Filter by:This is a multi-center, randomized, controlled, partially blinded study to assess the pharmacokinetics and comparative bioavailability of nicotine from two variants of NP2 (4 and 6 mg) in comparison with Loz-4mg and Gum-4mg in adult cigarette smokers. The subjects will be blinded to the randomized sequence and will be blinded to the variants of NP2 they will receive. The study will be conducted with 4 periods and 4 sequences in a Williams design (crossover).
This is an observational study of participants in two general population health surveys (FinSote 2018 and 2020) who are followed up for their COVID-19 vaccinations or end of follow-up. The primary objective is to examine the association between tobacco use and COVID-19 vaccine uptake and between-dose spacing.
Tobacco use is increasing among youth in the U.S. However evidence for the long-term effectiveness of tobacco cessation programs for youth is limited. The current study seeks to adapt and evaluate a universal group-based youth brief tobacco intervention for 9th grade students. This study will use a sequential, multi-method research design beginning with qualitative roundtable discussions with 9th grade students to adapt an existing young adult brief tobacco intervention for youth. Roundtable discussions with students will identify salient intervention themes and strategies for targeting the intervention and developing the text messages. The second phase of the study evaluates the brief intervention, UP2UTobacco, through a cluster randomized controlled trial that compares UP2UTobacco to a no treatment control. It is hypothesized that the UP2UTobacco will produce greater abstinence at the 6-month follow-up compared to the no treatment control. Roughly 90% of daily smokers started before the age of 18, and 2,000 youth smoke a cigarette for the first time each day in the U.S. Additionally, e-cigarette use is on the rise among youth, and is linked to cigarette initiation among tobacco naïve youth. In order to curb the rise of tobacco use among youth, interventions that are easily implemented and easily disseminated need to be developed for youth addressing currently available products and contemporary patterns of use. If the interventions in the current study are proven efficacious, they can easily be disseminated to other schools to continue reducing youth tobacco use.
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.
This research project will explore the feasibility and acceptability of a web-based media literacy tobacco prevention program. The project will be conducted with 9th or 10th graders in two high schools in Pittsburgh, Pennsylvania.
This within-subjects study aims to evaluate the effects of IQOS use on combustible cigarette smoking behaviors among 100 cigarette smokers who completed the study. After measuring baseline cigarette smoking rate, participants will receive an IQOS device and be instructed to use it (versus cigarettes) over a 14-day period. The investigators will also examine which objective and subjective effects of IQOS use predict a complete and incomplete switch from cigarettes to IQOS.
The goals of this project are to determine the effects of varying degrees of cigarette filter ventilation on biomarkers of toxicant exposure and smoking behavior and on subjective responses to the cigarette. The primary aim of this study is to examine the effects of unventilated vs ventilated filter cigarettes on urinary biomarkers of toxicant exposure and smoking behavior (e.g., cigarettes per day, intensity of smoking). The secondary objectives are 1) to examine the effects of cigarette filter ventilation on subjective measures such as cigarette dependence and responses to study cigarettes.
The purpose of this study is to evaluate the effect of various tobacco products (including but not limited to combustible cigarettes, medicinal nicotine, electronic cigarettes, and smokeless tobacco) on cutaneous wound healing. There will also be a non- smoking control group. This study will be designed as a pilot study. The majority of individuals will be recruited from ongoing studies at the University of Minnesota - Tobacco Research Programs.
Interventions to disrupt memory reconsolidation have held promise for the treatment of stress- and anxiety-related disorders. In the present study, the investigators will examine whether an intervention based on these principles, called memory updating, could be adapted for reward-seeking behaviors. To test this, non-treatment seeking tobacco smokers will be exposed to smoking cues and/or stress, two stimuli known to trigger smoking. It is predicted that exposure to a stress task will enhance the cues' motivational salience and yield greater susceptibility to the memory updating procedure. As an add-on, the investigators will examine COVID-associated changes in substance use and whether participants in the memory updating groups might be more resilient to these effects. It is predicted that the changes in substance use will depend on whether the substances are used primarily in social settings.
According to the 2015 Ontario Student Drug Use and Health Survey (OSDUHS), there has been a significant increase in the number of secondary school youth who use poly-substances. Not all youth have the same risk for problematic substance use. Health literature documents a high level of comorbidity between mental health and substance use, which is exacerbated in homeless youth populations. Therefore, the proposed study will focus on understanding poly-substance use among at-risk homeless school youth. As seen in substance use research and the PROMPT (2016) study (Participatory Research in Ottawa: Management and Point-of-Care for Tobacco Dependence, PI: Dr. Smita Pakhale), reduction and quitting of one substance (tobacco smoking) can lead to the reduction and quitting of other poly-substance use. A Community-Based Participatory Action Research (CBPAR) approach can help at-risk youth feel safe and comfortable enough to provide personal information about their poly-substance use and engagement with treatment or harm reduction programs. This project will be a first step in increasing health equity among at-risk homeless youth in Downtown Ottawa. The investigators aim to follow a group of at-risk youth to while providing an appropriately modified PROMPT intervention, including peers support and a licensed mental health and substance use nurse.
