Filter by:The purpose of this study is to assess an "adaptive" approach to smoking cessation pharmacotherapy. The protocol is designed to compare adaptive vs. standard approaches to two common smoking cessation pharmacotherapies - Varenicline (commonly known as Chantix) and the Nicotine Patch. The investigators hypothesize that participants allocated to adaptive therapy will show significantly higher biochemically confirmed 30-day continuous abstinence at 12 weeks post-Target Quit Day (TQD).
Smoking is the leading cause of morbidity and mortality in the U.S. Interventions that increase successful quit attempts among depressed smokers with chronic medical illnesses are particularly important for the VA healthcare system because rates of tobacco use, depression, and chronic medical illnesses are significantly higher among Veterans compared to the general population. Providing smoking cessation services augmented with mood management to Veterans via telephone may increase access to, and utilization of, evidence-based smoking cessation counseling and decrease rates of smoking-related complications for Veterans with chronic medical illnesses and depression. Yet, the reach of smoking cessation telephone counseling has been limited among populations with mental illness. The investigators intend to combine the potency of co-delivered mood management and reach of telephone-delivered interventions by testing the telephone delivery of behavioral mood-management for smoking cessation among smokers with depression and chronic medical illness.
This is a pilot human experimental study to evaluate whether the use of an e-cigarette affects lung function, exhaled CO levels, and quantitative tobacco cigarette consumption in active tobacco smokers. Subjects recruited from the Winchester Chest Clinic (WCC), Adult Primary Care Clinic (PCC) and the Smilow Cancer Hospital Smoking Cessation Service will be randomized to 1 of 2 groups: (1) nicotine patch and intensive counseling (standard care) plus nicotine e-cigarette; (2) nicotine patch and intensive counseling plus non-nicotine e-cigarette.
The purpose of this research study is to determine whether combining electronic nicotine delivery systems (ENDS) with nicotine patch treatment will augment abstinence rates compared to either treatment alone.
The purpose of this pilot randomized trial is to determine the feasibility of e-cigarettes and telephone counselling (compared to transdermal nicotine replacement and telephone counselling) as a harm-reduction tool that may lead to increased smoking cessation in the perioperative setting in smokers presenting for elective surgery at the San Francisco Veterans Affairs Medical Center. Secondary outcomes include acceptability of e-cigarettes over transdermal nicotine replacement, length-of-stay in the post-anesthesia care unit, hospital length-of-stay, postoperative complications within the first 30-days, and smoking status 8-weeks after randomization. This pilot study is designed to provide the preliminary data necessary to plan and fund a larger-scale randomized clinical trial that will assess the utility of e-cigarettes in achieving smoking cessation perioperatively. Our ultimate goal is to add to the limited existing data on the safety and efficacy of e-cigarette use in smoking cessation, specifically in the perioperative setting where the risks of continued smoking are great and the motivation to stop is high.
Previous findings indicate elevated risk for tobacco use among adults in California who are unemployed and seeking work. In a pilot study, tobacco use was associated with a longer duration of time out of work. This community-based participatory research study aims to deliver and evaluate the impact of a web-based job seeker tailored tobacco cessation intervention vs. a control group in the San Francisco Bay Area. This research investigates whether an employment-centered tobacco treatment intervention is efficacious in supporting abstinence and also associated with more timely engagement of employment.
The purpose of this study is to learn more about nicotine exposure and the safety of electronic cigarettes (EC). It will focus on the areas that are thought to most closely relate to the addictive potential of EC, namely: (1) EC as nicotine delivery devices, covering issues of nicotine intake and pharmacokinetics, temporal patterns of use and titration of nicotine; and (2) subjective effects of EC use, including relationship of use to reward, withdrawal and craving.
The purpose of this study is to use a medication tolcapone and or placebo to test if the symptoms of nicotine withdrawal lessens , and or changes in smoking urges, and mental reasoning in female smokers over a 72 hour period.
This study involves the use of personalized nicotine patch dosing as a treatment strategy for smokers who cannot quit smoking after 2 weeks of using the standard nicotine patch dose. Functional Magnetic Resonance Imaging scans will also be obtained from all study participants before and after treatment. The first aim of the study is to determine if the treatment method under investigation is safe and more effective at increasing quit rates in smokers who do not respond to standard therapy.The second aim is to determine if there are any treatment- or cessation-related changes in brain function.
This randomized clinical trial studies the effects of black raspberry compounds (phytochemicals) on the bacteria in the mouth (oral microbiome) of current smokers and non-smokers. The oral microbiome protects the body from pathogenic bacteria. Smoking alters the oral microbiome and may increase the susceptibility to cancer by modulating normal host-bacteria interactions. Black raspberry phytochemicals may protect the oral microbiome of smokers and may lower their risk of developing oral cancer.
