Filter by:Cigarette smoking is now the leading killer of people with HIV (PWH) in the US, and most cessation strategies tried to date have failed to increase long-term quit rates. An "all or none" approach to smoking cessation in PWH offers little benefit to the large majority of PWH who are unable or unwilling to quit. In this proposal we argue that a harm reduction approach (i.e. cut down, get screened for lung cancer, control your blood pressure and cholesterol) has the potential to yield significant benefits in terms of the private and public health of PWH in the US.
The overall aim of this research is to experimentally evaluate different, legally-viable approaches to reducing the impact of the point-of-sale (POS) retail environment on adolescent tobacco use risk. This study will be investigating regulations for four classes of tobacco products (cigarettes, e-cigarettes, smokeless tobacco, little cigars/cigarillos). Study 2 and study 3 (out of 3 studies), occurring concurrently, will examine whether changing the number and content of posters on the outside doors at POS reduced adolescents' tobacco use risk.
Most attempts to quit smoking end in relapse, or a return to regular smoking. One of the biggest threats to cessation is a lapse (i.e., any cigarette use during a quit attempt). Thus, characterizing why lapses occur is essential to understanding and preventing smoking relapse. Functional magnetic resonance imaging (fMRI) is a promising method for characterizing the psychological processes that lead to smoking lapses because it provides a way to measures patterns of brain activity thought to reflect relevant mental processes as they change over time. However, methodological issues have hindered the ability to capitalize on this potential and prevented an understanding of how brain activity and corresponding psychological processes unfold in the critical moments that immediately precede a smoking lapse. The proposed project will address this knowledge gap using a novel fMRI paradigm adapted from a well-validated behavioral lapse task. The goals of the project are to characterize changes in brain activity that lead up to a lapse and to investigate how these changes are related to concurrent affect and subsequent cigarette use.
The purpose of this study is to demonstrate the slowing of the disease progression including the improvement of Chronic Obstructive Pulmonary Disease (COPD) symptoms in smoking subjects with mild to moderate COPD and a history of chronic bronchitis symptoms (sputum and cough) who switch to the Tobacco Heating System (THS) as compared to those who continue to smoke cigarettes.
Tobacco use disorder is a chronic, relapsing health condition that necessitates a chronic care approach. However, traditional smoking cessation treatment programs allocate nearly all their resources only to those smokers who are willing to set a quit date. This is problematic because few smokers are ready to set a quit date at any given time, and a smoker's stated intention to quit can change rapidly. One novel potential treatment strategy is to foster practice quitting (PQ), defined as attempting to not smoke for a few hours or days, without pressure or expectation to permanently quit. Although a growing body of evidence supports the role of practice quitting in fostering permanent quit attempts and cessation, there is a significant knowledge gap regarding which treatment strategies should be used to engage smokers in practice quitting. The proposed study will test the role of PQ counseling vs. Motivational Interviewing (MI) counseling, and NRT sampling (four-week supply of nicotine lozenges and patches) vs. none.
This project examines the influence of flavor availability on switching to an MRTP known as IQOS, part of the Heated Tobacco Product (HTP) class, among menthol smokers using clinical lab and naturalistic evaluations of abuse liability. Results will help federal regulators predict the public health impact on menthol cigarette smokers of policies restricting access to menthol-flavored HTPs.
The goal of this study is to validate the TAPS-ESP as a screen and assessment that can be used in primary care for the screening and treatment of substance use.
Cannabidiol is a compound found in cannabis plants that is well tolerated, has low abuse liability, and might be an effective medication to promote tobacco cessation. This clinical study will use a validated approach for screening tobacco cessation medications to determine if oral cannabidiol increases short-term tobacco abstinence, and evaluate mechanisms that might explain how cannabidiol alters smoking behavior. Results from this study will provide data on the therapeutic potential of cannabidiol for tobacco cessation.
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 (Y-BTI) plus mobile phone automated text messaging (ATM) 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 the existing young adult Brief Tobacco Intervention (BTI) for youth. Roundtable discussions with students will identify salient intervention themes and strategies for targeting the Y-BTI intervention and developing the text messages. The second phase of the study evaluates the Y-BTI and ATM through a cluster randomized controlled trial that compares 4 treatment combinations: (1) Y-BTI + ATM, (2) Y-BTI alone, (3) ATM alone, or (4) no treatment control. It is hypothesized that the Y-BTI + ATM will produce greater abstinence at the 6-month follow-up compared to the Y-BTI alone, ATM alone or no treatment control. Further, it is hypothesized that the Y-BTI alone and ATM alone 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.
The overall objective of this project is to develop and obtain preliminary data on acceptability, feasibility, and initial efficacy of Native PATHS. This work is guided by the stage model guidelines for treatment development and adaptation 25. Stage 1a will occur in two sequential steps. First, the investigators will recruit youth who are in 5th - 8th grade and their family members (N=24, 12 youth, 12 adults 18+) to participate in three talking circle sessions to obtain feedback on the cultural adaptation and implementation of the treatment. Next, the investigators will conduct an open label pilot (N=9). Youth and their family members, (up to 3 per youth) will provide qualitative and quantitative feedback after each session. In Stage 1b, 60 youth will participate in a pilot randomized controlled trial, testing the efficacy of the newly created program (n=30) against a wait list control (WLC) condition (n=30). Ultimately, this program of research is expected to result in a well-specified, efficacious prevention program that could be readily disseminated and generalizable to other Indigenous populations with minimal adaptation.
