Nicotine is the most commonly abused drug among individuals with schizophrenia; at least 60 percent of schizophrenics smoke cigarettes. Nicotine withdrawal may cause a temporary worsening of schizophrenia symptoms, making it especially difficult for these individuals to quit smoking. Little research has been done on the most effective way to control nicotine use in schizophrenic individuals. Transdermal nicotine and bupropion reduce smoking in non-psychiatric smokers, but little is known about the effects of these medications in smokers with schizophrenia. This project examines the effects of 0, 21 and 42 mg transdermal nicotine on smoking behavior and related subjective effects (urge to smoke and nicotine withdrawal symptoms) in smokers with schizophrenia and non-psychiatric heavy smoking controls. Participants come to the laboratory at 9 am, at which time placebo or nicotine patches are applied. After 5 hrs of smoking abstinence, participants undergo a smoking cue reactivity assessment in ...

It is widely accepted that nicotine replacement therapy can help patients to quit smoking. Recent approval by the US Food and Drug Administration of a nicotine nasal spray gives clinicians greater flexibility in choosing the best replacement therapy for a particular patient. Four types of smoking cessation therapy are currently available (gum, patch, nasal spray, and bupropion). These differ with respect to their onset and duration of action, adverse effects, and cost. This article focuses on which patients may benefit most from the use of nicotine nasal spray. Instructions for proper administration and dosing of the nicotine nasal spray are discussed as well as how to taper it appropriately, and how to avoid--and manage--adverse effects. Additionally, the cost of the nicotine nasal spray is reviewed and compared with over-the-counter products and bupropion. Resources for behavioral support are provided as well. ...

Nicotinic alpha7- or beta2-containing receptor knockout: effects on radial-arm maze learning and long-term nicotine consumption in mice.

This cross-sectional analyses of tobacco exposure during the same period as toenail collection indicates that toenail nicotine levels can be informative biomarkers for the assessment of exposure to tobacco smoke. Women who were not active smokers who were exposed to ETS had higher nicotine levels than nonexposed individuals, but both categories of nonsmokers had much lower nicotine levels than active smokers. Nicotine levels of passive nonactive smokers overlapped with those of active smokers, which supports the hypothesis that exposure to passive smoking can be a significant source of exposure that is usually not accounted for in studies of adverse health effects of active smoking based on questionnaire measurements only.. The limitations of validating a new biomarker with an imperfect one such as questionnaire in this case are well known. Although the two measures were highly correlated, nail nicotine was less strongly correlated with questionnaire reports of passive smoking. Given the many ...

VALENCA, Samuel Santos; GOUVEIA, Lucas; ALVES PIMENTA, Wagner y PORTO, Luís Cristóvão. Effects of Oral Nicotine on Rat Liver Stereology. Int. J. Morphol. [online]. 2008, vol.26, n.4, pp.1013-1022. ISSN 0717-9502. http://dx.doi.org/10.4067/S0717-95022008000400037.. Nicotine is the more abundant component in cigarette smoke. Because nicotine is first metabolized in the liver, our aim was to investígate the effects of nicotine on this organ by biochemical and stereological methods. Male Wistar rats were treated with oral nicotine (ON) diluted in drinking water during 32 days. The control group was treated with drinking water in the same period. Rats were sacrificed 24 hours after last day, the blood was collected and the liver was removed. Lipidogram was performed by enzymatic method and collagen fibers, fat globules and hepatocytes were count in the liver by stereological methods. We observed in control group preserved hepatocytes, with no presence of inflammatory cells. However in the ON ...

Mecamylamine is a nicotine antagonist (that is it blocks the effect of nicotine). The rationale for its use in smoking cessation is that it may block the rewarding effect of nicotine and thus reduce the urge to smoke. The objective of this review was to determine the effectiveness of mecamylamine in promoting smoking cessation, either alone or in combination with nicotine replacement therapy. We searched the Cochrane Tobacco Addiction Group trials register. Randomised trials of mecamylamine, either alone or in combination with nicotine replacement therapy, which reported smoking cessation rates at least six months after intervention. We extracted data in duplicate on the type of subjects, the dose and duration of the mecamylamine and nicotine treatments, side-effects of treatment, the outcome measures, method of randomisation, and completeness of follow-up. The main outcome measure was sustained abstinence from smoking (biochemically validated) after at least six months follow-up in patients ...

Do not use any other nicotine products with the nasal spray. This includes nicotine patches, lozenges, or gum. You may have serious unwanted effects if you use more than one nicotine product. Pregnant women should only use this medicine as directed by a doctor. Cigarette smoke can seriously harm your child. Try to stop smoking without using medicine. The risks to your child from this medicine are not fully known. Nicotine products must be kept out of the reach of children and pets. Small amounts of nicotine can cause serious unwanted effects in children, and a used bottle may contain enough nicotine to cause problems. If the spray bottle is touched by a child, contact your doctor or poison control center at once. During the first week, you may have a hot, peppery feeling in your throat or nose, coughing, a runny nose, sneezing, or watery eyes. Do not stop using the medicine. If you continue to use the nasal spray, you should adjust to these effects. If these effects do not lessen after several ...

Q: After 30 years of smoking, I quit the habit 12 years ago. Since then, Ive been chewing about 15 pieces of nicotine gum every day. Can you tell me how this might be affecting my health? Im in good health overall, but my HDL is still too low despite daily exercise and taking 4,800 milligrams of fish oil daily. A: The good news is that by stopping smoking, youve significantly reduced your risk of heart disease and cancer, especially lung cancer. The not-so-good news is that continued, long-term use of nicotine-replacement therapy could potentially cause other health problems. The purpose of nicotine gum is to deliver small doses of nicotine to your body, which allow you to better manage your withdrawal symptoms and cravings as you quit smoking. When you smoke, you inhale nicotine and more than 4,000 harmful chemicals. More than 60 of those substances are known to cause cancer. Replacing smoking with a pure nicotine alternative, such as nicotine gum, eliminates all those other chemicals, and ...

N2 - Prenatal nicotine exposure impairs normal lung development and leads to diminished pulmonary function after birth. Previous work from our laboratory has demonstrated that nicotine alters lung development by affecting a nonneuronal cholinergic autocrine loop that is expressed in lung. Bronchial epithelial cells (BECs) express choline acetyltransferase, the choline high-affinity transporter and nicotinic acetylcholine (ACh) receptor (nAChR) subunits. We now demonstrate through a combination of morphological and electrophysiological techniques that nicotine affects this autocrine loop by up-regulating and activating cholinergic signaling. RT-PCR showed the expression of α3, α4, α7, α9, α10, β2, and β4 nAChR mRNAs ...

Osteopontin (OPN) is a secreted phospho-protein that confers on cancer cells a migratory phenotype. We have recently shown that nicotine, a risk factor in pancreatic ductal adenocarcinoma (PDA), induces an alpha7-nicotine acetylcholine receptor (α7-nAChR)-mediated increase of OPN in PDA cells. In this study, we tested nicotines effect on the expression of OPN splice variants (OPNa, b, c) in PDA cells. We also analyzed the correlation between patients smoking history with OPN and α7-nAChR levels. RT-PCR and UV-light-illumination of ethidium-bromide staining were used to examine the mRNA expression in tissue and PDA cells treated with or without nicotine (3-300 nM). Localization of total OPN, OPNc and α7-nAChR was analyzed by immunohistochemistry, and their mRNA tissue expression levels were correlated with the patients smoking history. PDA cells expressed varying levels of OPNa, OPNb, and α7-nAChR. Nicotine treatment selectively induced denovo expression of OPNc and increased α7-nAChR expression

Nicotine Replacement Therapy (NRT) A variety of formulations of nicotine replacement therapies (NRTs) now exist, including the transdermal nicotine patch, nicotine spray, nicotine gum, and nicotine lozenges. Because nicotine is the main addictive ingredient in tobacco, the rationale for NRT is that stable low levels of nicotine will prevent withdrawal symptoms-which often drive continued tobacco use-and help keep people motivated to quit. Research shows that combining the patch with another replacement therapy is more effective than a single therapy alone.

Pre-existing cognitive and mood disorders may influence the development and maintenance of nicotine dependence.[22] Nicotine is a parasympathomimetic stimulant[11] that binds to and activates nicotinic acetylcholine receptors in the brain,[12] which subsequently causes the release of dopamine and other neurotransmitters, such as norepinephrine, acetylcholine, serotonin, gamma-aminobutyric acid, glutamate, endorphins,[23] and several neuropeptides.[24] Repeated exposure to nicotine can cause an increase in the number of nicotinic receptors, which is believed to be a result of receptor desensitization and subsequent receptor upregulation.[23] This upregulation or increase in the number of nicotinic receptors significantly alters the functioning of the brain reward system.[25] With constant use of nicotine, tolerance occurs at least partially as a result of the development of new nicotinic acetylcholine receptors in the brain.[23] After several months of nicotine abstinence, the number of receptors ...

Objectives: To evaluate nicotine delivery from the NJOY® King Bold Electronic Nicotine Delivery System (ENDS) and its short-term potential for smoking reduction or cessation. Methods: One week of ad libitum use was followed by measurements of plasma nicotine, heart rate, and craving and withdrawal after 12 hours of nicotine abstinence in 25 adult smokers not interested in quitting. Results: After 5 minutes of use, blood nicotine levels increased by a mean of 3.5 ng/mL (p < .001), heart rate increased, and craving was reduced by 55%. Cigarettes per day were reduced by 39% during the test week, and perceptions of use for reduction or cessation were positive. Conclusions: The NJOY® King Bold ENDS delivers nicotine and led to short-term smoking reduction ...

Background: Given the rapid increase in the popularity of e-cigarettes and the paucity of associated longitudinal health-related data, the need to assess the potential risks of long-term use is essential.. Objective: To compare exposure to nicotine, tobacco-related carcinogens, and toxins among smokers of combustible cigarettes only, former smokers with long-term e-cigarette use only, former smokers with long-term nicotine replacement therapy (NRT) use only, long-term dual users of both combustible cigarettes and e-cigarettes, and long-term users of both combustible cigarettes and NRT.. Design: Cross-sectional study.. Setting: United Kingdom.. Participants: The following 5 groups were purposively recruited: combustible cigarette-only users, former smokers with long-term (≥6 months) e-cigarette-only or NRT-only use, and long-term dual combustible cigarette-e-cigarette or combustible cigarette-NRT users (n = 36 to 37 per group; total n = 181).. Measurements: Sociodemographic and smoking ...

For the primary goals, we hypothesize that 1) the oral tobacco product will be more efficacious than the medicinal nicotine product in substituting for smoking cigarettes; 2) among non-abstainers, the oral tobacco product will lead to greater reduction in cigarette smoking than medicinal nicotine; and 3) a higher rate of oral tobacco compared to medicinal nicotine use will be observed during and beyond the treatment period.. For the secondary goals, we hypothesize that 1) both products will equally reduce withdrawal symptoms and negative affect from cigarette abstinence, but smokers who are assigned to the oral tobacco product will be more likely to report liking the effects from their assigned product compared to those smokers assigned to medicinal nicotine; 2) greater physiological effects (e.g., vitals) will be observed for the oral tobacco product compared to medicinal nicotine; 3) the toxicant exposure and toxicity will be reduced dramatically when smokers switch from cigarettes to each of ...

Tobacco and nicotine use are associated with numerous adverse health effects including miscarriage, preterm birth, low birthweight, placenta previa, placental abruption, cleft lip and palate, and sudden infant death syndrome (SIDS). Babies exposed to secondhand smoke have increased risk of ear infections, asthma complications, and SIDS (Centers for Disease Control and Prevention [CDC], 2016). Prevalence of all forms of nicotine use among pregnant women in the United States is unknown; however, 8.4% of women report smoking at some time during pregnancy (Curtin & Matthews, 2016). Cigarette smoking has declined among adolescents, though use of electronic cigarettes and hookah has increased (CDC), thus screening for new and emerging tobacco products is increasingly important. Familiarity with the many types of tobacco and nicotine should guide screening questions, for example, instead of asking a woman if she smokes cigarettes, nurses might ask, Do you use any type of tobacco or nicotine? or Do ...

I personally gave up smoking last year -after 20 long years of being a smoker. I was extremely lucky that I met Cindy from http://www.cindygalvin.co.uk who uses a method call RTT hypnosis and it worked extremely well for me. However, it seems hypnosis may not work for everyone, and if you are one of those who is not so lucky, another way to give up smoking is by using nicotine patches.. Here is a brief overview of nicotine patches with a detailed list of side effects:. The nicotine patch is a safe and effective method to use in smoking cessation. They are made in several different strengthsusually 21mg, 14 mg, and 7mgand can accommodate the occasional or chain smoker. These patches work by delivering a steady stream of nicotine into your system that curbs your cravings and allows you to gradually lower the dosage until you no longer need them. Each box contains 14 patches and the dosage is recommended depending on how many cigarettes you smoke per day. There are,however, some side effects to be ...

Author(s): Anthenelli, Robert M; Benowitz, Neal L; West, Robert; St Aubin, Lisa; McRae, Thomas; Lawrence, David; Ascher, John; Russ, Cristina; Krishen, Alok; Evins, A Eden | Abstract: Substantial concerns have been raised about the neuropsychiatric safety of the smoking cessation medications varenicline and bupropion. Their efficacy relative to nicotine patch largely relies on indirect comparisons, and there is limited information on safety and efficacy in smokers with psychiatric disorders. We compared the relative neuropsychiatric safety risk and efficacy of varenicline and bupropion with nicotine patch and placebo in smokers with and without psychiatric disorders.We did a randomised, double-blind, triple-dummy, placebo-controlled and active-controlled (nicotine patch; 21 mg per day with taper) trial of varenicline (1 mg twice a day) and bupropion (150 mg twice a day) for 12 weeks with 12-week non-treatment follow-up done at 140 centres (clinical trial centres, academic centres, and outpatient clinics

Most smokers become nicotine dependent and, when they stop smoking, experience withdrawal symptoms and craving. Nicotine replacement therapy (NRT) reduces these unpleasant symptoms and, theoretically, should decrease the risk of relapse. Smoking cessation is properly defined as validated sustained abstinence from cigarettes and/or other tobacco products for at least 6 months, but preferably for 1 year. This editorial includes evidence only from those studies which have applied such a definition and which have specified their settings and populations.. NRT is available as chewing gum, transdermal patches, sublingual tablets, lozenges, inhalation cartridges and nasal spray. In specialised cessation clinics1-8 and in primary care,9,10 prospective randomised clinical trials have shown that NRT, used as an adjunct to advice and support, results in better cessation rates than does advice and support alone. In the clinics success rates with NRT tend to be higher (11-30%) and more consistent than in ...

E-cigarette-only use and dual-use are emerging behaviours among adolescent nicotine product users which have not yet been sufficiently explored. This study examines the prevalence of, and the factors associated with, nicotine product use in adolescence. The study is a cross-sectional analysis of the 2018 Planet Youth survey completed by 15–16 year olds in the West of Ireland in 2018. The outcome of interest was current nicotine product use, defined as use at least once in the past 30 days. A main effects multinomial logistic regression model was used to examine the association between potential risk and protective factors and nicotine product use. Among 4422 adolescents 22.1% were current nicotine product users, consisting of 5.1% e-cigarette only users, 7.7% conventional cigarette only users, and 9.3% dual-users. For risk factors, the odds of association were weaker for e-cigarette only use compared to conventional cigarette and dual use. Participating in team sport four times/week or more

Tobacco-specific mitogen, nicotine, was reported to correlate with cancer progression on gastric cancer. Since metastasis is the major cause of cancer death, the influence of nicotine on the migration of gastric cancer cells remains to be determined. Materials and Methods: The influence of nicotine on migration of gastric cancer cells was evaluated by transwell assay and wound-healing migration assay. Receptor-mediated migration was studied by both inhibitor and small interfering RNA. ...

The cholinergic agonists nicotine, muscarine, or arecaidine at increasing 10 − 6, 10 − 5, and 10 − 4 (only muscarine) m concentrations were superfused over the receptive fields for 5 min at 10 min intervals. Nicotinic receptors (nAhRs) are a group of cholinergic receptors that also interact with nicotine in tobacco. Nicotinic and muscarinic receptors are the two main types of cholinergic receptors. Nicotinic receptors are the receptors in which the agonist is nicotine, and are ligand-gated ion channels in which neurotransmission is facilitated. What is the difference between Muscarinic and Nicotinic receptors (apart from there sensitivity to Muscarine and Nicotine)? Nicotine occurs throughout the tobacco plant and especially in the leaves. A large number of physiological functions such as heart rate and force, the release of neurotransmitters, and contraction of smooth muscles are mediated by muscarinic receptors. Most IPSPs are attributable to the. En los cigarros puros y en el tabaco de ...

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Objective: The immune response to an inflammatory stimulus is balanced and or-chestrated by stimulatory and inhibitory factors. After a thermal trauma, this balance is disturbed and an excessive immune reaction with increased production and release of proinflammatory cytokines results. The nicotine-stimulated anti-inflammatory reflex offsets this. The goal of this study was to verify that transdermal administration of nico-tine downregulates proinflammatory cytokine release after burn trauma. Methods: A 30 % total body surface area full-thickness rat burn model was used in Sprague Dawley rats (n = 35, male). The experimental animals were divided into a control group, a burn trauma group, a burn trauma group with additional nicotine treatment, and a sham + nicotine group with 5 experimental animals per group. The last 2 groups received a transdermal nicotine administration of 1.75 mg. The concentrations of tumor necrosis factor

Nicotine is recognized as the tobacco component that is responsible for most if not all of the addictive nature of tobacco. In mainstream tobacco smoke (MTS), the amount of nicotine that is in the free-base form is generally believed to be well correlated with physical â impactâ , â strengthâ , and â harshnessâ of such smoke. There are also reasons to expect that the amount of free-base nicotine may be related to the addictiveness of tobacco smoke. Evidence from previously secret tobacco industry documents indicates that ammonia-producing compounds have been added to cigarette tobacco as â impact boostersâ . Knowledge of the acid/base chemistry of tobacco smoke is required for a proper understanding of the effect of ammonia additives on nicotine chemistry in MTS. The goal of this work was to improve our understanding of this chemistry by studying the interdependent gas/particle (G/P) partitioning of nicotine and ammonia in MTS, including the study of components in MTS that are related

Rats were trained in a two-lever food-reinforced operant task to discriminate (+)-amphetamine (1 mg/kg) from saline. After discrimination training stabilized, test doses of (+)-amphetamine (0.0625-2.0 mg/kg), (-)-nicotine (0.1-1.0 mg/kg), or (-)-nornicotine (1-10 mg/kg) were assessed for their ability to substitute for the (+)-amphetamine training dose during brief test sessions in which food reinforcement was withheld. As expected, as the test dose of (+)-amphetamine increased, there was a dose-related increase in drug-appropriate responding, with both 1 and 2 mg/kg test doses substituting fully for the (+)-amphetamine training dose. Both (-)-nicotine and (-)-nornicotine showed partial substitution (approximately 50% drug-appropriate responding) for the (+)-amphetamine training dose, with (-)-nicotine being more potent than (-)-nornicotine. Rate suppressant effects prevented the assessment of higher doses of (-)-nicotine or (-)-nornicotine. Thus, while (-)-nicotine and (-)-nornicotine share ...

The toxicities and oxidative stress-inducing actions of (−)-nicotine and smokeless tobacco extract (STE), containing equivalent amounts of nicotine, were studied. Toxicities were determined by colony formation assays using Chinese hamster ovary (CHO) cells. Results indicated that nicotine is less toxic than smokeless tobacco extract that contained the same amount of nicotine. The generation of reactive oxygen species, following treatment with smokeless tobacco extract and nicotine, was assessed by measurement of changes in glutathione (GSH) and malondialdehyde (MDA) levels. CHO cells (5 × 105 cells/5 ml media) were incubated with 4, 0.8, and 0.08 mg of nicotine and STE containing the same amounts of nicotine. All preparations of smokeless tobacco extract significantly decreased GSH levels and increased MDA generation. However, 0.08 mg of nicotine treatment did not result in a significant change in GSH level, and only 4 mg of nicotine were sufficient to increase MDA generation. Addition of free

Smoking is highly correlated with enhanced likelihood of atherosclerosis by inducing endothelial dysfunction. In endothelial cells, various cell-adhesion molecules including E-selectin, are shown to be upregulated upon exposure to nicotine, the addictive component of tobacco smoke; however, the molecular mechanisms underlying this induction are poorly understood. Here we demonstrate that nicotine-induced E-selectin transcription in human aortic endothelial cells (HAECs) could be significantly blocked by α7-nAChR subunit inhibitor, α-BT, Src-kinase inhibitor, PP2, or siRNAs against Src or β-Arrestin-1 (β-Arr1). Further, chromatin immunoprecipitations show that E-selectin is an E2F1 responsive gene and nicotine stimulation results in increased recruitment of E2F1 on E-selectin promoter. Inhibiting E2F1 activity using RRD-251, a disruptor of the Rb-Raf-1 kinase interaction, could significantly inhibit the nicotine-induced recruitment of E2F1 to the E-selectin promoter as well as E-selectin ...

We present a novel model indicating that smoking more CPD, having greater total puff volume during ad libitum smoking, smoking menthol cigarettes, and being male were all significant predictors of greater daily nicotine exposure, as measured by TNE, in AA smokers. Consistent with research showing that actual smoking behavior correlated better with post-smoking nicotine blood level than machine indicated yield (33), we found that ones total puff volume per cigarette is an important predicator of daily nicotine exposure. Furthermore, the finding that males have greater nicotine exposure is supported by previous research indicating that males take in larger puff volumes (34).. The finding that menthol smokers yielded greater TNE is supported by some previous research, suggesting that menthol smokers take in greater puff volumes (35), but contradicts research from the Wang and colleagues (36) from Altria Client Services who found no significant differences in daily nicotine exposures in AA menthol ...

E-cigarettes or electronic nicotine delivery systems (ENDS) have recently attracted considerable attention for several reasons. Compared with combustible cigarettes, these (1) deliver nicotine without combustion, (2) are thought to be less toxic,1-8 (3) can be used to reduce nicotine craving/withdrawal,3 ,9-13 (4) tend to be less expensive2 ,3 ,8 ,14 ,15 and (5) can potentially help one quit combustible cigarette smoking/prevent relapse.1-4 ,6-8 ,15-21. While there is great variability in the design and performance of ENDS within and across brands, characterising features include the use of a battery or other power source, and a heating element that when activated delivers an aerosol mist from a solution most often containing tobacco-derived nicotine, flavourings and other ingredients.22 ,23 ENDS typically fall into three categories: disposable ciga-like products, rechargeable ciga-like products and larger rechargeable products (ie, personal vapourisers, tank systems). In addition to ...

Abstract: : Purpose: To examine the ability of nicotine, a compound known to be involved in stress-associated immunomodulation, to induce ocular viral shedding in rabbits latently infected with HSV-1 strain McKrae. Methods: New Zealand white rabbits latently infected with HSV-1 were randomly divided into two groups. One group received nicotine by transdermal patch (21 mg/d) for 20 days, the other served as a control. Reactivation data were obtained by detection of infectious virus in tear film collected by daily ocular swabs. The concentration of nicotine (mg/ml) in the serum was determined at 0, 1, 4, 8, 15, and 24 hrs after patch replacement. Results: Rabbits receiving nicotine exhibited a significantly (p=0.00001) higher rate of HSV-1 ocular shedding than controls. Compilation of data from three separate experiments demonstrated that 16.5% (258/1560) of the swabs taken from rabbits treated with nicotine were positive for virus, compared to only 8.3% (53/639) of swabs taken from controls. Peak ...

Cigarette smoking is the foremost modifiable risk factor for adverse pregnancy outcomes. Nicotine is a suspected fetal neuroteratogen. There is concern that nicotine may achieve toxic levels during pregnancy if nicotine replacement therapies are prescribed at doses used in the nonpregnant state. Ten healthy, volunteer, pregnant smokers received infusions of deuterium-labeled nicotine and cotinine during pregnancy and again postpartum. From blood and urine measurements, the following were determined: clearance (renal and nonrenal) of nicotine and cotinine, clearance of nicotine via the cotinine pathway (an indicator of CYP2A6 activity), and daily intake of nicotine from smoking. The clearance of nicotine and cotinine was significantly higher (60 and 140%, respectively), and the half-life of cotinine was much shorter (8.8 versus 16.6 h, P , 0.01) during pregnancy. Although plasma levels of cotinine were lower during pregnancy (119 versus 202 ng/ml, P , 0.05), daily intake of nicotine from smoking ...

Nicotine causes chemical and biological changes in the brain. Although it is less dramatic than heroin or cocaine, the strength of the addiction is just as powerful. It is a reinforcing drug, which means that users desire the drug regardless of the damaging effects.The human body builds a tolerance to nicotine and the effect of the drug is reduced over time. As a result, regular smokers can inhale greater amounts of smoke and toxins without showing immediate effects (ie. coughing, nausea).Nicotine is considered addictive because it alters brain functioning and because people use it compulsively. Addiction to nicotine is not immediate - it may take weeks or months to develop ...

INTRODUCTION: The α4β2 nicotinic receptor is of central importance in tobacco dependence, while the homomeric α7 receptor may also play a role. In this candidate gene study, we examine the association between 8 single nucleotide polymorphisms (SNPs) in genes coding for nicotinic acetylcholine receptor subunits α4 (rs1044396, rs2273504, rs2236196, and rs2273502), α7 (rs2133965 and rs4779969), and β2 (rs2072660 and rs2072661) and smoking abstinence in a cohort of quitters enrolled in a clinical trial of behavioral support. METHODS: Data were obtained from the Patch in Practice study, involving 925 smokers in the United Kingdom. All participants were given an 8-week course of 15 mg of transdermal nicotine replacement therapy and blood was taken for genotyping. RESULTS: Logistic regression analyses assessed the association between each selected SNP and smoking abstinence at 4, 12, 26, and 52 weeks. There were no statistically significant associations with smoking cessation success or nicotine intake

N2 - We have previously shown that acetaldehyde, a constituent of tobacco smoke, increases nicotine self-administration in adolescent, but not adult, rats. The aim of this study was to determine whether acetaldehyde influences other behavioral, endocrine, or neuronal responses to nicotine at either age. Juvenile (postnatal day (P) 27) and adult (P90) male Sprague-Dawley rats were treated with saline, acetaldehyde (16 μg/kg/injection × 2, i.v.), nicotine (30 μg/kg/injection × 2, i.v.) or a combination of acetaldehyde and ...
