The purpose of this research study is to understand whether concurrent treatment for cigarettes and e-cigarettes in which an individual quits both products at the same time (QUIT-C) or sequential treatment in which an individual quits cigarettes first followed by e-cigarettes is more effective for quitting both products. The study will also compare the effect of treatment on health-related biomarkers. All participants will receive varenicline, a medication used to treat tobacco use dependence, counseling, and cessation resources (i.e., links to text-based support, self-change booklet). Varenicline helps to reduce cravings for tobacco use and decreases the pleasurable effects of cigarettes and other tobacco products.
This study will investigate the effects of promotion factors and mitigation strategies on legal and illegal tobacco purchases for different tobacco-user types.
This study assess the ways in which e-cigarette product characteristics, such as flavors and nicotine salts, impact user experience to inform potential regulations.
This study assess the ways in which e-cigarette product characteristics, such as marketing strategies, impact user experience to inform potential regulations.
This project will assess the ways in which e-cigarette product diversity impacts the user experience to inform potential regulations by identifying product characteristics that may: (1) put young adults at risk for tobacco product use; and (2) facilitate adult smokers switching to e-cigarettes. There are three primary objectives to the study: (1) Determine which dimensions of e-cigarette product diversity differentially affect product appeal in the overall population of tobacco product users as well as affect product appeal across young adult e-cigarette users and middle-age/older adult smokers; (2) Determine which dimensions of e-cigarette product diversity differentially affect product appeal in the overall population of tobacco product users as well as affect abuse liability in young adult e-cigarette users and the ability to resist smoking in adult smokers; (3) Determine the affect of product characteristics on e-cigarette nicotine delivery profile. For this substudy, adult smokers (N=200) will attend two laboratory session in which they will self-administer e-cigarette products varied according to within-subject e-cigarette factors (e.g., flavor, nicotine formulation) and smoke their own cigarettes.
This study will experimentally assess the comparability of in-lab and remote procedures with hypothetical and real ETM purchase outcomes.
In this open-label, randomized controlled trial study, participants who smoke combustible cigarettes (CC) and are diagnosed with Serious Mental Illness (SMI) will be randomized in two arms to receive harm-reduction counseling and Ecological Momentary Intervention text messaging (EMI) along with either e-cigarettes (EC) or nicotine replacement therapy (NRT) such as patch and lozenges to compare the efficacy in CC smoking reduction.
This proposed project is to assess the efficacy of CBT-based digital smoking cessation interventions in China, as well as explore its neuroimaging mechanisms.
Investigators will examine whether adding financial incentives and nicotine replacement dual therapy to current best practices for smoking cessation (i.e. referral to counseling using a telephone quit line) increases cessation rates in mothers and reduces second-hand smoke exposure in children. While perhaps more expensive upfront compared to best practices alone, the investigators hypothesize that this treatment approach will be a more cost-effective cessation intervention.
