Active clinical trials for "Tobacco Use Disorder"

The purpose of this study is to compare the effects of bupropion + placebo to bupropion + naltrexone as treatments to help smokers quit.

Electrical stimulation provides direct modulatory effects on subcortical regions. Indeed, neuroimaging studies show changes in neural activity in specific brain regions such as the amygdala, insula, precentral gyrus, hippocampus and thalamus. The neuroanatomical connections established with the trigeminal nerve have been associated with the mechanism called "bottom-up" neuromodulation. According to this hypothesis, the spread of electrical stimulation follows a path from the peripheral nerves towards the brain stem was then advertise for cortical and subcortical regions. Connections to structures involved in the reward system as the amygdala and hippocampus could theoretically modulate dysfunctional brain activity in these regions, which may induce favorable clinical effects.

This is a 2-arm, randomized controlled, population based trial to test the impact of multiple exposures to brief nicotine corrective messages among adult tobacco cigarette smokers and non-smokers followed in waves over 12 weeks. The primary outcome, assessed at wave 1 (baseline), wave 2 (weeks 5-6), and wave 4 (weeks 11-13) is nicotine beliefs. Secondary outcomes assessed at the same time points include intention to use nicotine/tobacco products and nicotine/tobacco use.

The purpose of this research is to develop and test a new type of smoking cessation counseling for individuals with bipolar disorder.

The purpose of this study is to determine how people react to different combinations of alcohol and nicotine.

The primary objective of this study is to determine whether the application of transdermal nicotine patches in critically ill patients after major surgery with nicotine abstinence condition is associated with a lower incidence of delirium.

This study is directed at decreasing home environmental tobacco smoking (ETS) exposure with a novel approach of adoption of home smoking restrictions. This will be done by providing the cohabitating smoker and non-smoker with biomarker feedback documenting exposure to ETS. The intent is to identify an intervention strategy(ies) to reduce ETS exposure.

This open-label study will evaluate EMB-001, comprised of metyrapone, a cortisol synthesis inhibitor marketed as a diagnostic drug for testing hypothalamic-pituitary-adrenal (HPA) axis function, combined with oxazepam, an anxiolytic and sedative/hypnotic benzodiazepine, to help smokers abstain from smoking during a 12-week trial period.

This phase I trial studies how well Flexiquit+ helps young adult smokers who identify as a sexual and/or gender minority to quit or cut down on smoking. Flexiquit+ is an avatar-led, web-based intervention that can help smokers quit or cut back on how much they smoke cigarettes and/or vape, reducing their chances of developing tobacco-related health conditions.

The purpose of this study is to determine whether DAT availability, assessed by WIN binding, in the striatum is altered in cocaine or methamphetamine dependence. To determine whether DA synthesis capacity, assessed by FDOPA uptake, in the striatum is altered in Coc or Meth dependence. To determine whether the PET tracers, WIN or FDOPA, will differentiate Meth induced alterations from those induced by Coc use. To determine whether the PET characterization of striatal alterations observed at 3-5 days since last drug use persists at least 3 months after last drug use.
