Filter by:Randomized controlled trial of acute use of electronic cigarette or tobacco cigarette on parameters of ventricular repolarization and inflammation/oxidative stress.
The primary aims of this pilot study were to (1) initially validate the applicability of a human laboratory model of relapse initially developed for smokers to e-cigarette users; (2) to use this human laboratory model of lapse behavior to examine the effects of acute psychological stress on vaping-lapse behavior among adults who are experienced, e-cigarette users.
The purpose of this study is to examine the effect of exposure to vape education messages on beliefs, perceptions, norms, and behaviors related to electronic vapor product use.
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, young adult vapers (N=100) and adult smokers (N=100) will attend one laboratory session in which they will self-administer e-cigarette products varied according to within-subject e-cigarette factors (e.g., flavor, nicotine formulation).
This study aims to characterize the pharmacodynamic response to vaped THC in young adult, occasional cannabis users with respect to outcomes such as stimulation and sedative effects, mood, anxiety, and craving, as well as cognitive and objective outcomes such as heart rate and cortisol changes with THC vs placebo.
Researchers are gathering information on the feasibility of treating e-cigarette users with 12-weeks of varenicline (Chantix®) in assisting with stopping the use of e-cigarettes.
To assess smoking, vaping, and alcohol consumption behaviors via online surveys in the population. Further, the objective is to administer additional surveys to assess which methods (e.g., pen-and-paper records, a smartphone app) for monitoring smoking, vaping, alcohol intake, and food intake are preferred by the study population.
The use of the Invite Only VR, with the aim to prevent the initiation of e-cigarette use in teens by increasing their knowledge, decreasing their intentions to use e-cigarettes, influencing their harm perceptions and attitudes associated with e-cigarettes, and increasing self-efficacy associated with refusing peers involving e-cigarettes.
This is an observational, crossover design that will examine the pharmacokinetics and pharmacodynamics of impact of smoking tobacco cigarettes or vaping the JUUL electronic cigarette.
This is a single-center, open-label, concentration-ranging study to evaluate the nicotine PK profile and PD effects in healthy adult experienced users of closed tank/cartridge e-cigarettes using four different variants of P4M3 (nicotine concentration of 1.7%, 1.7% with 1.1% lactic acid [LA], 3% with 1.1% LA, and 4% with 2% LA) or their own e-cigarettes.
