Active clinical trials for "Tobacco Use Disorder"

Participants will be smokers who want to quit, and have visible nicotine stains on their teeth. They will be given toothpaste and a toothbrush to use during the study, and will have an equal chance of being assigned to use either a nicotine gum or microtab. They will visit the study site five times during the 12 week trial to have their teeth examined.

Background: The prevalence of cigarette smoking among individuals with schizophrenia is noticeably higher than in the general population, and smoking cessation attempts frequently are unsuccessful in this population. Little is known about the effects of cigarette/nicotine craving in individuals with schizophrenia. Researchers are interested in learning more about how craving affects people with schizophrenia and developing new ways to treat cravings and improve the effectiveness of smoking cessation therapies and treatments. In recent years, virtual reality (VR) has been studied to determine whether it can be used to induce craving by using life-like cue settings. VR cues involving cigarette use, including images of cigarettes and scent cues of tobacco smoke, may be used to elicit craving in smokers. Researchers are interested in learning more about how individuals with schizophrenia respond to specific VR cues and settings. Objectives: To determine the feasibility of using a contextual real-world paradigm using virtual reality involving cigarette smoking in people with schizophrenia. To examine if virtual reality cues will elicit craving in smokers with schizophrenia. Eligibility: - Current smokers (five or more cigarettes per day for at least 1 year) between 18 and 45 years of age who have been diagnosed with schizophrenia/schizoaffective disorder. Design: The study will involve three sessions, with an initial screening visit, a test session, and a follow-up session. Screening visit: Participants will be screened with a medical and psychiatric history, and will answer questions about smoking history, current smoking habits and craving patterns, and general anxiety levels. This session will also introduce participants to the operation and use of the VR equipment. Participants who are comfortable using the VR system will return within 2 days for the test session. Test session: Participants will use the VR equipment to view neutral scenes and scenes that are designed to elicit cravings for cigarettes. After viewing each scene, participants will answer questions about their overall mood, anxiety levels, and any cigarette cravings they may have. Follow-up session: Participants will return 1 week after the VR session to answer questions about mood, anxiety levels, and current smoking habits and craving patterns.

QuitAdvisorMD: A point-of-care tool for brief smoking cessation interventions Under a Phase II SBIR grant supported by NIH/NIDA, we are developing QUITAdvisorMD: a point-of-care, patient-centered resource for counseling patients who smoke or use tobacco products. It is based on the principles of Motivational Interviewing, a non-confrontational and very effective method for intervening and treating these patients; the 5 A's of behavioral interventions; and the Transtheoretical Model of Change. Through a point and click interface, the tool uses a series of interview questions designed to motivate patients to stop smoking by first assessing their stage of change and then offering effective stage-based interventions and interview techniques. The tool also offers stage-tailored patient information, a clinician educational reference, and the ability to communicate support information patients via email and/or text message.

This research project addresses the hypothesis that a neurocognitive profile characterized by impairment of response inhibition and sustained attention may be a risk factor for smoking initiation and nicotine dependence among young women. Nicotine has short- term, facilitating effects on attention and response inhibition. Therefore, individuals who are impaired on cognitive functions such as these and initiate cigarette smoking may be more likely to maintain the habit and develop nicotine dependence. The research protocol specifically tests whether administration of nicotine to non-abstinent, regular cigarette smokers improves cognitive function in those domains where the participants had previously been shown to manifest performance deficits

This is a three year follow up of a previous study where researchers at UNSW and UNewc asked smokers with serious mental health problems to participate in a 12-month study, to assess whether intervention could assist people experiencing mental illness reduce their tobacco smoking.

Smoking during pregnancy is the single most preventable cause of illness and death among mothers and infants. Because of the stigma associated with tobacco use during pregnancy, pregnant women are less likely to disclose their smoking status to doctors or study researchers. This study will evaluate the use of a new biomarker of nicotine metabolism to estimate tobacco use in a group of pregnant women who participated in the New England Smoking Cessation and Reduction in Pregnancy Trial (SCRIPT).

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 link between tobacco smoke carcinogen biomarkers and the risk of developing lung cancer.

Michigan has the 10th highest smoking rate in the nation. Smoking rates are also very high in the Middle East and in Arab American families. The purpose of this study is to learn about tobacco use in Michigan Arab American youth ages 14 to 18. The study will evaluate why some young people start smoking and others do not. The study will also test an educational program designed to encourage young people to either quit tobacco use or to avoid it.

The study is a randomized crossover trial. Current menthol smokers will complete a session with each flavor of an electronic cigarette: menthol and tobacco. The objective of this survey is to assess for flavor preference.
