Filter by:This will be a single-center, single-blind, four-cohort, 22-day ambulatory study during which up to 24 healthy adult subjects [6 smokers (SMK), 6 moist snuff consumers (MSC), 6 vapers (VAP), and 6 non-tobacco consumers (NTC)] will complete 3 measurements of lung permeability. Nasal epithelial cells, sputum, and blood samples will also be collected for current and future biomarker research.
Individuals with substance use disorders (SUD) have to cope with drug-related cues and contexts, which can affect instrumental drug seeking as shown with Pavlovian to instrumental transfer (PIT) paradigms in animals and humans. The investigators aimed to investigate the impact of acute and chronic stress on Pavlovian-to-instrumental transfer (PIT), how PIT it is associated with cognitive control abilities and whether such effects predict losing vs. regaining control in subjects with AUD. Moreover, the investigators aimed to develop a novel full transfer task that assesses both, general and specific PIT to investigate whether specific PIT differs between alcohol use disorder (AUD) and control subjects.
The purpose of this Actual Use Study (AUS) is to investigate how United States (US) adult tobacco consumers 21 to 60 years of age, inclusive, who are regular smokers (≥5 cigarettes/day on at least 20 of the past 30 days) will use the Cartridge-based ENDS investigational products (Study IP) over a 6-week Actual Use Period (AUP) in their real-life/naturalistic environments. Subjects will be able to choose freely among the Study IP available in one of the three study arms to which they are randomly assigned. The three study arms are organized by Study IP flavor categories: tobacco, menthol, and non-tobacco-non-menthol (NTNM). Subjects will self-report their ad libitum use of the Study IP as well as use of Combustible Cigarettes (CC) and any other tobacco- and nicotine-containing product (TNP) on a daily basis using an electronic diary (eDiary).
Background: Many people who smoke use vaping products to help them quit. Levels of toxicants in urine samples are substantially lower in those who exclusively vape compared to those who smoke, suggesting that vaping poses only a fraction of the harms as smoking. However, vaping is still not risk free, with some studies finding higher levels of some toxicants among vapers compared to those who do not smoke or vape. People with mental health conditions have different smoking patterns compared with the wider general population. It is not known if people with mental health conditions have different vaping pattens, therefore researchers do not know if they are exposed to different levels of vaping related toxicants. Also, smoking exposes people to high levels of polycyclic aromatic hydrocarbons (PAHs), which can reduce the effectiveness of some psychotropic medication and management of symptoms. Vaping exposes people to lower levels of PAHs than smoking, however it is unknown if the levels of PAHs from vaping affect the metabolization of psychotropic medicines. The goal of this observational study is to learn about levels of tobacco toxicants among people with mental health conditions who vape, smoke, dual use or do neither. The main question[s] it aims to answer are: What are the levels of biomarkers of toxicant exposure among those who use community mental health services who exclusively vape, exclusively smoke, dual use or do neither, and how do they change over time? What is the difference in clozapine excretion levels and metabolism among those who use community mental health services who exclusively vape, exclusively smoke or dual use or do neither? Participants will self report smoking and vaping characteristics and provide blood and urine samples at baseline and six months later. Urine will be analysed for tobacco toxicants. Blood will be analysed for levels of clozapine and other prescribed anti psychotic medication. Researchers will compare levels of toxicants between people who vape, smoke, dual use, or do neither to see if these is a difference.
The goal of this evaluation study is to evaluate the KickAsh! intervention, an intervention aiming to prevent smoking initiation in adolescents living in vulnerable socioeconomic situations. This intervention will be implemented in youth social work organisation that offer sport and/or recreational activities for these adolescents. Youth workers will act as implementers of the intervention. The main aim of this study is to evaluate the effect of the intervention, whether it does or does not produce change in the smoking initiation behaviour of adolescents (= effect evaluation). Secondly, the study aims to evaluate the implementation process to generate more understanding concerning why the intervention does or does not produces change. Therefore, it will be investigated how the intervention was implemented, what exactly was implemented, in which context the intervention was implemented... (= process evaluation) For the effect evaluation adolescents will be asked to fill in a questionaire at three time points. For the process evaluations interviews and focus groups will be organised with the adolescents and youth workers respectively. Two groups will participate to this study: one group existing of organisations where the intervention will be implemented (=intervention group), and one group where the intervention will not be implemented (= control group).
The purpose of this study is to describe the nicotine pharmacokinetic (PK) profile during and after single use of THS (Induction heating technology, with either a regular or menthol stick) compared to singular CIG smoking in healthy adult subjects. In addition, pharmacodynamic effects (subjective effects) will be evaluated to provide further insights on product acceptance and likelihood to use the THS again. Safety will be assessed throughout the study.
The goal of this research study is to test an intervention to help quit tobacco use in participants with Human Immunodeficiency Virus (HIV). The study interventions used in this research study are: - Positively Smoke Free - Mobile (PSF-M) (mobile behavioral program) - Varenicline (or Chantix, apovarenicline, Champix or Nocrav)
The goal of this clinical trial is to evaluate the effectiveness and implementation of a pharmacist-delivered MTM (medication therapy management) approach, called QuitAid, to quitting cigarette smoking in rural Appalachia. The main questions it aims to answer are: - Is QuitAid, alone or combined with other quitting tobacco treatments, effective? - What makes QuitAid easy or hard to carry out? Is it cost effective? Is it easy to maintain? Treatment: All participants will be given at least 4 weeks of the nicotine patch. Some participants will be randomized (like the flip of a coin) to receive additional treatments (listed below). These groups will be compared to each other to see which combination works best to help them quit smoking. - Smokefree TXT - a texting program that helps people quit smoking - Tobacco quitline - 4 phone sessions to help people quit smoking - 8 weeks of NRT (nicotine replacement therapy in the form of nicotine patches or nicotine patches and lozenge) medication instead of 4 weeks - QuitAid - An MTM program given by the patient's pharmacist. This is a quitting smoking coaching program - Nicotine patch AND nicotine lozenge instead of just nicotine patches
Few countries have legislation to reduce the number and types of tobacco retail outlets. The Netherlands plans to ban tobacco sales in supermarkets in 2024. The overall aim of this proposed research is to evaluate the implementation of new legislation to reduce the number and types of tobacco outlets in the Netherlands, up until and including the ban on sales of tobacco in supermarkets. In a comprehensive policy evaluation, the investigators plan to examine (1) the impact of the policy on the number and types of tobacco outlets, (2) the impact on attitudes and behaviors of smoking adults and non-smoking youth, and (3) the influence of the tobacco industry on the policy process and the retail environment. In addition, the investigators plan to focus on differential effects in disadvantaged neighborhoods, where both smoking rates and tobacco outlet density are typically highest. The investigators bring together a unique combination of economic, psychological, and journalistic research methods. The investigators examine the impact of the new legislation on the amount and type of tobacco outlets and on the number of smokers by using routinely collected monitoring data. The investigators examine the impact of the legislation on smoking susceptibility of non-smoking youth and on impulse tobacco purchases by smoking adults with yearly quantitative surveys (two surveys before the policy implementation and two after) and with qualitative interviews and discussion sessions. The investigators examine whether these impacts differ for disadvantaged versus non-disadvantaged neighborhoods. The investigators examine what strategies the tobacco industry uses to influence the new legislation, policy processes, and the tobacco retail environment by performing a journalistic investigation, using for example documents obtained by Freedom of Information Act requests, (possibly) leaked documents from insider meetings, and interviews with insiders. Our research will provide a comprehensive evaluation of the effects of the implementation of the proposed legislative measures. Based on our results, the investigators will formulate recommendations for the Dutch Cancer Society, the Dutch government, and for other countries who consider reducing the number of tobacco outlets; highlight potential areas for further development and improvement within the legislative framework and provide recommendations on how to counter the lobby from the tobacco industry.
The investigators will conduct a message-exposure experiment with nationally representative samples of smokers, dual-users (cigarettes and e-cigarettes), and young adult non-smokers (aged 18-29). Experimental messages will address the reduction of nicotine in cigarettes. Participants will also complete a follow-up survey after 2 weeks, measuring their recall of the messages and behaviors since message exposure.
