Filter by: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
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.
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.
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.
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.
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.
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.

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.
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.
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.
