Smoking is the leading cause of preventable death in the United States. An FDA-mandated reduction in the nicotine content of cigarettes might reduce the health burden of tobacco by reducing the prevalence of smoking. The proposed project will test the impact of nicotine reduction on smoking behavior and smoke exposure in a setting where participants are restricted from using their usual brand cigarettes.
The purpose of this study is to investigate the impact of different nicotine levels in cigarettes with individuals who have ADHD.
RATIONALE: Computer-assisted scheduling of nicotine inhaler use may be an effective method to help people stop smoking. PURPOSE: Randomized cinical trial to compare the effectiveness of computer-assisted scheduling of nicotine inhaler use with that of self-scheduled nicotine inhaler use in participants who plan to stop smoking.
This is a 2-year study involving the progressive reduction in the nicotine content of cigarettes. The investigators believe that at the end of the study smokers of cigarettes with progressively reduced nicotine content will be "weaned" from nicotine. At the end of the study, the result will be a decreased level of nicotine dependence. When smokers are again free to choose any smoking behavior, they will smoke fewer cigarettes and/or have a greater interest in quitting compared...
The dose-effect curve to estimate a threshold delivery rate for reinforcement. The project addresses the FDA Center for Tobacco Products (CTP) interest #1: Nicotine dependence threshold among youth and adults and impact of nicotine reduction on tobacco product use behavior (e.g., topography, compensation, switching, multiple use, initiation, cessation and relapse). IV nicotine, in contrast to ECs, can deliver precise, reproducible dosing, which is necessary for accurately asses...
The purpose of this study is to test the success rate of smoking reduction or cessation with different nicotine products.
At any given point in time, most smokers are not interested in making a serious quit attempt. Data suggest that 30% of smokers have no plans to quit, 30% plan to quit at some future date, 30% plan to quit in the next 6 months, and about 10% plan to quit in the next month. While ~40% of smokers make a quit attempt each year, only about 4-6% of those achieve long-term success. This means that of the more than 60 million Americans who smoke, only 1 million are able to quit each ye...
To evaluate the safety, smoking cessation and reduction rate during 3 months of active nicotine replacement therapy (NRT) and a follow-up period of 3 months in smoking hospital physicians and staff who are motivated to quit
The purpose of this study is to evaluate the effect of a combination of the 21 mg nicotine patch and nicotine-free cigarette compared to 21 mg nicotine patch only and nicotine-free cigarette only on abstinence and withdrawal symptoms. The study will determine if adding nicotine replacement medication to the nicotine-free cigarettes will augment treatment compared to nicotine patch only or to nicotine-free cigarettes only.
To determine if the mu opioid receptor gene (OPRM1) A118G polymorphism moderates the subjective-rewarding effects of intravenous (IV) nicotine in male and female smokers. The subjective effects of nicotine will be measured with a Drug Effects Questionnaire, including the ratings of "good effects" and "drug liking". We hypothesize that smokers with the AG/GG genotype for the OPRM1 A118G will have attenuated subjective-rewarding effects from IV nicotine when compared to those wit...
A placebo-controlled study to enroll male and female tobacco smokers menthol (n=35) and non-menthol (n=35) who will participate in five experimental sessions. subjects will be given an IV infusion of either saline or 1 mg nicotine at rapid, moderate or slow infusion rates (nicotine at 0.24,0.096, 0.048 and 0.024, mcg per kg body weight per sec).
This study is designed to examine how the nicotine content of cigarettes and the nicotine concentration and flavors in e-liquids influence responses to and use of these products in adolescent smokers. Participants will complete a total of six sessions (an in-person screening/baseline session and five lab sessions.
Randomized controlled trial of electronic cigarettes with nicotine, without nicotine, nicotine inhaler, and sham-control on endothelial function, oxidative stress and sympathetic nerve activity
A comparison of three products for oral nicotine replacement with respect to pharmacokinetics after multiple-doses of nicotine.
In our communications with the public, the investigators will call this the Not Quite Ready to Quit Smoking Study. One new method to increase quit attempts is to have smokers reduce their cigs/day. The investigators and others have shown that reduction aided by nicotine medications can increase quit attempts and later abstinence among smokers not ready to quit. Because half of smokers are reluctant to use nicotine medications for a non-cessation reason, the investigator...
The purpose of this study is to assess if access to an electronic nicotine delivery device, or e-cigarette, in addition to nicotine patch (21 mg) can help reduce cigarette smoking among individuals diagnosed with schizophrenia compared to nicotine patch alone.
The purpose of this study is to determine whether an adhesion reduction plan, consisting of early adhesion prevention and application of a bioresorbable membrane is effective in reducing the severity of adhesions and the incidence of complications in managing the open abdomen in trauma and emergency general surgery.
Since 1996, the nicotine patch has been re-classified from prescription to over-the-counter (OTC) status in the United States. Little is known about how the public uses the OTC nicotine patch due to lack of monitoring. The purpose of this observational study is to describe the characteristics of consumers who purchase OTC nicotine patches from community pharmacies and to determine the factors associated with the appropriate use of nicotine patches.
The investigators hypothesize that African Americans (AAs) smoke more for positive reinforcement from nicotine with a "peak-seeking" pattern of smoking (smoking individual cigarettes more intensively with greater intake of nicotine and tobacco smoke toxins), while whites smoke more for negative reinforcement with a "trough-maintaining" pattern (avoiding withdrawal by maintaining more consistent nicotine levels throughout the day by means of a more regular smoking pattern). The ...
A comparison of three products for oral nicotine replacement with respect to pharmacokinetics after single-dose of nicotine.
In this study, smokers will be randomly assigned to one of three conditions for six weeks: 1) nicotine-free cigarettes (0.05mg); 2) extra low nicotine cigarettes (0.3 mg); or 3) medicinal 4 mg nicotine lozenge. The tobacco toxin profiles across these various products will be compared. The effects of these products on biomarkers of exposure and risk factors for disease, compensatory smoking, components of tobacco addiction and short-term smoking cessation will be determined. P...
This study examines the potential effect of reducing nicotine content or menthol or both in women of reproductive age, a vulnerable population identified by the FDA in need of further research.
The purpose of the study is to compare the pharmacokinetic (PK) profiles and assess bioequivalence between a new nicotine lozenge and a reference nicotine lozenge in healthy smokers
The purpose of the study is to compare the pharmacokinetic (PK) profiles and assess bioequivalence between a new nicotine lozenge and a reference nicotine lozenge in healthy smokers.
Unfortunately, the investigators still need to assess and identify novel ways to help people quit smoking. Differences between people in terms of how fast they metabolize nicotine influences response to transdermal nicotine patches, the most popular nicotine dependence treatment, and it affects plasma levels of nicotine from treatment. These studies suggest that fast metabolizers of nicotine may show better quit rates if they receive higher doses of transdermal nicotine. This p...
