Neural Substrates in Nicotine Withdrawal

This study will test the hypothesis that a medication called tolcapone (Brand Name: Tasmar) will help reduce cognitive problems that smokers experience when they quit. This study will also determine whether the benefits of this medication differ depending on a smokers' genetic background.


The Effect of Exercise on Acute Nicotine Withdrawal

The primary aim of this project is to test the effect of exercise on acute nicotine withdrawal. Acute nicotine withdrawal is characterized by a complex array of symptoms associated with increased risk of relapse among individuals attempting smoking cessation. The available remedies do not target all aspects of withdrawal. For example, pharmacologic treatments reduce withdrawal-based craving, but have no effect on cue-related craving, altered sleep, and mood disturbances during ...

Genetic Differences in Limbic Activation Associated With Nicotine Withdrawal

Objectives: - To evaluate neural correlates associated with emotional processing during nicotine withdrawal preferentially involving the amygdala and associated areas within the corticolimbic and mesolimbic circuitry. We hypothesize that relative to a pre-quit baseline, post-quit nicotine withdrawal will result in increased activity to negative emotional cues, in contrast to other cues, in one or more areas of interest, and particularly in the...


Efficacy of 2 Probiotics During Nicotine Replacement Therapy on Withdrawal Symptoms Associated With Smoking Cessation

Quitting smoking is a big decision, a decision to achieve better health. Trying to quit smoking can be stressful. The prospect of dealing with withdrawal symptoms, fear or failure to change the routine, can also be sources of stress. Withdrawal from nicotine is characterized by symptoms that include anxiety, irritability, hunger and cravings for more tobacco. Nicotine creates a dependency so that the body develops a need for a certain level of nicotine at all times. Unless tha...

Effectiveness of the Nicotine Patch in Suppressing Nicotine Withdrawal Symptoms in Women Versus Men - 1

Women typically have a more difficult time quitting smoking than men. Little research has been done to understand the differences between men and women that may cause this distinction. This study will assess whether the reduced effectiveness of nicotine replacement therapy in women is caused by gender differences in the withdrawal suppression induced by nicotine replacement therapy.

Innovative Interventions for Smoking Cessation

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.

The Effects of Nicotine Withdrawal on Reward Responsivity in Schizophrenia

It has been suggested that patients with schizophrenia smoke in order to produce amelioration of dysfunctional dopaminergic pathways allowing them to experience pleasure and satisfaction and overcome anhedonia. No studies have assessed the effects of nicotine withdrawal on reward responsivity in patients with schizophrenia. The investigators believe that an understanding of this is crucial if improved treatments for nicotine dependence are to be developed for this patient popul...

The Stress Responses of Fetuses and Infants Whose Mothers Smoked During Pregnancy

It is generally understood that smoking during pregnancy has deleterious effects on the developing fetus, although research on smoking during pregnancy has been limited in focus, with most studies focused on birth weight of newborns and children's behavioral disturbances. However, little is known about the neurobiological underpinnings of nicotine-related developmental deficits and even less is known about genetic and environmental factors that may exacerbate the risk for such ...

Nicotine Replacement Therapy in Nicotine-dependent Arrestees

Tobacco use affects more than 50% of adult arrestees, of which 70% are dependent on nicotine. However, they have no access to tobacco during detention in police cells. Nicotine withdrawal symptoms, that include irritability, anxiety and lack of concentration, may worsen the arrestee's health status during detention. Nicotine withdrawal is a treatable condition. Validated treatments in other situations than police custody include nicotine replacement therapy. This study i...

Clinical Pharmacology of Electronic Cigarettes

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.

Comparisons of Nicotine-Free Cigarettes, Extra Low Nicotine Cigarettes vs. Medicinal 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...

Effects of Transdermal Nicotine on Smoking, Craving and Withdrawal in People With Schizophrenia

Individuals with schizophrenia are three times as likely to smoke cigarettes as individuals without schizophrenia. While a great deal of research has been focused on smoking cessation programs for healthy individuals, little attention has been directed towards developing an effective smoking cessation treatment for schizophrenics. This project will evaluate the effects of 0, 21 and 42 mg transdermal nicotine on smoking, urge to smoke, and nicotine withdrawal symptoms after 5 hr...

Treatment for Nicotine Addiction in Women

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.

Mechanisms of the Nicotine Metabolism Effect on Tobacco Dependence

The purpose of the study is to learn more about tobacco dependence and nicotine metabolism in African-Americans and whites, by studying to see if how fast a person metabolizes nicotine (how the body breaks down nicotine into inactive compounds) affects how dependent they are on smoking cigarettes. The investigators believe that people with a faster rate of metabolism may have more severe nicotine withdrawal symptoms and also may have a harder time trying to quit smoking.

A Pilot Study Evaluating Nicotine Lozenges and Self Help

The investigators are hypothesizing that by offering both self-help materials and mailed nicotine lozenges we will be able to help increase tobacco abstinence rates among ST users, as well as decrease tobacco withdrawal.

Effects of Nicotine on Brain Opioid Receptors

A substantial body of evidence implicates the endogenous opioid system, and the mu opioid receptor (MOR) in particular, in the reinforcing effects of drugs of abuse, including nicotine. A single nucleotide polymorphism (SNP) in the mu opioid receptor gene (OPRM1 Asp40) is associated with the ability to quit smoking, as well as nicotine reward and withdrawal symptoms. However, the precise mechanism through which this SNP influences nicotine dependence remains unresolved. This po...

Translational Neuropsychopharmacology Research of Nicotine Addiction

This study will examine the effects of combining Varenicline (VRN) and N-acetylcysteine (NAC) on neural circuitry function and treating nicotine addiction. Healthy adult nicotine dependent cigarette smokers interested in quitting (n=110) will be randomized to one of four PBO-controlled conditions for 4 weeks: 1) VRN+NAC, 2) VRN+PBO, 3) NAC+PBO or 4) PBO+PBO. Following 1 week of medication, participants will be contingently reinforced for 3 days of smoking abstinence and be scan...

Naltrexone and Patch for Smokers

The aim of this study is to investigate the effects of naltrexone, alone and combined with nicotine patch, on responses of smokers to smoking cues after 10 hours of tobacco deprivation. Smokers who are not seeking treatment will be assigned to one of six conditions: They will receive either 50 mg of naltrexone or a placebo pill, and also will wear a nicotine patch that has 0, 21, or 42 mg of nicotine during the tobacco deprivation period. Both the day before the medication a...

Effects of e-Cigarettes on Nicotine Withdrawal

This behavioral pharmacology laboratory experiment will assess whether sweet (vs. non-sweet) flavored e-cigarette solutions reduce tobacco withdrawal symptoms and motivation to smoke among 40 smokers interested in trying e-cigarettes (for the first time) following 16-hours of nicotine abstinence. The study's experimental design will provide evidence of the causal effects of e-cigarette flavorings on a putatively critical factor for determining whether smokers continue e-cigaret...

Effect of Progesterone on Smoking Behavior in Male and Female Smokers

Past research on nicotine addiction has shown that changes in estradiol and progesterone hormone levels during menstruation may cause women to respond differently than men to nicotine. The purpose of this study is to examine the effects of progesterone on smoking behavior, nicotine withdrawal symptoms, and the reinforcing effects of smoking in men and women addicted to nicotine.

Effects of Intranasal Oxytocin on Cigarette Smoking

Socioemotional processing dysfunctions (i.e., disruptions in affective, cognitive, and neural processes that encode, interpret, and respond to socially and emotionally relevant stimuli) have been implicated in tobacco smoking and relapse, however this potential target for medication development has not been systematically examined. Evidence from animal and human laboratories indicate that administration of intranasal oxytocin enhances socioemotional processing and may be effica...

Effects of EVT 302 With or Without NRT on Craving and Withdrawal in Healthy Male Smokers Deprived of Cigarettes

This randomised, placebo-controlled study is designed to explore the effects of EVT 302 both with and without concomitant nicotine replacement therapy (NRT) on craving and withdrawal in smokers after short term deprivation of cigarettes.

Does Sweet Taste Potentiate Nicotine Cue Reactivity?

The investigators' aim is to test the prediction that sweet taste perception enhances the ability of nicotine to induce neural plastic changes in brain reward circuits to increase the saliency, liking and brain reactivity to the sight and vaporized flavor of electronic cigarettes (e-cigarettes).

Does Abstinence From E-cigarettes Produce Withdrawal Symptoms?

The purpose of this study is to see whether adults who use e-cigarettes every day experience symptoms of nicotine withdrawal when they stop using e-cigarettes for 6 days.
