Filter by:The purpose of this study was to estimate changes in biomarkers of exposure (BOE) in adult cigarette smokers using an oral tobacco-derived nicotine (OTDN) product relative to adult smokers who continue smoking exclusively.
Chronic Obstructive Pulmonary Disease (COPD) is caused primarily by smoking and smoking cessation is the first-line treatment for slowing disease progression. Despite this, nearly 50% of COPD patients continue to smoke following diagnosis. Smokers with COPD report high rates of co-occurring conditions - nicotine dependence, depression, and anxiety - which serve as barriers to quitting. The current study will pilot test a behavioral intervention designed to target the common psychological factors underlying these co-occurring conditions and foster smoking cessation among COPD patients.
The purpose of this study is to compare plasma nicotine uptake in adult snus consumers after using investigational snus products (A19010-W and B19010-F).

Smoking and dual using associated with poor periodontal health.
Due to the pandemic, this study was modified from a randomized clinical trial to test the feasibility, initial efficacy, and mechanisms of action of our PTSC-S intervention to a feasibility and acceptability test of our intervention when delivered via telehealth in a single group, within-subjects design.
This study is designed to enhance the understanding of the possible health effects of e-cigarette use by relating the acute and long-term use of e-cigarettes and conventional cigarettes ("products") to well-validated cardiovascular and pulmonary disease biomarkers. Participants will be enrolled in 3 groups: exclusive e-cigarette users, exclusive cigarette smokers, and a control group of never-users. Participants can expect up to 4 weeks of study participation.
The study aims to develop tobacco modules to be included in an innovative mobile-health (mHealth) intervention (hereon referred to as S4E) and to determine the feasibility and preliminary efficacy of the updated version of S4E in an urban youth-centered community health clinic in Southeast Michigan.
The purpose of this project is to understand how different e-cigarettes influence their likeability and use among current smokers who try using e-cigarettes. Participants will receive an e-cigarette to sample over a three week period. During this time period they will complete daily electronic diaries and weekly lab visits. The results from this information will help understand how different types of e-cigarettes are likely to influence cigarette and e-cigarette use.
