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 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.
The goal of this observational study is to understand the burden and determinants of tobacco use and air pollution (AP) exposure among mid- to late adolescents in Greece, the Kyrgyz Republic, Pakistan, Romania, and Uganda. This context-specific knowledge will be crucial for selecting, adapting, and implementing preventive interventions in the next phase of the project. The main questions the investigators aim to answer are: - What is the perceived burden of tobacco use and AP exposure among adolescents? - What are the contextual drivers and behavioral determinants contributing to (prevention of) these risk factors? - How do the dynamics between stakeholders influence prevention efforts? In this study, data will be collected through interviews, focus group discussions, photovoice, document analysis, observations, personal exposure monitoring, and questionnaires.
The goal of this clinical trial is to learn about the acceptability, feasibility, and effectiveness of smoke-free housing policy implementation in Permanent Supportive Housing communities. The main objective of this study is to identify and refine adaptations for a smoke-free housing implementation framework that incorporates behavioral health support and meets the needs of residents living in Permanent Supportive Housing.
The purpose of this study is to 1) examine barriers and facilitators to implementation of MI and MORE for polysubstance use and evaluate strategies for optimizing training, fidelity, and clinic uptake, and 2) evaluate patient outcomes related to the effectiveness of MORE decreasing opioid, tobacco, and other drug use.
This is a crossover, randomized, double-blinded clinical pharmacology study enrolling dual cannabis-tobacco smokers to better understand the combined effects of co-administering cannabis and tobacco. The project aims to describe the pharmacokinetics and pharmacodynamics of marijuana-tobacco co-administration by delivering THC and nicotine in various combinations. This foundational study will establish a research program focused on elucidating the public health consequences of marijuana-tobacco co-use.
At the Fire Department of the City of New York (FDNY) World Trade Center Health Program, 36% of participants in the low dose computed tomography (LDCT) lung cancer screening program are current smokers, despite referral to the free FDNY Tobacco Cessation Program (Standard Care). Investigators propose testing an Enhanced Care program which includes opt-out enrollment; tobacco cessation counseling will be individually tailored to spirometry/LDCT results and treatment with varenicline starting 4 weeks prior to their target quit date. This randomized trial will compare enrollment and cessation outcomes in Standard Care vs. Enhanced Care groups of challenging-to-treat, high-risk smokers.
The objective of this trial is to evaluate the effectiveness of "nudges" to clinicians, patients, or both in increasing referral to, and engagement with, tobacco use treatment services (TUTS) for HIV patients versus usual care. This will be a four-arm pragmatic cluster randomized clinical trial. The investigators hypothesize that each of the implementation strategy arms will significantly increase TUTS referral and engagement compared to usual care and that the combination of nudges to clinicians and to patients will be the most effective.
The goal of this research is to assess whether little Cigars and cigarillos (LCC) warnings developed by the study team are more effective than the current warnings proposed by FDA for LCC products. A 3-week web-based randomized controlled trial will be conducted in the United States. Participants are adult persons who currently use LCCs.
This research study aims to develop a cognitive dissonance-based mobile app for smoking cessation (CoQuit) and test the efficacy of the app with 500 adult smokers who express a desire to quit smoking.
