Active clinical trials for "Tobacco Use Disorder"

The purpose of this study is to evaluate the relationship between craving to smoke and areas activated in brain. The researchers are using functional magnetic resonance imaging (MRI) that measures brain blood flow, or perfusion, to study this brain activation.

This clinical trial studies deuterated phenanthrene tetraol in smokers who are at high risk for lung cancer. Studying samples of urine in the laboratory from smokers who are at high risk for lung cancer may help doctors learn more about biomarkers related to cancer.

Adults with substance use disorder (SUD) tend to have started smoking at a younger age and are more likely to be heavy smokers. Due to the many conflicting priorities in this population, smoking cessation is often relegated and ignored by both patients and their healthcare providers. As of 2008, only 2 out of 5 addiction treatment providers in the US offered behavioral treatment for smoking cessation, and less than 1 in 5 offered pharmacotherapy. However, many researchers have found that smoking cessation has positive effects on abstinence from other drugs, as smoking appears to increase craving for and the likelihood of using drugs. Contingency Management is a highly-effective, evidence based methodology demonstrated to be effective at reducing the use of all types of substances in over 100 randomized controlled trials and 7 meta-analyses. BrightView, an outpatient substance abuse treatment center with several locations across the state of Ohio, has partnered with DynamiCare Health to implement DynamiCare's innovative digital Contingency Management (CM) platform among BrightView's outpatient population of primarily low-income substance use disorder patients with comorbid nicotine dependence/tobacco use disorder. DynamiCare's platform automates Contingency Management to support smoking cessation interventions via smartphone app. This app rewards participants for negative substance tests and appointment attendance (using GPS tracking) to incentivize abstinence and promote engagement in treatment. The goal of this study is to reduce tobacco disparities for low-income adult participants using DynamiCare's digital intervention, and to build a rapidly scalable, sustainable process that makes the field of smoking cessation more effective, accountable, and accessible.

RATIONALE: Collecting and storing samples of sputum and tissue to study in the laboratory may help doctors identify biomarkers related to cancer. PURPOSE: This research study is looking samples of sputum and tissue from lung cancer patients, participants at high risk for developing lung cancer, and from healthy volunteers (both smokers and non-smokers).

The purpose of the experiment is to examine the effect of smoking on how individuals recognize and interpret sensory information.

RATIONALE: A counseling program that motivates patients to stop smoking and drinking may reduce the risk of oral cancer. It is not yet known whether motivational stop smoking counseling or motivational stop-smoking and stop drinking counseling is more effective in helping patients stop smoking and drinking. PURPOSE: This randomized clinical trial is studying how well treatment to stop smoking and drinking works in preventing oral cancer in smokers in Puerto Rico.

The objective of the present study is to identify brain networks in patients that contribute to successfully learning self-regulation with real-time fMRI.

The survey participants are divided into a smoking and non-smoking group. The smoker group is further divided according to the quantity and quality of nicotine ("normal" smoking, vaping). After reaching a steady state, the cutaneous blood flow at rest in the extremities of all participants is determined by Laser Doppler Imaging as a reference value. Laser Doppler Imaging produces images of the blood flow using perfusion units (PU). Subsequently, the perfusion is measured again after smoking/vaping. The difference in skin perfusion of the extremities is calculated (δ-Perfusion). All measurements are performed under controlled vital parameters (body temperature, systolic and diastolic blood pressure, heart rate) and controlled room temperature as well as 15-minute acclimatization of the patients.

The purpose of this study is to determine whether combining noninvasive brain stimulation with cognitive training can reduce craving in adults with tobacco use disorder.
