Active clinical trials for "Tobacco Use Disorder"

The purpose of the study is to compare two different dosage forms from which nicotine is released and absorbed into the bloodstream.

Despite an overall reduction in US smoking rates from >50% in the 1960s to about 20% by 2000, the rate of smoking among persons with a serious mental illness (SMI) remains 2-3 times greater than in the general population. Further, even the recent small decline in smoking rates that has been reported in the general population in the past decade has not occurred among smokers with an SMI. In fact, 44% of all the cigarettes consumed in the US are by individuals with a psychiatric disorder and the primary cause of death among Americans with an SMI is a tobacco-related disease. This cluster randomized trial will be conducted in 14 Philadelphia community mental health clinics (CMHCs). Clinics will be randomized to either Addressing Tobacco Through Organizational Change model (ATTOC) or Usual Care (UC) treatment groups. The investigators hypothesize that 1) at the end of the intervention and at a 3-month follow-up, rates of adherence to guidelines for treating TUD will be greater among clinic personnel that receive the ATTOC intervention vs. clinic personnel in usual care; 2) at the end of the intervention and at a 3-month follow-up, rates of client smoking cessation will be significantly greater in clinics that receive the ATTOC intervention than among clients treated with usual care; and 3) using non-inferiority testing, at the end of the intervention and at a 3-month follow-up, there will be no significant degradation in mental health functioning or QOL among clients who receive care at clinics that received the ATTOC intervention than among clients treated with usual care.

Socioemotional processing dysfunctions (i.e., disruptions in affective, cognitive, and neural processes that encode, interpret, and respond to socially and emotionally relevant stimuli) have been implicated in tobacco smoking and relapse, however this potential target for medication development has not been systematically examined. Evidence from animal and human laboratories indicate that administration of intranasal oxytocin enhances socioemotional processing and may be efficacious for the treatment of drug addiction, including nicotine dependence. In order to evaluate the potential efficacy of intranasal oxytocin for smoking cessation, this laboratory-based proposal will examine whether intranasal oxytocin attenuates smoking lapse, nicotine withdrawal, and socioemotional processing disruptions in regular smokers following overnight abstinence.

This study will help determine if menthol administered by inhalation via electronic cigarettes (e-cigarette) changes the reinforcing effects of pure nicotine administered intravenously in cigarette smokers who smoke mentholated or non-mentholated cigarettes.

The main goal of this project is to compare two different approaches to reducing levels of nicotine in cigarettes: an immediate reduction in nicotine content in cigarettes to non-addictive levels or a gradual reduction in nicotine content in cigarettes to non-addictive levels. These two approaches will then be contrasted to a group that continues to smoke cigarettes with nicotine content similar to conventional cigarettes.

The study is designed to test the hypotheses that financial incentives can increase both participation in smoking cessation treatment and resulting cessation rates, when they are offered to BadgerCare Plus (Medicaid) smokers as part of their health care.

People with schizophrenia have two- to three-times the mortality risk of the general population. This is primarily due to their unusually high rates of cigarette smoking, as well as other cardiovascular risk factors such as physical inactivity, obesity, high blood cholesterol and diabetes. Effective smoking treatments are needed to reduce morbidity and mortality in this population. Over a dozen experimental studies indicate that walking and other forms of exercise acutely reduce cigarette craving, nicotine withdrawal symptoms and smoking behavior in non-psychiatric smokers. However, the effects of acute exercise on smoking measures have not been studied in smokers with schizophrenia. This study will use a within-subjects, repeated-measures design, in which participants will undergo 4 laboratory sessions (order counterbalanced across participants): (1) smoking cues followed by exercise, (2) smoking cues followed by passive activity, (3) neutral cues followed by exercise, (4) neutral cues followed by passive activity. Outcome measures include cigarette craving, nicotine withdrawal symptoms, mood and smoking behavior. If the results of this study indicate that walking acutely reduces craving and smoking in smokers with schizophrenia, the next step in this research would be to test the effectiveness of a smoking cessation intervention that incorporates exercise bouts as a behavioral strategy for improving smoking cessation rates in this population.

The purpose of this study is to assess the bioequivalence between two new oral nicotine replacement therapy products and Nicorette® microtab.

Study to determine the safety and effectiveness of silver salt in Ariva® Silver Wintergreen Lozenge on discouraging smoking, by its imparting an unfavorable taste to the smoker when tobacco is smoked.

Airway dendritic cells control pulmonary immune responses to inhaled particles. It is the aim of the present study to investigate the acute effects of smoking on the number and surface molecule expression of human airway dendritic cells.
