Active clinical trials for "Tobacco Use Disorder"

In this pilot study, menthol cigarette smokers will be randomized to one of three experimental marketplaces: 1) a condition simulating a ban on menthol cigarettes but not menthol e-cigarettes (condition A); 2) a condition simulating a ban on both menthol cigarettes and menthol e-cigarettes (Condition B); and 3) a condition in which menthol is not banned for either product (Condition C - the control condition). All conditions would have medicinal nicotine available if subjects decide to quit tobacco products entirely. At visits occurring every two weeks over a 6 week period, subjects will receive "credits" that they could exchange for any product available in their randomized marketplace condition. Outcomes include the amount of each tobacco product used.

This study is about whether or not little cigars and cigarillos cause or maintain addiction, and if flavors, such as fruit, make them more addictive. The purpose of this study is to understand the addiction potential of little cigars and cigarillos compared to cigarettes in young adults who smoke both products. This study will also look at the differences between men and women. In the rest of this form, little cigars or cigarillos will be referred to as LCCs.

The primary purpose of the current study is to test the effect of providing users of automated web-based smoking cessation interventions with the option of negotiating and re-negotiating the quit date.

The goal of this project is to experimentally evaluate how expectations about reduced-nicotine cigarettes as well as actual nicotine content interact to determine behavioral and subjective response for these novel products.

Randomized controlled trial of electronic cigarettes with nicotine, without nicotine, and sham control, on sympathetic nerve activity and markers of oxidative stress.

In the current study, the investigators propose to test: (1) whether brain activation and connectivity in a resting state, assessed by ASL perfusion MRI, BOLD fMRI, and diffusion tensor imaging (DTI) predicts smoking relapse, and (2) whether brain activation, assessed by BOLD fMRI during performance of neurobehavioral probes for executive cognitive function, stress and cue reactivity, predicts smoking relapse.

This is a molecular imaging research study designed to examine how much nicotine gets into the brain before and after vaccination with NicVAX, a nicotine vaccine developed by Nabi Biopharmaceuticals. NicVAX (Nicotine Conjugate Vaccine) is an investigational vaccine designed as an aid to smoking cessation and long-term abstinence, as well as an aid to prevent relapses of a treated smoker. In this project we want to understand the degree to which NicVAX administration changes how much nicotine enters the brain in smokers.

RATIONALE: Diagnostic procedures, such as an urgent chest x-ray, may help in planning cancer treatment. It is not yet known whether standard medical care is more effective than an urgent x-ray in diagnosing lung cancer in smokers with chest symptoms who are older than 60 years. PURPOSE: This randomized clinical trial is studying standard medical care to see how well it works compared with an urgent chest x-ray in diagnosing lung cancer in smokers with chest symptoms who are older than 60 years.

The purpose of the study is to obtain two year follow up data for subjects that received six vaccinations of NicVAX in prior phase III studies. No treatment will be administered. Anti-nicotine antibody levels and safety data will be collected.

This randomized clinical trial studies enhanced quitline intervention in smoking cessation for patients with non-metastatic lung cancer. Stop-smoking plans suggested by doctors may help patients with early-stage cancer quit smoking
