NCT ID: NCT06264154 Not yet recruiting - Smoking Clinical Trials

The Role of Flavor in the Substitutability of E-cigarettes for Combustible Cigarettes Among Persistent Smokers

Start date: July 2024
Phase: N/A
Study type: Interventional

This between-subjects study aims to evaluate the effect of flavor on initial and sustained switching from combustible cigarettes to e-cigarettes among 210 cigarette smokers. After measuring baseline cigarette smoking rate, participants will be randomized to a six-week regimen of fruit-flavored, tobacco-flavored, or menthol-flavored e-cigarettes and be instructed to switch (versus smoking cigarettes) over a 6-week period. Flavor-associated subjective reward and the reinforcing value of flavored e-cigarettes relative to combustible cigarettes will be assessed as mechanisms.

NCT ID: NCT05958966 Completed - Cigarette Smoking Clinical Trials

Effects of e-Cigarettes on Perceptions and Behavior - Substudy 2

Start date: April 1, 2022
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT05932693 Not yet recruiting - E-Cig Use Clinical Trials

Effect of Different E-cigarette Cooling Flavors on Adults' Sensory Experience TCORS 3.0

Start date: July 1, 2024
Phase: N/A
Study type: Interventional

This pilot sensory experiment will examine cooling from comparable concentrations of WS-3 and menthol to determine appropriate concentrations to use in the main study.

NCT ID: NCT05869318 Recruiting - E-Cig Use Clinical Trials

Respiratory Effects of E-Cigarettes in Obese Youth

RESEC
Start date: April 4, 2023
Phase: N/A
Study type: Interventional

NCT ID: NCT05482581 Recruiting - E-Cig Use Clinical Trials

The Impact of Policies Regarding E-cigarette on Adolescents and Young Adults' Cognition and Behavior for E-cigarette

Start date: May 27, 2022
Phase:
Study type: Observational

Based on the Knowledge,Attitude,Belief and Practice model(KABP model), this study intends to use a mixed method to explore the influencing mechanism of youth and adolescents' cognition and behavior for e-cigarette before and after the promulgation of the new regulations on e-cigarette . Information from network epidemiology (including network links, text, images, audio, video, etc.) was captured to expand the data abundance, and the retrieval behavior of e-cigarettes and the trajectory changes of e-cigarette-related events were explored. Finally, summarize the data, integrate and explain the influencing mechanism of youth and adolescents' attention and cognition on e-cigarette, and provide ideas for subsequent e-cigarette control, as well as theoretical and practical basis for relevant departments to formulate corresponding policies.

NCT ID: NCT05477888 Completed - E-Cig Use Clinical Trials

Psychometric Properties of the Chinese Version of Penn State [Electronic] Cigarette Dependence Index

Start date: May 27, 2022
Phase:
Study type: Observational

The purpose of this study is to realize the first evaluation of the psychometric characteristics of the Chinese version of the the Penn State University Electronic Cigarette Dependence Index Scale.

Impact of New Standards for Tobacco Products Among Dual E-Cigarette/Combusted Cigarette Users - Project 2

Start date: October 12, 2022
Phase: N/A
Study type: Interventional

The purpose of the study is to evaluate how limiting the nicotine content in regular cigarettes affects choices for regular cigarette and e-cigarette products. Eligible participants will be of legal age to purchase tobacco products and regularly use both e-cigarettes and regular cigarettes.

Understanding the Impact of Cartridge-Based Electronic Cigarettes and Generated Aerosols on Cardiopulmonary Health

Start date: January 10, 2022
Phase: Early Phase 1
Study type: Interventional

Over the last decade, e-cigarettes have become increasingly popular, due to their promotion as a healthy alternative to traditional tobacco cigarettes.
