BACKGROUND: Athina Markou and her colleagues discovered persistent changes in adult behavior following adolescent exposure to ethanol or nicotine consistent with increased risk for developing addiction. Building on Dr. Markou's important work and that of others in the field, researchers at the Bowles Center for Alcohol Studies have found that persistent changes in behavior following adolescent stress or alcohol exposure may be linked to induction of immune signaling in brain. AIM: This study aims to illuminate the critical interrelationship of the innate immune system (e...

A discussion about disadvantages of electronic cigarettes (e-cigarettes) has recently broken out. There are even opinions that they are as harmful as regular cigarettes. However, this has not been proved, and theoretical premises suggest that e-cigarettes should be definitely less harmful as while using them, tobacco is not burned and harmful substances, in particular carcinogens are not produced. Certain premises assume that e-cigarettes may be used as a new form of nicotine replacement therapy, but this has not been confirmed yet...

Nicotine use is one of the most common forms of drug addiction. Although L-type calcium channels (LTCCs) are involved in nicotine addiction, the contribution of the two primary LTCC subtypes (Cav1.2 and 1.3) is unknown. This study aims to determine the contribution of these two LTCC subtypes to nicotine-induced conditioned place preference (CPP) responses by using transgenic mouse models that do not express Cav1.3 (Cav1.3(-/-)) or contain a mutation in the dihydropyridine (DHP) site of the Cav1.2 (Cav1.2DHP(-/-))...

BACKGROUND: System change interventions for smoking cessation are policies and practices designed by organizations to integrate the identification of smokers and the subsequent offering of evidence-based nicotine dependence treatments into usual care. Such strategies have the potential to improve the provision of smoking cessation support in healthcare settings, and cessation outcomes among those who use them. OBJECTIVES: To assess the effectiveness of system change interventions within healthcare settings, for increasing smoking cessation or the provision of smoking cessation care, or both...

We recently reported molecules designed according to the multi-target-directed ligand paradigm to exert combined activity at human fatty acid amide hydrolase (FAAH) and dopamine receptor subtype D3 (D3R). Both targets are relevant for tackling several types of addiction (most notably nicotine addiction) and other compulsive behaviors. Here, we report an SAR exploration of a series of biphenyl-N-[4-[4-(2,3-substituted-phenyl)piperazine-1-yl]alkyl]carbamates, a novel class of molecules that had shown promising activities at the FAAH - D3R target combination in preliminary studies...

Despite the fact that electronic cigarettes (e-cigarettes) are rapidly growing in popularity and use worldwide, there is scarce scientific data on abuse liability among e-cigarette users, and about whether e-cigarette use is related to nicotine dependence or not. The aim of this study is to explore nicotine dependence levels in a sample of experienced e-cigarette users (n= 39) and to compare them with current tobacco cigarette smokers (n=42). We conducted several face-to-face interviews in order to assess sociodemographic and dependence related characteristics in both e-cigarette users and in smokers...

Although vaccination is a promising way to combat nicotine addiction, most traditional hapten-protein conjugate nicotine vaccines only show limited efficacy due to their poor recognition and uptake by immune cells. This study aimed to develop a hybrid nanoparticle-based nicotine vaccine with improved efficacy. The focus was to study the impact of hapten density on the immunological efficacy of the proposed hybrid nanovaccine. It was shown that the nanovaccine nanoparticles were taken up by the dendritic cells more efficiently than the conjugate vaccine, regardless of the hapten density on the nanoparticles...

OBJECTIVES: It is common practice to individualize smoking cessation pharmacotherapy based on clinical judgement and patient response. However, little has been documented about the use and outcomes of smoking cessation pharmacotherapy in 'real world' settings. This study examines factors associated with using smoking cessation pharmacotherapy and related outcomes among smokers with psychiatric and/or substance use disorders who completed an intensive tobacco treatment program within mental health and addictions services settings in Vancouver, Canada...

Altered DNA methylation in addiction-related genes may modify the susceptibility to alcohol or drug dependence (AD or ND). We profiled peripheral blood DNA methylation levels of 384 CpGs in promoter regions of 82 addiction-related genes in 256 African Americans (AAs) (117 cases with AD-ND codependence and 139 controls) and 196 European Americans (103 cases with AD-ND codependence and 93 controls) using Illumina's GoldenGate DNA methylation array assays. AD-ND codependence-associated DNA methylation changes were analyzed using linear mixed-effects models with consideration of batch effects and covariates age, sex, and ancestry proportions...

BACKGROUND AND OBJECTIVES: Adults with mental illness (MI) use combustible tobacco at increased rates and have greater difficulty quitting smoking. Given the increasing popularity of electronic cigarettes (e-cigarettes), their use by those with MI has important health implications. While preliminary evidence suggests potential benefits of e-cigarette use for those with MI, well-controlled, systematic research examining appeal, correlates, and consequences of e-cigarette use in this vulnerable population is lacking...

Importance: A relapse into nicotine addiction during abstinence often occurs after the reactivation of nicotine reward memories, either by acute exposure to nicotine (a smoking episode) or by smoking-associated conditioned stimuli (CS). Preclinical studies suggest that drug reward memories can undergo memory reconsolidation after being reactivated, during which they can be weakened or erased by pharmacological or behavioral manipulations. However, translational clinical studies using CS-induced memory retrieval-reconsolidation procedures to decrease drug craving reported inconsistent results...

Importance: Disrupted reward processing, mainly driven by striatal dysfunction, is a key characteristic of addictive behaviors. However, functional magnetic resonance imaging (fMRI) studies have reported conflicting results, with both hypoactivations and hyperactivations during anticipation and outcome notification of monetary rewards in addiction.

Importance: Recent research on addiction-related memory processes suggests that protracted extinction training following brief cue-elicited memory retrieval (ie, retrieval-extinction [R-E] training) can attenuate/eradicate the ability of cues to elicit learned behaviors. One study reported that cue-elicited craving among detoxified heroin addicts was substantially attenuated following R-E training and through 6-month follow-up. Objective: To build on these impressive findings by examining whether R-E training could attenuate smoking-related craving and behavior...

Currently-available antismoking medications have limited efficacy and often fail to prevent relapse. Thus, there is a pressing need for newer, more effective treatment strategies. Recently, we demonstrated that enhancing endogenous levels of kynurenic acid (KYNA, a neuroinhibitory product of tryptophan metabolism) counteracts the rewarding effects of cannabinoids by acting as a negative allosteric modulator of α7 nicotinic receptors (α7nAChRs). Since the effects of KYNA on cannabinoid reward involve nicotinic receptors, in the present study we used rat and squirrel monkey models of reward and relapse to examine the possibility that enhancing KYNA can counteract the effects of nicotine...

BACKGROUND: Growing evidence suggests that some individuals may exhibit symptoms of dependence on ultraviolet (UV) light, a known carcinogen, in the context of tanning; however, few studies have investigated predictors of tanning dependence (TD). OBJECTIVE: To identify predictors of tanning dependence (TD). METHODS: Non-Hispanics of European-ancestry who had previously participated in a case-control study of early-onset basal cell carcinoma completed an online survey to ascertain TD and other behaviors (alcohol dependence, nicotine dependence, seasonal affective disorder (SAD), exercise 'addiction', and depression)...
