Filter by:The Cessation of Smoking Trial in the Emergency Department (CoSTED) is an National Institute for Health Research (NIHR) Health Technology Assessment (HTA) funded randomised controlled trial (RCT). The research question is "in people attending the Emergency Department who smoke, does a brief intervention (including the provision of an electronic cigarette (e-cigarette) and referral to stop smoking services) increase smoking cessation in comparison with usual care and is it cost effective?" The trial includes an internal pilot, health economic evaluation and process evaluation. The primary outcome is smoking cessation, self-reported as continuous smoking abstinence, biochemically validated by carbon monoxide monitoring with cut off of ≥8ppm. The sample size is 972 (486 in intervention and control) across 6 sites.
The purpose of this randomized controlled trial is to determine whether exposure to vaping prevention advertisements (ads) reduce susceptibility to vaping among adolescents. Previous studies have been informative, but they have tended to be one-time experimental studies that do not replicate the repeated exposures to ads that people have in the real world. This study addresses this issue by repeatedly exposing participants to vaping prevention ads over time. Participants will be adolescents aged 13-17 who currently vape or who are susceptible to vaping. Participants will be randomly assigned to ad stimuli. They will be assigned to one of two The Real Cost trial arms-health harms or addiction-or to a control trial arm (probability of assignment is 1/3 for all trial arms). Participants in the study will take 4 online surveys over a 3-week period, once per week (At week 0, 1, 2, and 3). All participants will view randomized ad stimuli based on their trial arm and answer surveys items at each session.
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).
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.
