Filter by:This is a single-center, randomized, controlled, open-label, cross-over study with healthy adult smokers. The study will investigate the nicotine pharmacokinetic (PK) profiles of two e-liquid variants used with the P4M3 Gen 2.0 e-cigarette, compared to smoking combustible cigarettes. In addition, pharmacodynamic (PD) effects (subjective effects and related behavioral assessments), will be evaluated to provide further insights on product evaluation, craving, liking, puffing topography. The study will be conducted with three periods and six sequences in a cross-over design. This study is exploratory and there is no pre-specified hypothesis to be tested.
The study will test the hypothesis that varenicline, when added to group behavioral and texting support for vaping cessation, will improve vaping abstinence rates in adolescents dependent on vaped nicotine over placebo plus group behavioral and texting support for vaping cessation. Approximately 225 adolescents will be randomly assigned to one of three arms (1) varenicline up to 1 mg bid for 12 weeks plus behavioral and texting support for vaping cessation (2) identical appearing placebo plus behavioral and texting support and (3) monitoring only. The primary comparison will be the double-blind, placebo-controlled comparison of vaping cessation rates in those assigned to varenicline vs placebo.
Tobacco use is the single greatest preventable cause of morbidity and mortality in Canada, accounting for 48,000 deaths and $16.2 billion annually in attributable health-related costs. Parents who smoke are often medically underserved and visit their child's doctor more than their own; 25% of all adult smokers have children seen in child healthcare. When parents quit smoking, their life expectancy is increased by more than 10 years, tobacco-related poor pregnancy outcomes are eliminated, children's risk of becoming smokers decreases 4-fold, families have more money for necessities, and children are less likely to suffer from diseases caused by tobacco smoke exposure. Despite free tobacco cessation services in every province and widespread insurance coverage of NRT, parental tobacco screening and cessation support rarely happens in pediatric care, thus there is potential for major health benefits from a routinely delivered tobacco control program to parents in this setting. The investigators will conduct a 12-month single centre, pragmatic, single-blind pilot RCT of CEASE vs. usual care of 70 parents who use cigarettes and/or vaping products whose children are seen in pediatric clinics at the CHU Sainte-Justine. A similar trial, CEASE-A will be conducted with 70 adolescents ages 14-17. Objectives: 1. Perform a pilot RCT of the Clinical Effort Against Secondhand Smoke (CEASE) intervention in Canada. CEASE is an evidence-based parental smoking cessation intervention to ensure that every parent who uses cigarettes and/or nicotine vaping products and visits their child's pediatrician receives nicotine dependence treatment 2. Conduct an ancillary pilot RCT of CEASE-A to deliver evidence-based support for adolescents who use tobacco and/or nicotine vaping products Outcomes include pilot process outcomes and preliminary effectiveness outcomes to assess feasibility and inform the preparation of a future large-scale RCT. This pilot RCT will provide the data necessary to plan a fully powered RCT assessing the effectiveness of CEASE and CEASE-A for smoking and vaping cessation.
The overall goal of this study is to increase knowledge of vaping and its associated risks. This study will find the patterns of vaping, and how it all started among adolescents. Investigators want to know if students are aware of the serious and long term effects of vaping. This program titled, "To Vape or Not to Vape", will provide education to adolescents and young adults about the potential risk of vaping in an effort to assist with lowering the usage rates within the population. Content will include information about current statistics, potential short-term and long-term side-effects, and healthy alternatives for dealing with stress and peer-pressure. Investigators anticipate that this program will increase this population's knowledge about the risks of vaping products, and deter them from future use of the products. Effectiveness of this program will be measured by pre and post-tests. Investigators believe this program will make at least 50 percent of the participants more aware of the dangers and consequences of vaping, potentially lowering the rates of those participating in this habit while also preventing others from starting.
The dramatic increase in the use of e-cigarettes among U.S. adolescents has been called a national epidemic, with more adolescents now using e-cigarettes than traditional cigarettes. The high amounts of nicotine in e-cigarettes harm adolescents and put them at greater risk of becoming traditional cigarette smokers. The investigators propose to develop Vaper-to-Vaper (V2V), a suite of mobile peer driven tools including peer texting and coaching based on lessons learned in the investigators' prior tobacco intervention work, to engage and help adolescents use strategies to manage cravings and successfully quit.
Electronic nicotine delivery systems (ENDS/e-cigarettes/vaping) are increasingly popular among teenagers around the world. The safety and potential adverse effects of ENDS in this population are largely unknown. While the aerosol, that users inhale, appears safe under laboratory conditions, there are still open questions, which have not yet been assessed. These cover (a) differences in exposure to chemicals (such as metabolites of Volatile Organic Compounds (VOCs) and metabolites of Polycyclic Aromatic Hydrocarbons (PAHs)) between healthy teenagers using ENDS and healthy teenagers not vaping, (b) effects of exposure to such chemicals on the body (measured by lung health indicators: airway symptoms such as coughing; lung function and lung structure tests; immune response of airway cells exposed to vapor; markers of oxidative stress), and (c) the role of nicotine metabolism. It is unknown which lung health indicator/s is/are most relevant to assess the effect of ENDS on lung health in teenagers. The primary hypothesis of this study is that there will be differences in exposure to chemicals, resulting in more or more severe airway symptoms in vaping teenagers compared to their non-vaping peers. While there might not yet exist any differences regarding lung function or structure, we expect already visible effects of vaping on the local immune response of primary cells isolated from airways in vaping teenagers as compared to non-vaping peers. In this study, participants of the Bern Basel Infant Lung Development (BILD) cohort, a birth cohort of healthy term-born infants and their follow-up, will serve as healthy, non-vaping controls.1 Vaping teenagers will be recruited independently from the BILD study through advertisements and visits to Bernese schools. Both populations combined represent the study population of the e-BILD study. All e-BILD study participants will undergo the same investigations. While these are currently planned for once in a time (so-called cross-sectional design) to compare results from non-vaping BILD study participants to otherwise healthy but vaping teenagers, repeated measures might follow, depending on the findings of the first phase.
The people of the U.S. Affiliated Pacific Islands (USAPI) face higher cancer incidence, especially lung/bronchia and head-and-neck cancer, and poorer cancer outcomes, compared with the U.S. nationally. This may partly be driven by the high rates of cigarette smoking and betel (areca) nut use in the USAPI. Previous data suggest that that adolescents on Guam, as young as middle school students report markedly higher e-cigarette and tobacco product use prevalence in the USAPI compared with the USAPI nationally. Guam youths are also at risk for the use of betel nuts. Yet, currently there are no tobacco product/areca nut use prevention programs that have been developed for and tested specifically USAPI adolescents. The proposed study will develop a school-based substance use prevention curriculum for e-cigarette, tobacco product, and areca nut use prevention among Guam youths. The curriculum will use lessons incorporating innovative videos and culturally grounded activities. The study's specific aims are: 1. To develop a school-based curriculum for e-cigarette, tobacco product (i.e., cigarette, smokeless tobacco), and betel nut use prevention among middle school students in Guam. 2. Test the efficacy of the school-based curriculum in a randomized controlled trial.
This research study, conducted by Truth Initiative, will help us learn how text messaging can help adolescents between 13 and 17 years of age quit vaping.
To examine reward processing and cognitive control both with and without the influence of vaporized nicotine in young adults with no history of cigarette use using EEG and fMRI. The goal is to determine whether acute nicotine administration using a Juul device would impact functional correlates of reward and inhibitory control in people who commonly use juul devices.
The aim of this study is to determine if graphic messages prevent future vaping use among African American and Latino adolescents. The images have been developed in a user-design model and include four main themes: health reward, financial reward, self-efficacy, and social norms. We will assess pre- and post-exposure reactions on likelihood of future vaping among African American and Latino adolescents.
