Filter by:The proposed research is a longitudinal human lab study to examine how measures of abuse liability and product appeal vary by e-cigarette device type, and how these lab assessments may predict subsequent e-cigarette and other tobacco use behavior at 1,3, and 6 months. An additional aim is to evaluate e-cigarette safety and tolerability among smokers by device type.
The purpose of this study is to investigate the effects of nicotine metabolism on occupancy of [11C]-(+)-PHNO to DA 2/3 receptors in different brain areas during periods of abstinence and smoking during an abstinence. This will be a Positron Emission Tomography (PET) study and the radiotracer [11C]-(+)-PHNO (11C]-( + )-4-propyl- 3,4,4a,5,6,10b-hexahydro-2H-naphtho[1,2-b][1,4]oxazin-9-ol) will be used.
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 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.
The objective of this study is to examine the cognitive, immunological, and neurophysiological effects of transitioning from tobacco cigarettes to electronic cigarettes. The central hypothesis of this study is that this transition will be accompanied by a decrease in peripheral inflammation, which will lead to significant changes in the neurocircuitry underlying interoception and appetite.
Phase 3 Pilot Clinical Trial.
Cigarette smoking remains a significant public health concern. A magnetic field applied to the outside of the skull can produce electrical activity in the brain without significant pain or the need for anesthesia. Sessions of magnetic stimulation or superficial stimulation that does not reach the brain will be used to determine if magnetic stimulation can reduce cue-induced craving and cigarettes consumption in adult nicotine-dependent cigarette smokers. This project may lead to a new therapy for smoking cessation.
