-Dependent Individuals - 3

Start date: December 2006
Phase: Phase 1
Study type: Interventional

One of nicotine's effects on the body is at the level of the NMDA receptors in the brain. Memantine is a drug that also affects NMDA receptors, making it a candidate for the treatment of nicotine addiction. The purpose of this study is to evaluate the effectiveness of memantine using a laboratory model of smoking relapse in nicotine dependent volunteers. Investigators will compare the effects of memantine with bupropion, medication currently used to facilitate smoking cessation.

NCT ID: NCT00136760 Completed - Clinical trials for Tobacco Use Disorder

Contingent Incentives Plus Bupropion for Smoking in People With Schizophrenia

Start date: September 2003
Phase: Phase 2
Study type: Interventional

There is a high prevalence of smoking among people with schizophrenia, and there are few smoking treatment programs for these smokers. The aims of this study are to investigate the separate and combined effects of bupropion and a voucher incentive program on smoking in people with schizophrenia.

NCT ID: NCT00136747 Completed - Clinical trials for Tobacco Use Disorder

The Effects of Memantine and Bupropion on Acute, Reinforcing, and Conditioned Effects of Cigarettes - 1

Start date: January 2004
Phase: Phase 1
Study type: Interventional

One of nicotine's effects on the body is at the level of the NMDA receptors in the brain. Memantine is a drug that also affects NMDA receptors, making it a candidate for the treatment of nicotine addiction. The purpose of this study is to evaluate the effectiveness of memantine using a laboratory model of tobacco addiction. The investigators will compare the effects of memantine with bupropion, medication currently used to facilitate smoking cessation.

NCT ID: NCT00135772 Completed - Clinical trials for Tobacco Use Disorder

Nicotine and Cotinine Levels in Smokers With Schizophrenia and Schizoaffective Disorder - 2

Start date: October 2003
Phase: N/A
Study type: Observational

Nicotine dependence is very common among individuals with schizophrenia and schizoaffective disorder. Cotinine is a chemical that is made by the body from nicotine. Measuring levels of nicotine and cotinine is an accurate way to determine how much cigarette smoke enters a person's body. The purpose of this study is to measure nicotine and cotinine levels in smokers with schizophrenia or schizoaffective disorder to determine if such individuals absorb more nicotine per cigarette than smokers without schizophrenia-related disorders.

NCT ID: NCT00135746 Completed - Clinical trials for Tobacco Use Disorder

Examining the Effectiveness of the Nicotine Patch in Male and Female Smokers - 2

Start date: May 2004
Phase: N/A
Study type: Interventional

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.
